They do, Here are all the graphing calculators HP offers: http://www.hp.com/calculators/graphing/index.html The 49g was a terrible mistake, but HP seems to have redeemed itself, the 50g has and SD memory card slot, USB and IR: http://www.gizmodo.com/gadgets/gadgets/hp-50g-calc ulator-makes-nerds-pee-themselves-201990.php I've had a 48G for a while and never needed anything more.

The 48GX isn't sold anymore, but there are others now that they do make . They range from the non-RPN HP 9g for $29.99 (but seriously, why bother if it's non-RPN?) to the HP 50g for $149.99 - which supports RPN, has 2.5MB RAM and an SD card slot.

I own a 48GX and have loved it, but the screen is broken and has leaked liquid crystal across a portion of the screen, so I'm due for a new one - I don't need graphing support, so I'll likely go with the $49.99 33s - cheapest one they make with RPN. I just don't like the chevron button layout.

Consider one of the under-$50 TI-competitors that will get you through Freshman Calculus, then when you get to college see what's available.

Whatever it is, it will be better or cheaper than what's here today.

HP's 9g probably isn't enough but at $30 it's worth checking out.

Casio has the FX-7400GPlus for under $40.

Used TIs can be had for under $60.

The only reasons to spend more are if the time-savings are critical or if your school requires features these less expensive calculators don't handle.

As long as you are a student, don't do anything with a calculator you couldn't do in principle with pencil and paper.

Remember, the generation before yours survived high school and college without the benefit of graphing calculators, and the generation before that used pencil, paper, and tables. Most of them turned out okay.

Do not forget the HP products either:

There is also some Japanese products that rock. Windows and Unix do not have all the market yet. It is nice that we get more and more of these advanced features on Linux.

How about $480? Yeah, it's $40 more than the target, but it's also has a 160GB HD (whereas the bottom end mac mini only has 60GB unlike the 80GB you quoted), a DVD burner, and it comes with a keyboard and mouse. Add wireless for $20, or $10 after rebate. Either way, you get more computer for less money.

I'm not the GPP, and I'm not saying the bottom end Apple products are a ripoff -- they're a decent value for the money -- but they tend to rapidly escalate in price for minor features. $200 is a lot to pay for a 200MHz increase and 20GB of HD space. They bank on the fact that people don't like to buy bottom end because it will (or they believe it will) be useless in a year.

... becuase last week I ordered a server from HP with 2.5" 15k drives HP.

OLED will be IMO more feasible for use in laptops before SED. OLED is already being used in small devices like mp3 players, car stereos, cameras, and stuff like that, while SED is not. Sony has a 27" 1080p TV on demonstration in Vegas, as well as many smaller models.

As you can see, they're already very thin (the one on the second pic is about as thin as the LCD on my laptop) and from my understanding of how the technology works, individual pixels will be powered proportionally to the brightness needed, so black pixels won't be drawing anything at all.

I bought this charger about two years ago and I love it. The batteries last forever and the charger is perfect - very small, portable (charge in your car's lighter) and fast - I use the slow charge mode and it takes about 4 hours. Even better, it has trickle charge so the batteries aren't overcharged but will remain at full power. It's worth the $50 investment (with 4 batteries!), trust me. I was redeemed even further when I saw that HP has moved to using MAHA Batteries as well for their rechargeable AA battery solution.

Good point, but bad example. Sabre migrated to a generic database (which MySQL and HP significant contractors on the project).

http://h71028.www7.hp.com/enterprise/downloads/Sab re-HP-MySQL-case-study.pdf

But your point is well taken, and practically all the large financial institutions (Fidelity, UBS, Merrill Lynch, etc) use KDB from kx.com; also APL derived like I think the old Sabre system was.

Maybe you should read up a bit on Mac solutions before you comment- software like Apple Remote Desktop, FileWave, NetOctopus, NetBoot/NetRestore, Radmind, HP OpenView, Deep Freeze and resources like AFP548, Mac Managers, MacOSX Labs, MacEnterprise, and of course Apple itself (I'll leave finding Apple's website as an exercise for the reader ;) make running large Macintosh installations fairly easy. There are plenty of UNIX/CLI tools and scripts out there, and Apple offers professional certifications if you want paper to show a potential employer.

