Ask Slashdot: Where Can You Get a Good 3-Button Mouse Today?

kriston Kensington Expert Mouse (396 comments)

I switched to the Kensington Expert Mouse trackball when it first came out many years ago. All versions have four buttons. The newer versions have added a scroll ring around the trackball. As a result, I have been able to avoid RSIs. The added benefit is that users of these trackballs have enhanced functionality in day-to-day operations, from programming, to browsing, to graphics work, and gaming.

Since you mentioned physical discomfort with a dangling ring finger I must stress that you try out the Kensington Expert Mouse (can be bought new as cheap as $60). The ring finger rests on the right button or the upper-right button depending on your preference.

Inside Cryptowall 2.0 Ransomware

kriston Re:So how are these spread? (181 comments)

In a case I was recently troubleshooting, the vector was an advertisement popup that asked the user to click to download and install an Adobe Flash Player update.

The user downloads it and runs it. Then it runs quietly in the background with the same privileges as the current user.

I feel the need to reiterate here that Cryptowall does NOT require privilege escalation. If you happen to be a local administrator it will ask for it so it is able to delete shadow copies and Restore Points, but it does not need any extra privileges to encrypt your data and thus accomplish most of its aims.

Tips For Securing Your Secure Shell

kriston Re:RC4, how weak is it? (148 comments)

RC4 isn't "broken." It is only bad when used incorrectly to store static data, like some older electronic wallet software had done. When used as a stream cipher it's very efficient and very, very secure.

Even the default re-keying interval is sufficient but if you are really skeptical you can shorten it and have it re-key based on time, quantity of data transmitted, or both.

myOpenID to shut down in February

kriston kriston writes  |  about a year ago

kriston (7886) writes "This is an email sent to myOpenID.com users this afternoon.


I wanted to reach out personally to let you know that we have made the decision to end of life the myOpenID service. myOpenID will be turned off on February 1, 2014.

In 2006 Janrain created myOpenID to fulfill our vision to make registration and login easier on the web for people. Since that time, social networks and email providers such as Facebook, Google, Twitter, LinkedIn and Yahoo! have embraced open identity standards. And now, billions of people who have created accounts with these services can use their identities to easily register and login to sites across the web in the way myOpenID was intended.

By 2009 it had become obvious that the vast majority of consumers would prefer to utilize an existing identity from a recognized provider rather than create their own myOpenID account. As a result, our business focus changed to address this desire, and we introduced social login technology. While the technology is slightly different from where we were in 2006, I’m confident that we are still delivering on our initial promise – that people should take control of their online identity and are empowered to carry those identities with them as they navigate the web.

For those of you who still actively use myOpenID, I can understand your disappointment to hear this news and apologize if this causes you any inconvenience. To reduce this inconvenience, we are delaying the end of life of the service until February 1, 2014 to give you time to begin using other identities on those sites where you use myOpenID today.

Speaking on behalf of Janrain, I truly appreciate your past support of myOpenID.

Redux: Optimize performance of EC2 EBS volumes and Amazon WorkSpaces

kriston kriston writes  |  about 6 months ago

This is an update to my previous Journal article "Optimize performance of EC2 EBS volumes and Amazon WorkSpaces." Along with writing each unused sector, Amazon also recommends reading from each sector. To do this we can use the Windows version of the "dd" command available at http://www.chrysocome.net/dd.

1) Find the name of your drive:
        wmic diskdrive get deviceid

2) Choose one. It will look something like \\.\PHYSICALDRIVE0.

3) Type this command carefully:
        dd if=\\.\PHYSICALDRIVE0 of=/dev/null bs=1M --progress --size

4) When completed, repeat step 3 on \\.\PHYSICALDRIVE1 and any other volume you have on your instance. For example, Amazon WorkSpaces will have a \\.\PHYSICALDRIVE0 for drive C: and \\.\PHYSICALDRIVE1 for drive D:.

These instructions are from this article: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-prewarm.html.


