Comment: There are still a lot of Perl shops (Score 2) 269

See http://jobs.perl.org/

A couple of years back, I was trying to hire someone ... although we were hoping for OO Perl skills. We ended up hiring someone with database skills to train up in Perl, instead.

The problem with age isn't so much that you have less portable skills, it's that you have a less portable life -- if you have a sponse & kids, you don't want to move the kids in the middle of a school year and away from their friends ... if you have a spouse, you have the problem of trying to find a place that's convenient for both your jobs.

If you're single with no kids ... Booking.com is hiring in the Netherlands. It's effectively an English speaking country these days (although it's been 30 years since I've been there).

(I have no affiliation with booking.com, other than they were a sponsor for many years of the DC-Baltimore Perl Workshop, which I help to organize)

Comment: What is with the hugging? (Score 2) 68

It's not just you -- the article had a quote that makes it seems like there's an unknown sysadmin care bear:

Culturally, we have to make this shift from a mistaken belief that all our data has to be near us and somewhere where I can do and hug the server, instead of someplace where I don't know in the cloud. This is a big shift for many within the department. It's not going to be an easy transition.

I don't know about you, but we don't have our racks just standing their on their own ... they're in rows, so you'd need rather long arms to try to give anything a hug. Maybe the one on the end of the row, but that's still a four or five foot deep rack ... so no hugging if you're short without unracking the gear first.

Oh ... and I've learned to ignore the 'number of data centers consolidated', after it was declared that every wiring closet was a 'data center' in our agency (not DoD), and those were going to count against the 'must close (x%) of data centers'. We 'consolidated' by having two rooms next to each other, so that electrically and AC wise, they're the same room ... but for physical security and access control, it's two separate spaces.

Any vehicle with airbags in it has a data recorder so that the manufacturer can determine under what conditions the air bag did or didn't go off.

So even if you don't have a dash cam, if you're in an accident, get the data from the other vehicle. Depending on the make & model, you might need to make sure that the vehicle doesn't get driven before the data's been read out.

I was once driving home on Thanksgiving day a few years ago -- taking I66 to the DC Beltway. It wasn't rush hour, so I waited until the sign came up that marked that it was now an exit lane (the shoulder is an extra lane during rush hour). It seems that there was some guy *flying* down the lane ... and so he must've considered me to have cut him off.

Once we got to the exit (which had two lanes), he shot around me, then pulled into my lane and slammed on his brakes. When I stopped without hitting him, he gunned his engine, we both got back up to speed ... then he stopped again. I had to stand on my brakes this time.

I kinda wished that I *had* hit him, as I could've proved that it was his fault for wreckless driving. (although a dash cam would've have hurt -- show that he had no reason for braking, as the road was clear, and that he had intentionally gotten in front of me to try to cause an accident).

You can be a programmer and write documentation, but if you want good documentation, the person writing it shouldn't be the same person who wrote the code.

The problem is that you're already too far in -- you understand the design issues, the quirks, etc. You need someone with a fresh view to write the documentation who doesn't come in with a lot of implicit knowledge of the inner workings of the software.

My boss has a policy that it's the newest or youngest person on the project's job to write the documentation, for that very reason. (the others still review it, but they write the first draft).

Could this be an emerging Earth Sciences turf war between NOAA and NASA? Lately it seems more of a National Atmospheric Space Administration. Mission creep, much?

Nope, it's fully in compliance with the 2013 OMB memo on an Open Data policy. The subheading on that memo is 'Managing Information as an Asset', and there is a real lack of a comprehensive catalog of NASA's data. (note that this is *not* the same as the 2013 OSTP memo on public access to federally funded data, but they're related.)

Even with the re-design of data.nasa.gov, the content behind is is woefully incomplete. When I contacted the creator of the page years ago, he said that they just did some internet searches to find 'data', and then listed them. They were listing websites that mentioned data, not even breaking it down into missions & investigations.

Someone needs to go through and determine for every investigation from every project what data *should* be there, and figure out if it's online, if it's in a dark archive, if the PI still has it, or if it's missing. They should catalog it according to GEMS and possible DataCite (although assignment of 'creator' for the data might be something that needs to be resolved by each science community)

I had tried proposing something to the NASA IT Labs call shortly after the memo came out, but the people running it were blocking our network from being able to submit. I tried again in 2014, and they gave me an alternate way to submit, but they took weeks to get the work-around, and by then I was out of town for a meeting.

by oneiros27 (#49436231) Attached to: Bell Labs Fighting To Get More Bandwidth Out of Copper

Back in the 1990s, I was working in Kentucky for an ISP and doing assorted contracting work.

I had a case that was rather similar what you're describing, only ours wasn't run that way because of incompetence -- we were connecting up all of the offices of the Department of Public Advocacy, and for one location the state had decided that rather than get a new line to the DPA offices, as they were in the back of a shopping mall that already had some government offices in it, we'd get fibre pulled between the two offices. Mind you, this was frame relay and fractional T1 days, before DSL, so a new drop was pretty expensive. (I want to say it was around $500/month for just the line charges for a T1, not including the port charges to the ISP tht you were connecting through).

So, when we went there for the install, someone had already pulled the fibre -- I went on the 3 hr drive down there, got soeone to escort me to where I needed to go, and plugged in all of our gear, then went and set things up on the DPA side.

All was fine for a year or so, then we got a call that things were down -- we tried everything that we could over the phone with non-IT folks (it's an office of lawyers), so I was sent on the 6hr round-trip with spare fibre patch cables and such.

