  1. ebooks on Digital Textbooks for College? · · Score: 1

    You can find 'pirated' books on usenet, but you're unlikely to find the specific books you want/need that way. Good way to get some cheap (free) reference material though.

    The digital camera idea is fine, except that JPEG doesn't do solid black lines so well. I suspect that 'doing a 1000 page book' in an afternoon or something is more than a bit optimistic.

    Get a locker or two. Don't lug all of your books around to all of your classes. You're in college for gods sake -- you only have a few classes a day and unless you've worked out some scheduling miracle you'll have plenty of time between sessions to stop off at a locker.

    maybe use the digital camera idea for chapters you're studying that week -- quick reference w/out the book.

    Most of my prof's only rarely referred to the textbooks, making them a near total waste of money. A few used them extensively. Try to guess which is which and return the less-used books during the first week or two of classes.

    Most university libraries have course textbooks on reserve. Use that as a resource when you *have* to read something in particular. Or ask a cute classmate to have a 'study session' and mooch off of their book.

    Check in with the prof during office hours. Many will have 'last years' review copy laying around. A little social engineering might get you access to it.

  2. 6 vs. half-dozen on Would You Move to Windows Thin Clients? · · Score: 2, Insightful

    Other comments have suggested 10-20 servers is a more realistic number of servers, but server hardware tends to be a _lot_ more costly than desktop hardware, so 20 servers at $5k each = $100k, vs. 100 desktops at $1k each. Plus you have to license citrix, windows for every client, buy at least a few new computers, or get some kind of 'winterm' (about the same cost as a low-end PC -- $500-700 with monitor). Don't forget the implementation, training admins, hiring or contracting skilled WTS/Citrix admins, upgrading network infrastructure, etc.

    Based on the above, lets call initial costs a wash, or perhaps thin client costs twice as much compared to normal PCs.

    Now it comes down to whether you believe the gartner TCO b*llsh%t. Make some wild-assed assumptions and you can come up with a 'cost model' that will support any position you want to take.

    Our experience:
    Citrix/WTS works well for remote access and for running apps from non-windows platforms. It's also good for remote offices where the function is well defined and there's a small number of users (e.g.: retail locations).

    Problem: Security is essentially non-existant. There is a veneer of what appears to be a 'locked down' environment, but there is always some way to open a help window or somesuch and pop into IE and then *bam* you've got the ability to browse the file system and run just about anything.

    Another problem: Because Citrix/WTS allocates memory per user and does not share between users, vast amounts of memory are needed per server. We have an app that uses 180MB per user, so for 10 users we need around 2GB of RAM. This puts a hard upper limit on how many users can use a memory-intensive application.

    We also use Linux and X-Windows. Running a java swing app that takes about 80MB per user, around 70MB is shared, so each user takes a delta of 10MB. That same 10 user mix uses around 170-180MB of RAM vs. 800MB+ if it ran on Citrix. Also, since much of the app is shared, CPU cache is much more effectively utilized and performance is much better as well.

    Perhaps you could concentrate on migrating apps to X-Windows and running them on Linux servers. This won't work for everything, but it may end up providing a lot more business value.

    Good luck. You'll need it.

  3. Re:A bit different than IPv6 on PGP Universal - Usable Email Security? · · Score: 1

    I'm not sure the biggest advantage of IPv6 is the address space, although that was the most feature touted by the doom-and-gloomers. In some ways that has probably held up adoption since it makes addressing different. IIRC IPv6 supported several other features such as IPSec.

    There is also no advantage for early adopters of some new "secure, better, less spammy" e-mail system, since you'd have to gateway to regular e-mail until a _lot_ of people had switched.

    That was my original point -- back when the Internet was 10,000 hosts at 3,000 sites you didn't have to have many large sites start using something before networking effects took over and you *had* to be running the new protocol.

    Nowadays you'd need thousands of large entitites moving millions of people towards a new standard before it would become worthwhile. Look at the 'P3P' privacy thing -- wan't a big issue until Microsoft decided to make Internet Explorer 6 force it's use. Now you can't run an e-commerce site without returning the P3P header, or you'll miss 30-40% of your visitors. Most new standards don't get that kind of attention, or if they do it is from some proprietary twist to break compatability (e.g.: Microsoft and Kerberos).

  4. Another Me-Too product on PGP Universal - Usable Email Security? · · Score: 3, Informative

    Sounds a lot like what Zixmail (zixcorp.com) and several other companies provide. It would be nice to see some kind of standard emerge that most ISPs offer as a free service -- StartTLS/SSL to an SMTP server, which then looks at a special header or whatnot and contacts a global database of IDs/Keys (e.g.: like DNS for domain names). Problem is that it requires a lot of people to all make up their mind a certain way and it's going to take some time.

    Many of the standards of today (DNS/SMTP/etc.) came about while the Internet was a comparatively homogenous collection of universities, government and military sites mostly in English-speaking countries, with little or no commercial interest.

    Nowadays I'm less confident in the RFC process -- clearly it is still there and still works, but as the Internet has grown, so has the time for a convergence on new and important standards. Case in point: IPv6 -- it's been around for years, but few sites have actually made the leap.

    Suppose a nuclear plant has a problem, you contaminate 100's of square miles with radioactive emissions, possibly contaminate ground water, and generate tons of highly dangerous waste.

  7. Why don't the modems (cable/dsl) firewall? on Should ISPs Be The Little Man's Firewall? · · Score: 1

    I've got two #*$* boxes for cable modem -- the cable modem, and a 'broadband router' that provides a simple, but fairly effective firewall.