Optimize performance of EC2 EBS volumes and Amazon WorkSpaces

kriston kriston writes  |  about 8 months ago

Amazon EC2 and Amazon WorkSpaces are very handy. Unfortunately, the first time you bring up any new instance the performance starts slow and improves over time. This is apparent when creating any new EC2 instance on EBS, when creating a new EBS volume from a snapshot. This includes creating an AMI and also copying volumes to other Availability Zones.

The culprit is Thin Provisioning. The EBS volume is only allocated physical space when it's needed. This is fine for Amazon but not so fine for your performance. There is an easy to to remove this millstone from around the system's neck but it will take some time and may cause network charges to do so. It's well worth it if you plan to use the system for regular work, and especially if you use Amazon WorkSpaces as one of your daily desktop environments.

My examples use the "dd" command in Cygwin or Linux. In Windows you can use Cygwin or search for the various dd.exe commands available on the internet.

On a brand-new Amazon WorkSpaces instance, see how much space is free on your "C:" and "D:" drives. On a regular EC2 instance, see how much free space is on all your drives (you will know this already). Write these values down.

Start a shell (or Cywgin shell as Administrator) and do the following. Note that if you're using dd.exe without Cygwin it's up to you to figure out what the "if" parameter would be.

dd if=/dev/zero of=./datafile-40gig.dat bs=10M count=4096
Check how much data is free:
df -kh .
Then repeat the "dd" command again with new values to fill the remaining data.

In this particular example my volume had a little over 40 gigabytes free so I'm creating a file of 40 gigabytes in size. The block size is kept at 10 megabytes. You can fine-tune this but in my experience nearly any values that add up to 40 gigabytes takes the same amount of time to complete.

Of course, when these complete, don't forget to delete the files.

That's it. You don't need to reboot. Thin provisioning has been defeated and you can enjoy better performance on your EC2 and Amazon WorkSpaces instances.

Note: In Windows you could theoretically create a new paging file of 40 gigabytes but I have not been able to prove that Windows actually writes 40 gigabytes to disk or just allocates the 40 gigabyte space as in-use. I suspect the latter, in which case it does nothing to improve performance.

This process can be used on any other storage architecture, virtual machine or not, that is configured to use Thin Provisioning. If you suspect shenanigans are happening in which the storage system knows you're just writing zeroes and defeats you, you can use /dev/random to counteract and force physical alocation. It will take far longer to write the data file, however.


Using Amazon WorkSpaces from Linux using rdesktop

kriston kriston writes  |  about 8 months ago

The Amazon WorkSpaces product is an interesting and affordable desktop-as-a-service from Amazon. For a flat, monthly rate, you get the equivalent performance of an m3.medium EC2 instance for far less cost but also with somewhat less configuration flexibility. The compelling feature of Amazon WorkSpaces is supposed to be close integration with your own Active Directory with Group Policies. For me, the more compelling feature is the high-performance, proprietary Teradici PCoIP protocol used for remote access instead of the traditional Microsoft Remote Desktop Connection protocol. The PCoIP protocol is much more efficient and faster than RDP but, unfortunately, the Amazon WorkSpaces client is not available for Linux or ChromeOS. With some work you can get access to your Amazon WorkSpace using the conventional Microsoft Remote Desktop Connection or even VNC.

Here is how you can use regular "rdesktop" on Linux and Macintosh, or Microsoft Remote Desktop Connection on Windows to connect to Amazon WorkSpaces. It won't be as fast or as nice as the Amazon WorkSpaces client but it works as acceptably as any RDP connection.

First, open your Amazon WorkSpace and ensure that Windows Firewall has opened TCP port 3389.

Then open a cmd prompt and type ipconfig. Essentially, you are finding out what private IP your WorkSpace is using. Write it down.

In the EC2 Console, poke around to find the public interface associated with that private IP address you wrote down and write down its public IP address.

Again, in your EC2 Console, find the Security Group associated with the public interface you found in the previous step.

Edit the Security Group associated with the public interface. Create a rule that allows TCP port 3389.

Now you can log in using "rdesktop" on Linux or Remote Desktop Connection on Windows. Just use the IP address for your WorkSpace that you found in your EC2 console. If you want to be more elegant, register your WorkSpace's public IP in DNS using Amazon Route 53 or dyndns.org.

