[opensuse] Why is RasPi worth more effort than older PCs? or Macs?
I've always advocated reusing computers & I've been continually frustrated by the Linux community as a whole recently because they keep pushing software that takes more resources. Linux was always held up as the poster child for keeping alive older hardware, but that seems to have fallen by the wayside. Then something like the underpowered Raspberry Pi comes out & people fall all over themselves to add support for it. For not much more than the cost of a RPi, I can pick up a cheap Pentium 3 laptop off eBay, which would have same as or more RAM(The RPi originally only came with 26MB, but 512MB is now standard), better expansion & have basically a whole computer that's better supported and much faster(I doubt that the armv6 core in the RPi is faster than a P3/500 at most things). As an example, my Thinkpad A30p has a 1.2Ghz P3, 1GB RAM, Radeon 7000/32MB, 320GB HD, DVD Burner. But, with a well known and well supported old graphics chip, even KDE3/TDE is barely usable & KDE4 is like molasses. Granted, the RPi does have a video chip capable of decoding x264, but a 2D desktop like KDE3/TDE should function well on pretty much any hardware. Supporting ARM is a real pain because there are so many different SoC versions, where x86 is a known and well supported standard. I'm not against supporting the RPi, I just don't understand why it, being underpowered is considered "acceptable" where older PC hardware isn't & people are told they should buy newer. Just wondering. Thanx -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

For 35 bucks you get a whole computer with the Pi. For about $65 you get a bunch of auxiliary features like a power supply case, cables etc, that you really don't need. But the $35 price includes every thing you really need, including a fully capable linux distro (three of them actually, as well as BSD). Up and running in 15 minutes, and, sporting the same processor as the Iphone 3Gs, it is no slouch in performance. The Arduino by comparison is bereft of physical ports, even when you buy the $74 dollar version (seemingly always out of stock), dramatically slower, still wide less capable than the Pi by a wide margin. And the distro(s) available for Pi are largely complete, Debian linux, which every interested 7th grader can manage But most importantly it WORKS OUT OF THE BOX. Why? Because it is capable enough to warrant the development. It has all experimental capabilities bolted on AFTER the fact, rather than as the principal raison d'etre. So the kid can blink silly the LEDs on the auxiliary breadboard kits and build the robots etc, but the basic computer is capable all by it self of handling real world loads. And supporting the ARM processor is NOT harder than supporting the multiple versions of Intel concurrently available. Its essentially no harder than a recompile of the distro with different switches. The problem isn't with the PI, its with YOUR expectations. You expect the ThinkPad to handle modern workstation loads and Bloated desktop environments. Why? Well it LOOKS just about like the machines that DO handle that load. But the P3 was releases almost a DECADE prior to the Raspberry PI processor. The Pi? Nobody expects to put KDE on that, they expect to run at the command line (although it has a Graphical User Interface if you want).

Not really. I understands that he complains that Linux is abandoning that target. Not that those laptops can not cope, but that Linux desktops are becoming more and more demanding, needing recent hardware and abandoning older hardware.

Surely there are other, minimalist, less demanding distributions and desktops? Surely the OP doesn't have to use KDE or Gnome.

Well, related to that, there are several people that are coming to the forums with a common interest: they are expatriates from Windows XP (Xp goes out of support in 2014), seeking someway to keep using their same computer with something else. And considering openSUSE. If they can not succeed to make it work, they may go to another distribution, or going back to Windows. We have now an opportunity to win a bunch of new users to us. And years ago, one of Linux advantages was precissely being able to run on older hardware, contrary to Windows requiring hardware upgrades on each version upgrade. Has openSUSE abandoned this goal?

The machines I pull out of the Closet of Anxieties are old W/98 and W/XP machines with an 800MHz single core CPU and 512M or 1G of memory and a 20G or 40G drive. I test them with Knoppix/KDE Live but all the ones that work and have 1G of memory run openSuse 12.3 and LXDE or XFCE. It loads on a 20G drive. I haven't been able to get it to install with only 512M of memory, but a disk installed on a 'larger' machine will run on a 512M machine. It doesn't do well in GUI mode but if you want a firewall or a DNS/DHCP server or similar, then the 512M model is OK. I've also taken one of the 1G memory models and dropped a half-T drive in it to do NFS/SAMBA and the Windows users on the LAN were quite happy with it as an archive. I'm sure I could use one, or even share one to do same web server, a 'departmental wiki'. I tried a Fedora-19 USB stick in one but there was a problem with the graphics. I didn't waste time trying to find out the reason as it ran openSuse 12.3 OK. -- How long did the whining go on when KDE2 went on KDE3? The only universal constant is change.

