    I got one of these with my iMac and I love it, I have never had a computer with wireless anything so the wireless was amazing to me, the keyboard looks really good as well and compared to most keyboards the sound of hitting keys is very low. The batteries last a long time as well, I got my iMac in June and just changed the batteries last month and i use the iMac every day for at least 2-3 hours.

    Cool looking, but uncomfortable

    • Written by from Cambridge

    It's nice that the design and top-row function buttons mimic my macbook, and I like the wireless feature. But I don't recommend this for an everyday keyboard. It's totally the opposite of ergonomically friendly, as is the magic trackpad. I have both at my office and both are causing use-related stiffness and pain (9-5, M-F use, with macbook usage outside of those hours/days). I would prefer that my desktop keyboard be more comfortable than my laptop keyboard, but that is not the case. I wish Apple would offer more ergonomically friendly products.

    Love it but wish...

    • Written by from Gloucester

    I love my keyboard and have had it for a year. One tip though...don't put non-rechargable batteries in there after you have accidentally charged them. The chemicals inside the battery will ooze inside it hold. Other than that it is a lot of fun. Overtime there are some connection problems but it always connects after a couple of off and ons, but remember I have had this for a while. ANother tip...don't use the keyboard where there is no light or (if with an iMac) you will have to turn up the brightness and point it at the keyboard. (If with a iPad 2) Then forget typing. Turn on the light or you will have a painful time trying to guess where the keys are (unless you know it by heart). Apple needs to come out with a backlit keyboard. Lol. BUY THIS PRODUCT....I LOVE IT AND YOU WILL. WORKS WITH ANYTHING. 4stars haha 7 if possible! :)

    love the keyboard. it works beautifully. but it has a truly awful, toxic smell. i hope it will wear off. if anyone has solved this problem, i would love to hear how you did it. i tried contacting customer service, but the process was so long and cumbersome that i gave up.

    I got this a week ago and it's comfortable to use and it's easy to type but the problem is you are not able to use some keys yet this thing is so easy to connect to the iPad good price never lags when you press the keys it's perfect for a portable keyboard or to use it just for the iPad at home

    These are fabulous...and also serve as a remote shutter release!

    • Written by from Coral Gables

    I bought one of these for my iPhone, and it has been great for taking notes and replying to emails. I have also used it with my EeePC, which otherwise has a small keyboard. It works well for anything that communicates by Bluetooth. My wife loves hers for her new iPhone, and I'm about to order a third for my son, who has an iPhone and iPad. It works splendidly with either one.
    The keyboard is beautifully designed and runs for months on a pair of standard AA batteries. The on/off switch is unobtrusive and easy to access. Turning it off requires holding the switch for a few seconds until a small green light goes off, although it also can put itself to sleep.
    One of the great things I just discovered about the keyboard is that it can serve as a remote shutter release for the iPhone and iPad. When the Camera app is open, just press the F12 (volume up) key on the keyboard. It works from more than 20 feet away.

    where's the 10th star to rate this keyboard???

    • Written by from Calgary

    Oh my I cannot say enough good things about this keyboard I have had this for about 2 months now and the batteries still register at 100% (lithium)

    my magic track pad has had the batteries (charged/replaces 3 times already)

    only complaint from the old wired one is the keypad with the digital and math signs, it makes calculator a littler tougher to use highly recommends as a replacement for your iMac/Macbook or for your iPhone/iPad/iPod touch this is amazing

    Go Apple Go !!!

    Very nice keyboard. It's very compact and the keys have a nice feel to them. Batteries lost quite awhile. It has a very modern look sitting on your desk, way better looking then the clunky black oversize pc keyboards. I only wish they built one with backlit keys.

    Great--but BATTERY HUNGRY!!!($)

    • Written by from St. Catharines

    This is a beautiful mouse--sleek, responsive...and wireless. Problem: It goes through batteries every couple of weeks. I am now trying to find something as comfortable, but unfortunately, w/ a wire. Even buying in bulk, I'll pay for a new mouse in no time w/ the money I save in not buying batteries. An environmental disaster...expensive...and frustrating when working on an important project. Never thought I'd give an Apple product a bad review. I hope I never have to again.

    Looks Ten, Types 3

    • Written by from Bloomington

    So this keyboard has a great look and feels like a laptop. This is not a good choice for doing a lot of typing as the keys are too close together and don't give enough feedback - either tactile or auditory - when you type. Useless for data entry. I thought Apple wanted to appeal to the business and scientific community. The separate aftermarket calculator has gotten only two stars.
    I made my own keyboard stand to put this keyboard in the proper angle and position to type with a wrist rest. Still not as good as some of the after market keyboards. Bluetooth can be buggy at times and depend on battery charge, USB less of a problem. If it came with an iMac, save it to use with your iPad, and buy an aftermarket wired keyboard if you do a lot of typing. I wouldn't buy it as a replacement keyboard.
    This is a case of form being subservient to function.

    Perfect companion keyboard for iPad

    • Written by from Cambridge

    Along with Pages, this keyboard really expands the capabilities of the iPad. It saves you from having to find a computer when you want to type up a long e-mail or document. Keyboard is very light, comfortable, and it automatically powers down when not in use. Battery life has not been an issue. Note: I have not tried any of the third party keyboards that are integrated into the iPad case. Regardless, if I lost this keyboard tomorrow, I'd turn right around and buy a new one without a second thought.

    Battery Drainer

    Simple, Thin, well-built

    • Written by from Rochester

    I recently purchased one of these for desktop-like uses for my Macbook. It functions very well. I can be 7 feet away from my charging macbook and still get good performance out of this keyboard. I have nothing to complain about. Battery consumption is relatively low based on how long I've had it. It was easy to adapt to since the only difference is that it isn't on my mac. One final thing is that it fits excellently on my keyboard tray allowing me to also put my magic mouse on the tray. Overall, its a very nice keyboard. I highly recommend it.

