Re:One wonders why Intel didn't do this originally
Because Intel is a hardware company.
Hardware companies solve problems in hardware.
It just never occurred to them :)
HP on the other hand, who was co-designing the Itanium, wrote an emulator called Aries which emulated HP-PA by doing runtime translation, and that worked perfectly, and at about 80% of the normal app speed. Aries was shipped with HP-UX 11i on the orignal Itanium, and is greatly helping people transition from HP-PA machines to Itanium machines without recompiles, and no loss of performance (since Itaniums are usually faster than the PA's).
Apparently, after 10 years of hardware development of a crappy x86 emulator, Intel realized that its easier (and faster!) to do it in software. -
Misleading headlineThe headline is misleading.
Itanium has always had x86 emulation, just before it was done in hardware, and very very slowly. (The Itanium 1, at 800Mhz, ran x86 software at the speed of a 150Mhz pentium or so.)
A story at The Register, here explains that this new software will translate some of the x86 assembly to IA-64 assembly at runtime. (See picture)
This is the same way that HP's Aries works -- which translates HP-PA instructions into IA-64.
That works pretty well actually, delivering about 80% of the nominal speed most of the time. (We've used it a lot during development of HP-UX on Itanium, and actually ran a lot of the system binaries (ls, grep, etc.) on it until they were ported. Worked pretty well!).What they still haven't done is implement something like this in hardware, but efficiently, like Transmeta does -- they translate x86 to a RISC core in hardware, and get really good performance.
But hey, this is Intel we're talking about :) -
Re:Is there a reason...
I would describe it as "they studied", not that "they feared".
Although some accounts of the development of the mouse at apple seem to imply the choice of one button was subjective, articles like the one referenced in this slashdot article seem to state the apple's choice of was the result of testing.When Apple conducted experiments in the late '70s or early '80s, multibutton mice were faster for experienced users, but increased the errors and confusion of inexperenced users. I'm not sure if studies done today would give similar results. The mouse is so commonplace that television comercials for Hewlett Packard use the hypercard's "index finger" mouse pointer to show selection, and children's cartoons like Dora the Explorer emulate the mouse selection metaphor.

If you want Linux support you need the Cisco cardsthe Cisco Aironet 350 802.11b series cards are the best cards that are supported under linux.
Cisco has not only drivers for linux but also their config tools: cisco Aironet 350 linux drivers
Cisco Aironet 5 GHz 54 Mbps Wireless LAN Client Adapter 802.11a cards don't mention linux drivers on the data sheet, but hopefully they will soon.
If you're interested in linux and 802.11 stuff check out linux wlan project and wlan resources for linux

What does this mean for Ximian?
According to HP, Ximian GNOME for HP-UX was developed under a partnership with Ximian Inc.
I'm pretty sure that Ximian doesn't make alot of money by selling Ximian Desktop to end users (I bought it, but most people don't buy, they download for free). Many of Ximian's recent headlines talk about their deals with large companies like HP and Sun. Now that HP is dropping out, will Ximian lose some of the planned contracts?
I hope not. Ximian are some of the best contributors to the Gnome project. -

HP is slowly rotting. We'll clearly see huge layoffs soon. Examples:
In a major bid for PCs recently (1000+ systems) they were 150+% of the lowest bid. So much for what one sales executive said in the press, "we will loose no bids because of price."
Shipping of I2 products started amazingly late.
The ever-diminishing quality of Scanjets. "Oh you mean that you used it a couple of hours a day? They aren't designed for that!", said the help desk. Funny, the old ones were. I'd like those designs updated and then leave the hell alone. And yes, sell parts for the damn things so when the bulb dies we just replace the bulb, not the whole scanner.
Even their own folks admit that the Laserjet 9000 mechanics are awful.
It all adds up to HP management not sticking to their core business, but instead messing around with mergers and other things they don't understand.
I have been hopeing that someone would purchase the corpse of HP calculators and return to the innovation that made them great. They'll have to restart the IR printers and the IO cards. They'll also have to reassemble the team that made the designs things one took months to grow into. Making HP calculators a success would be a delightful proof of concept that Carlie is a by the numbers, not by the ideas manager. HP was made by ideas, not numbers.
Soon Dell+Lexmark will have gotten the costs down, the quality up and the delivered cost per page halved. Then HP will not be able to live off the cash cow that printing and imaging currently is. Then there will be trouble in the core of the business that no amount of MBA money manipulation will be able to fix. Ideas still count in high tech, a thought lost on the HP front office.
Finally, I was very bumbed that Agilent didn't get to keep the HP name. The HP way is still alive over there. HP should have lost the right to have the name of two wonderful engineers in their name when they spun Agilent off. Talk about dumping the date that brought you to the dance!
HP will survive; they have too many bright people and a good portfolio of Intellectual Property. The path to survival is going to get really really ugly and there is little now that can be done to prevent that.