    Given that basic 'broadband routers' cost under $80, why can't the ISPs get the cable/dsl modem manufacturers to add this functionality? Config could be initially set to be quite restrictive (e.g.: no unsolicited inbound traffic at all) and then user-accessible for the 'power users' who want to modify that.

  8. use 24/8 on Local Network IPs - 10.0.0.0/8 or 192.168.0.0/16? · · Score: 1

    This will 'black hole' all of the crap that you get from @home and roadrunner zombie worms. Unless of course you're on one of these networks...

    A good scheme for the 10 network is to split it into class B's for large locations and class C's for smaller locations as such:

    10.X.
    where X is the location number 1 for new york, 2 for LA, 3 for hamburg, etc.
    10.1.Y
    where Y is 0 for routers/network devices, 1 for servers, 2 for remote access, 3 for static addresses, and 4-10 for DHCP addresses. 11-254 (255) are reserved for future use.

    Then use 192.168 addresses for individually firewalled segments within the 10.x structure, and 172 addresses for data center stuff like mainframes, backup boxes, secret gigabit backbone links, etc.

    Of course this all gets kind of complicated especially for a small home network with less than a dozen active devices, so you can pop over to arin and find a netblock that isn't assigned or in use and then have a 'designer' internal network number. Works great until some major provider gets the netblock... What the heck -- you're behind a NAT box right? 1.2.3.X here we come!

  9. lead balloon filled with hot air on Managing Linux and Virtual Machines? · · Score: 5, Interesting

    We've got a production linux instance running under VM alongside our production VSE system. Since the box is fairly underpowered we get a minimal slice of the CPU. This makes the system respond like a 286 with the 'turbo' button turned off.

    When the VSE instance bombs out for some reason, and we get effectively 100% of the CPU it responds like a pentium... maybe. Think P166.

    Unfortunately in our circumstance we can't 'turn on' more MIPS because then our VSE instance is running on a 'bigger' machine and we end up doubling our licesing costs. Other alternative is to turn on the ILF (integrated linux facility) which dedicates 120Mips to linux only, without affecting other licesning, but that costs $150k. You can buy a lot of 2-way or 4-way pentium boxes with decent RAID arrays and get much better performance for that kind of money.

    So if your shop is run by some sort of morons and you've got 100's of spare MIPS to burn, then Linux on the mainframe probably makes some sense. Otherwise, just get some intel boxes. Any savings the mainframe provides in terms of power, cooling, and ligher administration is going to be offset by massive complexity, poor performance, and a lack of easy support for a bizarre platform that few developers have access to.

  11. My Toolkit on Required Tools for PC Repair? · · Score: 1

    I've had pretty much the same thing for the past 10 years. I started with a very simple one like the(Belkin 11 piece toolkit. This is a good start since you get a nice case, a box with compartments to keep extra screws etc. in and crappy tools that you can use until you get better ones.

    I chucked the IC extractor, and the elastic loop is perfect for a small wirecutter and a smallish (very cheap) pair of needlenose pliers.

    The socket drivers and torx T15 were good enough. You have to use them once in a while, but not so much that it's worth investing in better ones.

    I found that I often need both large and small phillips and flathead screwdrivers, so I chucked the 'large' phillips from the kit and put in a 4-in-1 type where the shaft pulls out and reverses to switch between flathead and phillips, then each bit pulls out to switch between large and small. Nice comfortable handle too. The large flathead was removed to make room for other stuff.

    The small phillips and flatheads in the kit are really lousy, but servicable. I chucked one in favor of a two-in one unit offered as swag by many vendors. Longer shaft has a flatheat, on the other side is a shorter shaft with a small phillips. Most versatile tool in the kit since the flathead can work larger phillips screws. (one of these is pictured in This kit.)

    I chucked the other small screwdriver and used the loop to hold a small maglite flashlight (AAA size I think). This also holds 1-2 slot covers.

    The parts box has an assortment of screws, jumpers (small and large), some twist-ties, etc. that I've picked up over the years.

    One piece of paper and a pen for notes.

    Static strap stored under pliers and wirecutters, static strap lead bundled with a twist-tie shoved next to something so it doesn't fall out.

    Tweezers were useless - trashed. Needlenose pliers are much better.

    The 'three pronged parts retriever' is almost worth the price of the whole kit. Very useful for holding small screws and 'getting them started' in a tight spot.

    Over the years other parts have come and gone -- panduit jack crimper, mirror, cage nut tool, etc.

    I've found that most of the commercial kits (e.g. the $60 toolkits) are filled with useless things like soldering irons, or tools that are too low-quality for regular use (e.g. bad wirecutters) and the larger cases are too bulky to carry around casually. Much better to spend 12-20 bucks to get a case and some basic tools then spend the other 30-50 bucks on good tools. It's worth it to spend a few bucks on the tools you use a _lot_ (e.g.: screwdriver), while the junky tools (like the included T-15 torx) are OK since you only need to use them once in a while.

    Curve was typically 29+ A, 28 B, 27 C, 25-26, D, 24 and under an F.

    I'm still very bitter about this. Glad I got to pay a lot of money to get screwed over by a broken system. I ended up going to an other school which worked out a lot better. Smaller classes with teachers interested in teaching.

    2: Companies that have sent work offshore will have very mixed results -- just as they have had with American workers, but much worse.
