The Guardian on migrating from Mongo to Postgres. It’s interesting to read about implementing a major database change like this with no downtime.
I just finished reading Broad Band: The Untold Story of the Women Who Made the Internet by Claire L. Evans (h/t @boop). I thoroughly enjoyed it, and learned quite a bit. I’m also a sucker for computing history, and remember things like gopher, so your mileage might vary.
Lou Montulli, a former engineer with Netscape, writes about the origins of the blink tag. It seems that it was a lament for the lack of features in text-based browsers.
Back in 1994 I was a founding engineer at Netscape, prior to that I had written the Lynx browser, which predated all of the other popular browsers at that time. Lynx had been and still is a text only browser and is commonly used in a console window on UNIX machines.
Sometime in late summer I took a break with some of the other engineers and went to a local bar on Castro street in Mountain View. At some point in the evening I mentioned that it was sad that Lynx was not going to be able to display many of the HTML extensions that we were proposing, I also pointed out that the only text style that Lynx could exploit given its environment was blinking text. We had a pretty good laugh at the thought of blinking text, and talked about blinking this and that and how absurd the whole thing would be.
Saturday morning rolled around and I headed into the office only to find what else but, blinking text. It was on the screen blinking in all its glory, and in the browser. How could this be, you might ask? It turns out that one of the engineers liked my idea so much that he left the bar sometime past midnight, returned to the office and implemented the blink tag overnight. He was still there in the morning and quite proud of it.
Why am I not surprised that the idea originated in a bar.
We never thought a video would be watched in numbers greater than a 32-bit integer (=2,147,483,647 views), but that was before we met PSY. “Gangnam Style” has been viewed so many times we have to upgrade!
Hover over the counter in PSY’s video to see a little math magic and stay tuned for bigger and bigger numbers on YouTube.
Earlier this year, Google’s Gmail service fixed itself before the engineers did. From the post-mortem blog post:
Users began seeing these errors on affected services at 11:02 a.m., and at that time our internal monitoring alerted Google’s Site Reliability Team. Engineers were still debugging 12 minutes later when the same system, having automatically cleared the original error, generated a new correct configuration at 11:14 a.m. and began sending it; errors subsided rapidly starting at this time.
Found this sifting through some old bookmarks, hat-tip to Kyle Neath.
We rescued two PDP-11/34 computers and their associated equipment from a storage unit in the Bronx and have been working on getting them running again. The computing system included multiple RK05 hard drives, two RL02 decpack drives, a TU11 tape drive and tons of media, including “digitized monkey brains“.
Unsurprisingly, the operating system is not y2k compliant.
Tim Harford takes a look at big data for the Financial Times and asks if we are we making a big mistake.
But the “big data” that interests many companies is what we might call “found data”, the digital exhaust of web searches, credit card payments and mobiles pinging the nearest phone mast. […] As our communication, leisure and commerce have moved to the internet and the internet has moved into our phones, our cars and even our glasses, life can be recorded and quantified in a way that would have been hard to imagine just a decade ago.
I think the main take-away is that there’s a need to be careful with the data and not jump to conclusions, just because you have a lot of data, doesn’t mean it’s good. I also think it’s important for these companies to allow us, as consumers, to access our data in the same ways that they’re able to.
As a side-note, I came really close to not posting this link because of scuzzy clipboard hijack behaviour from FT. I copied the above text to use as a quote. Upon pasting the quote, they attached a wonderful message about the effort that journalism takes and to use the link to share instead. That’s exactly what I was doing, and despise the insinuation that I somehow disrespect the efforts of journalists by copying a paragraph of text.
Microsoft released the source code to MS-DOS v1.1 and v2.0
Here’s a somewhat fluffy NYT Magazine piece from Daniel Engber, titled Who Made That Progress Bar? He credits it to an interface designer named Bob Stahl. I found this tidbit interesting:
Myers asked 48 fellow students to run searches on a computer database, with and without a progress bar for guidance. Then he had them rate their experience. Eighty-six percent said they liked the bars. “People didn’t mind so much if it was inaccurate,” Myers says. “They still preferred the progress bar to not having anything at all.”
It lets the user know there’s magic happening behind the curtain.
1×1.gif should have won a fucking Grammy. Or a Pulitzer. Or Most Improved, Third Grade Gym Class or something. It’s the most important achievement in computer science since the linked list. It’s not the future we deserved, but it’s the future we needed (until the box model fucked it all up).
All the things I’ve forgotten. Blink, deal with it.
