32 bit usage – survey results

Running 32 bit Ubuntu when the hardware technically can do 64 bit
32 bit running on 64 bit capable hardware

  • hardware issues varied from EUFI 32 bit only, to printer and driver issues
  • application included wine (try building wine on 64 bit…)  and virtualization
    • some 64 bit users use 32 bit images for virtualization to use less RAM
    • Not in survey but I know of others who use 32 bit specifically to work with Android.

Arch vs Desktop Environment vs Release

Desktop environments vs arch vs release

Please do not use this to really compare desktop environments!  If multiple answers I took the least resource intensive one! (Next time I do this.. I should just require users to pick a primary one)

 Impacts over Releases

Impact

  • Switch from Ubuntu – also includes plans to stay on old unsupported version until hardware dies
  • Moderate is somewhat a catch all
  • If I do this again, I should just have a 1-5 sliding scale, in addition to a text field.
  • Users are concerned about having to throw out old machines, not having an upgrade path to go from 32-> 64 bits, and the cost to upgrade.
  • Select Comments (many more in the raw data of course!)
    • As an aspiring software developer, phasing out 32 bit support would be great for me as it means one less build to maintain.
    • I plan on reinstalling Ubuntu on this laptop as a 64bit install at some point anyway.
    • Unless the schedule changes, no impact. We’re planning to do the switch late 2015 / early 2016.
    • I will have to stay on 16.04 forever on that machine. The needed drivers are not going to be available in an open-source form.
    • My parents + my children have no PC
    • we have old PC’s in the hospital and i don’t think this hardware would be upgraded.
    • If the majority of freely given computers we receive are still 32-bit by then, we’d have to respin another distro. But, like PowerPC; all good things must come to an end.
    • Just need to figure out how to make the switch. If it means re-installing, bah.
    • It is terrible, because my eeePC only has 1GB in it.
    • One more reason to decommission the hardware.

I think the original plan can still work, but like any good survey we know have more questions to ask!

  • Lubuntu/Xubuntu support for 14.04 LTS is 3 years not 5.   It’s going to be a LOT higher impact if they don’t have support in 2019/2020 (which would be the case if 16.04 is 3 years too).   This could obviously be mitigated by moving 32 bit to ports and having it be opt in.  Lubuntu/Xubuntu 18.04 with 3 years would get us to 2021.
  • What can we do to make virt use less RAM?  (Lots of Virtualbox)
  • What can we do to make bare metal use less RAM?
  • Building Wine on 64 bit? (The two easiest methods are defunct if we remove 32 bit images I think… http://wiki.winehq.org/WineOn64bit)
  • Can we do an actual upgrade path?  Or at least start officially testing 32->64 “upgrade” re-installs?

Just to complete the application compatibility story (not from survey), Games are starting to be 64-bit only:

Still running 32 bit Ubuntu?

I’m considering a proposal to have 16.04 LTS be the last release of Ubuntu with 32 bit images to run on 32 bit only machines (on x86 aka Intel/AMD only – this has no bearing on ARM). You would still be able to run 32 bit applications on 64 bit Ubuntu.

Please answer my survey on how this would affect you or your organization.

Please only answer if you are running 32-bit (x86) Ubuntu! Thanks!

Ubuntu 14.04 LiveCD Memory Usage Compared

memoryusagegraph

I did a comparison when 14.04 was first released on the memory usage of different Ubuntu flavors.   Some takeaways:

  • Lubuntu has zRam (automatically compress memory to save space) enabled by default making it hands down the most usable version with low-memory.  It’s the only flavor to have it enabled on the LiveCD.
  • The real cost of 64 vs 32 bit is usually only 128 MB.
  • Lubuntu (32-bit) still boots with just 160 MB of RAM!
  • The Ubuntu kernel can’t boot with only 128 MB of RAM.

All testing was done in virtual machines (Virtualbox) and obviously with different hardware you’re results will vary.   You can infer some of my methodology from the notes below.   This was done months ago and I don’t remember all of the details.  The results may have changed with software updates, especially to Firefox.

Lead (Pb) in the USA

Live in the US?  Did you know that we put Lead (Pb), a known neurotoxin, in:

  • Garden hoses (that have been shown to leak Lead into the water)
  • Power cords (including laptop cords)
  • Carseats (mostly to the base, some other toxins have been found in the seat itself)
  • Likely more, it’s apparently not uncommon to be added to plastic…

In the EU you aren’t allowed to put Lead in the above.  I think it’s time we joined them!

  • Sign the petition on the White House We the People site.
  • Donate to this Indiegogo campaign to test carseats for toxic chemicals. (They are only asking for $10,000! ~ mostly to buy the carseats)
  • Share this post / the above with friends, family, and any celebrities you happen to know on Twitter, etc.  #NoSafeAmountOfLead.
  • Bonus: Watch episode 7 of the new Cosmos which ends with Neil deGrasse Tyson saying there is no safe amount of lead.

Please let me know if you have trouble doing any of the above..
