Talk to the IBM Linux Hackers 245

Posted by Roblimo
from the billion-dollar-men-and-women dept.
We've all heard plenty about IBM's investment in Linux, but we don't hear much from -- or about -- the actual Linux developers at IBM. This interview is not with one person, but with a number of IBM Linux people spearheaded by Dave Hansen, who volunteered to help us with this interview. Of the group responding to your questions, Dave says, "There are more people, but the majority of the group's skills are represented. No surprise that we'll have our responses reviewed before we send them back to you, but we'll try to expedite that.
"A little background: The group's experience is pretty broad. Most members were Sequent employees who worked on Dynix/PTX before IBM acquired Sequent (we are still mostly based in Beaverton, OR). Not everyone was with Sequent; Matt Dobson and Dave Hansen came into the group last summer, right out of college. A few of our Austin colleagues are long time IBM employees who worked on the AIX kernel before moving to Linux. Ask about anything from the rmap VM, to PTX's crashdump facilities, to life in Portland :) As usual, please ask only one question per post. We'll forward 10 of the highest moderated questions to Dave, and run all the answers, verbatim, as soon as we get them back.

        I'm a developer for AIX. I can tell you there is NO sharing of source between the two areas. AIX is the old proprietary world of software engineering. The licenses are your typical "if you copy that floppy you're a BAD BAD person...". I know people in the LTC and none of them have read access to the AIX source repository. IBM is as paranoid of the GPL as Microsoft is. Since I do device driver work, I'm not even allowed to look at the Linux kernel source.

        There's a pretty large (virtual) fence between the AIX and Linux hackers. That doesn't stop IBM from trying to get AIXisms into Linux (read JFS and powerpc optimizations).

        If the economy wasn't so damn bad I'd have transferred over to the LTC long ago...

      I haven't heard any statistics about any recent changes, but I think if the number of women in this industry is shrinking, it's good evidence that women are smarter than men. They're seeing that engineering is a crappy, under-paid, overly stressful, and exceedingly unstable profession, and are heading for greener pastures. It took me five years of college and a few years in the workforce to figure this out for myself; my hat's off to others who see this sooner.

      Now if the number of women in school for engineering is rising, that's a sign of two possible things: 1) younger women are stupider (and judging from what I see of high-school kids these days, I'm starting to think just this of all kids), or 2) they're getting an engineering degree for its prestige or value in going into some other type of profession later, and have no plans to become corporate drones for EE companies.

    Linux seems to be drifiting, very slightly and relatively slowly now, towards a place where a couple of companies exert a kind of defacto control over it.

    The licenses are still open, but as a practical matter, most of the core development is being done by corporate people that are concentrated in a few companies like RedHat, and to a lesser extent, IBM.

    Do we low end users have cause to worry about this? Does IBM worry about the control that a company like RedHat has over IBM's Linux initiative? And is it really possible, as a pratical matter, for technology as complex as GCC to be forked by volunteers?

    • Debian, Mandrake, Slackware, etc.
      Large companies can create their own distributions, in fact even other large organizations can create their own distributions (NSA for example is working on a high security distribution.) IBM or RedHat have market for their distributions and it does not mean that there is no market for Debian.
    • > And is it really possible, as a pratical matter, for technology as complex as GCC to be forked by volunteers?

      What's the problem here? I've "forked" a number of C compilers in the past. I found myself working on projects that needed a cross-compiler, so I got one
      and recompiled it for the new machine. In the process, I invariably had to make a number of changes. Thus, to aid in debugging, I added a builtin caller() function to several compilers that acted pretty much like perl's function of that name. I've also added in a number of hooks to make the code interoperate with debuggers. This should all qualify as a "fork", since my code was never folded back into the original compiler. And yes, I did such things all by myself.

      Granted, GNU makes things that are bigger and more complex than most others. But I don't think that forking it would be much of a job for one person who knows a bit about compilers. If GNU didn't want something useful folded back in, the result could well be a fork.

    IBM will be using linux to help sell their hardware. Other companies have tried this (VA Linux, which owns Slashdot, once had linux hackers on their payroll). Obviously, IBMs hardware is in a different league as an x86 clone, but do you have any thoughts on Open Source business models and their validity? Once the kernel is running smoothly, will you be disposable since the "Open Source community" can continue development for free?
    • I can partly answer this one, and I'm not one of the Linux developers at IBM.

      IBM's model is only partly to use Linux to sell their hardware. Today's IBM is more of a service company than a hardware company. Their move towards Linux is more because they think (and rightfully so) that they can make money with *service* for Linux, not because Linux will sell a ton of hardware boxes. IBM knows that hardware (except for the highest-end stuff) becomes a commodity over time with little to no margin. Service, however, allows the company to leverage its brand and experience to charge a premium over the local VAR, and thus create a reasonable margin.