    Poor layout, some keys gone missing

    • Written by from pasadena

    This keyboard has only one Control key and that key is narrow and not in the lower-left corner. This makes editing in Emacs cumbersome.

    There are no page up/down keys. To scroll a text window by one page, one must hold the "fn" key and tap the up or down arrow key. This cannot be done with one hand, which makes it an accessibility issue.

    Two issues

    • Written by from San Jose

    Apple Wireless Keyboard has a very nice, refined, minimalistic design. It looks great in front of your Mac. It's also practical and easy to type.

    But there are two problems.

    Problem 1: It runs out of batteries quickly. I use this keyboard everyday at work. Before I leave, I turn it off to save batteries. But two AA batteries only last 1-2 months.

    Problem 2: It sometimes doesn't find the connection to my computer. When that happens, I turn it off and back on and move it around on my desk but I never know what I'm doing that makes or doesn't make it work.

Product Information

  • Overview

    More speed, more efficient workflow

    With lightning-fast speeds, immense five-disk capacity and proven LaCie reliability, the 5big Thunderbolt Series is the perfect complement to your Thunderbolt-compatible Mac, ideal for handling professional creative workflows. Get speeds of 785MB/s* thanks to five 7200rpm/64MB cache hard disks preconfigured in RAID 0. With these speeds, you have all you need for any post-production work.

    RAID flexibility for speed and security

    Thanks to its five disks, the LaCie 5big lets you custom make RAID configurations for your precise needs. Create a lightning-fast volume with three disks in RAID 0 and a safe volume with two disks in RAID 1. Hot-swappable disks** let you slide a new disk into the safe volume without switching off the device. The LaCie 5big can also be used as a JBOD array. With five working days a week, you can assign each disk to a daily backup. Support for JBOD makes the LaCie 5big the ideal backup companion to your Mac mini with OS X Server.

    Dual cooling system for long-term reliability

    The LaCie 5big's advanced dual cooling system ensures long-term reliability by preventing overheating. The system consists of three key components: an innovative heat-dissipating aluminium casing, a Noctua cooling fan and jumbo heat exhausts. Every aspect of this ultra-quiet cooling system makes the LaCie 5big perfect for even the most noise-sensitive creative environments.

    Designed for convenience

    Designed to integrate seamlessly into professional environments, with a small footprint and space-saving design, you can stand it alone or stack with multiple LaCie 5bigs.

    About Thunderbolt

    Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices via one simple port and a cable that carries both DisplayPort and PCI Express data. And it’s standard on every Mac.

    PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt, which means you can get PCI Express speed outside the box.

    Thunderbolt gives you up to 10 Gbps in both directions, allowing for super-fast data transfer between peripherals. You also have enough bandwidth to daisy-chain multiple high-speed devices without using a hub or switch.

    Thunderbolt also provides double the power of USB 3.0, delivering 10 watts to peripherals for improved performance on the go.

    • Dual Thunderbolt ports for daisy chaining

Durable, resistant leather?

After countless relocations and tosses on the table does the leather easily scratch? If yes are the scratches hopelessly obvious? Not that I plan to put it in direct sunlight, but does the leather dry or become choppy after let's say two years of use?

    Fantastic option for those of us with multiple devices that need overnight charging. I can charge my iPhone, my iPad and - through the USB charging port on the rear of the unit - my Amazon Kindle with one device. The USB port allows me to charge my bluetooth headphones and other accessories, as well. The alarm clock is loud and sound performance is solid.

This is a pretty good distraction to keep you busy for around an hour if you're into shooters, and a GREAT re-imagining of the original story to Yar's Revenge. This is a dual-analog on-rails shoot-em-up that's easy to pick up. The soundtrack is actually really good.

Alas, I don't think this game is worth $10. Be sure to keep an eye on it during the Steam sales, though.

Absolutely horrible controls! As a big on-rails shooter fan, I was vaguely looking forward to this, but it just plays so badly. Some interesting ideas, and it looks pretty good.

I'd say one of the worst aspects, even if only a subtle one, is the player and the on-screen gameplay feel... kind of detatched, as if the player doesn't exist in the same world, almost as if it's simply a video in the back ground that you can vaguely interact with.

All in all it's just kind of mediocre. I knew it was going to be bad after hearing the reviews of the xbox 360 version, but... it's not even 'so bad it's good', just really really bland. Avoid.

Free Societies in the Real World

Exclusive to STR

February 7, 2007

Civilization is sick and unhappy, and I claim that the root of it all is the unfree family. Children are deadened by all the forces of reaction and hate, deadened from their cradle days. They are trained to say nay to life because their young lives are one long nay.

   ~ A.S. Neill, Summerhill: A Radical Approach to Child Rearing (1960), page 102

Is a free and compassionate world even possible? It is easy to get caught up in feeling that such a world could never be. Tyranny, hatred, racism, and other such horror have always been commonplace. War has been in the news since before there was a news business, as have torture and unjust imprisonment. Physical and emotional cruelty to children have ever been the norm.

A healthy world can seem so distant, so far from what exists now, as to seem unreal in some way; a mere and foolish fantasy.

If you've been feeling that way lately, I have good news: free and healthy societies are not only possible and practical in the real world: they exist right now. Many of them, in fact. They are small, for the most part, but no less real or important for that.

I saw one of these societies, or part of it, while at the grocery store recently. A mother and four girls, maybe seven to twelve years old, were in line ahead of me. Two of the girls were daughters of the woman in line, the other two were, I think, friends, but the kids might have all been sisters.

What was special about this small group? Nothing, and yet everything. It was just a woman and some kids, standing in a check-out line at the market. The girls were talking and sometimes giggling, and the mom was talking with them occasionally, with obvious affection. The kids were lively and vivacious, enjoying each other's company in a natural and pleasing fashion, and being respectful of others in the line without being servile or sullen about it. Neither the mom nor the children seemed anxious, defensive, manic, angry, needy, controlling, or otherwise visibly neurotic. At one point the youngest stepped back while talking with her sister and banged her head on a display case; the sister hugged the young one's head to her chest and patted the child's hair, perfectly naturally, nothing overblown but with unforced and instinctive concern. The incident was over in a moment and the conversation went on as if nothing had happened.

