My quick check at CNET Reviews...CNET Reviews Notebooks includes battery tests while running BAPCo MobileMark 2002. From CNET's "How we test" page:
The benchmark runs the following applications: Microsoft Word 2002, Microsoft Excel 2002, Microsoft PowerPoint 2002, Microsoft Outlook 2002, Netscape Communicator (Mozilla 5), McAfee VirusScan 5.13, WinZip 8.0, Macromedia Flash 5.0, and Adobe Photoshop 6.0.1
You mentioned DVD watching, so I excluded uber-portables without built-in optical drives from my quick search. Here's what I found among relatively recent reviews: ... MobileMark also includes a conditioning run that prepares a notebook's battery for testing by draining the battery completely, then requiring that the battery be fully charged before an official test run can commence.HP Compaq Business Notebook nx5000 (review): 6 hours, 4 minutes (15" 1024x768, 6.2lbs)

Re:Is the processor clock rate trend coming to an
The Celeron is a severly crippled chip, unlike the Duron, which is a respectably performing budget processor. It only has 128KB cache, which is CPU sucide on a P4 core...One would be much better of with an Athlon XP, Duron, or a slow P4 as a budget processor.
He said he had a Celeron laptop. For a budget laptop processor, I think the best choice for most people is the Celeron M. It shares the same architecture as the Pentium M (Banias and Dothan), but has "only" 512KB L2 cache and no "Enhanced Speedstep."Tom's Hardware reviewed a Celeron M notebook and, unlike the old P4-based desktop Celeron (128KB L2 cache), it is not at all crippled. Here's a link to the review: Does Everything Have To Be A Centrino? Intel says "No"!
Unfortunately, Celeron M notebooks aren't as cheap as notebooks with cheap desktop chips. The HP Compaq nx9020 (1.3GHz Celeron M) "starts at" $800, but that's with Intel integrated graphics, CD-ROM, and 128MB of shared memory. But for those that want a budget laptop with high performance, low power, and thin-and-light dimensions, a Celeron M is probably well worth the extra money.

Re:Sharp Zaurus?
As I've owned a Zaurus 5500, Tungsten T3, and currently own a HP iPAQ 4155, I definately have to give the "coolness," "gadget," and "power" to the iPAQ hands down.
User replaceable battery (one of the issues with the Tungsten), 400 MHz XScale processor (whole lot more powerful than the 5500), integrated Bluetooth (more than the Zaurus has) and WiFi (more than the T3 has) and with a couple of third-party apps to "fix" the annoying things about the Pocket PC operating system I'm most definately in love with this iPAQ...
I'm sorry, the handwriting recognition on the Zaurus sucks (Decuma OnSpot for PocketPC, OTOH is able to decypher my hardly intelligable chicken-scratch) and my fingers are fat enough that trying to use the thumb keyboard is annoying at best. WiFi, while not essential in a PDA, is damn nice (access to the fileshares on the Windows network at work while doing things where a laptop isn't readily accessable but I'm in WiFi range is schweet) and gives me the ability to use Pocket Putty to ssh into my fileserver at home while sitting on the couch.
The Zaurus has a cool "geek" factor, but really, I got tired of the shitty quality of the PIM apps and fighting with the device to try and get it to sync got old after about 3 weeks. -
Corporate PushThere was something by Andy "ange-ftp" Norman of HP Laboratories and some colleagues that did that only more aggressively. Anything with the code red hole had IIS turned off.
This stuff was not a worm (it was centrally managed), and deployed inside the HP class A network (15.*.*.*), where all machines are owned by the IT department. Thus they could get away with it. Inside the firewall you can do this thing -companies and universities are obvious places. Bu t I wonder about the big broadband ISPs, I dont think I want them scanning my box, as before long the MPAA will want them shutting down BitTorrent services.

