Not to be rude or anything, but working in the ABQ area as well we have hired a few people who applied to Stellar Science, they have said they were just asked to submit a sample of work and never heard anything back. One or two of them my have been a bit bitter over it since they worked hard on their submissions. What exactly are you guys looking for or have your hiring standards changed or what usually leads to candidates not being hired.

This may sound like I applied and was burned, but I can assure you this wasn't the case, it just came up twice recently and a lot of people had gripes.

It's equivalent to 3-clause BSD.

My comment as may be noted was more a commentary on the historical licensing of MINIX which lead to Linux, see the original post.

Interesting article, seeing the history of optics being settled over a near millennia is quite breathtaking and reveals a lot about the nature of scientists.

What I wonder is why some of them chose not to publish their works when their hunches were correct?

What have you published? Or have most people?

LOL, how could two "emeritus professors" write an article like this without a single mention of the Mayan civilization, which is regarded by many as the earliest use of an explicit zero in a numerical system. Are they not aware of this?

melissalobos · 3 years ago

Not sure, but maybe because it isn't a positional zero.

Why not MINIX?

melissalobos · 3 years ago

I don't know quite what you mean? MINIX isn't free, which is pretty big for a student project. In fact people may have started a similar project(not big like GNU) to due to its price.

I was hoping to see "build your own virtual terminal emulator". But alas! Anybody have a suggestion?

Check the article’s discussion of rendering bugs and implementation incompatibilities.

melissalobos · 3 years ago

Sure those were encountered there, but at least in my experience those are easily avoided. I have had to make test suites for this, and in my experience if you use reasonable libraries things work well.

You want to see obfusication? Check out FreeSlots.com. Look at view source on one of the slot machines.[1] Can anyone decode this and figure out the odds generator?

To answer your question, yes. Someone absolutely can decode that and figure out the odds. If they couldn't then there would be less obfuscation used. A browser ABSOLUTELY has to be able to run the javascript. Anyone dedicated enough can de-compile that javascript to a program. Is it easy? No, but people do it all the time.

I have had to deal with client that thought they could keep some bit of code secret on a browser before. I have had to explain many many times that anything the browser can do a human can do. So if a browser can run the code, at some point a human can too.

I decided to use JPEG 2000 to save disk space on my photo archive a decade ago... huge mistake.

[edit] I thought I had the originals backed up on CD, it turns out I didn't.

DigiKam and many other programs don't support them natively.

At some point I'm going to have to write a script and convert them all to normal jpegs.

melissalobos · 3 years ago

Why was it a huge mistake? There are decent libraries that support it. Did it just not work with your cloud setup or OS libraries?
