    After all that calm, good advice, was this where your blood suddenly started to boil over?

    I could almost hear your teeth gritting... "those bastards!" :-)


    Actually, most of what I related came from friends who worked in IT before all getting laid off. I decided that those would be a lot more relevant than my own anecdotes, which mostly have to do with juggling
    • a regional legacy service decommission, given a couple months to do by myself what senior people had been trying to do for the last 3 years, including:
      • arranging with unmotivated sales staff (no residuals, no commission, small accounts that didn't even count towards quotas) to upsell any of the customers who hadn't left yet;
      • yanking back IP space from people that would be quitting or that would be staying but would have to get reassigned anyway;
      • determining who owned each legacy circuit without many CID records, so that we could either disconnect and stop paying telco, or tell the customer they should do so

    • work as part of a team, that required that we yank back many, many IPs from many, many customers who'd had them for many, many years, most of whom we had to discover as we went along because there was no surviving documentation, and many of whom couldn't justify but still expected the same amount of space despite ARIN usage requirements, facing very short deadlines for each block that needed returning. I can't tell you further details.
    • an international circuit database scrub. I can't tell you details of what this meant, either.
    • other projects as they popped up daily/weekly, which I've probably just blotted out entrely


    In addition to all those, I also had my regular duties, which included supporting the customer routing infrastructure, then still taking weekly turns on 24-hour pager duty after I was too busy to do the daily support. Oh, and maybe a few escorted colo visits. And calls from the company president's office to fix other departments' problems. And that emergency customer premises visit...

    I figured if I said anything about those, I'd get cranky, or you'd get bored, or think I'm desperate to show off so someone will hire me (I made it through 3 rounds of layoffs cleaning up the messes, but there were at least 4 rounds, so you'd be right about that), or I'd say too much and get sued by my former employer (I've just gone back and removed most of my text. But my former bosses can still reconize me immediately), and none of these really sound like system administration issues, which is what the root article is about, so I won't.

    Too bad, too, because I could have mentioned how I got the decommission done with a month to spare. And how I did the last year of projects and support 90% from home, especially after the secretaries, then some fellow engineers, then my boss got laid off, and the office lost its soda budget! Oh, and that all the work at home was done over dialup, frequently at rates like 21.6K. :) (Thank God for SSH and screen)

    But who wants to hear about those things? :) (anyone needs a good team player with Cisco/Juniper/angry customer experience, let me know :) )

    I'm not talking about consumer-grade devices that aren't reconfigured often, I'm talking about "production" equipment used as regional aggregates, that have T-1 and DS-3 and other cards hanging off them, that get updates every day as new circuits get put in, existing circuits get changes in IP routing, interfaces get shut down because customers don't pay the bills or get caught spamming, etc.
    Devices that might see the equivalent of hourly saves throughout their use, frequently for very minor changes, in bursts.

    ("oops, I forgot to increment the date in the header, the config server won't rebuild the new routing tables, better do it again," "did i save it after shutting that interface a minute ago? better do it again," "That guy wants to add BGP, here's his ASN," "oh wait, he was wrong, that's his downstream's ASN, he's this," "oh, he doesn't want to pay for BGP, he wants static routes," "ok, his salesguy talked him into it," "oh, no, he's multi-homed and didn't tell us, and his other providers' space is not portable, so we need to drop his announcement of their space until he sends us permission from them," "oh, his downstream is spamming, jerks!" "oh, no, actually he lied about it being a downstream, he really owns that company too, do a shut until he calls us so we can chew him out," "his other provider's NOC just alerted us that they yanked his space, so remove the BGP totally until he fixes the route objects," "oh, accounting called, his check bounced also, yank his keycard access to the colo at the POP and padlock his rack, then remove his configs for his home T-1 also," "dude, some guy showed up at the data center, pulled a gun, and got arrested, was it him? no! it was the consultant who built a box for him, who got ripped off too! Guess you'll have to wait for legal's approval before disassembling his boxes with prejudice, but they'll probably tell the guy they won't press charges if he goes away quietly, since he just got hauled off by the cops"), etc.

    That's the kind of use production routers get, all day (and night). Except in reality, the deadbeat's box at the POP may become our new secret quake server eventually instead of being dropped off the loading dock or sold at auction, so it will be routed some IPs from the office pool, which involves more routing changes... :)

    Give estimates. Show your time table. Put the onus on someone else to fit it in, so they are clear on what the tradeoffs are going to be.


