I’m interested in hearing your about your dependency issues, either via PM or here in public. Maybe I can offer some insight or succor, or get something fixed.

I was thinking you could try using stackoverflow.com points as one indicator of rep on anyfu. They have an api and it could prove helpful especially in the early stages when people haven’t got reviews yet. [**just an idea, I don’t have any association or even very many points on stackoverflow/stackexchange]

PS: I have been listening to your podcast since episode 50 or there about’s, Keep up the great work!

My main takeaway from this show: “The best job stability you can have is constantly developing and evolving your skills with the latest and greatest technologies. ” – Jay Rob

Thanks for the links! Looking forward to the next episode 🙂

Perhaps you could put together a Techzing Sountrack cd as a fundraiser? (Maybe you could guilt Alex into contributing some tracks as well). I would buy a couple.

This gave me an idea: anyone want to create a url shortener that uses Kanji and other glyphs? You could make much shorter URLs 🙂 Mind you, it seems that twitter has introduced its own shortened into the web interface now, so I wouldn’t want to be competing against that!

p.s: what’s with the lack of links in this blog post? Methinks you must have been telling the truth about being super busy!

Fit with two hours of aerobic exercise is between 84 240 and 110 640 heartbeats/day. (Previous post used 20 hours not exercising instead of 22)

If that’s the case twitter would really have a different dynamic for Japanese people. I mean this blabbering comment is under 80 words :-p

What’s the story morning glory?

Since it looks like SQL is well covered, I thought I’d chime in on the idea of “the Singularity” as I find it really interesting and can’t help myself.

The main thing that I have picked up about the Singularity (and whence the name is derived from) is that accurately predicting what will happen beyond the singularity is impossible. It is a point in time where something allows technology to advance at such a rapid pace that the implications for human society are impossible to predict. There are many different potential triggers for the Singularity, but they all involve the arrival of super intelligence. Things like the development of the first real Strong AI, genetic enhancing humans, neural interfaces to computers, ET landing (I’m looking at your Jason!), time travel and nanobots spring to mind.

The name Singularity is derived from using a black hole as a metaphor to describe this event. With a gravitational singularity (effectively black hole) there is an event horizon beyond which it is impossible to see anything and the traditional laws of physics break down.

So, whilst our technological progress in our understanding of biology may be linear, there are other options that might bring it about.

Fascinating to think about, but also very frustrating because by it’s very definition you can’t think about it too much! 🙂 Something your touched on is whether or not it’s going to be a good thing for humanity or bad. Should we be trying to delay it or rush towards it? I think it is inevitable, either that or we end up destroying ourselves completely with no resulting output.

A person in shape will have a lower average resting pulse for the 22-23 hours not spent working out, than a person not in shape.

A quick DuckDuckGo search (http://bit.ly/aOesyy) suggests that a resting heart rate of a fit person is between 50 and 70, and the resting heart rate of an unfit person is between 80 and 90.

Unfit, no exercise:
(80 to 90) bpm * 24 hours = between 115 200 and 129 600 heartbeats/day

Fit with 2 hours aerobic exercise per day:
(50 to 70) bpm * 20 hours + 152 bpm * 2 hours = between 78 240 and 102 240 heartbeats/day

Assuming constant heart rate for the whole period when not exercising (climbing a flight of stairs or doing other similar daily activities would increase the unfit persons heart rate more than that of the fit person). 152 bpm for exercise is 80% of maximum heart rate for a 30 year old person (http://bit.ly/qM9ee6).

So I guess I’ll be seeing you in the gym then Justin.. 😛

Many fields in MySQL have a character set / collation. How character count and byte count relate depends on that.

CHAR and VARCHAR differ on the way they are stored.

CHAR(10) will always consume a constant amount of memory, where _ is clean (wasted) memory:

__________ An empty CHAR(10)
hi________ hi stored in a CHAR(10)
abc_______ abc stored in a CHAR(10)

So use CHAR when your values basically have the same length. Language codes, hashes …

VARCHAR(10) will look like this in memory:

0| An empty VARCHAR(10) field
2|hi hi stored in a VARCHAR(10) field
3|abc abc stored in a VARCHAR(10) field

(Ofcourse that prefix are two reserved bytes and there is no |)

That means that VARCHAR(200) wouldn’t require more memory for the same values. Use VARCHAR for text that differs in length, such as tweets.

TEXT depends hugely on the storage engine. Text isn’t (of course it is, but it can be loong) limited in length. Text will be stored outside of your actual table and referenced from there. Use VARCHAR if you can.