Well I guess it depends on how much they want to spend on tapes. Not sure what SDLTs run for anymore. As long as you've got decent software you should be able to work out a rotation that suits your needs & budget.

I haven't played with CommVault, but may be looking at it this year. I'm currently running HP Dataprotector which I quite like. I haven't used it in a small setting, but at approx. $1,500 or so for the one drive version it gives you a lot out of the box. I know that's not cheap, but it does work quite well. As for network backups the basic license will do as many machines over the network as you want. I'm only using it with Windows, but it does support other OSs as well.

You can license other options on top of that such as Exchange & such. It's reasonably priced until you start getting into the fancy stuff.

It's the first backup software I've used that doesn't irritate me too much.

On OpenVMS?

No, I'm not being facetious. It still works great. Especially over those serial connections.

As mentioned here, it's possible for conservative GC to ignore a whole linked data structure such as a queue, which can be arbitrarily big, just because of a single non-pointer position in memory.

I agree that it's not likely, but I just don't feel good by using such an inelegant and disaster-prone technology in my programs! Maybe I'm irrational, maybe I'm a purist, maybe a bit of both, but I just don't like the idea.

Plus, when I heard that the D programming language uses it, my opinion on the language also decreased.

Here is something that I found about this. Not very good news for conservative garbage collection, I say...

I was helping a friend get set up with a new computer. It's a sweet, sweet box from HP: Athlon 4200+ X2 processor, 1GB RAM, DVD burner. It's an HP Pavilion a1647c-b, and it cost US$900 (which included a nice widescreen LCD display with both analog and DVI inputs!). I upgraded it with a passively-cooled nVidia 7600GS graphics card, so it's now using the DVI input on the LCD display, and the display looks great.

I wanted to install Ubuntu on it, but I haven't done so yet. Here's why.

It turns out that the system doesn't come with an XP install CD. No surprise, Microsoft requires OEMs to provide "recovery disks". But it turns out that the system doesn't come with recovery disks either! It comes with a utility for burning a custom set of recovery disks. The manual says you are permitted to burn exactly one set of recovery disks.

It turns out that you need 18 blank CD-R disks, or 3 blank DVD+/-R disks, to burn your custom set of recovery disks! So I went home without installing Ubuntu.

The next day he bought a stack of DVD+R disks, and I went back. The recovery disk utility took a long time to burn the first disk, and then it said "verifying" and sat there, indicating 1% progress. So I left again without installing Ubuntu. He left it running and it never did finish.

So now he has a Windows system that he doesn't dare use, because if it gets messed up, there is no way to restore it. He told me he would call HP tech support but I haven't heard back from him.

By the way: it would have been easy to install Ubuntu before the first boot-up. I booted an Ubuntu CD and used it as a live CD, and looked over the hard disk without modifying it. Initially there was a 20GB partition and a whole bunch of empty space. On the first boot, the Windows system expanded the NTFS file system to fill the whole bunch of empty space. If I had just created a couple of partitions at the end of the empty space, I'm pretty sure that Windows would have left them alone, and then it would have been trivial to install Ubuntu. (Of course, if I had done that, I would have had a nagging worry that the recovery disk fiasco was somehow my fault. Because I didn't touch the machine before first boot, it's clear that the recovery meltdown has nothing to do with me.)

I was tempted to just grab a copy of XP and do a full re-install. But this particular system came with XP Media Center Edition, and I have no idea where I can get an install CD of XP MCE (or how much it would cost).

I'm half-tempted to buy one of these systems, though, because it was a good value for the money, and Ubuntu recognized all the hardware, right down to the flash card reader.

garbage collection ... No virtual machine How do they square that particular circle?

Trying to get an exhaustive list of all WLAN adapters supported under Linux is the wrong way to approach the pb because there are literally hundreds of them on the market. However they are all based on only a dozen or so of common WLAN chipsets: Zydas ZD12xx, Atheros, Intel PRO/Wireless 2xxx, etc. It's easier to assemble a list of supported chipsets rather than a list of supported adapters.