No big deal, right? And yet, this group seemed a slice of heaven to me. All too often I see families and other groups or individuals who have had healthy, appropriate, and natural behavior and demeanor crushed out of them. I see children who have been disrespected so deeply that they have no respect for themselves or for others; I see parents who were hurt so badly in childhood that they cannot behave naturally or healthily with their own children. I see much worse, from time to time, and I imagine you do as well.

What I saw that day at the supermarket was nothing special, and yet it was the most important thing in the world. What I saw was a small group of emotionally healthy people enjoying each other's company – exactly what human beings were made for.

Real needs, engraved within us at the deepest levels, all have that same "big deal / no big deal" quality. Real needs are profoundly natural and thus easily taken for granted as long as the need is fulfilled – despite the pleasure we take in the fulfillment. But deprivation of what is truly needed creates crisis; if not resolved, the crisis leads to harm to the organism or worse. Consider this partial list of human needs:

Even a minute or two without air creates panic; death soon follows. Several days without water will kill a person, and not pleasantly. Starvation seems impossible to most in the developed world, yet millions die a slow death from lack of food every year. Lack of love, affection and connection with our parents and others early in life contributes – hugely, as it happens – to cancer, heart disease, diabetes, and other deadly ailments as well as to life-long misery and harmful behavior of almost every type, including depression and suicide. For that matter, an infant who is not loved at least enough to be fed, protected, and otherwise cared for will literally die. Lack of freedom (tyranny) killed hundreds of millions in the Twentieth Century, while ruining the lives of many times that with famine, unjust imprisonment, torture, needless poverty, and in dozens of other ways, including by simply breaking the hearts and spirits of millions.

That short list of needs is misleading, for the last two entries are really one. Loving someone includes respecting their freedom; to coerce a person (including a child) is to treat that person with un-love. Coercion actually erodes and destroys love; more of one always means less of the other. In similar fashion, love is necessary to any free society; a nation where love is lacking cannot long remain free, assuming it ever was. Even the market requires a widespread sense of connection (love) among the participants if it is to remain honest and workable; laws alone cannot replace the natural respect for others that comes from widespread emotional health – which is to say, from love.

As I have written before: Love and freedom are a single unit; a duality. Love includes freedom; freedom (in the human sense) includes love.

The real protection of life and property, always and everywhere, is the general recognition of the brotherhood of man.

   ~ Rose Wilder Lane , The Discovery of Freedom: Man's Struggle Against Authority, 1943*

My motto for the home, in education as in life, is this: For heaven's sake, let people live their own lives. It is an attitude that fits any situation.

   ~ A. S. Neill, Summerhill: A Radical Approach to Child Rearing, p. 123 (emphasis in original)

A nuclear family, an extended family, a school, a village, a town: all can be free and loving societies. So can the larger society of a nation or even the world as a whole, and indeed nations and the world as a whole will become free and loving – or at least much closer to that than they are now – and soon, or mankind will join the countless other species that have vanished into the mists of time.

Any group of human beings can be free and loving. I do not mean that people or societies can become healthy by sheer willpower; I wish they could, but that is not how people work, and even the largest societies are, for the most part, only groups of people.

Our experiences early in life determine the limits of our emotional health for the rest of our days; what we each make of that is up to us. I believe healthy change is possible on a personal level, but not widely or easily. Undoing neurosis is a worthy personal goal but not a method to pin one's hopes on for world-wide social change.

For that, we need something else. We need more love and freedom to grace the lives of the very young, and we need it as widely as possible. We need dramatic, radical change on an epic scale, and we need it yesterday.

It would seem that given a good start in life, almost any kind of stress can be withstood later on.

   ~ Arthur Janov, The Feeling Child, 1973, p. 144

. . . we must wake up to what our schools really are: laboratories of experimentation on young minds, drill centers for the habits and attitudes that corporate society demands. Mandatory education serves children only incidentally; its real purpose is to turn them into servants.

   ~ John Taylor Gatto, 'Against School', September 2003 Harpers Magazine

Among the most optimistic facts about human nature, given our current situation, is that small, simple changes early in life can provide enormous benefits that last a lifetime.

A healthy pregnancy without drugs, alcohol, or tobacco, and with a healthy diet supplemented by folic acid and other nutrients and with as little interpersonal and other stress as possible; a gentle birth; an affectionate infancy with the baby never banished to solitude; and a loving, non-violent, non-coercive relationship with the child at any age – such a start to life can overcome almost anything, and most of this can be provided by any parent.** Partners and extended family members can help; friends and neighbors and churches and charities and businesses can help. None of this involves rocket science or impossible actions. None of it requires coercive government, although as long as we are using government to penalize assault against adults, the same protection should certainly be extended to children.

Speaking of assault and coercion, America's long, cruel experiment with Prussian-inspired coercive "public education" is clearly as much a failure at educating children as it is a success at turning them into stunted little corporate drones and compliant, mind-addled subjects for the ruling elite to manipulate as it pleases.

What other group do we routinely force into twelve or more years of servitude, enforced by (in this case) truant officers? What other group is treated with the coercion, disrespect, and disdain that school children so often get from teachers and other school staff?

It doesn't have to be that way, and it shouldn't be that way. Treating children with respect – without violence or other coercion, and without neglect or emotional cruelty – is actually easier to do, because it makes for happy children who are pleasant to be with. It teaches children self-respect in a way no later workshop or pop-psychology book ever can. Treating children with respect (which includes insisting that they treat others with respect; as A. S. Neill pointed out, "freedom is not license") gives children a natural sense of responsibility and a comfortable understanding of how to deal with people in a healthy fashion.