I have just the box for this...
Guess I'll have to put to use our lab DL760 G2 machine. Has 2.5 GB currently, should be able to find another 2.5 gb for it (Raid 5 memory overhead and all).
How well does BSD work with Hyperthreading? The lab box has 4 HT enabled Xeons in it right now, and I could toss in another 4, resulting in 16 virtual CPUs. -
Re:difference from a PC
Open your eyes buddy, times are a changing...hot-swap PCI on "PC" servers has existed for years and works quite reliably.
PCI buses on "PC" servers are far superior to anything from Sun today, max bandwidth from Sun is only 66Mhz/64-bit, most PC servers offer multiple PCI-X buses - 100Mhz/64-bit that are almost twice as fast. Proliant DL760
You can hot-swap memory on "PC" servers for the last year and a half IBM x440 with ChipKill (AKA Raid 1 Memory)...better than anyone else out there.
And scaleability goes to 32-way for 32-bit ES7000and 64-way for Intel Itanium Altix 3000
As for hot swapping CPUs...god luck on a Sun server, technically you could make it work...practically it's useless today. You have to stop your apps (that's great for HA isn't it?) shrink your domain (if it's bigger then 4 CPUs) isolate the faulty CPU, swap it, resize the domain...then (this is the critical part) restart all you apps so that they recognize the newly added CPU and memory...again technically it works, practically speaking just because the OS is still alive doesn't really matter...no 3rd party apps can cope with this fudging with their memory and CPUs...
The only systems out there that can truly cope with this type of activity are mainframes and Tandem / NonStop solutions... -
Got a HP LaserJet that is multifeeding?

yeah, its free.. good to see some responsability taken! -
Re:proud pronto owner
"Now there's alot of people saying "use a palmpilot" but they don't know what they're talking about. The palmpilot and the like's IR transmitter simply isn't powerful enough to work as remote control. Think about it. If it says it can send files from up to a meter away, what makes you think that it's going to be able to control your television at 4 meters?"
the new Ipaq's (not just the 5450 but some 3900 series, and i believe a 3800 series too) have consumer grade IR, and come with Nevo from universal electronics, They work Really well, but you are also giving up your PDA to use as a remote -
What timing!
Ive been looking for a remote just like the high end pronto
Color
Cheaper
Programmable by that I mean I can move everything around to my liking, not just a learning remote.
Easy for those in my household that arent to tech savvy to be able to use without being overwhelmed
The last three being the most important. ya ya i know choose 2, but there are oodles of the choose 2 variety that just dont cut it
Does anyone know of any roll yer own solutions?
I have tried the sony and it worked but it was choose 2 (cheaper, and easy to use), and I used my Ipaq 5450, but while having 3 of the 4 qualifications (programmable, easy to use and color) I found that since it is also my PDA the others in my house didnt like the fact that I had the remote with me all the time.
Any suggestions -

Re:Ejecting my LaserJet
You are not alone for the paper feed problem. There was a class-action suit against HP because of this. As part of the settlement, HP provides a owner-installed kit to fix the problem free of charge. See this link. I installed it and it did fix the problem.
-
Re:more info than you probably wanted
Actually, if you own a Laserjet 5L, 6L, 3100, 3150,or 1100, and it developed paper feed jam, you could order those 'rubber' fix from HP free of charge (no shipping charge as well). See this link. The only catch is you have to read the instructions and install the fix yourself. I ordered and installed the fix for my LJ 6L. It did fix the problem (most of the time). However, you only have one chance to install it right. If you screw it up, you really need a HP technician to undo the damage. This freebie is the result of the class action of the unsatisfied owners the aforementioned printers.