Firstly, you can have a look at the drivers/net/wireless directory of the kernel source code. From there look at the Kconfig file (compilation options) where every WLAN chipset natively supported by the kernel is succinctly described, and pointers to additional details about the drivers are often provided: READMEs, URLs...

Secondly, some WLAN chipsets are not natively supported by the kernel, but instead by third party drivers from independent open-source projects (most of them will be integrated into the kernel in the near future). So check out this webpage for example (the interesting section is "The devices, the drivers - 802.11+, 802.11a, 802.11g"), it has been written by Jean Tourrilhes who got involved as a developer with early work on the Wireless framework in Linux. He wrote this page specifically to gather info about all the existing WLAN drivers in a central place. It contains info about third party drivers as well as drivers natively supported by the kernel. The page is slightly outdated though, so check out this wikipedia article about open source wireless drivers for a complement.

Thirdly, other WLAN chipsets are supported by proprietary drivers only, I recommend you stay away from them.

At this point, personally, I like to take decisions about hardware purchases "from the bottom up". In other words, I decide which one of the WLAN chipsets I would like my adapter to be based on (since it determines the major features of the device), and then I search for adapters using it. Usually the website of the driver maintainer, or the mailing list of the driver project, or the driver documentation are good places to look for list of adapters based on particular chipsets.

I've built a few 802.11 networks in rural areas (some solar powered!) using really low end hardware.

Frequently devices get smoked by high (lightning) or low (flat batteries) volts and stop operating completely. Sometimes they just start acting strange. I am going to start using ethereal (now wireshark) with the appropriate card to hopefully find out a bit more about what is going on when there is funny behaviour.

HP is probably the only laptop manufacturer that publishes COMPLETE disassembly/repair manuals. My nx6310 had a manual with instructions on removing and replacing the keyboard, heatsink, CPU, display and other parts. You may download the manual freely here: http://h20000.www2.hp.com/bizsupport/TechSupport/C oreRedirect.jsp?redirectReason=DocIndexPDF&prodSer iesId=1839143&targetPage=http%3A%2F%2Fh20000.www2. hp.com%2Fbc%2Fdocs%2Fsupport%2FSupportManual%2Fc00 805752%2Fc00805752.pdf

What I never get about these prin on demand things is how can they get the cost per page down. E.g. Laser printers may have a cost per page at about 0.05 cents, that would mean $27 for one 550 page book, that excludes the hardcover. Even if this thing 50% cheaper it's still very expensive..

But... When I was viisting South America there were lots of copy shops that printed A4 on both sides for 0.10 bolivianos * 275 page = $3.3, that's almost cheap enough. But these photocopiers were analog monster tuned and pruned, made from easily maintained parts with cheap ink.

On an HP, I can:

• PXE netboot / install
  
• Get a remote graphical console (or text if you don't pay for the advanced license key)
  
• Power cycle / reset
  
• Utilize virtual media (CD / floppy image on a web server or on the management client's drive)
  

Wouldn't bundling a Linux distro (which is technically NOT a HP product) run foul of this law as well?

Anyway, here's a link to a page in HP's website offering BOTH Windows and Linux pre-installed... http://h10010.www1.hp.com/wwpc/us/en/sm/WF04a/1245 4-64287-89301-321860-f49.html?jumpid=re_R295_prode xp/buyguides/computing/desktop5000&psn=desktops_wo rkstations/desktop_pcs

Because there's a cost associated with offering different peripherals, both in terms of increased complexity on the production line and also future support. The number of people buying, say, Ubuntu installed on HP desktops is too small to justify the additional support and manufacturing commitment; whereas, say, enough people choose between the NVidia ATI cards.

What are you basing your hypothesis on? HP doesn't manufacture any machines with Ubuntu preinstalled, so of course nobody buys them.

Additionally, go to an OEM like Dell and look at their choices. You will notice that, for each performance and product level, there is usually only one choice. You don't see an ATI X1900 being offered alongside the GeForce 7900 - there is no reason to complicate your operations by offering two competing products that are arguably in the exact same performance category.

