1/22 looking to buy a new development laptop
needs ssdrive, >6 hr possible batt life, and runs linux reasonably
Anyone have a recommendation? Thx.
\_ thinkpad t23 w ssdrive and battery inplace of drive bay
\_ Ever wondered what RICHARD STALLMAN uses for a laptop? Well,
wonder no more!
http://config.fsf.org/rms/wiki?name=rms

\_ Apple makes the best laptops, IMO.
\_ always disliked apple laptops. no pageup/down key, too heavy,
have that silly apple light on the back of the display, and
don't offer an extended-life battery as a mfg option --!OP
\_ My MacBook Pro has pageup/down. I find some of the laptops
like the Air to be really light. Battery life also tends
to be pretty good compared to the Dells and ThinkPads I
have owned. I buy new 2 laptops every three years (one
Mac and one PC) and I far prefer the Mac.
\_ real page up/down or fn up/down
\_ and you can run Parallels or VMWare and still get Winblows
and/or Linux, which is really really awesome. Plus, you
don't have to worry about having to reboot your Winblows
every few days. You really get what you pay for.
-20 year PC user, 1 year HAPPY Mac user
\_ why does every mac user say 'run parallels'?
why not just boot to a linux partition? -- !OP
\_ I recommend using a VM, but not Parallels. The reason
is that its far more convenient than booting another
partition. It's much nicer to be able to run both OS
at once.
\_ seconded, but that's because I run both a PC
and Mac and VM images are universal on both.
If I run Parallels, then I'm stuck in Mac OS land
\_ spoken like someone who never ran a VM. I can run
multiple OS's at the same time with only 5-8% penalty
in run-time (if the application isn't graphics oriented
like games). Obviously, if you're playing games, then
you need to run natively. But if you're doing web
or backend development, running OSs in parallel
is a godsend because I depend on apps that exist on
PC (shareware), Mac (Photoshop), and Linux (compiler,
apache, editor)
\_ Not a stranger to VMs, but certainly do not want my
long-uptime linux and freebsd work environments running
on something as unreliable as OS X.
\_ I hope you don't have a raid hooked up to it,
the upgrade from 10.4 to 10.5 hosed my raid.
\_ I run linux on my older ibook. PPC tho. Screw osx
pkg management is crap.
\_ oh wow, ok. America is great! Vote for GWB!!!
\_ I did look at those and they didn't have the battery life
they seem to die out around 4-5 hours of use, and I mean
compiling, debugging, etc. I'd like something that doesn't
die over a long flight (say to EU).
\_ Ok, what PC today lasts 6 hours of compilation?
\_ I get a good 6 hours work done on my current machine:
http://www.csua.org/u/pyp (portege r500, ssdrive)
Been using it fairly heavily day in and day out 16/7
for the last 3 years and the mobo is starting to have
problems recharging the batt. And heh, the keyboard
letters have all worn off.
\_ Get a spare battery. Dell laptops let you use an oversize
battery instead of carrying a spare battery.
\_ yeah oversized and spare batts are the way to go,
i don't think mac supports swapping batteries for
extending life :-(.
\_ You sure can switch batteries. I have three for
my Mac. Are you sure you know anything about Macs?
\_ How do you force it to hibernate so you can swap?
\_ Close lid, wait a few seconds. Or press the
power button and select Sleep. Or select Sleep
from the Apple menu.
\_ Sleep != Hibernate. If you put your Apple
laptop to sleep and remove the battery,
you lose your session. You can make
them hibernate with energy saver setting
tweaks, but the hibernate mode is
very slow compared to PC laptops. -tom
\_ Actually, it is, and you don't. (I just
tried it to be sure.) If you put the
machine to sleep, pull out the battery,
then put the battery back in, it takes
a while longer to resume, but you don't
lose your session. The same happens if
your battery runs down while the laptop
is on standby.
\_ Non detacheable battery?
\_ The new macbook pros are internal battery only,
but that is irrelevant, because...
there is still no extended battery option.