Re:Old IBM
If the drive lasts for 3 years, it will almost always last for 5
I've experienced something different. At work we have about 300 20GB drives in desktops. They pretty much failed at consistant rate up until our 3 year lease expired. Of course a large percentage of the failures were a certain model Fujitsu which has a class action going on it right now. So far I've recieved about 25 seperate copies of settlement paperwork claiming my company can get up to ~$40 for each one we've had to replace. Combine that with the 32MB USB flash drive HP/Compaq is giving out for every laptop we identify to have defective memory and the IT department slush fund can be spent on a beer bash and porn file swapout at a medium sized hotel. I don't see that happening anytime soon though so the paperwork for everything is still in my inbox. -

Re:Breath deeply and look at the specs...
Obviously, you probably think a Mac, SGI, or the ever popular for OpenGL pSeries is cheap as well, given the price bracket of the cards to run this beast, $300-400+. With the realistic low end at the 7500/Mobility FGL 7800(The only chip solely in a non Apoo or jobstealing laptop)- and the highend (read: always out of reach of mere mortals due to the oligopoly created by the buyouts) is around the x800.
But you arent forced to do X, buy X or involve yourself with X
Well, that doesnt justify your point anymore, since some of us dont have shitloads of money.
To allow anything lesser means a sacrifice in innovation
This one is probably from the gaming community that isnt old enough to remember when one had to actually made your equipment last for a long time (when a usable PC still cost $2000) by getting every inch of that hardware used before thinking of that new upgrade. I'd think innovation would be to step up to the plate and get all the performance/quality out of the lowend/midrange before those who just blindly buy whatever is topend for $500+ expecting that everyone has their resources at hand. I'm not exactly asking for one to go down to Virges or integrated, but asking for innovation to happen within the hardware that's in the low-midrange first (read: Radeon 7500-9600 non LE).

Thanks Office DepotIt's amazing how easily people will throw stuff into the trash without a second thought for the environment or that the equipment could actually be reused. Maybe folks need to get pictures of trash heaps and landfills seared into their consciousness.
I applaud Office Depot and HP for their efforts. Perhaps it will stir other vendors into action.
According to this press release, HP already has 2 pretty large facilities for recycling electronic equipement. They already have a pretty decent recycling program for their equipment and are currently offering a coupon when you recycle and then purchase new hardware from them. [Nope, I'm not affiliated with HP!]
I personally wouldn't mind paying an additional few dollars for each piece of computer hardware or electronics if I knew that I could easily recycle it at the end of its life. The recyle option should also be transferrable to anyone that I sold it to. After all, what's $5 more on a $500 product?

Re:Getting Rid of The Obvious
DEC didn't go tits-up, it was bought by Compaq who was then bought by HP. HP then had a quandry on their hands, they had AlphaServer, VAX, HP 3000/9000, NonStop and SuperDome large systems lines. Obviously some of it had to be cut so they cut Alpha and the already EOL VAX stuff and migrated those users to newer hardware running OpenVMS or HPUX. HP 3000/9000 they put on a long term EOL with unfortunatly no real migration plan other than moving to one of HP's new large system lines. If you want to see the road map HP has a ppt presentation here.

Re:True .... bu(d)t:
If I pay one of my specialists extra because I think he outperforms the rest, I have to pay all specialists extra. Equal rights stuff. This effectively means that you basically can't reward people individually. You are always rewarding a group of people. Effectively this leads to job-titles you only find in Dilbert, because this gives you the possibility to reward individuals who care, work overtime when needed or just perform in an extraordinary way (like not laughing at a customer when he says that his core business runs on windows and such...).
If not for the other things, this wouldnt be half bad if it were executed properly and if you didnt have the runaround you described(Retitling) - then I'd not mind seeing this in the States. This would make people think twice about hiring someone.
And the best of them .... as an employer I have to pay the salary of my workers if they get ill. And that is no problem. But I also have to keep on paying them, even if they can't work because of own decisions. And that can last two complete years. So, if one of those guys crashes his car with 200 km/h during holidays, I end up paying for his treatment, including two years of salary.... think about Skiing, Bungeejumping, etc... awww.
Well, this one you deserve, since this one gives the right benefits to the right side(keeps you from going evil). Especially with all those Enron/WorldCom scandals, those executive parachutes would be shot down by the workers who got shafted before the creditors get a bite.
It just makes you (and us) outsource everything to places where the law is a bit more normal.
I guess youlike slave labor and/or like working for them. No thanks, I'll choose saner companies (yes, that I stands for International, but they dont pride themselves in it)service over some company who gloats about sends off work to these bozos. And if no job is god given, it's going to take a real axe to the board room to stop the insanity you suggest. Yes, a real axe, and yes, Virginia, heads will roll, with careers following suit. -