Really? Debian is far from considered user friendly. uBuntu is but not Debian.
For one thing I fail to see exactly why these new desktops NEED so much more processing power. Eye Candy? Bling? Desktop Search tools that I & the MAJORITY of computer users don't use? I don't NEED a 3D desktop. However, the fact that my A30p has 2 DVD drive bays & that I can put a 1TB SATA in 1 or both and/or a DVD Burner & use it as a mobile server make it VERY useful to ME. No other newer machine has 2 DVD bays that I have found. Plus it's 1600x1200 IPS LCD is much better than most newer 1366x768 displays by far even being 13 years old. But that wasn't the point. My question was why do people fall over themselves for a machine that you can't upgrade the RAM, but people with machines with 512MB are told to upgrade or replace the machine because 13.1 requires 1GB RAM. What are we doing that's so much different from 5 years ago that we NEED twice the RAM? Other than using 50+ tabs in Firefox, I can't find anything in top that shows that much more RAM usage than what I was doing 5 years ago on a Dual P3/500Mhz with 512MB RAM. Sure the extra Ghz is nice for loading some web stuff, but the Pi can't be that good at displaying web pages. Can you run Flashplayer on it to watch youtube videos?(I don't know, I don't have one). That's what my son does on-line more than anything else.
But the P3 was releases almost a DECADE prior to the RaspberryPI processor.
So what? The Tualatin P3 1.4Ghz outperformed the P4 until it was past 2.4Ghz in MANY things. Then, the Pentium M was released based on the Tualatin P3. The current Core i series trace their roots to the P3. Granted my Core2 based T60p is now my main machine(mainly because it's lighter) but I still use the A30p for watching movies and doing onsite backups so it's not like I should throw it away.

I'm not against the Pi as a learning machine. I just don't understand why it, being so underpowered is ok to play with, but if you want to use a real machine you are told that anything less than a Core2 with 8GB RAM is too underpowered to do any real work on. The Pi is far faster than my Powerbook 3400 with it's 240Mhz G3, but then again, it only gets used occasionally for writing. I have Clasilla on it, which is a continuation of Mozilla for Mac OS 9, & I can go online with it but you can't expect much from it with only 144MB RAM. A programmer once told me that he wrote to use all abvailable resources whether they were needed or not. Back barely 15-20 years ago, there was no choice but to optimize code. Now, it seems like no one is optimizing code but just churning out programs. Why waste time making programs leaner & more stable when we need to add all these new nifty features that most people never use.

It is precisely the definition of "day to day" task that is critical in this branch of this discussion. Recently, I spend my time developing web applications, and the ideal target is to have my api respond to the client in under a second, though the average, including the round trip to web services my api uses, is more like 6 seconds. While an order of magnitude slower than the ideal, it remains acceptable as my competition typically averages about 20 seconds. I need not explain to most here what factors impinge on improving the responsiveness of a website, but suffice it to say, neither older machines nor entry level current machines will perform adequately IN THIS CONTEXT. I also have programs that handle batch processing of accounting data, and these take a couple days to finish. Again, these are programs you want to run on the fastest machines you can afford. In other contracts, I dealt with risk assessment models related to environmental management. In that area, it is not unusual for a useful model in that discipline to require half a million lines of highly optimized C++ code or more. And then, after many hours of compilation, the model itself may require anywhere from a day or two to a couple weeks, depending on the details of the problem. The day to day tasks of the scientists, engineers and programmers require working with such applications; and their time isn't inexpensive. They are not the kind of staff you want sitting on their thumbs waiting for their computers to finish their task. On the other hand, I have developed embedded software, in what seems like another life, and with the sort of embedded software I worked on, a tiny footprint for the OS and application code is a priority, without sacrificing capability. And on yet another hand, if one has a number of admin assistants, each using only the usual office software, the speed with which they can do their jobs is dependant on the capability of their hardware and software. Making them use older hardware, and less capable software, can slow them down significantly, making them less efficient. I'll leave it to the accounting types out there to compute the cost/benefit tradeoffs between newer, faster, hardware vs a 5% improvement in admin efficiency (it would be as idiotic to put a super computer on each admin's desk as it would be to put an old 8080 PC running DOS there). I am sure there are people out there actually doing that kind of calculation to determine when to replace older computers for businesses of different sizes. The costs associated with staff waiting on their computers can be significant. As an aside, here, I would point ot that to simply describe tasks as "web browsing, word proc, or email" is misleading. The way I browse the web now is very different, demanding a lot more of my system, than I did even 5 years ago and neither the hardware nor the software I used back then would be able to handle what I do now. Similarly, while I do not do a lot of word processing (known, when I was young, as writing), what I do now is significantly different from what I did years ago. I do more with my word processor now, just because I can, and that is just because the software supports it and the hardware is able to run it. And I would point out that what is true of me in my limited writing, is even more true of, say, admin assistants, who are able to do more, more impressively, because the software they're using supports their efforts and creativity. But, in a sense, all this discusson of day to day tasks, and the contexts in which each of us find ourselves, is beside the point. This is open source software, and a portion of the community decided it was interested in developing support for RasPi, and went ahead and did it (or are continuing to do it - I haven't followed that much). If it is true that more effort is being put into supporting RasPi than older computers, that is probably a reflection of the numbers of people who are interested in each. It seems to me that if the question is honest, one is interested in understanding why there are so many more people interested in RasPI than old PCs. If it is not so honest, it carries an implication that those who are more interested in RasPI than old PCs are somehow wrong; and that smells of arrogance. The question of what people are interested in is a value judgement, and I see no basis for passing judgement on value judgements, any more than I would accept an adverse judgement on my taste for rib-eye steak or than I would pass adverse judgement on those who mysteriously prefer salmon.