You're going to quickly find that Remote Desktop Connection isn't as fast or nearly as responsive as the official Amazon WorkSpaces client. This is because Amazon WorkSpaces uses Teradici PCoIP, a proprietary product specifically designed for high-performance remote desktops. This protocol is much more efficient and faster than Microsoft Remote Desktop "RDP" protocol, but with these steps you can still enjoy access to your Amazon WorkSpaces without being limited to using machines that can run the proprietary WorkSpaces client.

Dell XPS 12 Ultrabook problems

kriston kriston writes  |  about a year ago

The Dell XPS 12 Ultrabook has a number of problems that require too much attention. Perhaps that's why I bought one new today for over $400 off list price. This Ultrabook has a 12.5" 1920x1080 screen, touch screen, Intel Core i5, 4 gigs of memory, 128 GB SSD, and has a nifty screen flipping feature so you can use it like a tablet.

Here are a few problems so far.

The keyboard is bad and the keys stick up unevenly. Normally this isn't a problem but the white LED backlighting points out to you which keys are jutting out. It's okay to type on but I prefer to flip it into tablet mode and plugging in a tenkeyless mechanical keyboard.

More importantly, the touch screen can stop working. What happens is the two I2C HID Devices under Human Interface Devices are disabled by Windows because it "detected a problem." This happens randomly but most often when coming back from sleep. I got used to the touch screen, especially in tablet mode, so I'm not sure I want this feature disabled. Simply doing 'Scan for hardware changes" in the "Action" window will re-enable them but they will eventually stop working again. So updating the BIOS should fix this. The BIOS update from Dell from A03 to A04 updates the BIOS, another Intel firmware (likely the touchpad's firmware since it's an Intel device), and a third firmware, and reboots. Following this, updating the touchpad drivers from Dell should do the trick and I will be watching this for success.

Finally, updating to Windows 8.1 complains that my user is not an Administrator. Well, this is, of course, incorrect. What I did to fix this is to remove the Windows Update 2871389 from the system, reboot (takes a long time), run Windows Update and install updates again, reboot (again takes a long time), and then go back to the App Store to download it again. Finally, now I'm waiting for over three gigabytes to download.

The screen is beautiful and it's too bad Dell and Intel didn't test this Ultrabook enough. They must have lost a ton of money on this model. My local store had around 25 new in stock at fire-sale clearance prices. You can't get a 12.5" 1920x1080 Ultrabook at anything near this price, let alone a Core i5 with 4 gigabytes of memory, 128 GB SSD, and a "carbon fiber" case, whatever that means. Just make sure you have the patience and problem-solving skills to work out the problems.

Windows Experience Index details (before Windows 8.1):
Processor 6.9
Memory 5.9 (bummer)
Graphics 5.7 (Flunky Intel graphics)
Gaming Graphics 6.5 (Flunky Intel graphics)
Disk 8.1 (Superb!!).

A great value for a new Ultrabook over $400 off the list price. Too bad for Dell's profits on this troublesome Ultrabook.

Scanning documents and cleaning them up

kriston kriston writes  |  more than 3 years ago

Years ago I got into the habit of taking handwritten notes and scanning them into the computer. I then have a digital record and no paper lying around to get lost, stolen, or cluttered.

A problem has arisen with this recently. Late-model multi-function copiers like the Xerox ColorQube scan at such a high resolution and sensitivity that they capture not just the handwritten notes but the texture of the paper. This is extremely annoying because all I want is the writing, of course, and even the "Remove Background" feature of the Xerox ColorQube just doesn't.

So, for the time being, here is a cheap way to remove backgrounds. Load the scanned document into your favorite editor and reduce it to sixteen color palette.

For example, in Paint Shop Pro 4, my favorite for quick-and-dirty fixes, select Colors...Decrease Color Depth...16 Colors and select "Palette Windows'" then "Nearest color" and finally "OK." This magically removes the background noise and so far it has worked on nearly everything I scan.

Be sure you do this after scaling down your image. PSP 4 calls this "Resample" which, by the way, is the only correct way to resize an image in PSP 4.