      As for IBM's opinion of Open Source business models and their validity, I certainly hope they have a lot of belief in the business model of giving away the software and charging for service... otherwise, they're one confused company.

    IMHO, IBM makes some of the best mobile hardware out there -- one of the professors I support raves about his ThinkPad 600, that went with him into the Israeli desert for several months and is still running strong, no service required -- but the linux support for that hardware has been, um, erratic at best. Yes, we've been occasionally been able to purchase the odd model with linux preinstalled (usually it's *more* expensive than the comparable model with MicroSoft preinstalled, grr) but an awful lot of the hardware (mini-pci modems, &etc) is rather difficult to drive with a penguin behind the wheel. Why does IBM's linux enthusiasm fade so quickly at the small (physical) end of the hardware scale? Is there momentum underway to change this?
    • by vluther (5638)
      Just to clarify, you mean for the older laptops right ? I have had the pleasure of owning an a20p, a22p, and now an a31P, all of them were freed from windows within the first day that I got them. Apart from the modem, everything worked flawlessly.

      This new a31p has a built in wireless card, that was the only thing that needed work, and once I put 2.5.13 on it, even that card worked fine. I used the stock redhat 7.3 CD to install everything. Even X.

      The video card on this laptop is an ATI Mobility Fire GL 7800 (64MB video card), it's supposed to be bad-ass, only Dell ships with a 64MB nvidia to compete with this a31 model btw.

      Apart from the modem, I think IBM's laptops are the greatest mobile machines to install Linux on.

      But aside from that, I agree with the final question. About this time last year, you could find Linux pre-installed on the ibm.com website, hell it was even advertised .. thinkpads with Linux. Was the market really that low ? Or was there pressure from outside forces to sell only MS Laptops ?.
    • I have the ThinkPad 600e. I installed RedHat 7.3 on it, and it works wonderfully. X came up without issue. I run wireless on it at work and home.

      Oh, sound was an issue, but IBM's website tells you how to make it work. It uses the cs4232 driver. The device does not init correctly on boot for some reason, so if you remove then remodprobe the module it works fine.

      I'm unable to suspend to disk, but I didn't set up a partition for that. Haven't seen if Windows will still do it after I repartitioned.

      I'm looking forward to the suspend to RAM functionality of the 2.5 kernel.

      I've been trying to get the serial port to work today without much success. I believe I have the tools required.

      The MWave soft modem driver was released just a bit ago (source and all I believe), I have downloaded the driver, but haven't tried it yet.

      I've gotten DVD working great with mplayer (be sure to use the FFmpeg library). On a P2-400MHz!

      All in all I'm very pleased! I got mine for a song on Ebay.
    • I think part of the probem is that IBM is huge. The left hand doesn't know what the right is doing. The way I understand IBM's structure is that it's not one large, centrally-managed company, but rather a bunch of loosely grouped companies. The VP of mid-range servers might have a woody for Linux, but that doesn't mean the VP of thinkpads has to do anything with Linux.

      What I'd like to know is exactly who in IBM is pushing Linux and what divisions they oversee. The whole s390 Linux thing took me completely by surprise as I had no idea the big iron IBM folks had any interest in Linux; from what I understand, this started as a bunch of s390 engineers messing about with a VM during their lunch hour, but now it seems like it's getting attention from above (which is very cool, but somewhat unexpected for those of us who've been in Corporate America for too long).

      I can't imagine an ebullience of Linux enthusiasm overtaking all ranks of IBM, so I'm guessing there's someone higher-up who's pushing Linux. I'd like to know who these people are and what parts of IBM this affects and does not affect.

      Anyway, it'd be better if someone on slashdot with inside info could answer this question. I don't want to bore these engineers with politics (I'm looking forward to a hardcore technical interview, not some fluff that I can find on cnet or salon).

    As many people here, I am a huge Linux fan, but I am so much so that I am trying to figure out how to get into the professional Linux world when I graduate.

    I attend Clemson University [clemson.edu] and am in the Computer Information System (CS + business) program [clemson.edu] (and doubled in Political Science [clemson.edu]). My goal is to become a Linux sys admin, or perhaps some other Linux guru type job. The work that IBM is doing with Linux is also very appealing to me.

    So, how did you get your job, and what would you recommend as the path to follow for us geeks just getting started in the professional world as to how to get into Linux? How can I become as entrenched with Linux as the professionals at IBM? I have had two internships (not with IBM, nor with Linux, but with other CS stuff), but how can I get an entry-level job in a Linux intensive environment like IBM? How can said job lead me into a career where I can be deeply involved in the Linux world?