Yes, but since we're talking about HP, try looking at their website. Each machine has an Intel and an AMD version, usually within $50 of each other. And in many cases you'll see choices for both ATI and nVidia video cards.

Well, listening to that was simply painful... however, despite their inability to understand so, they were correct. According to this link: http://www.hp.com/sbso/wireless/MNY50079-VZAccessP ricing-V1b.pdf
The going price is INDEED $0.002. So yeah, it was .002 dollars.

But still, wow... I don't know how they didn't get it. There was only 1 flaw in his explanations, but that flaw should not have affected their understanding. The only problem I see, is that after they multiplied .002 cent/kb, by 30,000 kb (whatever it was), and they come out with 71.## dollars. He should stop there, and say, where did the dollar come from. I know he did it somewhat, but he'd go into complaining about it, saying they forgot the translation. Although they SHOULD have realized that when he complained, since they didn't the first 2 times, he should have just stuck on that part. .002 cents/kb times X kb, gives an answer in cent's. therefore the calculator answer of 71.## is 71.## cents. thus 0.71## dollars.

Not to say he didn't do that to the point that any college grad would understand, but the only thing I can think of is trapping them in their own reasoning. You multiply cents per kb, by kb, and what do you get? You say dollar, but that means that means that you multiplied by dollars per kb. Math isn't even the problem there, its their inability to keep track of a unit. Now I have trouble with that on my engineering stuff, but that's Coulomb-seconds per amp-meters or something, you get into multiply numerator and denominator terms it gets all screwy. The best plan would be to explain, you multiply cent's per kilobyte by kilobyte, you get the amount of cents that correspond to your kilobyte usage. So even though 71.## may look like a dollar notation, you have just calculated cents.

What made me wince was the how they respond to the examples. You know the difference between 1 cent and 1 dollar? (immediately) yes. You know the difference between half a cent and half a dollar, or .5 cents and .5 dollars? (immediately) yes. So you see the difference between .002 cents and .002 dollars? (Long pause) No. That's just beyond silly. Same number, different unit, if the units are not equivalent then they MUST be different, irrelevant of whether you understand the number, as long as it is the same.

Sorry... just when I see something like this.... I worry about the human race, that somebody who controls part of a powerful company can't even keep EXAMPLES straight, much less currency.

Oh, that's so unfair. Go look at this little bunny I wrote last year, pointing out the entire Web Service SOAP stack and its belief in seamless mapping between Java/C# and XML was a load of fundamentally unachievable bollocks.

When I was at the IEEE conf presenting it (and getting best paper, BTW), I had to put up with three days of academics stuck in the depths of their little web service, none of whom seemed to step back and notice that what they basing their work on was junk. Instead they were using Apache Axis or similar and repeating exactly the same mistakes enterprise developers do: they believed IBM and Microsoft knew what was best for them.

I actually prefer open source conferences. Good talks, good audience, ubiquitous beer.

Enjoy,

I think you are stupid. You don't understand the specifics of the technology, so you're assuming it's a scam.

Obviously the data storage scheme is far more complex than anything you have experience with. How stupid do you have to be to think the color of the dot on paper directly determines an individual bit? This isn't about storing bits directly on paper- there are only 2 possibilities in binary, why would you need 256++ colors to store binary bits? The LEAST complex algorithm I can think of (assuming no shapes, just dots of various colors) is that each color represents a certain binary sequence, say of length 8 (2^8 = 256). That means that with 256 colors (256 unique states) you can store 8 bits per dot. Assuming a 300x300 dot per inch printer, we've got 90,000 dots per square inch, each being 1 of 256 uniquely identifiable 8 bit sequences. 90,000 x 8 = 720,000 bits per square inch, or 90KB per square inch.