Re:You get what you pay forYou might want to pick up an HP Laserjet now.
Officemax has the HP Laserjet 1200 as an end-of-life product that's selling for $199. If they're out, just go to or order from Staples. They'll price match it for you plus give you 10% of the difference which would make it $179. Just got one myself. Not a bad price at all. It's end-of-life because it's being replaced by the Laserjet 1300. And the cartridges aren't too bad either.
It's got PostScript Level 2 emulation and 45 scalable fonts plus 35 PostScript fonts built-in. Should be fine.

No problems here
My HP 722c has been going strong for ~4 years now. So long as I can keep finding new ink for it, I can't see getting rid of it.
I do like the gadget factor of the newer models that can print photos right off of a memory stick, though. -
Re:A trojan for DRMAnd imagine that you can already boot Linux off an EFI PC.
Oh, you did know that, right? You can download ELILO straight off Intel's EFI section. (An observant reader will notice that it's actually hosted by HP's research lab, although I can't actually find the info there.)
Of course, you can also read about EFI and Linux from RedHat.
I wouldn't worry, somehow. Plus EFI is mostly used with the new Itanium architecture. I'm sure Linux will be able to survive the impending DRM apocolypse.

Re:the x86 is at a dead end
I agree with the OP that the x86 architecture is probably limited by it's high degree of backward compatibility. I don't have technical facts to back this up, but I think common-sense would agree with me here.
Well, yes and no. How about I quote an article that vaguely touches on the matter? Here's a random article that came up when I searched for "microinstructions x86". It somewhat explains the issues (though the author doesn't seem to understand that floating point registers, MMX registers, and SSE registers are all general purpose registers for most purposes).
Ah, but my point. The x86 is natively CISC (Complex Instruciton Set Computer) which means instructions have variable length and variable arguments. (Of course, SSE and MMX are both SIMD and have instructions varrying from 2 to 5 bytes long, so they're working against the whole RISC idea, but they've got their own special units.) Meanwhile, the SPARC is RISC based. In short, it's easier to make a RISC processor run faster. But that might not matter so much.
x86 implementation of the present day is essentially a RISC processor on the back end. The native CISC instructions are transformed into micro-instructions. This transformation is done in a decoder. So long as that transformation can be done quickly and the micro-instructions well pipelined, the decoder unit shouldn't be too much of a killer.
Having said that, it's worth mentioning some of the strange things that the decoder has to dedicate silicon to. Some trouble instructions are problematic in more than one way, as noted previously with plex86, PUSHF which pushes the current CPU flags (e.g. interrupt flag (enabled/disabled), zero flag (last comparison equal/last sub result in a zero)) onto the stack is problematic. Then there are others which are just a bad idea. PUSHA is an old instruction which pushes all of the 386 general purpose registers on to the stack (including (E)SP, even though it's ignored when POPA is called). These instructions are those sort of useless instructions which came from the philosophy that computers should, on the lower level, start to emulate the higher level languages they're normally programmed in. That idea didn't pan out, especially as RISC became clearly superior. Another similar strangeness is found in XLATB which I haven't seen used in my natural life by a human nor a compiler, but is still supported in modern CPUs. That's not even to get into BCD instructions...
As it stands, though, last I checked what most hurt computer performance in real situations are cache misses and branch mispredictions. I have seen HP make a processor that was completely backwards incompatible that solved this problem. That is, it forced you to recompile all of your old code. It packed instructions around every branch which indicated the full length of both paths. Then both paths could be evaluated at a low cost, and the results of the untaken path thrown away. Other similar things were done to increase the success of cache prefetch and whatnot. Server only, of course -- no one wants a non-backwards compatible processor on their desktop.
But, back to the article which is about new instructions which will improve some processing intensive applications. However, the article notes, problems with branch misprediction are not solved in the new Intel chip. The processor will be clocked faster (and hence, so will the cache) so the problem may be a bit less noticable.
But therein is the

Re:Call Ashcroft!
I am not answering you in the thread where I read your post, because I'm moderating that thread. So, go buy a new Alpha here
The company has government contracts that say it must produce the alpha untill 2006. It is alive and well. In fact it is 10% faster than HP's Itanium offering, the superdome line of servers.
Since HP's intent is to comply with the government contract but not reduce sales of their high margin, larger investment and similar contract with intel Itanium systems, they are not advertising it, posting benchmarks or supporting it (theoreticly they are supporting the hardware mut their support for TRU-64 is minnimal at best).
Prices of the 8 processors at 1224 mhz w/256 GB of ram start at 1/4 million dollars. The DS20E is a desktop workstation running dual 833mhz EV 68 processors.
The 8p version will finish a seti@home work unit every 4 minutes.

