Ask Slashdot: Unattended Maintenance Windows?

psergiu Simmilar experiences ... (265 comments)

A friend of mine lost his job over a simmilar "automation" task on windows.

Upgrade script was tested on lab environement who was supposed to be exactly like production (but it turns out it wasn't - someone tested something before without telling anyone and did not reverted). Upgrade script was scheduled to be run on production during the night.

Result - \windows\system32 dir deleted from all the "upgraded" machines. Hundreds of them.

On the Linux side i personally had RedHat doing some "small" changes on the storage side and PowerPath getting disabled at next boot after patching. Unfortunate event, since all Volume Groups were using /dev/emcpower devices. Or RedHat doing some "small" changes in the clustering software from one month to the other. No budget for test clusters. Production clusters refusing to mount shared filesystems after patching. Thankfuly on both cases the admins were up & online at 1AM when the patching started and we were able to fix everything in time.

Then you can have glitchy hardware/software deciding not to come back up after reboot. RHEL GFS clusters are known to randomly hang/crash at reboot. HP Blades have sometimes to be physically removed & reinserted to boot.

Get the business side to tell you how much is going to cost the company for the downtime until:
- Monitoring software detects that something is wrong;
- Alert reaches sleeping admin;
- Admin wakes up and is able to reach the servers.
Then see if you can risk it.

Comcast Converting 50,000 Houston Home Routers Into Public WiFi Hotspots

How long before someone releases a tool that would have a Linux-running computer or device with a WiFi card masquerading as an official Comcast WiFi hotspot an collecting the usernames & passwords of the users trying to connect ?

Tiniest Linux COM Yet?

They did, in April:

OpenSSL To Undergo Security Audit, Gets Cash For 2 Developers

psergiu Re:"Audit"? Try massive rewrite. (132 comments)

> ... One big mistake is not a reason to scorch and salt the earth.

Listen, lad. I've built this kingdom up from nothing. When I started here, all there was was swamp. All the kings said I was daft to build a castle in a swamp, but I built it all the same, just to show 'em. It sank into the swamp. So, I built a second one. That sank into the swamp. So I built a third one. That burned down, fell over, then sank into the swamp. But the fourth one stayed up.
An' that's what your gonna get, lad -- the strongest castle in these islands.

A 32-bit Development System For $2

psergiu Micromite (138 comments)

Here's a better one-chip sollution:


PIC32 running a full BASIC interperter (ANSI X3.113-1987, with optional line numbers, structured programming features like do loops, multiline if statements, user defined subroutines and functions. )

You don't even need to install Arduino or another IDE to use-it - you just need a VT100 terminal emulator and use the built-in editor.

You Can Now Run Beta Versions of OS X—For Free

psergiu Re:New OS X is free* (201 comments)

But you already got the old OS X for free when you bought your mac. So the new one is double-free :)

Oh, you want to install-it onto a uncool PC ? You dirty, double crossing, good for nothing, two timing software pirate hacker ...

Born To RUN: Dartmouth Throwing BASIC a 50th B-Day Party

psergiu Re:BASIC bad, ?? good (146 comments)

I recommend MMBasic on a Maximite

Quoting from :

MMBasic is a free and open BASIC interpreter for 32 bit microcontrollers.

It includes floating point numbers, extensive string handling, multi dimensional arrays and structured programming features like do loops, multiline if statements, user defined subroutines and functions.

MMBasic is generally backwards compatible with Microsoft's MBASIC and implements much of the ANSI Standard for Full BASIC (X3.113-1987).

Get your kids a Maximite.

80Mhz, 128Kb RAM, 8 colour, Stereo Amiga-MOD playing, very hackable BASIC computer.

Just add a VGA monitor, PS/2 keyboard and SD card for storage.

Raspberry Pi Compute Module Release

psergiu Re:How about a backplane? (51 comments)

It depends.

How about a 1U rack-mounted box, with redundant PSUs, hosting around a hundred of Pi SODIMMs, with a USB-Ethernet chip for each slot, every X (7..24) ethernet lines connected to a switch chip with a gigabit uplink on the back of the enclosure.

Current RPi USB-Ethernet is slow because of the USB-HUB-and-Ethernet chip used. You won't have a USB hub in this configuration, and you can use a better USB-ETH chip.

Also you don't need a single, huge, expensive PCB. You can have multiple small PCBs side by side each one hosting just X (see above) cards.

Put a small switch next to each RPi DIMM slot on the board so you can power them off and replace-them online.

Need more local storage for each node ? - you can have a SD-Card slot next to each Pi slot - there are 46 GPIO available pins for those kind of extras (RTC, temperature, front panel leds & reset button for each RPi DIMM)

And Liz just let slip in the announcement comments that Broadcom might enable some extra functionality (ETH, SATA or other fast interconnect) on those extra pins.

Raspberry Pi Compute Module Release

psergiu Re:BUT, More RAM please sir... (51 comments)

The BMC chip can access 1GB of RAM, but unfortunatelly 512MB is the largest size currently produced in that form-factor (Chip-on-Chip BGA DDR1).
And the Raspberry Pi Foundations does not buy RAM chips in enough volume to justify to any vendor a custom made memory chip at that price.
So we're stuck with 512MB ... unless this new SODIMM form-factor is so succesful that they have enough volume to get that custom 1GB chip made for them at the same price as the current 512MB one.

Linus Torvalds Suspends Key Linux Developer

psergiu Re:systemd Architecture (641 comments)

As a sysadmin using RedHat in production environments, i will not recommend upgrading to RHEL7 if it uses systemd as it is now, with no backwards compatibility:

1) We have tons of old proprietary software which only knows about init.d startup scripts, cron & so on. That software will surely not get updated to be systemd-aware by the vendor and we cannot make "hacky" things for compatibility as we lose any vendor support.

2) journald does not support remote logging. When you have servers handling PCI data, you spend more on external hardware & software who make sure all PCI data is protected than you spend on the server itself. No remote logging = no go for systemd.

Also, on a production server, you really don't care if the OS startup scripts run in 1 minute or 15 seconds. You still have to wait 5+ minutes for the BIOS to finish the memory & hardware tests, the [proprietary] DB still takes a lot of time to start up.

CherryPal's $99 netbook scam

psergiu psergiu writes  |  more than 4 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."
