Portable Hubs?

· Score: 1
One minor problem with this: If the device wasn't designed to be run off of batteries, then it is expecting a continuous supply of the proper voltage. When the batteries run low, you will be feeding under-voltage to the device, and it may not have circuitry to shut itself down in this instance. Therefore, you may end up frying your hub. If you use a battery pack, make sure you wire up a circuit that cuts off power when voltage drops below an acceptable level.
They started using the shoe straps, and the defect and return rates went down more than enough to make it worth it.
Basically, you don't have problems with static when your only dealing with a small sample, but increase the sample size, you are increasing your chances of causing damages to something within that sample. So, for a manufacturing operation, I'd say it is worth it.
Uh, they do NOT hold "1.44 MB". They hold 1,474,560 bytes, which in decimal is 1.47 MB, or if you are using base-2 (2^20) megabytes, that's 1.406 MB. Either number does not look like 1.44 MB.
The reason that everybody calls them 1.44 is because they hold 1440 (base-2) kbytes, then people shorten this by performing a base-10 division to get 1.44. This mixing of a base-2 (1024) division followed by base-10 is just... weird.
Instead of treating OS products like you would commercial code, internally you put it in the same catagory as in-house developed code. So, however you support in-house stuff, use the same methods for OS code.
Ok, do these businesses also record all phone calls? Do they also have microphones by the water cooler to grab conversations? If voice conversactions are excluded from the data retention laws, what about teletext devices used by the deaf? If teletext is also excluded, then what's the difference between that and instant messages?
Yes, however software that is developed internally would have the same problem. Company IT departments generally have a lot of in-house developed software. They will then just end up treating OSS the same as in-house software.
An easier way (and not needing xterms) would have been to use script:
$ script
Script started, output file is typescript
$ telnet remotehost ...
remotehost $ cat filename ...
remotehost $ exit
$ exit
Script done, output file is typescript
$
Of course, instead of cat, use uuencode for a binary file...
Since the major issue with digital signatures is proving a particular key pair belongs to a specific entity, why not merge the two signature technologies (digital and physical)? What you do is have someone print their public key in a contract, with language stating that they authorize that public key to verify digitaly signed documents (might have to also specify the specific technologies in the contract), then sign that contract with pen & ink. You keep that contract on file, so you then have physical proof of ownership of that public key, and have a better chance of it holding up in court.
One other thing that helps, is go to a 1-week training class or two... not for the knowledge you gain in it, but to build up contacts. Esp. if you are already familliar with the topic being taught, you can impress others in the class & the instructor, hopefully enough that they can recommend you to their contacts. A guy that I work with had taught a sysadmin class at a local college, and ended up hiring a couple of his brighter students.
Of course, it costs a bundle to take the classes, so that is one drawback.
Why not just put your content in a non-published directory, then have a random symlink pointing to that directory? Your front page would link to the content through that symlink, using a server side include script. Then have your scripts generate a new symlink every 10 minutes or so, and the SSI would always grab the current valid link. (You would also need to keep the expired links around for a period of time to handle overlaps). That way, you don't involve anything that's client side (refferals, cookies, etc.)

Actually, I know that in Huntsville, AL, (where there is a fairly good size hill/mountain), they have had a service similar to this a number of years ago. You pointed something that looked like a mini satelite dish at the mountain, and got your cable tv through that.
Actually, I've got a solution for EULAs. I go ahead and click Accept, then I fire off an email to the support line along the lines of "By receiving this email, you accept my modifications to your EULA as follows...", and follow it with my own terms. I follow it up with "By not re-writing your EULA, you affirm that the above exceptions are valid".
Actually, they didn't "forbid" it per se, as in they didn't have it in their license that you couldn't port it to Apple, however they did formally protest it, and encouraged others to not support GNU software on Apple. The software they distributed contained an/etc/Apple.txt file that had a rant about it.
It's very simple. Your box is Unimportant(tm). If bad guy wants to break into Important(r) box, he/she will do it through your Unimportant(tm) box once it is owned. Now Mr. FBI agent comes a knock'n on your door, cause your computer broke into mr FBI man's computer.