Re:Hrmmm... my thoughts tooI was wondering the same thing, because, sandstorms provide stealth for the opposition particularly iRaqis I would imagine.. If all the troops or a recon just relied on this he wouldn't be able to see the enemy pointing a bazooka straight at him.
I also don't see much of the devlopment phase for this. Aren't real time Satellite images already availible? Isn't an iPaq strong enough to decode/decipher/function for this purpose? And aren't the Olympus EyeTrek Glassessmall enough for such a purpose?

That HP Media Center Box...... sounds like a stripped down version of the HP de100c, (PDF manual) which, although it is no longer sold, does run linux, and is a neat little hackable box.
I think the DEC had the potential to be a really great product. Seems like it got lost somewhere in the merger... plus, when it was released a couple of years ago it was priced way out of the market. Damn shame.

Re:Dells line is too much for an ink jet
> I bought my HP laserjet for $240. About the $289 dollar inkjet from Dell. Inkhet printers are typically $200-$100.
I would say about $150 for a decent one. You're not going to print photos with your laser (something a lot of consumers look for in a printer). Also, most consumer balk at the cost of toner compared to ink cartidges.
> After switching to laser I will never go back. I do not need color for most documents and the quality and reliablity are so much better.
I prefer laser prints, too, but I bet you can find some near-laser quality inkjets at your local superstore.
> My epson inkjet blows goatballs and always jams.
If you buy a shitty printer, you get shitty results. There are good inkjets out there, although each varies greatly depending on your needs. Mostly photos? Epson 825 or 925. Mostly documents? Get a Samsung laser for home or decent HP laser for office. Mostly color documents? I would go with the HP 7150 at home or the 6122 in the office.
The Epson 825 has stunning color photo prints and has a 5-color print built in. I don't think the cartridges are that bad either, unless you do a lot of color document printing (instead of photos), the you'll burn through the 3-color fast and waste the photo cyan and magenta. However, if you're doing a lot of color documents, go with a printer with separate photo ink tanks. Get a 825 or 925 if you're serious about photos.

hp's new Digital Media Reciever is similar
hp has a Digital Media Reciever that sits on a wifi network and scans the network for shared folders with music, AND pictures. Then, it plugs into a stereo/tv using s-video and rca cables. It seems to me that this whole phillips stereo is just another version of the same things you can already do with a computer and the hp DMR.
For the record, I do acknowledge that the DMR is SERIOUSLY lacking in that it can't do video. When they support DivX, I'm all for it. -

Coincidence! Here's what I've found...We're in the middle of rolling out two new HP/Compaq DL380 servers, and have run into the same problem as you.
There are a variety of agents and monitoring tools that make up the Insight Management toolset. We've found that some of the tools are better than others.
Pretty much the only *essential* tool that's required is the cpqhealth drivers and daemons. This poll the health of the onboard systems such as fans, CPUs, disk arrays, etc, and will log to syslog when there is a fault. Unforunately, the open source lm_sensors and cpqarrayd packages don't talk to the hardware in the new G3 DL380's, so cpqhealth is your only option. You can find it on HP's support site, as part of the hpasm package for Linux... I grabbed my copy for RedHat 7.3 from here.
cpqhealth comes with pre-built modules for RedHat 7.3, 8.0 and a few other distros (SuSE for example). But I've found that even the most up to date stuff from HP's site only supports the kernels shipped on the RedHat cd, and nothing newer. Luckily, cpqhealth (part of the hpasm package) does allow you to build new modules. You'll need a compiler on the machine. Take a peek at this script:
/opt/compaq/cpqhealth/custom_cpqhealth.sh - it will build a new cpqhealth RPM for you, containing the drivers and daemons necessary to log hardware faults to the syslog (as well as to take action on them).The script will break when you first run it - it will look for the following two files:
/opt/compaq/cpqhealth/cpqasm/S10cpqasm /opt/compaq/cpqhealth/hpuidBoth of which are missing in the most recent hpasm release. Create the S10cpqasm file yourself (it's just a startup script that gets dumped
/etc/init.d - a simple touch of that file is fine for now - you can put a proper one together later), and copy hpuid from /bin (where it gets installed when you installed the hpasm RPM).Once done, you'll have an RPM that installs the following:
two kernel modules: cpqasm.o, cpqevt.o
two daemons:
/opt/compaq/cpqhealth/cpqasm/casmd /opt/compaq/cpqhealth/cpqevt/cevtdMake sure the kernel modules and daemons get loaded, and you'll now get warnings when a fan fails, disk in the RAID array dies, etc.
Even better - unlike the rest of the HP/Compaq Insight stuff, this doesn't use SNMP, doesn't install a web server that listens to 0.0.0.0, and seems to work quite well.
Other annoying things I've discovered about the rest of the HP/Compaq toolset:
- Dumb OS-detection routines - the Storage Monitor Agent greps
/etc/issue for "RedHat" + "7.3"... - Over-reliance on SNMP.
- Unclear documentation - the agents indicate they'll work with the snmpd shipped with RedHat, whereas HPs site indicates you need to install the HP-modded snmpd.
- Corporate schizophrenia - some daemons called hpxxxx, others called cpqxxxx
... some scripts fail, looking for the old filename (HP renamed Compaq daemons, forgot to update script). - Check ports 2301 and 2381 - One or more of the agents installs webservers there, for "remote management". They listen to 0.0.0.0 and have no IP-filtering ability. So make sure that it's firewalled off. netstat -anp is your friend.
In the end, we just ended up installing cpqhealth on the boxes to warn us of hardware problems, and will use RRDtool for our other monitoring requirements.