Solving Google Earth's bad performance

kriston kriston writes  |  more than 3 years ago

Forget CentOS, who are taking too long with 6.x. Amazon AWS with Red Hat Linux 6.1 for $0.085/hour for t1.small is excellent and $0.02/hour for t1.micro is even more excellent for high-availability services.

For file backup services, the S3 reduced-redundancy storage for $0.093/GB is a steal, but make sure you convert your storage buckets to RRS. The Windows Home Server plugin does not set RRS so use an Amazon EC2 instance to run convert_to_rrs.py and quickly convert your bucket to RRS for big savings. The AWS console won't work on huge buckets, nor do the popular Windows-based S3 tools. This might cancel out some of the savings.


How to kick-start Windows 7 updates

kriston kriston writes  |  about 4 years ago

Do you want to kick-start Windows 7 updates for a computer you've built or set up for someone else? This is what I do and it mitigates the threats to newly-installed machines. It installs certain libraries and other dependencies that trigger Windows Update to give you the latest and greatest. You can let the user do the Service Pack updates at a later time. In this situation we are bootstrapping the update process for most of the important libraries and software you care about without buying Microsoft Office and installing the most important updates before you leave the user to his own devices.

Download and install the following software in this order on another PC and put them on a USB drive.
Do not connect your new computer to the internet yet.
Run these installers in this order. Nothing should ask you to reboot, but if it does, let it reboot and continue with the next one.

Microsoft Word Viewer 2003 (the latest is Word 2003).
Microsoft Visio Viewer
Microsoft PowerPoint Viewer 2007
Microsoft PowerPoint Viewer 2007 SP1 Update
Microsoft Excel Viewer 2007
Microsoft File Format Converters
Microsoft DirectX Redist
Microsoft .NET 3.5 SP1 (Windows Vista and XP Only, x86 and x64 are in the same download)
Microsoft .NET 4.0 Full (x86 and x64 are in the same download)
Microsoft Security Essentials

Restart your computer.
Go to the Windows Update control panel, click "Check for updates," and then install all of the Required and Optional ones.
After you're done with all this, go to the Windows Update control panel and ask it to install "for all Microsoft products". This is somewhat more difficult to find.
Go to Windows Update and hit "Check for updates" again and install everything.

Note that Microsoft .NET 3.5 SP1 includes .NET 2.x and 1.x inside it. Windows 7 has 3.5 SP1 built in already. Windows Vista may or may not depending how old it is.

Review of ABS mechanical keyboard

kriston kriston writes  |  more than 4 years ago

[Reposted from Newegg because I'm proud of my review.]

Blurb: "Great feel and nice loud sound, but not a Model M clone"

Pros: Loud, ringing reverberation is just like keyboards of old PC clones not made by IBM (see Cons).
The keyboard is only a little larger than the keys take up. This is a major bonus if you like small keyboards but don't want to compromise on keys.
FULL SIZE caps lock key for Unix people who remap CTRL to caps lock. This is rather rare on any keyboard (and I am still searching for a Model M clone with full-sized caps lock either).
The keyboard is nice and heavy as nature intended, with amazing, grippy rubber feet (and really good rubber on the risers, too, also rare).
Stiff, solid, and a very tasteful matte black finish that isn't painted on (the plastic is black).

Cons: The case reverberates a bit with a ring. Your table may amplify or muffle it. I don't happen to care but you might.
This is not a Lexmark Model M keyboard clone and does not pretend to be. The reviewers who think this is a Model M are confusing this with another type of old-school "clicky" keyboard.

Other Thoughts: This type of keyboard is not the same as a Model M. The clicking noise comes from the keys landing, not from the (very faint) click in the key mechanisms themselves. However, the click happens at the moment of keystroke actuation which gives this a nice touch. I didn't feel any of the "halfway down" actuation some other reviewers claimed.

This keyboard is an excellent a clone of those "other" clicky keyboards that came with Compaq IBM PC clones in the late 1980s and early 1990s. I have about twenty real IBM/Lexmark Model M keyboards in various states of repair. Those boards click loudly as the key is struck and also when the key hits the back plate. This one only really clicks when it hits the back plate. If you had a PC clone in the late 1980s or early 1990s you know this feel. I think some people call it the "Cherry" feel.
It's not better or worse than the Lexmark Model M; it is just different.