    Seriously, this is basically all there is to it. Use whatever calendaring software you have to break down what you're doing on a daily or weekly basis, if not hourly. Even a recurring to-do list is good. The idea is to show that your time is not an infinite resource.

    If you can sit down and say something like "I can make time for this project this month, but it will require moving back those security updates for a week, and the database migration for a few days. Also, we're running low on shared drive space and there's no budget to augment the servers, so to add this in, I'll have to put everyone on a harsher quota for the next few days (and delete your mp3s off your shared drive)," and show how your time is mapped, they will see why they can't reasonably expect you to take on more work.

    You'll also be able to get more actual work done, because the mere act of organizing your regular activities will let you see ways to cluster them for more efficiency ("oh, while this disk image is copying, I can hit that next item on the list, replace the video cable on that secretary's computer so she'll stop holding my mail hostage"), etc.

    Also, at the end of six months or a year, maybe you can use the resulting log as evidence that you need an assistant or a pay raise or both. It's also good for remembering what to put on your resume, if your small company decides to lay you off and replace you with two kids who just graduated and also happen to be related to the VPs...

    And I do think CF is more reliable than Microdrive.


    Now there's an understatement. Solid-state versus a tiny little hard drive. Drop both into your pocket without any protective cases, let them bang up against each other, your keys, loose change, and the side of your desk as you swing into your chair, for a few weeks. Step on them accidentally (on purpose) when you change clothes at the gym, or when you're at home with your honey (Slashdot regulars excluded) and in a hurry to undress...

    Microdrives are cute, and store a lot of data, but they still rely on hard drive technology, so they still have floating heads less than a hair away from fast-spinning disk surfaces. Probably any failure point CF has, microdrives also share, as well as their own. Even if they are as externally as rugged as CF (and I think the tests above may disprove that), you can't get around the internal points of failure.

    Flash RAM has quite a limited number of writes. This can cause problems if you're writing large numbers of small files to flash RAM as it can cause a huge number of writes to the FAT area of the device.


    That's odd. Flash sees heavy use in routers. When I was an engineer for a Tier 1 provider, being conservative and cautious always meant saving more often, not less :)

  7. Re:I've had no luck with Flash Media on Might Flash Memory be a Viable Backup Medium? · · Score: 1

    I've had extremely good luck with my CF cards. I first started using them personally when I bought a Canon digital camera, and as long as the reader device worked properly with my computer (various OSes and readers tested), the data was always there. I read them as FAT drives (I never used above 48M cards, because my Powershot A5 supposedly can't use anything higher, so higher sizes might use FAT32). In fact, I think I remember using Ontrack's data recovery software to recover some files I accidentally deleted off a card, but I'm not sure. More importantly, though, I've gotten one wet, dried it out, and it still worked (don't rely on this, though). In fact, the only time I couldn't read a card was when there was lint or dust clogging a couple of edge connector holes, or I didn't have a card fully seated in the camera.

    I've known people who've cracked the plastic shells, and some of the cards didn't work any more - but some of them did, at least long enough to move the data off. And any kind of mechanical damage harsh enough to crack a CF card open is more than enough to destroy most other storage media too, probably.

    Don't forget, some routers use flash memory to store configuration data. in fact, that application probably helped drive the early development. They're not the fastest media, but they're a very rugged solution.

    If you're losing data all the time on your cards, check that you're not using buffered writes and removing them before they're ready, or that you're not nicknamed Sparky because of a chronic static charge :) Seriously. Or try a different brand. For CF, I've used Lexans that were on sale, as well as plenty of Sandisks, and the tiny "free" Canon-branded card that came with my camera. For SD, I've only used the Canon-branded card that came with my videocamera), but it wasn't great at making stills, so I didn't get much practice. I have no experience with SmartMedia. Oh, and my parents had a lot of trouble getting data off their Memory Sticks the first couple times after they bought a Sony, but eventually got that working.

    I really hope someone does a followup paper (even white papers from one company touting the superiority of its approach to the other's) comparing these. Also, if they could explain whether RGB or CMY is better for sensing light, anyway. My gut instinct is that RGB should be better, because my junior high art teacher and high school physics texts say that light uses RGB and pigments use CMY, but surely Nikon must know something more.