Re:I Got One...
Sounds to me like someone decided to save a bit of money by not buying the Online JFS package.
It's under $2k per CPU - not bad when you look at the price of the hardware.
Of course if you have online JFS you probably also want mirrordisk/ux which is another $1k per CPU.
But, if you are using Service Guard, you already have both of these, and probably went for the Mission Critical Operating Enviroment package that has all of the optional packages (online JFS, mirrordisk, service guard, EMS, glance+, etc..) bundled with it for a mere $10k per CPU.
If you're spending a million+ on hardware for one server, a couple of hundred thousand for the OS is not that much more. -

SSI
I'd love to see a Single System Image cluster like TruCluster and a good clustering file system to support it. There is work in progress, but there is alot left to make it shine like TruCluster.
Ohh, it would be great if evms supported OpenGFS. -
report about big UN*X features
DH Brown has a _very good_ report about 2002 UNIX function review report. -
advanced filesytem toolsI don't know if there are tools to do this on Linux or not, but the ability to effectively add and remove raidsets to filesystems on the fly, and have the filesystem recognize that it just got larger or smaller while mounted and files are open, is very nice indeed. This is possible using the advfs tools on Tru64 at least; maybe others. What is *really cool* is that if a file is on a disk that you are removing, the OS will move that file to another disk in the domain on the fly, even if it is open! To me, this is truly powerful.
No debate on the merits of commercial UNIX vs. Linux would be complete however if someone doesn't mention the kick-ass software RAID driver "md" that Linux has. Does any other UNIX have software raid that is this complete? I would certainly consider this a "high-end" feature.

Re:MS and hardware platforms / anti-MS biasThe HP/Compaq in particular is getting raves from the real-world usability angle. Never mind a Transmeta-based system might do the job even better and be Linux-compatible - why was MS allowed to be first to (mass) market?
Uh, I know this isn't your main point, but the HP Tablet PC *is* a Transmeta-based system, specifically a Crusoe 5800.

Re:Get some real hardware support
i manage around a hundred remote compaq servers, and every single one of them has a remote insight board installed. it gives you remote key/mouse/video through any java enabled browser. it has it's own network interface and power supply, so it works even when the host system is powered off or completely broken. you wouldn't want to play quake through the thing, but slapping one of these in your boxes means you'll probably never have to physically touch that system again except for hardware replacements.

Whats The Problem?I fail to see what the problem is. Most of the public doesn't care in the slightest about stuff like this, so they won't take any action. Us geeks know what to do to prevent stuff like this from getting out. For example, you can start by using the Corporate Edition of XP, which doesn't require activation (if this bothers your ethics, go buy a copy of XP Home and toss it out before doing this.) Then simply don't use Windows Update..few of the updates are actually necessary (if your system is well firewalled and you run quality non-MS software on top of their OS), and many can be gotten elsewhere.
Finally and most importantly, run ZoneAlarm. This makes it extremely easy to stop hidden windows components from phoning home, and you might just be surprised when you find out what else it's stopping. For example, my HP keyboard driver was trying to contact HP for god-knows-what-reason.
