If you're not happy/satisfied at the current job, you have a reason to change. If you dread going in on a regular basis, you need to change something.

I recently left a place where the work was ok, I liked my coworkers, but I dreaded going in. I'd procrastinate because management would change my tasks behind the scenes or create situations that created more work to little benefit. I had little say in decisions and was discouraged from trying. My new job puts me on truly cutting edge, I get great feedback from management with lots of input and I'm working much harder.

I also find I'm eating better and feel healthier. And as a result of my 2 month job search, I know how much my skills are in demand. If this job doesn't last, I'm not worried about getting another. My skills will be much higher. They were stagnating in mundane tech before.

Exactly this. When the firmware automatically substitutes good sectors to replace bad sectors, you can't erase the bad. If there was sensitive data on that bad sector, you can no longer get to it to erase it unless you use a vendor (and model) specific program. Even if you have software for every drive, it will take far more time and labor to erase all the data. A shedder does it in minutes. You can't even spin a drive up that fast.

If your data is less sensitive that a sector being exposed is ok, use those general purpose wipers like dban. I think my home drives are ok (I know what data was on them and encrypted sensitive data). Work drives, not so much and shedding is less labor anyways.

Remote wifi temperature sensor. I have an existing 1-wire temp sensor net & wanted to put something in the greenhouse w/o running a wire. I just needed to add a cheap wifi dongle and it just worked. I took a small $ risk and almost no time. If I was doing 10-20, there are cheaper solutions for more time spent, but I think I got a good value.

Since then, I played with RiscOS on it. I'm now playing with it as a thin client that someone built. I'm also going to play with Plex on it. Maybe I'll play with Plan 9 on it.

The first task could probably be done on on any of the other ARM boards that run Linux. The others tasks might work on other boards, but people are building and optimizing for the RPi.

All these ARM and microcontroller boards are fantastic. RPi made the others hit the under $40 price point. It reminds me of the days of Apple vs C64 vs Atari vs IBM and I hope they stick around.

Conserver is great. I've used it to monitor Linux consoles after boot (via grub handoff to serial console). Serial consoles are cheaper per port then KVM port and you have a log you can grep.

I've also used it to monitor several consoles going to embedded devices. The users could take over when a coworker had gone on vacation w/o calling the sysadmin.

MH stores each email as a plain text file, each folder as a directory. It uses the unix filesystem as its database. It's very quick and has tools to re-order a folder quickly.

In addition, MH has tools to convert mail formats. It was designed in the days of low cpu power and small disks. It also lent itself well to being wrapped by other tools like xmh, exmh and mh-e so you don't have to learn the raw MH commands.

Yes, IMAP is cool, but don't discount MH. Plus the O'Reilly MH book is free as a PDF.

Oh, some IMAP servers and mail clients use MH format or something derived from it.

DEC had a number of MIPS based computers that ran Ultrix.

DECstation 3100, 5100 workstations.
The 5900 (and 5800?) mini computer.

Ultrix ran on Vaxen and MIPS systems.
The Alpha chip and OSF/Digital Unix/Tru64 replaced MIPS and were much faster.

I think SGI had Indy and Indigo2 systems at the time of the DECstations. They may have preceeded the purchase of MIPS by SGI

Reboots to fix problems should never be done.

Reboots as a matter of policy isn't a bad idea.

If your system reboots periodically, you force network disconnections, memory cleanup, etc.

Users that logged on months ago are no longer tying up resources. Maybe they don't need it but forgot to logout. Or their client died so there's a zombie on the server.

Administer? No. Debug? Yep! http://www.linuxplanet.com/linuxplanet/tutorials/7295/1/

I don't run vim if it's not part of the OS. I run /usr/bin/vi because it's part of the OS. On Linux it might be vim. On BSD it might be nvi, on Solaris it's vi.

Real Unix vets know how to use the tools that came with the OS and don't *have* to use extra stuff. But we'll use nmap if we have it. Or emacs.

FWIW, you can use echo * when ls isn't available.