Among the best short proofs of that (and what does it say about us that we would need proof that treating children well is a good thing?) is the British Government's own report on Summerhill School from 1949, which headmaster A. S. Neill included in his 1960 book on the school. The link will take you to the complete report, but for now I excerpt the report below, and as you read the material, keep in mind that it was written not by the headmaster or anyone else employed by the school but by British government employees. (Neill himself pointed out that "We were indeed lucky to have two broad-minded inspectors sent to us." That wasn't always to be the case later on; the British government tried to shut Summerhill down a few years ago; only a public outcry prevented it.)

Here is what the school and its children were like in that June of 1949, according to the British report (my emphasis below):

"The main principle upon which the School is run is freedom . . . . the degree of freedom allowed to the children is very much greater than the inspectors had seen in any other school and the freedom is real. No child, for instance, is obliged to attend any lessons. As will be revealed later, the majority do attend for the most part regularly, but one pupil was actually at this School for 13 years without once attending a lesson and is now an expert toolmaker and precision instrument maker. This extreme case is mentioned to show that the freedom given to children is genuine and is not withdrawn as soon as its results become awkward."

". . . the children are full of life and zest. Of boredom and apathy there was no sign. An atmosphere of contentment and tolerance pervades the School."

". . . the children's manners are delightful. They may lack, here and there, some of the conventions of manners, but their friendliness, ease and naturalness, and their total lack of shyness and self-consciousness made them very easy, pleasant people to get on with."

". . . initiative, responsibility and integrity are all encouraged by the system and that so far as such things can be judged, they are in fact being developed."

"Summerhill education is not necessarily hostile to worldly success."

The report backs up that last point with a list of degrees held and careers followed by former pupils. The obvious question here is: would you rather live in a world where people had been raised with love and freedom (whether at Summerhill or wherever), or the world as it is today?

Summerhill is a boarding school in England, but day schools run on similar principles exist in America and in several other nations as Sudbury schools, modeled after the original Sudbury Valley School in Framingham, Massachusetts (here's a list from the Sudbury Education Resource Network). Another alternative deserves mention here: home schooling.

Freedom and compassion are life itself; their lack is the road to death. That will become increasingly true in a literal, global sense as we move deeper into the 21st Century. The staggering, exponential increase in scientific knowledge and technology, which is only just beginning, has created a stark and urgent choice for mankind: A free and healthy world, soon, or a technologically empowered global tyranny – or perhaps even an extinction event for the human race.

Free and compassionate societies exist in the real world right now, as indeed they always have. The time has come to expand their size and number until they merge throughout entire nations and, eventually, the world as a whole.

Now or never.

Next week: How the Baby Boomers Almost Saved the World . . . and why they failed.

* Lane discusses three large-scale attempts at genuinely free societies: the Jews of Abraham; Mohammed and the Saracens who followed him; and the Americans who fought off British colonialism. While largely ignoring the flaws of each attempt, she does a spectacular and eye-opening job of presenting the case that each of these societies was, for at least a time (in the first two examples for quite a long time) free in a manner that has seldom been seen before or since. Rose Wilder Lane expressed the love and freedom duality in a powerful and artful way: "All men are brothers and each man is free."

There is a log file located at %windir%\Windowsupdate.log which should have all information about updates performed on the system. Alternatively you could check the Add/Remove programs dialog and check off the Show Updates checkbox to see which ones are installed.

However, WindowsUpdate.log can be deleted. So can the %WINDIR%\Software Distribution\ directory which contains WU downloads. Add/Remove Progs doesn't seem to contain all updates (for example, the Malicious Software Removal Tool). –  Umber Ferrule Mar 2 '10 at 17:18

I've just come across the following Microsoft web page which sheds some light on the question: Command-line switches for Windows software update packages

Under the heading, Overview of the installation process, it states:

  • The [hotfix] installation program registers the software update under one of the following registry keys:
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Updates\<operating system>\<service pack level>\KB<nnnnnn>
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Hotfix\Q<nnnnnn>
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Hotfix\KB<nnnnnn>

  • Removal information for the software update is stored in a hidden folder named:
    • $NtUninstallQnnnnnn$ or $NtUninstallKBnnnnnn$ in %Systemroot%

What is the best Windows Media Center Extender? I am debating if I should get an extender or hook directly to my video card. The video card method is going to be a pain to control and many of the remotes aren't that good. Is there a really good extender out there with a good remote as well as support for HDMI?

I wouldn't say it's the best by any stretch of the imagination, but I use the Apple TV. It works with anything that iTunes works with, so that includes Windows.

Its really easy to use, syncs with iTunes wirelessly and has a huge library of downloadable content, rentable, purchaseable, everything.

When I reboot my Windows 7 machine, I get the error:

Autochk cannot run due to an error caused by a recently
installed software package

The only way I can get rid of it is to boot from the Windows install DVD, get into command prompt and run chkdsk. Then when I reboot from the hard disk, there is no error, however, it eventually comes back.

Any ideas?

share|improve this question
The relevant error message will actually be on the line above that one. –  JdeBP Jan 3 '12 at 10:59
Did you ever manage to solve this problem? I'm currently in the same situation. –  tftd Dec 2 '12 at 17:04
@tftd, I eventually reinstalled Windows 7 and it no longer happens –  JoelFan Dec 2 '12 at 17:21
I actually found a solution to this without reinstalling - get a "Windows 7 Recovery Disk", boot from it, in the options you can choose "Start Command Prompt". In the Command Prompt type chkntfs C: /X and then chkdsk C: /F. With chkntfs you exclude your drive from being checked on boot and with chkdsk you force your drive to be checked now. It fixed my problem so far. If this helps anybody else, upvote and I'll post it as an answer. –  tftd Dec 2 '12 at 19:16

Hello i had this problem too... it is related to a corrupted usb***.sys file.

Check your recently installed software first and hardware... memory, hdd...