    • Check out IBM's Extreme Blue [ibm.com] Internship program. It's a great program and it gives students a chance to work with Linux and other Open Source technologies (as you can probably tell, I am participating in this program this summer so I am evanglizing a bit ;-))

      Aim higher. You don't typically come to IBM to become a sysadmin. I strongly suggest making yourself known to the e-Business Infrastructure group [ibm.com]. Come here if you want to always be at the forefront of "professional grade Linux".

      but how can I get an entry-level job in a Linux intensive environment like IBM?

      I was not a college hire, but we get a fresh new batch every year. I had 7 years of varied IT experience (6 of Linux; most of it personal). Even then it took 3 years to get hired. In '97, e-biz was not ready to embrace Linux, but by 2000 they knew it was the future and were grabbing up as many practitioners as they could find. Now the market is coming at us full bore and it feels a lot like the moments leading up to the first time Jodie Foster heard the transmissions in Contact.

      In e-Business we use the most appropriate tool for the job, so it helps to understand [ibm.com] the 3-tier application infrastructure model, and why IBM releases Linux versions of nearly all of its software on all hardware platforms.

However, historically, IBM attacked the unified UNIX which GNU/Linux is in some ways becoming. As the developers, you are on the front line of IBM's test as a Linux-friendly force. I'd like to ask what efforts you are making to keep this the case.

    In general, the Itanium has seen quite poor adoption rates and even Intel/HP admit that their initial public silicon is really only fit for software developers and platform work (due to low performance, and altready established players in the 64-bit field).

    While meeting with a fellow software consultant recently, I queried him on his plans to expand his business. Specifically, I was curious to know what information infrastruture he plans to grow around. He returned a puzzled look. I had asked if he had considered Linux as a possible server platform, to handle internal source code control, email, and file shares. I suddenly diminished in his eyes. He responded as if I had just asked him if he wanted to buy used Yugo. To him, Linux isn't business worthy... isn't a real stable, capable OS... and worse yet... a threat to the software industry!

    Linux needs positive marketing. So my question is, what can you do to champion Linux with IBM's giant huge marketing machine? Not every IT person in the world reads Slashdot (I'd venture to say less than 1%), but a large number of IT people read MS marketing. So the perception most IT people have about Linux is through a Microsoft lens.

    I want to konw when IBM will begin to support Linux at an OS for it-self instead like an tools for selling hardware.

    IBM never release any desktop tools for Linux. The Lotus SmartSuite never hit the Linux Desktop, nor Notes. By doing this, IBM it's the only company with Microsoft do not port they office suite to Linux.

    The IBM's Lexmark company never provide any driver for the home /SOHO printer (the only Lexmark printer driver was marked experimental at linuxprinting). By doing this, IBM it's the only company in the world do not offer support for there printer to the Linux Home users.

    IBM also dicontinue the support for ViaVoice under Linux!

    IBM also doesn't support they desktop and notebook hardware under Linux or other free OS! IBM even take the FreeBSD partition number to use it for it's "suppend to disk" on the bios of ThinkPad making them unusable for FreeBSD !

    I really think that's IBM only take the Linux part they need now, and don't look at the future.

    The grid computing it's right there at our door, and already desktop begin to replace mainframe in batch processing. We are now using lost cpu cycle do process job under the Windows and Linux desktop. If IBM doesn't investigate this oppurtunity (and the Linux Desktop) in the neer future, IBM will just don't get the next wave and will begin to clash !
    • Sorry !
      My question is :
      To you think IBM will support Linux in an broad manner instead of only on there aging Mainframe ?

      Linux it's not only the kernel, it also the GNU movement and it's also a lot of individual who program it, and program application for it and use it.

      When a company claim to support Linux and in fact they only use it to promote they older and desuet platform, it's a really bad move for my opinion.

  • With high-end pc servers closing the reliability and performance gap, what advantage is their to moving to Linux for S/390?

    A example, widely sited, states that great cost savings can be achieved by consolidating 100's if not 1000's of pc servers. This only works, if the servers being replaced are under extremely low work loads. Many argue that a much greater savings could be achieved in consolidating serives on existing x86 systems.

    The only example that've heard that makes any sense, is using linux to extend the cabilities of Mainframe OS's (i.e. using linux, to run apache to create on-line reports, replacing printouts).

    From the brief bios, and Sequent pedigree, it looks like there is a lot of focus on high-end features like NUMA, async I/O and the like.