Re:Some tech background on the 441 setup
Since I'm technically a contractor for this project, the responsible thing would be to say that from a 441 perspective I work for HP. Contractually I cannot disclose the company I work for, although I can say that it's the largest Linux-based company in South Africa. The official and only page for the 441 system is the one given in the original post in this thread by Kracs: http://h40058.www4.hp.com/products/desktops/441/p
r od_info.html -
Some tech background on the 441 setupHi all,
I'm the tech lead on the HP 441 development team in South Africa. Here is some background info on what has gone into it and where HP is going with this.
Firstly, it's extremely similar to the Brazilian effort (which is totally based on Backstreet Ruby, which is a multi-headed solution that has been around for more than 2 years now), and has been designed with the same basic ideas in mind. Both South Africa and Brazil can be termed "developing countries", and both countries are most definitely not the poorest in their respective regions. Linux , and Open Source in general, has had quite some time to bed down and influence the local market, so it would make sense that things like these would develop and happen at around the same time.
Why South Africa? Simple answer: HP has one of only two of their iCommunity centers here (url for the SA iCommunity site is http://www.hpicommunity.org.za/), the other one being in India. At the iCommunity they have intensive training programmes for the local residents ranging from job creation, culture preservation right through to computer refurbishment and even computer programming. So, the 441 system has been a logical "extention" to the ideas that they were working on at the time. Needless to say, the HP 441 system are being tested in India as well, although India has it's own challenges for such a project (over 200 official languages, go figure...).
One major item that puts the HP 441 system apart from similar efforts is work that has been done in the USB device department. As you know, the system consists of 1X AGP (using PS/2 k/b and mouse) and 3X PCI (each with it's own USB k/b and mouse). With the 441 system we have added the capability for each user having their individual sound card as well, so that they can listen to their own audio. Each user also have access to their own USB Disk-On-Key devices, ensuring privacy of personal files and so forth. Apart from this it is pretty much the same thing as done by the Uni in Brazil.
A last comment, this time on HP's commitment to Linux and Open Source in general: I'm not an HP employee, so this is not a "shameless plug". I'm employed by another company who has been contracted to help develop the HP 441 system. So far, it has been an absolute blast to work on this project, and under no circumstances can I say that HP was not committed. This product is actually on a massive "tangent" to what they normally do, so they are also in uncharted waters here. However, the commitment that HP employees have shown to us, both from the local HP offices in South Africa as well as from head office in Palo Alto, is nothing short of "absolutely bloody amazing". Let's hope that other large companies like Big Blue and others take notice of how HP pushes Open Source, sometimes at their own expense with no return at all, but doing so to invest in the developing markets. Now that's a "Way To Go" if there ever was one. One may critisize HP on a lot of things, but one thing that you cannot accuse them of is a lack of balls!
:-)Personal thanks to HP for giving me and my team the opportunity to work on this project. If you are interested in more technical info and product propaganda, here is the product page again: http://h40058.www4.hp.com/products/desktops/441/p