FIX: Boot from the Windows install DVD, get into command prompt and run "chkdsk X: /F" where X is the driver you have your system on.

share|improve this answer
That does solve the problem temporarily but then it comes back again eventually. –  JoelFan Jun 6 '10 at 12:59
If the usb**.sys is a file from Microsoft, then you can fix it with sfc /scannow when you have booted the system and go into the console. If it is not, then you should update the related drivers to the latest versions. @JoelFan: Please note that your problem could be unrelated with the mentioned file. –  Tom Wijsman Jul 17 '10 at 23:32

Use AutoRuns, look for the AutoChk line and disable it by removing the checkmark,
have caution when you decide to remove other things to optimize your boot as you could brick your OS.

It's safe to disable AutoChk, but you should scan sometimes so you don't run into unexpected problems.

share|improve this answer
add comment

You might be able to prevent autochk from running with Chkntfs ant the /x

but the bigger issue is why is your drive being flagged as dirty? Is the drive starting to die maybe. try running some HDD diagnostics on it. like WD lifeguard or the Seagate equivalent.

The fine print under these benchmark results refers to "preproduction Mac Pro 12-core 2.93GHz units," so I would say Xeon X5670.

Huh. My sleuthing was a waste of time. ;-) Apple's Press Release has the straight dope.

It indeed maxes out at two 2.93 GHz 6-core Intel Xeon X5670 processors (12-cores). Base configurations are one W3530 (BTO upgrade to W3565 or W3680) or two E5620 (BTO upgrade to X5650 or X5670).

Since the base 8-core model with E5620 processors starts at $3499 (US), and Intel sells the X5670 for over $1000 more, each, I'd be stunned to see a price less than $4999 on that bad boy. Apple might get a better deal for the X5670, but they will also add some margin.

Okay, so I have a hardware device that I have to connect to using putty. The device is protected by a 4 digit password. So I know there are 10,000 combinations and I know the device takes 5 seconds between each wrong password. So it'll take approx. 13 hours to complete.

How can I enter every combination into a putty window? I was thinking like a macro of some sort. Because the device I'm connecting to is like a hyper-terminal vt100 connection.

Update: When I connect to the device, I can interface with some things. But when I press 'E' to edit the MAP on the device. it tells me to enter the 4 digit password.

share|improve this question
I don't know the answer, but: PuTTY suggests Windows, and Windows supports other freeware SSH clients as well. Such as Cygwin, which opens up a world of scripting. Any reason why you specifically want PuTTY? –  Arjan Sep 11 '10 at 19:14
It's the only way I know how to connect to this device :-( It uses HyperTerminal or a VT100 emulator. –  Kelbizzle Sep 11 '10 at 20:00
Ok, so not necessarily PuTTY then. What about some other emulator that allows for scripting itself? Or, in the old days, many terminal programs allowed for reading a file with commands, to set the connection details et al, or to fetch data. Such command files might not allow for true scripting (such as writing loops). But generating a single (but huge) command file with all 10,000 possibilities might be much easier than trying to script PuTTY? –  Arjan Sep 11 '10 at 20:51
Aha, your question actually mentioned that VT100; I totally missed that, and so did others given the answers. When people see PuTTY, they think SSH, I guess. Why not remove PuTTY from the question...? –  Arjan Sep 11 '10 at 20:54
Yea, that makes sense. I went the single huge file route using autohotkey pastebin.ca/1938488 –  Kelbizzle Sep 11 '10 at 22:16

This might help. This is interfacing ssh using python. http://www.linuxplanet.com/linuxplanet/tutorials/6618/1/ Shouldn't be difficult to learn if you know python. You can do it on cygwin.

How could i have forgotten expect???? Use autoexpect to generate a script and then use some scripting lanaguage to substitue different passwords and you're done.

Tera Term Pro is a terminal emulator that can connect to a serial port and has a macro language.

In Tera Term Pro, go to HelpIndexMACRO help to read about the macro language. Look at the example macro files (.ttl files) for examples.

Here's an example macro to get you started. Save the following text into a file named pinsearch.ttl. To start the macro, go to ControlMacro and open the pinsearch.ttl file. To pause or stop the macro, click on the MACRO window and use the Pause or End buttons.

for i 0 9999

  int2str i_text i
  strlen i_text
  len = result

  if len=1 then
    pin_text = "000"
  elseif len=2 then
    pin_text = "00"
  elseif len=3 then
    pin_text = "0"
    pin_text = ""

  strconcat pin_text i_text

  send "E"
  wait "password?"

  send pin_text
  wait "ok" "wrong"

  if result=1 goto found_it

  wait "command?"

messagebox "Didn't find password" ""

messagebox pin_text ""

You can likely accomplish this by writing an autohotkey script. Or, if you know another scripting language, write a bruteforcer in that. You may also be able to find some premade ssh bruteforcing tool somewhere that will let you define the keyspace as 4 char passwords, all digits.

share|improve this answer
I wast thinking this also. But I'm in no position to begin reading about writing a brute force script. I have found a couple of options but nothing to just simply enter 0000-9999 into a window, wait 5 seconds in between, and move to the next. –  Kelbizzle Sep 11 '10 at 20:01

I don't know if it's the right place to ask but can somebody advise me for buying a ram memory for my computer.

I have a Dell Vostro 200 with 1GB of RAM and 667MHz. (2 x 512MB)

I want to buy raise the amount of RAM but I'm confused whether to buy 1 x 2GB or 2 x 1GB

I know it's the same for the available amount of memory but is ther a difference maybe in the clock speed so that 2 x 667MHz will be better than 1 x 667MHz. or maybe accessing one single memory slot will be faster and better than accessing two slots.

Please anyone helps.

