The Karpen Pile, currently on display at the Dimitrie Leonida National Technical Museum in Bucharest, Romania, still gives out 1V after 60 years.

This one has a glass enclosure so it can be studied.

psergiu Amazon Book Price (92 comments)

I see the book price in the provided Amazon link as US$ 48.10 for the Paperback version.
Everyone sees the same price ?

Slashdot has given us a Amazon link - let's investigate if we get a lower or higher price when accesing the link from Slashdot as compared to other ways.

Longtime Debian Developer Tollef Fog Heen Resigns From Systemd Maintainer Team

psergiu Re:How systemd became Debian's default init system (550 comments)

How about using /etc/inittab to monitor & restart your daemons like all good Unix admins are doing since last century ?
Oh ... you only know about RedHat's netutered inittab ? Too bad. Let's all switch to systemd because AC is too lazy to read a man page.

(Bitter because i just had to reinstall a Jessie machine from scratch after a filesystem corruption borked 2 system-d config files - the system would not come up even in rescue mode as systemd was spewing 2 pages of errors on the console then hanging)

Eben Upton Explains the Raspberry Pi Model A+'s Redesign

psergiu Re:Nice and all (107 comments)

There are _NO_ 1Gb DDR1 chips in that form factor.
If you can manage to persuade any memory factory to build a couple of million of them at a price simmilar to the existing 512Mb ones - the whole world will be thanful.
All the 1Gb chips on the market now are DDR2 or faster - incompatible with RPi.
Eben Upton & the Foundation has tried and failed - nobody wants to make so few 1Gb DDR1 chips for so cheap.

Too bad OS X is opensource.
We should all switch to a truly proprietary OS. Anyone has any advice on which truly-proprietary OS is better security-wise ?

Slashdot Talks WIth IBM Power Systems GM Doug Balog (Video)

psergiu Workstations ? (36 comments)

As the video won't play (even alt link), i want to ask:

Any plans for [somewhat] affordable Power8 workstations that can run AIX and some limited PowerVM (something like IntelliStation POWER 285 where you can have 2 LPARs)

IBM Gearing Up Mega Power 8 Servers For October Launch

psergiu Re:Workstations ? (113 comments)

Yes, almost surely IBM won't alow AIX to run on those boards.
Linux can run on any old x86 cheapie - there's nothing useful to do with a Power 8 CPU running Linux:

- Are you able to learn something that can be applied to big-iron Enterprise IBM hardare ? No.
- Are you able to run any 3rd party commercial software on that Power8 Linux box ? No - most 3rd party Linux commercial software only provides x86 binaries. Sometimes ARM.
- Are you able to do the exactly same Linuxy things with a cheaper x86 machine ? Yes.

Yes, it's a new and exciting CPU, some hobyists will buy this - but for most of them, after a couple of months, the Tyan power 8 machine will remain unused or will be downgraded to a "seldom used server in the corner" as it's less usefull than a Raspberry Pi.

IBM Gearing Up Mega Power 8 Servers For October Launch

psergiu Workstations ? (113 comments)

Latest Power workstation had Power 5 CPUs. The should make a new workstation.

No workstations => No small computer labs => Weak interest for the OS/Hardware from sudents & hobyists => Future decline of sales in servers.

Look at HP & all the other commercial Unix vendors - decline in server sales is almost directly related with workstation unavailability in the past ~5 years.

Systems That Can Secretly Track Where Cellphone Users Go Around the Globe

psergiu Re:Storm in a teacup (76 comments)

Well ...
As long as you can push a SIM-App to that Phone's SIM card, that program can periodically send updates with the current location (Network ID, Cell ID, power) to another network-connected device without the owner ever knowing. It's invisible even to the phone OS, as everything happens inside the SIM and radio module)

And all newer SIM cards (all that have a SIM Application menu, 2001 or newer) can do this, and your network operator (or anyone having the proper network access) can push something OTA to your SIM. You will just see your phone losing it's mobile network for a couple of seconds and reconnecting - that was the SIM's CPU rebooting with the updated firmware.

Choose Your Side On the Linux Divide

psergiu Re:My opinion on the matter. (826 comments)

Systemd's strenghts are:
- Fast startup & shutdown (compared to sysVinit);
- Better on-demand loading and stopping services and processes and changing network settings.

Compared with all the problem it brings:

- That is useful on a tablet or phone - where you never have to modify the factory configuration;
- A bit useful on a laptop - if you only use GUI tools that can do a limited ammount of config editing for you;
- Not very usefullon a desktop - unless you are prepared to get your hands dirty with systemD's smelly and poorly-documented guts;
- Useless on a server - where you only reboot 4 times a year or so and never have to hot-plug anything or change wireless networks.

For a server situation, the BSDrc style startup is even better than sysVinit.

Choose Your Side On the Linux Divide

psergiu Re:Display server (826 comments)

As long as xterm & the web browser are running on Wayland, nobody will complain.
X.org has became such a mess itself (compared to the old XFree86) so anything smaller, simpler, faster and 100% compatible is welcome.

OTOH systemD is not smaller, simpler and 100% compatible with the systemV init and BSD rc - so it requires everybody relearning a lot of concepts for scratch just to gain 4-5 seconds at boot time - unsually on a server that you reboot only a couple of times a year.

CherryPal's $99 netbook scam

psergiu psergiu writes  |  about 5 years ago

psergiu (67614) writes "Hailed everywhere as revolutionary, Africa, the $99 netbook from CherryPal has failed to deliver. At all. Thousands of orders were made and nobody has received yet a unit or even their money back. Max Seybold, the CEO of CherryPal has even started to send threatening e-mails to the owners of blogs with unfavorable comments posted by the users. The only Africa netbook that was supposed to be delivered turned out to be a hoax too.
So, no $99 netbook for us yet."