Cherrypal Africa Windows review

kriston kriston writes  |  more than 4 years ago

The unit is a very small and light, slightly customized version of those $100 laptops that have been spreading across Asia for the past year or so. The model I ordered runs Windows CE 6.0 and a suite of custom installed programs like various media players and document viewers. The Youtube application does not work but the rest work fine. The machine is rather slow but it browses the web just fine. The word processor is also good. Some applications are formatted for Pocket PC (the menu bar is on the bottom instead of the top) but Windows CE users are used to this. A benchmark I ran says 200 MHz but I believe that speed is actually due to power management which is always adjusting the CPU speed based on your usage of the unit.

My unit came with some nasty glue that I had to clean off, presumably from stickers that were removed from the original manufacturer. The Cherrypal brand stickers are coming off, too.

I had to order this thing four different times. The credit card processor changed each time, too, but no money was stolen from me. The Cherrypal people say the delays and strange circumstances were due to hacking attempts but my own observations make me speculate that too many customers complained to the credit card ordering processor which caused Cherrypal's account to be terminated for undelivered goods. I persisted through four different ordering processors since December of 2009 and eventually got my unit in late March 2010.

When you order the Cherrypal Africa you are not guaranteed any particular processor type, memory, or screen size, just the minimum specs. This means that your processor can be ARM, MIPS, some x86 variant, or maybe even a PowerPC. Most people seem to have gotten what I have, which is a "VIA" ARM-VT8500 and I'm not really sure if that's the real "VIA" from Taiwan. It also has 128 meg of ram, WiFi, and 2 gigabytes of NAND flash.

In conclusion, I expected what I had received, which is an extremely basic laptop. One thing I didn't expect though was that the "Windows XP" spec was changed to just "Windows" when I had originally ordered it. If I had realized that it is Windows CE I would have ordered the Linux version instead.


Install Go-OO version of OpenOffice on Fedora

kriston kriston writes  |  about 5 years ago

OpenOffice, the free desktop office application suite, is almost totally compatible with Microsoft Office. It does not support *.docx files and other proprietary (non-free) elements that are needed to share documents with users of Microsoft Office. Novell has solved this with their own version of OpenOffice but it is only for Windows and SuSE Linux. For Fedora users the Go-OO version can be used. Go-OO is the special version of OpenOffice with the non-free elements which Novell's version is also derived from. It should be noted that Fedora's version of OpenOffice is also Go-OO with the non-free portions stripped out.

The challenge is to replace the OpenOffice that cannot be removed from Fedora with this new, enhanced Go-OO version. It's not easy because OpenOffice is a core desktop application and Fedora forbids its removal without removing about 300 other packages that make up the desktop operating system. We're going to force an installation of Go-OO on my Fedora system, uninstall the "required" OpenOffice, and then force another installation of Go-OO on top of that to get things cleaned up.

Go to http:/www.go-oo.org/ and read the documentation.

Run Go-OO's downloader script in its own directory:
        mkdir GO-OO ; cd GO-OO
        wget http://go-oo.org/download/download-go-oo.py
        chmod a+rx ./download-go-oo.py ./download-go-oo.py

Forcibly install everything it downloaded:
        sudo rpm --install --force *.rpm

Remove the original OpenOffice packages:
        sudo rpm --erase openoffice.org-math-core openoffice.org-presenter-screen openoffice.org-opensymbol-fonts openoffice.org-core openoffice.org-math openoffice.org-brand openoffice.org-calc-core openoffice.org-impress-core openoffice.org-writer-core openoffice.org-graphicfilter openoffice.org-draw-core openoffice.org-langpack-en openoffice.org-xsltfilter openoffice.org-impress openoffice.org-writer openoffice.org-calc openoffice.org-extendedPDF

Install Go-OO forcibly again:
        sudo rpm --install --force *.rpm

Now it's all set. I can read and write *.docx and *.xlsx files in Fedora. It's also much faster than Fedora's OpenOffice.