I'm getting some conflicting descriptions from Google, but it looks like that machine is about three years old. You make want to think carefully about whether you really want to spend money upgrading it - if you save that money towards a newer machine, you'll probably be better off. Upgrading old machines often costs a lot for little gain, getting you obsolete components you won't be able to re-use later. Remember - the performance depends on the whole system, not just one component - though memory is important. Basic new systems are cheap and powerful. –  Steve314 Nov 26 '10 at 1:29
For comparison, I upgraded my 2006 vintage desktop from 1GB to 3GB earlier this year. I had problems as a result of (lack of care during) the upgrade, which costed me more. I wouldn't say I regret it, but I could still buy a new PC now with 4GB RAM for not much more than twice what I spend adding 2GB of obsolete RAM to my obsolete PC. And it's easy to start sending good money after bad, trying to avoid "wasting" that earlier spending. –  Steve314 Nov 26 '10 at 1:32

The speed is how fast any operation on the RAM is clocked - not how much bandwidth is available to be shared amongst each bit of the module - so a 2GB module clocked at 667MHz should (all other things being equal) run at the same speed as a 1GB module clocked at 667.

If your machine's chipset supports dual-channel memory access, and the two memory modules are properly matched and recognised as such by the machine, then 2x1Gb may be marginally faster. While not an entirely accurate analogy, you could think of dual-channel RAM as RAID0 for memory. Most people don't really notice the difference though - the most memory bandwidth hungry things you are likely to ask the machine to do will have significant bottlenecks elsewhere, such as graphics performance or the speed or your CPU (and the CPU's cache).

Check to make sure you know what your machine can take before buying: look in the machine's manual or the databases maintained by memory sellers like Kingston. You might find it can only accept up to 1Gb per slot in which case the decision is made for you. If your machine's official spec is "max 2Gb" and it has two slots then you can pretty much guarantee it won't accept modules larger than 1Gb.

Also, be aware that you have a limited number of slots. If you plan to upgrade further later then getting the larger module now and leaving slots free might be more convenient.

We're behind some kind of Cisco routers, and have to connect via the Cisco NAC Agent. The tech support here at my university tell me that if I connect a router "the whole building will lose internet access." I find this really hard to believe, and I'd like to know: 1. Can they tell if I'm using a router and 2. How could they even tell if the router is using NAT?

This question came from our site for Information security professionals.

I don't think it was a 'threat'. I suspect their network, like many others, can't handle a second DHCP server (such as a typical router) suddenly appearing on the network. –  Rushyo Jan 17 '11 at 11:36
3 answers, with 10 votes but no one upvoted the question; people need to use the upvote more often :) +1 Upvote. In my room I am using a wireless router that is connected to the University Network via ethernet. Ethernet is connected to the WAN port. No problems so far. And I connected a Macbook and an ipod at the same time. I think the key problem you could have is if you don't use the WAN port. But if you use the WAN port you should be fine. Try it. –  Nerian Jan 19 '11 at 15:46
I doubt it will bring down the entire network, its just a warning so they can legitimately blame you for any issues if you do go against their warning and policy. No reason to run a router in a dorm, just use a dumb switch if you need more ports. –  Moab Jan 19 '11 at 16:16
Are you trying to avoid buying another device? If you have a 4-port DSL or wireless "router", understand that such devices are really switches plus routers. If you disable DHCP on the device, you can plug your school Internet connection into a LAN port, and your other devices into a LAN port, and use it as a switch. Plug nothing into the WAN port. –  ultrasawblade Apr 27 '11 at 18:31

Adding to PulpSpy's (correct) answer, it's also possible to detect routers (NAT or not) by looking at the TTL field of outgoing IP packets. End stations usually set TTL to a known number, such as 64, 254, or a few other alternatives depending on the OS. When a majority of packets are one less than this, such as 63 and so on, it indicates there was a router hop in between.

share|improve this answer
This can be circumvented by resetting the TTL on the router. –  Bogdan Maxim Jan 12 '12 at 5:36
@Bogdan Sure. Not many home routers have that capability though, and it breaks IP specs. And then of course they could deploy DPI and catch you by seeing varying HTTP User Agent headers, and a million other ways. :) –  Jakob Borg Jan 12 '12 at 13:20
add comment

Yes they probably can tell. NAT routing will reassign all the port numbers to keep which traffic originated from which computer straight. As a result your traffic will look strange and when more than one computer are connected, they will typically be on adjacent ports. It wouldn't be proof, but enough to attract attention if they were specifically screening for it.

share|improve this answer
add comment

In addition to the TTL already mentioned in the other answers, they could be using the DHCP fingerprint of your router when it'll obtain an IP from it's WAN port.

I know this because I work on the PacketFence open source NAC (a Cisco NAC competitor) and we use such tricks.

Here's the list of recognized DHCP fingerprints in PacketFence: http://packetfence.org/dhcp_fingerprints.conf

We know it's also used by other products.

share|improve this answer

They can tell if your device is a router if it broadcasts routing packets (RIP, OSPF), and by the MAC address of the external ethernet interface.

Any interface that is broadcasting it's a Cisco device (or other router vendor) will attract attention.

I find it hard to believe that the network architects at a university would leave themselves vulnerable to a TOTAL network failure, in the event that a student jacks a router into his dorm room socket. The chance that a student might try such a thing is pretty high (witness this post, for example).

The Occam's razor answer, is that the tech-support guy probably was just trying to scare you, rather than say he just didn't know.

What's more, in a peer-to-peer architecture (unlike, say, SNA where you CAN trash the whole network by pretending to be the NCP), the likelihood of something like a device conflict causing complete network failure is pretty low. It COULD BE that your router would somehow be given (or you define it yourself) the SAME ip address of one of the dorm building's own distribution hubs, but it also COULD BE that an asteroid would hit your building.

But let's assume it does happen: as long as the cisco router doesn't get rebooted, nothing happens, and your router just complains that it can't get a proper connection. Also, the cisco router would probably report the duplicate IP collision in a log somewhere (which operators or network admins would notice).