A quick check in at the DPA offices showed nothing wrong over there, so I went over the other end of the bulding. I don't remember what the name of the department was, but it was a sort of family services type thing (where people got food stamps, stuff like that). I went up the counter and told the person behind the plexiglass that I was with DPA, and we had equipment in their wiring closet that I needed to get access to.

To which she replied, 'DPA is around the corner'. And I said no, I work for the DPA, and I need to get into your wiring closet. And she kept repeating that DPA was around the corner. I asked for her to get someone else. And I waited 10 minutes or so for someone else to come out front. Once she showed up, I spent a few more minutes with the 'DPA is around the corner' response until I *finally* got through to her and convinced her to let me into their closet. (mind you, this would likely have been considered 'social engineering' if I did it today, as I showed them no ID, being that I had none that said I did work for the DPA).

When I finally got to the closet, I saw that our box had no lights on it ... I traced the power cord down to a power strip that someone had removed all other things from, and taped over those outlets and written 'BAD' across it ... yet left our fiber tranciever plugged into it. I think I was in the room for all of 5 minutes -- it took me *way* more time trying to talk them into letting me in the room than to actually diagnose the problems *including* the time spent in the other offices.

So ~6.5 hrs to fix a problem, because the other office didn't care at all about our gear in their closet, as it would've taken them less than a minute to have moved everthing that was plugged into the known-bad power strip.

So I'd have to say -- no way in hell should you run cable to a private office. If nothing else, that office might close or move, and who knows what might be in there next (or if the new tenents want to remodel it).

Comment: This is new? (Score 1) 121

Admittedly, it wasn't specifically a CompSci class, but when I took our engineering school's 'Intro to Programming' course, we were paired up for the assignments. The only rule was that I wasn't allowed to pair up with Sebastian, as we were the two who had significant programming experience before we got to college.

When I took Numerical Methods my sophomore year, we were paired up in class, but that was partially because the computer lab we worked from didn't have enough computers for all of us. When it came time for the final, they had to book a second lab so that we'd all have computers to compile on. (which meant those of us in the room w/ newer machines had an advantage over the other room, as our code would compile in 1/2 the time)

But let's face it -- group projects are pretty typical in college. And pairing up for labs is normal too ... we don't accuse chemists of getting 1/2 an education if they didn't do every last titration themselves, or a geography major of getting 1/4 an education if they have 3 people in their study group.

The goal is get the people to learn the materials -- if done right, the two people learn from each other. Yes, it can be a drag if you get an idiot for a partner ... but unlike in high school, the people who know their stuff are in demand for their skills, not looked down on for being a nerd/geek/whatever other disparaging term.

If you have two people making forward progress then it's better than one person struggling along and getting nowhere. Maybe I'm being a bit socialist in my views, but there are sometimes when we need to step away from the 'everyone for themselves' typical American attitude and look at the nordic standards for schooling. You don't want your school to get a reputation for being the one that produced someone who screws up in some major way. My undergrad is in civil engineering -- and if I find out I'm in a building that one of my classmates worked on, I'm going to leave ... immediately.

As the government isn't allowed to spy on citizens without a warrent, under normal circumstances, the satellites aren't supposed to take images when over the U.S.

So the government instead buys images from commercial vendors ... the same folks who provide images to Google and Bing for their mapping projects. (which admittedly, might not be as high of resolution).

I'm thinking that there needs to be a line drawn, otherwise all you end up doing is having a way to make an end-run around the legal verdict -- "we'll just spin off a company that does what we're not allowed to do, and buy the results from them".

He mentioned that less than 24hrs after its release, they already had more Parkinsons patients signed up than any published study on the disease.

If the watch can get *any* sort of medically useful data, I'm all for it, especially as so many people have been designating that their data can be used by any qualified researcher. (yes, there will still have to be IRBs to approve research at most institutions, and I assume some sort of gatekeepers from Sage Bionetworks to determine who gets access to the data). ... but the fact that we might be able to get medical data at a scale never before seen is huge. And we might get a wider slice of the population, not just college students or from a limited geographic area that might not be applicable to the larger population.

When ExtJS changed their license to GPL3, not LGPL, as you would expect for a library.

The owner of Sencha then put out a statement that if you built something that made use of ExtJS, then you had to release your software under GPL3 ... including the server components.

I have no problem with releasing the client side -- that's all javascript that people could view the source and see ... but releasing the server side? That requires security audits and a review by legal ... it's just not going to happen.

Reading the review, the reviewer seemed to have the same take on what GPL meant from the statement :

With MySQL, on the other hand, the client library is GPL, so you must pay a commercial fee to Oracle or supply the source code of your application. (Thatâ(TM)s less of an issue when using MySQL in websites; MariaDB uses the GPL 2 license but also has a less restrictive LGPL license for MySQL Client libraries.)

Now, if the issue is simply the *client* code, then you could get around it by using ODBC, or something like Perl's DBD::mysqlPP, which doesn't use the MySQL client code. Do you have to release the whole application if it's just something that makes use of a mysql database? I don't know, but with all other things being equal, and more and more people coming to this conclusion, I'd rather just stick with something that's LGPL or MIT.

HTTPS would require additional CPU for the SSL processing and bandwidth because it would make requests non-cacheable.

Not to mention that it would make the intrusion detection system attached to the router completely useless, so we'd lose a layer of security and it would make it more difficult to detect probing across the network and other 'slow' attacks. It would also prevent us from doing auditing after an exploit is known but before we've been able to get the mod_security rules in place or whatever other mitigation.
