An interesting conversation at work today. I was talking with the guy, L (no – a different one), who has been responsible for our IT for the past 3.5 years. L isn’t the guy that always does the work, although he can. His real job is as an engineer in the company and that’s his primary focus. However, he does handle the technology strategy and monitors the folks that do the IT work. (He and I are talking quite a bit since I’m trying to take some of the load off in this area). ...
Last week at work was pretty interesting. On Tuesday, L and I flew up to Dayton for the day to meet with our sponsors. That meant a 6am flight out and originally a 11pm return flight. Fortunately, we wrapped it up a bit early and landed home back around 8:30pm. The meeting went well. We were presenting some ideas that I had to the sponsors and they seemed to like them. Strangely enough, in talking to L, he said that he hadn’t really understood what I was proposing until the meeting. Not bad for a guy who wrote a short paper for the sponsors that described what he didn’t understand! But then, I guess that’s why L’s a full professor 🙂 ...
One of my projects at work involves information markets: tools to extract aggregate knowledge from groups of people. For example, at Intrade, you can buy and sell contracts on questions like, “who will be the democratic nominee for president? or “how likely is it that the US economy will slip into recession? The market price reflects the cumulative belief that a given event has a certain probability. IEEE Spectrum also recently did a piece on information markets which talked about Microsoft’s use of a market in 2004 to predict the likelihood of an internal product meeting its production schedule. By opening the market to its employees, who presumably had knowledge of the issues with the product, Microsoft predicted that it would ship three months late – which it did. ...
Right before Thanksgiving my iPod went to that great electronics superstore in the sky. More specifically, the cute little 1.8″ hard drive died. Having looked around, I figured the best (or at least most interesting) fix was to replace the drive with a compact flash card. The connector part finally came in today and we had a lovely (and to spare you the suspense, successful) operation. We started with a 30 GB 5th generation iPod video showing the unhappy ipod symbol: ...
Over the holiday (I hope everyone had a good Thanksgiving!) I spent some time figuring out what to do about my broken iPod hard drive. The simplest/cheapest thing is to replace the drive with another 30 GB 1.8″ drive. The problem is that this is boring. Okay, next thought – up the drive size. I can get a 40 GB drive that’s the same size and is a drop-in replacement. Only problem is that this isn’t very cost effective in terms of dollars per GB. Apparently the wide-spread use of 30 GB drives in iPods has lowered the price point here. What about a 60 GB? It looks like that’s doable too and at a good price point. Downside is that I need a new back to accommodate the thicker drive. Hrm, that’s no good either. ...
A couple of weeks ago, Hunter and I were talking about passwords. More to the point, the inadequacy of passwords and why we haven’t moved beyond them yet. This touches on several points that I made last year. Specifically, that a password that is secure enough starts to restrict its usability. In a nutshell, authentication is proving that you are who you claim to be. The standard ways of authenticating yourself are through: something you know (e.g., a password), something you have (e.g., a token) or something you are (e.g., biometrics, facial recognition, etc.). So the claim here is that the human brain is not good enough at remembering things to make “something you know secure. Unfortunately, it’s cheap and easy to implement. Two things which are always important. ...
I’m starting to think that there aren’t any good Internet service providers. hsarik had troubles with Rimu Hosting. My own ISP seems to be far more focused on (their own version of) security than on usability. At work we’ve been using Pair. I’ve been pretty happy with them until this afternoon around 5pm when our project went dead while we had some 50 people using it. When we first developed the project, Pair was using php4 (yeah, I know – it’s my own fault for using php 🙂 ). Fortunately, they also provided phpwrap to allow cgi access. Okay, that’s not great, but it at least let our project which required php5 go live. Sometime recently, they made the default php5 without phpwrap. If I had known, well great – but I didn’t see any mention of it. Today, right after I went home they broke phpwrap. Easy enough to fix, but still irritating.
From skvidal. If you haven’t seen powertop yet, you’ve got to look into it. Arjan van de Ven, one of the linux kernel hackers and an employee of Intel, released powertop back in May. What is powertop? Think of the Unix “top, but monitoring power, not CPU, usage. It tells you how long you are spending in different CPU states, how long at different CPU frequencies, what is waking up the CPU most frequently, and best of all, it makes recommendations for saving power. ...
K thinks I’m a freak. In her defense, I’m not certain that she would have ordered a $70 keyboard, so she may be right. In my defense, I bought my first IBM-clone in 1990 and have kept the keyboard I chose since then. The company I bought it from, Formosa Computing (for those of you in NC, think Intrex), assembled parts and sold white-box computers. The keyboard that they originally gave me was awful. I didn’t like the mushy keys, so I went back, tried a dozen different keyboards and finally exchanged it for something with a bit more tactile response. With every new computer I bought, I used this keyboard. At one point, it had an AT to PS/2 to USB adapter in order to get it working. ...
Working in IT, one of the things that is often on my mind is backing up my data. It’s often on my mind, but I seldom do anything about it. A few years ago, K and I bought an external USB drive to which we occasionally sync our desktop. That made me a bit more comfortable, we’re now covered if the drive crashes. Of course, I then started worrying about a fire in the house. Since my external drive is sitting on top of the computer itself, anything that destroys the one will likely destroy the other. ...