Try a 1200x1200 dpi printer: 1,440,000 dots per square inch = 1.44 MB/in^2

Of course, this is assuming 8-bit color. In reality, a photograph in 256 colors is, well, not a photograph. Say we have a 24 bit printer and scanner (24 bit is regarded as life-like, and the standard for printers and scanners), thus 2^24 = (approximately) 16.8 million uniquely identifiable colors. This means we can encode unique sequences of length 24 bits per dot. At 1200x1200 dpi, we're talking 1,440,000 x 24 = 34,560,000 bits per square inch or 4.32 MB/in^2.

Using only colored dots. Throw in printers with even higher resolutions like these from HP at 1200x4800 dpi, the even higher density of data storage available from the use of shapes (adding even more uniquely identifiable states through shape, size, order, orientation, special characteristics, and relative positioning), and some clever compression and encoding algorithms... and you can easily build pretty high density storage.

By contrast, IBM is one of the 3 remaining American companies that still makes general-purpose, complex, and powerful cores for crunching scientific applications. The other two companies are AMD and Intel.

And, as a followup to your question, the answer is "yes". Check out HP and Yahoo! in a "view source" window. Lots of "div" tags and not any "table" tags that I could see in a casual glance.

but I was under the impression that the deal worked something like this:

It did. Past tense. Today, Dell offers an entire frigging line of Linux PCs!. As does HP.

The fact that you don't see them on the shelves at Wally World is simply the nature of Linux.

Apple is slightly behind with that technology.

XP won't touch them, and when I went to the HP driver download pages and typed in my model number, it said "no support for the 64 bit edition of Windows XP Professional is available yet" I can't find the specific support page (I'm not on the 64 bit computer right now, and the "driver download" page just offers me a 32 bit driver instead of a link to the support pages.) However, here's a link to the support forums where some other people describe the same problem: The link

I'll look more later for the specific help page about it.

I know this is an older link, but mod the parent up: (a bit of proof)

He's exactly right. You might argue they make their money from their investors...but most specifically it's received by getting companies like Dell and HPQ (notice the text: "HP recommends Windows® XP Professional!") to purchase boatloads of licenses...

On a related note: try to build your own PC on the Dell or HPQ websites (see above links). You won't even be given the option for "no OS," let alone Linux, you MUST buy Windows!

I recently received an HP Pavillion dv9000 laptop to replace my E-machines M6805 under Best-Buy's lemon policy. When I bought the E-machines laptop, I purchased a Samsonite laptop carrier that fit the 17-in screen of the M6805. When I got the replacement, I took the laptop home to discover that the HP dv9000 was almost an inch and a half wider than the M6805. According to the spec of the dv9000 at Best Buy, the width of the laptop is 18 3/8 inches. So I decided today to go back to Best Buy to see if they had a wider laptop carrier. No go. The widest carriers that Best Buy even sold were around 16 1/2 inches wide. Even the Best Buy associate recommended going to a luggage outlet to find a compatible carrier. Talk about inpractical. :-)

For under $2k each, we just got a bunch of HP DL360 G5s at work. Granted I work in education... But still $2,000 is too much for a goddamn desktop machine.

The Internet Archive has an ongoing effort to measure disk drive reliability. They have several thousand disk drives for which they are collecting data, and for the year 2005, about 2% failed. This is better than previous years; a few years back they were experiencing 6%/year failure rates.

They send them back for warranty replacement, I'm told.

Maybe this does not apply to you but...

Virtualization is not the answer to everything and no company selling virtualization solutions ever stated it was. An individual assessment need to be made based on server loads, types of load (CPU and disk IO), timing of loads, specialized hardware requirements like dongles or fax boards and similar that do not support virtualization. VMWare has an elaborate set of planning guides and tools for sizing, planning, and moving over from a physical to virtual environment. They also have very detailed guidelines on what should and should not be virtualized.

http://www.vmware.com/news/releases/vac_services.h tml
http://h71019.www7.hp.com/ActiveAnswers/downloads/ VMware_Infrastructure_3_planning.pdf

That links above are just examples. The planning tools are mature enough that if you tried to virtualize something and it failed, you probably missed or underestimated your actual requirements in the initial planning and assessment stages of the process.

What happens if/when the system gets borked and you need to have access to a serial console to effect repairs?