One thing I was wondering, my employement contract contains the verbage "inventions, innovations, or ideas...related to work I do for the company, or related to current or planned business activities of the company... [are owned by the company]. Since I am a systems admin, which can include some programming, does this verbage cover all program catagories ("related to work I do for the company")?
Or, better yet, put some wrapper code around the library in question to turn it into a server process. Then have your program launch it and make socket calls to it. The only part you'd have to gpl then would be your mods to turn it into a server process. Would this work?
A co-worker of mine had a similar experiance, except that her name, number and title were listed as a reference on her friend's resume that was posted on the job sites. She was getting flooded with calls from headhunters. Apparently, they try harder on people who are currently employed and not seeking a job change than they do on the un-employed, the theory being that if you do not currently have a job, you must not be very good at it.
Not really. For example, they could include encrypted mp3 tracks on the cd for use on your mp3 player. In order to decode them, you must register on their web site, which will give you a unique serial number which will be water-marked on the resultant decoded mp3 file. You also would be required to supply a credit card number to be used for identifying information, and "sign" a click-through license that allows them to charge your card for any coppies they find with your watermark on it in the wild.
Actually, the theory goes (according to a show on Discovery channel):
1) Global warming will cause the polar ice caps to start to melt.
2) This will cause the oceans to become less salty near the poles.
3) Since the heavy salt concentration at the poles drives ocean current, less salt means the currents will reverse.
4) Once it reverses, the planet will become signifficantly colder, since the ocean currents are responsible for distributing warm air. Also, once the currents reverse, it will take thousands of years for them to go back the other way.
Apparently, it will only take about a hundred years or so of increased temps to cause this to happen, and start the new ice age. (Note: I'm not sure if I believe this or not, but it is interesting nonetheless).
There was a case back a year or so ago (I don't have the linke, but it was popular enough to be on some TV news magazines) about a teenager that had to pay 6-figure fines to the SEC for pumping up stocks on message boards then dumping them when the price went up. I wonder if this case will allow him to get is money back?
The general rule is that you don't "feel" a cpu speed increase until it is at least 20% faster. I would like to see some double-blind studies to see at which point people can preceive the speed difference, and at which point any increased speed is meaningless. For example, films are shown at, what, 15 frames per second? and they appear as full motion. So what difference do you get playing quake3 at 60 fps vs. 70 fps?
Also, don't look for other "fun" projects relating to computers. Try a different hobby fields, such as woodworking. Not just building furniture from existing plans, but come up with your own designs. This requires an equivelant, but seperate set of skills. Or try auto mechanics. Start by taking apart a small lawn mower engine (and put it back together -- take snapshots with a digital camera as you go in case you forget where a part goes).
I've actually put together a digital jukebox for my truck out of a bookpc, and got the user interface issue licked. It consists of: a bookpc (socket370 mb, case, power supply, floppy, cdrom) for $160, a celeron cpu -- $50, 40GB hd -- $75, LCD display module -- $8, 10-key keypad -- $10.
The user interface is a small C program that takes commands from the keypad (i put custom labels on the keys for play, stop, track/album/playlist selection, record, etc.) and displays status info on the lcd. Recording is self-contained, you put a cd in, hit the record key, select a album slot (it auto-selects an empty one), select the tracks to record (defaults to all), then it starts ripping. You can play while ripping, and compression is done in a background batch process so you can have all the quality settings on high without waiting for compression. Tracks are instantly available to be played even if they haven't been compressed yet, and the batch job auto restarts if system is power cycled. As soon as I get a chance, I'll put the project up on sourceforge, hopefully it will get to a point where it can be downloaded as an iso image, and you can plop the cd in a new system and it will auto-install everything. The goal is no pc/keyboard/monitor needed.
Actually, if I remember right, the Netscape download was rather large, and there was a "bug" in IE that caused it to not be able to download files that were larger than [size of Netscape Navagater - some small amount].