To me, the RPI (and derivitaves, like the UDOO, Beaglebone Black, etc.) aren't about the computer hardware. They're more about what you can do with them - interact easily with sensors, control outputs, create robotics projects, stuff like that.

But it just seems odd to turn around and badmouth the Raspberry in the same post when it is the living proof you can still do many useful things in a small machine. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

My intention wasn't to badmouth the RPi. It was to ask why something so underpowered gets so much attention when there are perfectly capable machines out there that really should be more usable other than the demands of the newest versions of everything. Quite honestly, the only reason I have a 6core Phenom II in my desktop/server is for video encoding. I don't play games, edit video or anything else. Other than web browsing & checking email(which I do in webapps & have for 15+years) I don't really do anything different now than I did 10 years ago. Don't get me wrong. I used to run OS/2 & would run win16 programs in their own session so yes, that takes more resources. I also have Virtualbox installed on both my Thinkpads & my server. Until recently the P3 had win200 but now it has XP, & it works fine for what I need it to do. Sure the Core2 is more responsive but after dealing with slow computers for 30 years, having to wait isn't an issue for me. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

BECOZ ITZ KY00T! I can has Piz now? Seriously, though, I think that its tiny form factor is a big plus and helps set the expectations of those who want to play with it. I'd love to have a bunch of them in air ducts controlling flow, running around on spider legs patrolling the house and playing with the cats, and so on. Try putting legs on a laptop and see how it goes ;-) On the other hand, if you're after a compute server farm and need RAM for processing and crunching, a stack of old laptops goes a long way for that purpose. And if you want a storage farm, a single 14-bay tower and big power supply goes a long way for *that* purpose. It's all about setting expectations, and in addition to being new and cute and fun, the Pi's small form, low power draw, open structure, and simplicity help it fill a lot of niches. Speaking personally, I would be most interested in something that can interface wirelessly with keyboard, mouse, and screen (remote display on an Android tablet, maybe?) via Bluetooth and has WiFi & RFID, whether it has removable uSD storage or some permanent store on board. Build me one that's about 1" x 2" x .5" and runs for a day on a flat battery such as in a cell phone and I'll finally be ready to cough up my own money :-) Happy New Year :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt

Depends on what you want and need. If you don't want/need all the fancy UI elements that KDE or GNOME provide, then it actually runs pretty well. I'm speaking as someone who's running both openELEC and openSUSE 13.1 on a RPi.
Well, if you want to pick up a cheap laptop, do so - the RPi port is a community project, and is something that community members have decided to work on. There's no commercial (read: SUSE) interest in the port at all. I find the current 13.1 image to be pretty snappy, actually. I've got it running e17, and it's quite usable. I paid about $100 for my total kit (including case, power supply, wireless-N adapter, sdcard, breadboard, gpio cable, and a few electronic components). openSUSE is on a 32 GB microsd card that I bought for my tablet to run Cyanogen on, but the card wasn't actually capable (higher power requirement than the tablet provides, apparently), so I got one that was compatible and had this one kicking around. NFS for disk storage on my existing systems. HDMI out connected to the projector in our TV room. Mine runs on a 10' screen, no monitor purchase required. It's not a question of it being worth more effort, it's a question of "this is what a certain group of people are interested in doing, so they're doing it." That's what a community distribution does: People are interested in making it work and are putting the time into it. You want to support an older laptop? Go ahead, nothing's stopping you from organizing like-minded individuals and making it happen. :) Jim -- Jim Henderson Please keep on-topic replies on the list so everyone benefits -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

For 35 bucks you get a whole computer with the Pi. For about $65 you get a bunch of auxiliary features like a power supply case, cables etc, that you really don't need. But the $35 price includes every thing you really need, including a fully capable linux distro (three of them actually, as well as BSD). Up and running in 15 minutes, and, sporting the same processor as the Iphone 3Gs, it is no slouch in performance. The Arduino by comparison is bereft of physical ports, even when you buy the $74 dollar version (seemingly always out of stock), dramatically slower, still wide less capable than the Pi by a wide margin. And the distro(s) available for Pi are largely complete, Debian linux, which every interested 7th grader can manage But most importantly it WORKS OUT OF THE BOX. Why? Because it is capable enough to warrant the development. It has all experimental capabilities bolted on AFTER the fact, rather than as the principal raison d'etre. So the kid can blink silly the LEDs on the auxiliary breadboard kits and build the robots etc, but the basic computer is capable all by it self of handling real world loads. And supporting the ARM processor is NOT harder than supporting the multiple versions of Intel concurrently available. Its essentially no harder than a recompile of the distro with different switches. The problem isn't with the PI, its with YOUR expectations. You expect the ThinkPad to handle modern workstation loads and Bloated desktop environments. Why? Well it LOOKS just about like the machines that DO handle that load. But the P3 was releases almost a DECADE prior to the Raspberry PI processor. The Pi? Nobody expects to put KDE on that, they expect to run at the command line (although it has a Graphical User Interface if you want). It has a better chance of running KDE than that your P3. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