I installed emacs on my MacBook Air running Mac OS X 10.6.5 from this site http://emacsformacosx.com/. I believe this is what used to be called cocoa emacs. I dragged it into my Application folder and it works fine when I run it from there. I want to be able to run it from the Terminal. After some googling, I tried open -a /Application/Emacs.app foo.txt (foo.txt was and existing file). I got two emacs windows - one with welcome screen and one with foo.txt loaded. I tried a few applications in the /Applications directory and they did not seem to behave like this. I had installed it using my own account (an admin account) so after doing ls -l on /Application I noticed that the owner and group were different from the other entries in this folder. I recursively changed the owner and group to root and wheel, like the others, but this did not help. The only thing that looks funny now is that there that ls -l show a @ character which has something to do with extended attributes but I don't know how to check these.

Any suggestions on what to check next?

Is using the open command the only to run the program? Can I simulate what it does using a shell script?

share|improve this question

migrated from serverfault.com Feb 6 '11 at 1:41

This question came from our site for professional system and network administrators.

do you want emacs to load /in/ the Terminal window? Or do you want it to spawn window like you described? I figure, if you're in Terminal, you might just want to run emacs in Terminal, but I could be wrong. Asmus' suggestion would work if you want the former. –  Avery Chan May 19 '12 at 9:21

You misunderstand how open works: With your command open /Application/Emacs.app foo.txt you tell open to open two files, namely Emacs and the txt file, but these are two different operations: First, emacs will be started, and then foo.txt will be loaded with the default program for .txt files, which is apparently Emacs in your case.

As long as Emacs is the default for this file type, just using open foo.txt would open the file in Emacs, but if it is not the default, you would have to use open foo.txt -a /Applications/Emacs.app (the -a switch tells open what application to use) or maybe you could hand it over as a parameter with the --args option like this: open /Applications/Emacs.app --args foo.txt.

He is using the -a switch. –  Daniel Beck Feb 6 '11 at 8:03

This actually is a bit strange; for my installation (which I did with homebrew), open -a Emacs file.txt works fine… maybe you should rebuild your LaunchServices database? But anyway, you should be able to call the executable directly with

/Applications/Emacs.app/Contents/MacOS/Emacs file.txt

I am using an iMac to share a wired network connection with other devices in my house. I am using Apple's built-in sharing functionality which works very well.

I have also been using Tunnelblick as an OpenVPN client. The two technologies work great when they are not used together.

Is there a way to make Internet connection sharing and OpenVPN work together on the Mac?

The problem sounds like it may be that the VPN server is set to Compulsory Tunneling, which means that no other network connection is allowed except through the VPN.

This is a security measure for which there is no possible workaround, except via changing parameters on the server. More info here.

When Compulsory Tunneling is not set, one can use the local network through Split Tunneling.
See this article as an example of how to set it up : VPN on Mac OS X (Snow Leopard) with Split Tunneling.

Try adding manual routes for requests received through VPN.

I would do a tracert, and see if it is just bombing out somewhere along the route as I suspect.

Try this at a command prompt:

Look at the results. If it got out through a number of routers, then starts giving you a *, the best thing you can do is wait for it to resolve itself. If it persists, you can call your ISP, and ask them to contact the owners of the routers in question.

I would suggest you to do three things:

Be sure to use a recent VGA cable. Some old cables do not have the data wire, so the card can not get the EDID information from the monitor. If there is one pin missing in your VGA connector, go for a newer cable.

What graphics card do you have?

$ lspci | grep VGA

What is the EDID information reported by your monitor?

$ sudo apt-get install read-edid

^M is what you would see at the end of every line if you set the line ending to unix mode when the file was written initially in dos mode where the line endings are \r\n

So, while you see

echo $item >> $outfile

unix sees:

echo $item >> $outfile^M

:set ff=unix

to remove the ^M

For some silly reason I assumed you're using vim. Maybe because it's the only editor that I've seen show the \r as ^M. Anyway, do what Dennis Williamson said, use the dos2unix tool.

If you are running Windows those tools are called the Performance Monitor and Resource Monitor. For Linux, top/htop can give you a lot of good info. However, these tools will not draw conclusions for you. You need to look at several things
- CPU use and processor queue length - Hard Page faults (page faults that need to be read from swapfile/disk - disk queue length

Queue lengths should not be sustained above 2 for nay resource (Multiply that by #cores for CPU)

Small numbers of page faults are OK.

We have an office where multiple people use Dropbox to share files, and sometimes several users are on the same folder. When an external party adds a large file into one of these shared folders, all the Dropbox apps try to download the file simultaneously and it cripples the LAN. My thoughts:

  1. Slow down the download bandwidth for all of everyone's downloads to the point where the problem doesn't exist (but this seems like hitting a nut with a sledgehammer, and disadvantages other downloads)
  2. Install QoS on the network (I think this might be the best solution?)

In an ideal world, I'd like to see one account download it, then use the LAN share feature to get it to everyone else.

What solutions might allow speedy Dropbox downloads of the same file to multiple sharing users, and not kill the LAN?

share|improve this question

There is an open feature request at the Dropbox forum for a sync scheduler. But, that feature doesn't exist in Dropbox yet... so as it stands, if it is running and has a net connection, it will sync.

Without installing QoS (like a router running DD-WRT, etc) into your network, one solution is that the users all Pause Syncing (from the Dropbox menu), and then manually synchronize when they resume. This would involve communicating with each other, with one user never pausing so they can notify the rest when there is an update. This one user could also just notify only one of the paused users, who in turn would notify the next user, etc. Sure. Kind of a pain in the buttocks, but it doesn't involve changing your network topography.

You could investigate whether or not using Google Drive would be a viable replacement, and if it would also cause the same issue.

In that ideal world of yours... you just don't have everyone connecting to Dropbox. You only have one. You then share that directory on your network, and have everyone else access the shared directory.

1 Answer

I believe your Beetel 440txi router has a built-in DSL modem for its WAN port, and doesn't provide an Ethernet WAN port, is that correct?

If so, then you can't hook its (DSL) WAN port to your other DSL router's (Ethernet) LAN port, because DSL and Ethernet are two different technologies, even though their connectors may look similar in some countries (RJ11 for a telephone/DSL line, wider RJ45 for Ethernet cable).