    Other commercial organizations, notably SGI, are also putting forth effort in those areas. There is actually quite a bit of overlap.

    Since these are "open source" projects, do you collaborate with your traditional "enemies" such as SGI and Sun on Linux? What is your management's attitude towards that type of collaboration? If not, do you "look" at the work the others are doing in comparison to what you are doing?

    Why isn't IBM making more of an effort to recruit developers directly from the Linux community, as opposed to hiring people who have very little if any working familliarity with the platform?

    Speaking from experience (I worked at Big Blue for about 2 years), the typical new-hire at IBM knows very little about Unix and other core technologies that form the foundation of your company, and its products...I can name several that didn't even know what a network card was, who gained full-time positions as regulars within the company while top-level engineers and other knowledgable employees were getting pink slipped for cost reductions.

    There are employees at IBM who are just now learning what a network card is, while thousands of seasoned Linux developers go unemployed.

    What does IBM plan to do about the experience gap within the company?

    • Why isn't IBM making more of an effort to recruit developers directly from the Linux community, as opposed to hiring people who have very little if any working familliarity with the platform?

      I don't think your question is very fair. IBM has been very active in recruiting people from the Linux community including the Extreme Blue [ibm.com] program which recruits college students who are very active in the Open Source community and gives them a chance to work on Open Source software at IBM. I also know of a number of top open source developers who were hired by IBM to work on important technologies.

      There's always a need for entry level people and I don't think it's fair to ask IBM not to hire these folks. If they didn't, you would simply complain that they don't hire entry level people and therefore, aren't given anyone a chance to develop marketable skills.

    At my job we use AIX boxes as file and application servers at remote sites.

    There are two reasons for this, sysback and the lvm.

    Sysback makes it braindead-simple for a technician in a remote site to restore a server. Pop a tape into the drive, turn the machine on and walk away.

    Combined with the great logical volume manager and smit, AIX is probaly the easiest os to deploy.

    Are there any plans to deploy these tools to the linux platform. This would make it alot easier to move large customers, particularly government to IBM/Linux solutions.

  • I don't think I am alone when I say that IMHO near-perfect, generalized MS Office compatibility would be the biggest boost Linux could receive in the desktop front. Everybody knows what IBM has done to help Linux succeed in the server market, from multi-million ad campaigns to huge contributions on the development effort. Could IBM consider developing a standardized library and API to MS Office file handling, which would enable any Linux app to transparently read/write those formats? This is the sort of thing which unpaid hackers have problems developing (witness the uncoordinated efforts of GNOME, OpenOffice and KDE coders), but would be near-trivial to a professional dev team such as IBM's.

    As an IBMer with a thinkpad, I'd like to ask a very straightforward, down to business question.

    When will I have Linux running on my Thinkpad, supporting my internal IBM needs?

    Seems to me that there will be some initial development cost, perhaps a bit of training, but in the end, a Linux machine would be more easily maintianed. Between exporting xterms, allowing support to telnet or ssh in and needing to be root to really screw stuff up, I think there's a great deal of leverage there. I've looked into the C4EB (Client for E-Business, for those not in IBM speak) stuff, but I can't find out how to run my Lotus 1-2-3, Wordpro, Freelance, etc. (including secure tunneling aka working from home) without kludging it. Certainly, it's fit for some needs, but my job places me in a less flexible position.

    My background: I'm a hardware engineer, been playing with Linux since Slackware 96 (in 1996) as a user and admin. I won't allow an unsupported distribution, like Debian or Slackware, to touch my machine, as so many IBM specific things make assumptions.

    How about a CD (or 4) that I could boot to that could 1) shrink my Win2k partition 2) set aside my hibernate partition so hibernating will stop blowing away my Linux partition 3) install Linux, Gnome or KDE, Wine and integrate Lotus 1-2-3, Wordpro and Freelance. Sure, I could do this on my own, investing the weeks or months that I had when I was a student, but I'm married now and my management won't support a hardware engineer playing with software on that level.

    I think it'd be sweet to be able to hit a shortcut that would export to a bot, signal a telnet or whatever, so an automated script could diagnose simple problems and queue for human review if necessary.

    IBM must have a particular interest in making Linux apps easily deployable across different hardware platforms (x86, PPC, S/390 etc.) But for many Linux users, downloading an x86 binary is much easier than building the app from scratch.

    DotNET will add a major cross-platform capability to Windows apps - there is a risk that this could leave Linux high and dry.

    Is there a specific IBM strategy addressing this problem, e.g.
    • Ensure C/C++ builds are available for each platform
    • Use IBM Java
    • See if Mono or DotGNU take off and adopt one of them
    • Something else?
