One Linux-based HPC vendor bought out another Linux-based HPC vendor, this will not really effect Linux on HPC. All of the Top 10 of the TOP500 use Linux in one way or another. The Blue Genes have SLES on the service nodes and CNK on the compute nodes. The SGI is SLES with add-ons. The HPs are Linux clusters. The Crays are SLES on the service nodes and either Catamount or Linux on the computes.
Linux is very pervasive in HPC and becoming more so. Since I know a little something about Cray, the newest vector and scalar lines both use Cray Linux Environment (CLE) formerly called Compute Node Linux (CNL). Cray's CNL was released in second half of 2007 and already over half of the Cray processors in production are running CLE on the computes instead of Catamount, the very lean, proprietary compute node OS.
Why does everyone assume digital means better? In my experience "fuzziness" with cable is usually cause by horrible wiring (no grounding, split many times, etc.) within a house/apartment, not an inherently bad signal. Cable companies still have a significant portion of their customers using the analog signals because they either don't have digital cable or have more than one TV but don't want to have multiple cable boxes. Thus, the analog signals tend to be relatively clean. The purely digital channels, on the other hand, look to be encoded at such a low bitrate that one can easily see macroblocks continuously.
You have a really bad encoder if it can't look good at 7mbps (4.7 GB * 1024 GB/MB * 8Mb/MB) / 5432 seconds. Standard DVDs are usually around 5mbps and Superbit are around 9mbps. Is it doing all I-frame encoding?
If you are looking for best encoder for the money, I'd say TMPGEnc 12j. Canopus is also a good choice if money isn't an issue.
Being a poor high school DIYer, building my own computer was the only way I could upgrade to "modern" hardware from my then-ancient Apple IIe. I sure as heck couldn't afford Windows 3.1 nor did I have any experience with it. These Linux floppies were supposed to be a lot like SunOS which I had used on my high school's only non-Mac computer.
So sometime in the '93-94 schoolyear, I switched from apple basic to linux for the hardware support.
Build a 3D imager. Gregg Favalora, the founder of Actuality Systems, did just this as a precursor to his company's 3D imaging systems. It consisted of lasers from laser pointers, a spinning plane, and a microprocessor. The array of lasers would light momentarily to create voxels, 3D pixels, on the plane. Add some well-crafted software and you have 3D monochromatic display. I can't seem to find a image of this on the web, but I can assure you the picture of Homer Simpson's head was unmistakeable.
Note: I am sure it was nowhere near as simple as I have explained, but I believe the concept is correct.
Back in '98 the instructions Yale freshman received for checking email was to login to one of the mail servers (ssh or telnet) and run pine.
At my current company, our system administrator enforces a no IE policy. Too much of his time was spent applying security patches. For a short time he strictly enforced this via our http proxy not allowing IE, but our CEO *needed* to be able to use IE for some site that was laiden with MS specific MSHTML.
I had the same problem (Linksys AP, Linksys PCMCIA, and Ambicom PCMCIA) where tilting my laptop made my reception noticably better. Moving the AP (higher) was the biggest no cost boost. Changing the antennae config helped, too. Getting better antennae, however, is the way to go (at least in my house). I got some off an old Proxim rangelan base station and now I get great reception all over the house. These may not have been the originals, as the AP was donated by my old CS department for Robocup 98.
I don't know if this is only for business customers, but I know they do have this as an option. Instead of the normal two cable modem/any linksys product-sized boxes, this configuration has three.
The transmitter and receiver (model# ITU-R1 and IRU-T3, respectively) actually have the DirecPC logo on the front and either the word "transmitter" or "receiver." Both of these have an antenna connector and a data connector (DB-25 or so). In addition the transmitter has a USB port and an AT-keyboard-connector-looking power input. The third box (model# DW4-G1) is labeled "gateway" and has the DirecWay logo. The back has a USB port that is connected to the transmitter, a similar power input that is piggy-backed from the transmitter (looks kludgey), and four ethernet ports.