Since you already have another DSL router plugged into your DSL-enabled telephone line, let that router be your PPPoE client, NAT gateway, and DHCP server for your home network. If you want to add the Beetel 440txi to the network to provide more Ethernet ports or additional Wi-Fi coverage, then turn off the 440txi's PPPoE, NAT, and DHCP services, and use and Ethernet cable to plug one of the 440txi's Ethernet LAN ports to one of the Ethernet LAN ports on the other DSL router.

I am trying to convert a couple of short videos to AVI (XviD) using AVIDemux.

I tried using all three of the AVI Muxer Output Format options, but none worked.

The version I was using (2.6.0 beta) seems to have a bug that produces non-standard AVI containers.

Updating to the latest nightly has fixed the bug and produces AVI files that can be read by Windows Explorer.

One caveat though, my tests have found that sometimes AVIs produced even with the nightly do not show up correctly in Windows Explorer unless you specifically make a selection; simply leaving the selection absent will indeed select the whole video, but then the resulting video is unreadable by Explorer (this is not always the case and seems to depend on the source video, but my tests were consistent, so always making a selection, even if it’s the whole video is a good idea).

This question came from our site for professional and enthusiast programmers.

An intrinsic property of reducing the size is losing information. you cannot get it back again. –  Keith Nov 10 '12 at 0:06
Why not keep the original file around? No need to resize it back and no quality lost. –  Hennes Nov 10 '12 at 0:55
Hennes: I want a smaller size (dimension) for an image file. But when I reduce the size using resize, I lose resolution and the image does not look good. I was wondering how I could avoid that so I posed the resize 50%-resize back 200% question. –  Excalibur Nov 10 '12 at 1:24

"If it was one image, I can use tools like gimp" - How can you do this even in GIMP? If you resize to 50% of the original dimension, you've discarded data. Blowing/scaling the raster image back up to the original size only duplicates pixels, it doesn't magically bring lost data back. PNG being a lossless format is not going to help in this case.

The only possible way you can do this AFAIK is to use a vector image format that ImageMagick supports, such as MVG or SVG.

Note: You can always try converting the raster images to vector first before resizing, but I doubt the results will be all that satisfactory.

Thanks Karan for your reply. You are correct that its not simple even in GIMP. I can go a round about way to accomplish this: I set print size to half which automatically doubles the resolution, and then print it to a pdf. Getting the image from the pdf is again not straightforward but it is possible. An easier solution which is generally what I do is to import the image in inkscape, scale it and export the image. This is along the lines of your comment that it has to be converted to svg to be able to scale it. Anyway, I am surprised that there is no tool that resizes but does not lose data. –  Excalibur Nov 10 '12 at 1:19

Good Afternoon,

I have a number of desktop themes on my Windows 7 PC that change from one picture to the next after a certain time interval.

Is it possible to create my own desktop wallpaper theme, with my own pictures that are in JPEG format ?

Yes, you can save your desktop theme in Windows 7.

Set it up however you want it to be - the various pictures in the desktop slideshow, the timing of the transitions, etc. You will see in the "Personalization" window a theme called "Unsaved Theme". Right-click and click "Save As". Now you can save your theme for later use!

How do I create the "theme" in the first place ? –  Simon Nov 26 '12 at 17:10
@Simon - I think maybe studiohack made the assumption that you already know how to get to the personalization settings (your question could easily read as "What can I do with this tool?" not "Does this tool exist?". One thing to keep in mind with Windows 7 is that the Start Menu search is your friend - try looking for 'wallpaper' or 'theme'. –  Shinrai Nov 26 '12 at 17:13
@Simon set it up however you want - i.e. add the pictures you want to your desktop slideshow, tweak the timings, and then save it as it is. –  studiohack Nov 26 '12 at 17:14
@Shinrai - I know how to get to personalization settings, right click desktop, and there are many themes that I have downloaded from Windows Gallery. I have a folder containing many jpeg images (say 15), and I want to make those appear as a theme –  Simon Nov 26 '12 at 17:16
@studiohack - Thankyou, I just did exactly what you said and it worked :) –  Simon Nov 26 '12 at 17:26

I have a HP DV6 laptop with ATI Radeon HD 6490M GPU. It came with Windows 7 preinstalled. I recently installed Windows 8 Pro onto it. The GPU(s) shown are Intel HD 3000 and ATI Radeon HD 7400 Series

How is this possible, Windows 8 detects a wrong GPU and installs the Driver also. The GPU shows a warning sign (error). I am not able to use the GPU, catalyst also doesn't recognize this GPU.

The GPU works perfect on Windows 7. I tried installing Win 7 drivers but it doesn't help much, the correct GPU is detected but it still doesn't work.

Any help is appreciated. Also I feel like no Windows 8 64bit Driver is available for this GPU.

HP provides a guide how to enable the GPU:

  1. Install the HP Software Framework as found here.

  2. Next, uninstall all ATI/AMD software through Programs and Features.

  3. Go to www.hp.com and select Support and Drivers at the top.

  4. Select Software and Driver downloads and enter your product model or product number.

  5. Select the most recent operating system matching your installation of Windows 8's bit architecture. For example, Windows 7 64bit for Windows 8 64bit.

  6. Download the ATI graphics card driver.

  7. Run the file once it is finished downloading.

  8. Let the extraction process finish, but cancel the installation when prompted to continue it after the extraction. Take note of where this is extracted to. By default, this should be c:\swsetup\.

  9. Here, there should be a setup.exe for installing the ATI driver. Right-click this and select troubleshoot compatibility.

  10. Follow the compatibility troulbeshooter and select the suggested fixes. On one screen, there will be a test program button. Click this to begin the installation.

  11. Follow the installation and it should finish successfully.

  12. Once finished, right-click the desktop to verify the configure switchable graphics option is listed.

Try it, maybe it works for you, too.