Why carry multiple batteries and have to power
down/switch batteries instead of having a single
heavier battery that lasts the entire flight?
I don't see the advantage.
\_ I get almost 7 or 8 hours of compute time on
my new macbook pro. I guess I could whine and
wish it lasted longer and that I could fit in
another battery, but I will chill. 7 hours
is a long time.
\_ fair enough. What PC do you prefer? Toshiba?
IBM?
\_ I've had toshibas and IBMs (pre lenovo),
I've not liked HPs or Sonys. I've even
had an eeepc that I used as a spare.
\_ MacBook Air.
\_ This is as ghey as driving an Audio TT.
\_ My wife loves her MacBook Air.
\_ Before the tosh i've had:

| config.fsf.org/rms/wiki?name=rms Important Notes When receiving hardware for RMS that is hard to replace, please, before you do anything else: 1 Do a full backup of the as-shipped state of the software on the device, in a way that makes it easy to do a bare-metal restore if needed. lemote yeeloong Previous Laptops From most to least recent: * Rms laptop - lemote lemote yeeloong with debian - Deprecated * Rms laptop - lemote menglan with debian - Deprecated" Rms laptop - lemote menglan with debian - Deprecated * Rms laptop - olpc xo with custom fedora - Deprecated" Rms laptop - olpc xo with custom fedora - Deprecated * Rms laptop - thinkpad with gnewsense - Deprecated" Rms laptop - thinkpad with gnewsense - Deprecated * Rms laptop - thinkpad with ututo - Deprecated" Rms laptop - thinkpad with ututo - Deprecated General Guidelines Backups When getting a new laptop, we want to create a backup, both to be able to get back to a known-good state, and to check up on the as-shipped freedom of the laptop later. RMS Acceptance In general, it is not a wise idea to give a laptop to rms until the following conditions are met: * Suspend is working completely (hibernation support is not needed) * We have the proper cables/tips for his numerous power devices (see below) - should order these as soon as possible after getting new equipment. Also generally look around for any big useless files / applications that can be removed if hard drive space is at a premium on the system. d and /etc/X11/Xsession to disappear, leading to hard-to-diagnose issues with X (login, but gnome-session failing to start, although it would work fine in failsafe mode). Printing Printing should work from the FSF offices, and (more important) from MIT Stata Center. Universal Peripherals These are peripherals that should be usable with most laptops, although additional cables/adapters may need to be ordered, and they all need to be tested with any new hardware. RMS Support boxes There are boxes in the Sys Admin office marked "RMS Support" - they contain duplicates of most of the equipment in this section, plus some other devices for testing and quick replacement purposes - if you buy a new peripheral for RMS and it is not disgustingly expensive, please buy two and put one in one of these boxes. They provide no useful technical specs for cables/tips on their web site. See rt:367502 for 2 alternative manufacturers of similar devices that seem to be more open with their specifications. Also, their web store sucks, is uncommunicative, and does not ship things in a timely manner. newegg - do not order from valence's yahoo store, it is a black hole - they do not respond to emails or phone messages, and you are lucky if things ordered with overnight shipping get shipped at all. Depricated Big Battery - Bix BP170 170 WH capacity battery, aluminum natural finish case, same footprint as laptop. com / BiX Computers 9651 Irvine Center Drive Irvine, CA 92618, USA Tel. Has its own AC charger (which means another thing to carry around). RMS was going to look into using the other iGo adapters he has to avoid this. We have had major quality issues with these batteries and should not purchase another. Current Big Battery - APC UPB90 RMS is currently using an APC 90-Watt-Hour Universal Notebook Battery (UPB90). It comes with a bunch of tip sets, including tip set "b", which is what works with both the full-sized and mini lemote laptops. that is auto-sensed in a range of 15V-20V, although