HP MediaSmart Windows Home Server update notes

kriston kriston writes  |  more than 5 years ago

I'm not sure why, but we bought another HP MediaSmart Windows Home Server with the intention of gifting the old one to someone else. This version is really different. Not only is the server two gigabytes of memory and uses a 64-bit CeLeron processor, it also has a large number of features that were not present in the refurbished Sempron 512-megabyte HP MediaSmart server. I'm not really sure why but this newer model has Amazon S3 backup service and a huge number of new features that aren't present on the Sempron-based version. We updated the server software on both models but only the Intel CeLeron model has the new features.

If you're going to try out Windows Home Server to automatically and effortlessly backup your Windows machines, get a non-refurbished Intel-based HP MediaSmart server. All of these new features are in the HP MediaSmart software and not WHS itself. I'm not sure why HP did this but it's eye-opening.

I'm going to try to install the Amazon S3 and other software add-ins to our older, refurbished model by doing a "factory restore" from the Server Recovery Disc that came with the non-refurbished model and see if these awesome features get installed on the older server.

Very interesting difference. It might be that the newer one has two gigabytes of memory and the other one only has 512 megabytes. It's possible the features are dependent on the memory specifications of the server, but I doubt it.


Windows Home Server the Sleeper Killer App

kriston kriston writes  |  more than 5 years ago

Windows Home Server has a really neat feature. Install the Windows Home Server Connector and configure it to back up your computer. In a day or so take the hard drive out of the computer and throw it into a lake. Get a new blank hard drive. Boot the computer from the Windows Home Server PC Recover disc. YOUR COMPUTER COMES BACK.

This is the killer sleeper Windows app of the new century!!


Flashblock getting fooled

kriston kriston writes  |  more than 5 years ago

The Mozilla Flashblock plugin is getting fooled by advertisements on some sites like urbandictionary.com which use a countermeasure (seems to be iframe abuse). Installation of version 1.5.11a2 from the special link http://flashblock.mozdev.org/installation1.html solves the problem for now.


Why Cox Cable's video service is stupid

kriston kriston writes  |  more than 5 years ago

Here's the stupid thing about Cox Cable Television in the Northern VA area.

Technicians are going crazy yanking old cable off the telephone poles to install multi-wavelength fiber and switched-video-compatible boxes because they ran out of bandwidth to compete with all the HD channels that the other services, like FiOS and satellite, offer.

The stupid thing is that FiOS has the same 1 gigahertz video capacity that cable does (not including Video-on-Demand which is served by Internet on FiOS and through hidden video channels by Cox). Likewise, FiOS has twice the SD channels and HD channels without the need for switched-video to solve a perceived bandwidth problem.

This doesn't make sense. I did some digging. For now I still use cable internet so I scanned the Cox Cable signal on my HDTV and found out that nearly all of Cox Cable's SD channels are still analog. This means that most of Cox Cable's 1 gigahertz of bandwidth is consumed by analog channels at 6 MHz per channel, even though you can fit more than 10 digital channels in one analog channel if they were to use digital instead.

Why is Cox Cable spending so much money installing switched-video if all this bandwidth is available?
Why isn't Cox Cable using digital for their SD channels?

Apparently the bandwidth required for Video-on-Demand is the business reason for the switched-video upgrade, but switched-video is not just for VoD. It is also used on non-VoD channels because of a system-wide bandwidth shortage on Cox Cable. This means if nobody in a neighborhood watches Food Network HD, it gets turned off until someone tunes it in again.

The cause of the problem is that Cox Cable is still using 6-MHz-per-channel analog for most SD channels.


Godwin's Law for Software Engineering

kriston kriston writes  |  more than 6 years ago

In professional Software Engineering circles we debate topics with real-world applications.
Sometimes, the debate must be aborted when a participant quotes one of the following so-called pundits. Most of them are academics or failed dot-com company founders.
The key point here is that "professional Software Engineers," referring to people who make a living actually accomplishing real work on real systems.

Here is the list of Godwin's Law violations.
Quoting them makes you forfeit your side of the debate:

Joel "On Software" Spolski
Daniel "I always wear black" Bernstein
Randal "I hacked into Intel and all I got was this felony conviction" Schwartz
