Your own su­per­com­puter and back­ing it up, pin­ing for fea­tures of the past, wor­ry­ing about pass­words, and mu­sic tag­ging.

Ku­dos on the good su­per­com­put­ing news for Linux. But, you did not men­tion how many of the server im­ple­men­ta­tions are sub­scrip­tion or pur­chased based? I men­tion this be­cause many things come and go quickly in the Linux en­vi­ron­ment. For ex­am­ple, Unity desktop is no longer sup­ported on an Ubuntu re­lease higher than 17.04, and Sys­tem­back isn’t sup­ported af­ter Ubuntu 16.04 LTS. I have used a Linux plat­form in my work for over 10 years (net­work vul­ner­a­bil­ity as­sess­ments and foren­sics). How­ever, I haven’t con­verted my home com­puter to Linux.

I re­cently re­tired and was eval­u­at­ing which OS to use for all my per­sonal needs. I re­quire se­cu­rity, sta­bil­ity, longevity, and sup­port. The OS must work seam­lessly on a mo­bile de­vice such as a lap­top. A touch­screen is not im­por­tant. I have an is­sue with Linux OS plat­forms and user data re­cov­er­abil­ity and restora­tion (from one lap­top to another sim­i­lar but not iden­ti­cal lap­top) in Linux. Ubuntu 16.04 LTS was fair. How­ever, Sys­tem­back is no longer sup­ported and Pin­guy re­ally was a step back. Rsync never re­ally did work for me. I’m will­ing to pay a sub­scrip­tion fee or pur­chase amount for that which meets the afore­men­tioned re­quire­ments.

I may sound like a heretic now, but if you want the same suc­cess in the home mar­ket as in the server mar­ket you may wish to go the route of (dare I say it) Ap­ple and Mi­crosoft. As for me, I will con­tinue to play with Linux, but that’s all I’ll do with it un­til some­thing changes. TimBever,vi­ae­mail

Let’s not for­get DéjàDap, now known more sim­ply as

Backup. It might be a lit­tle ba­sic for your tastes but it’ll do the job of keep­ing your /home backed up and isn’t that what we’re re­ally about? If rsync seemed to be more your thing there’s a frame­work called Backin

Time that utilises rsync, which could be worth a look. We should do a backup fea­ture…

Those su­per­com­puter com­plexes cost multi-mil­lions to build and typ­i­cally tend to be run­ning their own builds of Linux. The cur­rent fastest Sun­way Tai­huLight (93 petaflops) is a Chi­nese project to demon­strate Chi­nese en­gi­neer­ing ex­cel­lence util­is­ing its own SW26010 260core many­core RISC pro­ces­sor and Sun­way RaiseOS Linux. Another ex­am­ple is the sixth ranked IBM Se­quoia (17.1 petaflops) run­ning a Power Ar­chi­tec­ture pro­ces­sor and uses RHEL, so likely will have some sort of ser­vice agree­ment with Red Hat. All of this is way above my pay­grade, but I’m hop­ing to have a fea­ture on Linux use in high-per­for­mance com­put­ing cen­tres soon.

There’s a su­per­com­put­ing arms race and China is def­i­nitely win­ning.