experience has shown it works better to manually set the output voltage via the front panel display on the battery. Besides the output for the laptop, it has 2 USB power outputs, which can be used to charge cell phones, or provide extra power to devices that need it via USB "Y" cables. It is Model UPB90, Serial Number 6A0734B96580 and the # for service is 800-800-4APC. See rt:397833 The hours left readout of the battery tends to lie in a way not favoring the battery. The Multi-charger - iGo Everywhere 85 The iGo Everywhere 85 replaces the previous iGo Everywhere 65 RMS had. linux-uvc based USB webcam for this purpose - uvc is the "future", and is a standard, as opposed to the fifty billion different chipsets that exist for a lot of older webcams. The linux-uvc drivers should work with Ekiga and friends, and they compile, install and load fine on gNS, and work. Update: The webcam works perfectly in Edgy, since the driver compiles correctly under Dapper I expect it will work fine with gNewSense/Ekiga. It's a very high quality camera and works astoundingly well in low light. ENCORE ENUWI-G2 USB Wifi adapters, which use the exact same chipset (as reported by "lshw" - "RTL8187B_WLAN_Adapter") as the Lemote Mini-Laptop (but seems to have a better antenna). USB Powered Hub Sometimes a laptop will not supply enough power for the USB devices. LG Black/Silver 8X DVD+R 8X DVD+RW 6X DVD+R DL 8X DVD-R 6X DVD-RW 5X DVD-RAM 8X DVD-ROM 24X CD-R 16X CD-RW 24X CD-ROM 2MB Cache USB 20 Slim External SUPER MULTI DVD Burner with LightScribe Model GSA-E50L - Retail. USB Sound Card What do you get for the man who seems to have everything? StarTech ICUSBAUDIO 2 Channels USB Interface Audio Adapter - Retail! It probably won't work with the Lemote 2e laptop either, but at least he can't say you didn't try... Swiss+Tech Utili-Key XT 8-In-1 so he can get at the insides of his laptops on the road if he needs to. This model was chosen because it doesn't have a blade and looks like a key, so will probably get by the TSA. Screwz-All 4-In-1 tools, but these have blunted tips which make them useless for small laptop screws. It is also supposedly faster for things RMS cares about, like initial boot time. It's a OCZ Technology 25" 64GB SSD SATA II OCZSSD2-1S64G (rebranded Samsung MCCOE64G5MPP-OVA). as of Q1 2009 these things look important to get: * Get SLC technology, not MLC * Be sure to research power requirements. Although some SSDs use considerably less power than conventional hard drives, plenty of them use more (due to the use of FPGAs and other low-volume cost-cutting measures). Using SSD Filesystem JFS with nointegrity doesn't seem faster than ext2 overall, and ext2 is more tested / probably has better fsck, so just use it for everything. Mount with "noatime,nodiratime,nouser_xattr" to minimize writes. dclark@tux:$ grep ext2 /etc/fstab UUID=3798bdac-3d77-4bcd-975f-38eaf083953d / ext2 noatime,nodiratime,nouser_xattr,errors=remount-ro 0 1 So use the ext2 filesystem with this drive to avoid extra writes that happen due to journaling since flash memory will eventually wear out. Ext3 also does things that don't matter with SSD, like trying to avoid file fragmentation. as SSD becomes more mainstream, ext4 or some new filesystem will probably grow a I'm-running-on-SSD mode. Elevator Use "elevator=noop" as the other elevators are all workarounds for the physics of spinning magnetic media. lst # kopt=root=UUID=3798bdac-3d77-4bcd-975f-38eaf083953d ro elevator=noop (then run update-grub) Temporary Files and Swap Use tmpfs for /tmp (and also no swap space or partition) to avoid lots of temporary writes to disk. Any programs that do a lot of temporary caching (eg firefox/icecat) should be modified to put their caches under /tmp (instead of user home directories). t=47512 SD Card Transcend SD cards use SLC, so should last longer than other cards. We will experiment with putting the ext3 log on SD, as if they do burn out from read/write cycles they are much cheaper to replace. We will also experiment with ext4, as ext4 checksums the journal, which may be more important with SD than other types of media. |