Re:Why .NET and not Java?
Multi-Language: Please, they're all the same language designed to look like other languages
Sure, C# and Visual Basic share a lot, but they're the odd ones. See F#, COBOL.NET, Managed Extensions for C++ and the excellent Managed C++ in the works
Java has multi language support to (Jython). This is not a fundamental reason.
Java has poor abstractions, and is based too much on the fallacious "less syntax, more library" principle. Java is the C of managed environments. Sure, you can compile anything into it, but that's just because it's Turing-complete. Must be a lot of fun implementing any useful compiler without delegates and value types
Value Types: Use escape analysis and a better GC. This is a hack so programmers can give hints to a stupid GC.
Value types aren't garbage-collected at all. And they are important for performance and interoperability. Oh, and the
.NET GC does pretty fine, thank you. Whidbey will even let you allocate managed objects on the native heap, and native objects on the managed heap. And you can't do that in C#, this is an uber-geek feature designed for Managed C++, that only further underlines the multi-language and multi-paradigm goal of .NET. Java, in its arrogant engineered "perfection", will never get actually useful stuff like this. Useful how? it gives you a GC heap for free to allocate your own objects on. It lets you use managed objects with the STL, or the excellent Boost. Or use a different GC, like Hans Boehm's, if you don't like .NET's (in fact, the syntax for Managed C++ has been designed with the goal of not conflicting - or even overlapping features - with any of the major C++ frameworks). Without writing a single line of glue code in CGenerics: Where are the C# generics? The version we're using at work doesn't have them.
Whidbey (.NET 2.0). Also previewed in Rotor
Java Generics will arrive first, but be worse off in the beginnnig.
It doesn't matter, because they are a lie. And Java only got them because
.NET didC# language: The only even marginally valid claim. However, the lack of checked exceptions
Microsoft maintains a longeve C++ compiler: they've been there, done that. They never believed in checked exceptions. Nowadays they are mostly agreed with. By all means, look for Herb Sutter's site: like most Microsoft techies with blogs, he gives no-nonsense explanations of all the design choices he's been involved with, and that includes checked exceptions and lack thereof
-
Re:They have
Actually, you can continue to use C/C++ and just use a garbage collector with them. I don't know why more people don't do this. You don't even need to change your code, as Boehm's garbage collector translates malloc() to it's own allocation routine, and free() does nothing.
In fact, even better, if you have Boehm GC installed anywhere on your system you can do this for already compiled programs using LD_PRELOAD.
Just do:
export LD_PRELOAD=/path/to/libgc.so
/path/to/program
and I'm automagically using a garbage-collected runtime for the program, even if it was compiled to use the standard malloc()/free() calls. -
Re:This is not a cd thenI don't think you can trademark an abbreviation...

Re:Um, it's online
I didn't assert that Java was bad. Personal disappointment is certainly my right.
The way you brought it I think most people would interpret it as saying that Java was indeed bad. It would be very different if you would have been disappointed in the benchmark, but this read as Java bashing without good arguments to back it up.
Actually, my "benchmark" was not flawed at all. It did exactly what it was supposed to do.
No, what you purported to show was that 'fair' memory handling would change the result. However, your benchmark does anything but show fair memory handling for Java. Java is supposed to do gc when it is convenient and make the most of available memory. Inherently, that means that it has an advantage for:
- programs where all the objects fit in the allocated memory
- programs where processing is, at least part of the time, non-CPU bound
Of course, there are also disadvantages to gc (and non-performance advantages). Garbage collection makes Java more useful for some uses and less useful for others. Exploring and quantifying these issues intelligently would certainly be interesting.
What my result attempted to prove was that these benchmarks were flawed and that they were purposely hiding java's gc overhead.
The benchmarks are only flawed in that respect if you want to generalize them for 'big' applications where gc will hamper processing (which does not have to be the case). However, it is simply impossible to alter the benchmark to account for all possible gc scenario's. Therefore, the best thing to do is probably to create seperate benchmarks for gc, which you can interpret based on the specifics of the application that you want to build. However, it is unfair to criticize a benchmark for not showing gc overhead when that doesn't have to be an issue in reality (for some kinds of apps).
What my "benchmark" also showed is that java's gc overhead can be significant.
Well duh. That is only surprising if you don't know Java at all.
It also highlighted the fact that since c++'s new and delete operators can be overloaded, a fair comparison would be to make the c++ implementation perform the same collection deferment.
Sure, gc collection libraries exist for c++. That would be so much more meaningful than simply killing Java's performance by doing something Java programmers are told not to do the instant they are introduced to gc.
Take them with a grain of salt but walk away with the lessons learned.
Creating good benchmarks (where the results are accurate and meaningful) is very hard and I'm certainly not able to do so (since it requires you to know every possible way to skew the results, knowledge that few people possess, and a certain attitude). Trust me, you can't do it either, so go easy with the wise old sage stuff.

Re:Does this mean more free apps for the pocket PC
Apps huh? You did enough searching? There's a lot of free apps out there. You just have to do a little googling:

HP Mobile Printing 2.0 for printing from your ppc
Wisbar Advanced, a task switcher
PocketPCsoft.net has a TON of freeware

FWIW, there are garbage collectors for C.

Re:12 C replacement
How about replacing it with the....HP 12 C
