Scraping the Bottom of the "Developer Productivity" Barrel

Patrick Smacchia writes a blog post about how buying a Solid State Drive will produce a worthwhile increase in developer productivity.

He cites a few self-run benchmarks. A couple are impressive: a certain build shaves off 2 minute and 14 seconds (a little under 50% faster), and running 1846 NUnit tests brings a 2 minute and 40 second process down to 37 seconds (about 80% faster). The rest... not so much. Most are cutting scant seconds off of already quick processes.

I do believe that there are some expenditures that are worth it. Developers spend 8 hours a day sitting, so buying them extremely comfortable chairs makes a huge difference. Similarly, developers spend 8 hours a day looking at their monitors, and buying them each two large monitors allows them to keep their work and minds better organized.

This SSD claim does not seem to pass muster. Look at the difference. An internal 80GB Intel SSD costs $559.99. How much does a normal 5400RPM internal 80GB drive cost? Well, I can get this Western Digital one for just over $40.00.

That means the Intel one costs almost 14 times as much. If I'm buying this for my developers, I want to make sure it's cost-effective. Let's say I pay my developers an average of $52.00 per hour (to make the numbers easy). That means, to justify the extra $520.00 I'm spending to get this SSD, it needs to save them 10 hours over the course of their time with me. That's 268 of those builds mentioned earlier, or 293 of those sets of NUnit tests.

Is this an outrageous number? No. But it's also not an obvious win, like buying a pair of large monitors or a comfortable chair. It's scraping the bottle of the barrel, to say the least. Unless he's got a super awesome chair, a couple 24-inch monitors, and all the other productivity staples, I'd say his money would be much better spent elsewhere.

Great Analogy for Entrenched Social Norms

I'm stealing this analogy from a blog post by core Django contributor James Bennett. I think it's brilliant:

There's an old joke, so old that I don't even know for certain where it originated, that's often used to explain why big corporations do things the way they do. It involves some monkeys, a cage, a banana and a fire hose.

You build a nice big room-sized cage, and in one end of it you put five monkeys. In the other end you put the banana. Then you stand by with the fire hose. Sooner or later one of the monkeys is going to go after the banana, and when it does you turn on the fire hose and spray the other monkeys with it. Replace the banana if needed, then repeat the process. Monkeys are pretty smart, so they'll figure this out pretty quickly: "If anybody goes for the banana, the rest of us get the hose." Soon they'll attack any member of their group who tries to go to the banana.

Once this happens, you take one monkey out of the cage and bring in a new one. The new monkey will come in, try to make friends, then probably go for the banana. And the other monkeys, knowing what this means, will attack him to stop you from using the hose on them. Eventually the new monkey will get the message, and will even start joining in on the attack if somebody else goes for the banana. Once this happens, take another of the original monkeys out of the cage and bring in another new monkey.

After repeating this a few times, there will come a moment when none of the monkeys in the cage have ever been sprayed by the fire hose; in fact, they'll never even have seen the hose. But they'll attack any monkey who goes to get the banana. If the monkeys could speak English, and if you could ask them why they attack anyone who goes for the banana, their answer would almost certainly be: "Well, I don't really know, but that's how we've always done things around here."

Best Virus Email - Ever?

I just received this email (I don't recognize the sender):

Subject: Fw: ALERT, ALERT HUGE VIRUS COMING !!! PLEASE READ & FORWARD !

Please be advised.......I just received this from a friend and checked it out. It is for real.
I strongly recommend that you pass this along to your friends and those on your e-mail list.
Doug

    I checked with Norton Anti-Virus, and they are gearing up for this virus!
     I checked Snopes , and it is for real!!
     Get this E-mail message sent around to your contacts ASAP.
     PLEASE FORWARD THIS WARNING AMONG FRIENDS, FAMILY AND CONTACTS!
     You should be alert during the next few days. Do not open any message
    with an attachment entitled 'POSTCARD FROM HALLMARK,' regardless of who sent
    it to you. It is a virus which opens A POSTCARD IMAGE, which 'burns' the
     whole hard disc C of your computer. This virus will be received from  someone
    who has your e-mail address in his/her contact list. This is the reason
     why you need to send this e-mail to all your contacts It is better to receive
     this message 25 times than to receive the virus and open it.
    If you receive a mail called' POSTCARD,' even though sent to you by a
    friend, do not open it! Shut down your computer immediately.
    This is the worst virus announced by CNN. It has been classified by
     Microsoft as the most destructive virus ever. This virus was discovered by
    McAfee yesterday, and there is no repair yet for this kind of virus.  This
     virus simply destroys the Zero Sector of the Hard Disc, where the vital
     information is kept.
     COPY THIS E-MAIL, AND SEND IT TO YOUR FRIENDS. REMEMBER: IF YOU SEND IT
    TO THEM, YOU WILL BENEFIT ALL OF US

I really want to see the code of this virus that "burns" the hard disk. It sounds awesome.