Functionally, this third box seems like those "cable/DSL routers" except you connect to the outside via USB instead of regular ethernet.
This one came out of necessity after a North Dakota sleet storm. The only thing I had in the car the had a hard edge was an AOL CD. It worked much better after breaking it in two pieces to get a straight edge.
The only reason I had the disk is that the case work as replacement DVD case when the plastic center-hole prongs break. Just pull out the AOL sheet out of the outer clear plasic, clean off the sticker (easier said than done), and replace with DVDs jacket artwork.
If if you have a university in your area, contact both their compsci and IT departments. Sometimes they are not that pretty, but they just sit in my basement and a closet of my computer room anyway.
The point wasn't that someone could commit identity thief; the point was that since Princeton would readily have access to this infomation for the students that also applied to Princeton. They could have been using this as a method to determine whether the candidate had applied to Yale.
I was hired to develop linux drivers for my company's cards (multichannel MPEG2/4 playback). I was hoping to open source my work. It seems that a few years before we had released the source to a partner company who, approximately one year later, were building almost identical cards released with our driver. It seems that in our market the abilities we have put into the driver is what differentiates us from our competition. Sure if we hadn't been such a small company at the time we could have hired lawyers to draw up viable NDAs but at the time we didn't have lots of extra money to spend on frivilous things like lawyers.
While I have been an avid reader of Slashdot for about 3 years and Linux user for 6 years, I think the continous Linux is better/MS is better and MS is the devil/MS isn't so bad arguments are rather pointless here. Most people who read/. are already pretty opinionated on the subject and for the most part Linux/BSD biased. If you think your comments are going to change readers' minds you are sorely mistaken. Unless you are a linux zealot and enjoy the big circle jerk you are probably wasting keystrokes by bringing up the same arguments we have all heard a million times.
If you really want your comments to count bring them to the people in your company that decide what software the company buys. If the person/group of people already seem to have their minds made up, show them why your choice is better. I realize that this seems only to be a call to the Open Sorcerers, but I have seen it work the other way, too.
If you are on the West Coast make a trip to your nearest Fry's, They have patch panels, computer parts, aisles of cables, almost anything you would like. Why they don't expand to every city with a strong geek cluster is beyond me. Some friends and I made our Disneyland or Disney World decision based on the fact that Cali has Fry's.
This started out as Gregg's senior project. It was a bit more crude and was monochromatic then, but it did run almost constantly for my senior year ('98) looping through a few different images including a nice 3D Homer Simpson head. Putting aside the tech aspects of this story for a second, I would just like to comment on how nice it is to see an engineer bringing his own idea to fruition in his own company.
According to MIT's Graduate Admissions Page, "an applicant must have received a Bachelor's degree or its equivalent from a college, university, or technical school of acceptable standing." Another place to contact is MIT's Internation Student Office. If English is not your primary language will almost certainly need to take the TOEFL (Test of English as a Foriegn Language). If you are asking about undergraduate admission you should be aware that financial aid for ugrad foreign students is almost unheard of in the US. I would say that any international (non-american) student would have a better-than-average chance of getting accepted to a US school since "diversity" has now become quantizable statistic used to rank US schools.
If you aren't sure that you want to get a Ph.D. get some experience first. I knew that I wanted to get a Master's but wasn't sure if I would get in to, or wanted to deal with the hassles of applying to a "top-tier" school. So, I looked for employment at a place that already had a close relationship with one of those schools (MIT Lincoln Lab). Now they pay my tutition and my regular salary with only a one year "stay with us" clause. It turned out to be a great job anyway.

Yes. Pretty much everywhere, management workstation, login and I/O nodes, blade controllers, cabinet controllers, and even the compute nodes now.
Please enlighten me. Who is stupid enough to by a million+ dollar computer without factoring in facility costs?

Linux has perfect* documentation, the source. It also augments this rather verbose documentation in the Documentation directory.
*perfect in the sense that all questions can be readily answered
