I cannot tell you how much I thank questions. All of them, even the dumbest.
I do try to be very clear and dynamic, but some topics... are just hard to grasp, or I have not found the proper way to teach them... But in some subjects, most students won't even realize they are not getting what I teach. There are a few students who are burnt with questions, and cannot stand on a point they don't understand. Some students insist on their questions even if they are sometimes just too easy.
I thank them. And I try to explain, over and over, from different angles. That's what brings back the attention of the rest of the class, and the different angles are in the end good for all of them.
Yes, they are free. But the scientific world revolves around the notion of the different metrics to your work. And it's not only prestige: Often, your income level will be determined mainly by the impact factor of the magazines you publish in.
But... Guess who dictates the values for said impact factors in the international indexes?
Of course! The publishers of closed sciencie magazines.
I teach "Operating Systems". And yes, I don't expect (I'd love, though!) many from them to have to implement a Second-Chance (Clock) memory page replacement algorithm. But I do expect them to understand how duing professional their lives the programs they write will be treated by the operating system, and how to avoid bad performance resulting from inefficient patterns.
The people complaining in the media about 150k debt for 4 years of school are either lying, actually had post-graduate education, or made extremely poor and lazy decisions (and I count going to a $$$ private university as a poor decision if you have zero financial aid). Its not even easy to get 150k in loans. You can't get that much from federal loans...and private lenders aren't so favorable to slacker kids who can't even bother to earn a single dollar all 4 years.
That's also a very striking fact. Practically all of the people I know that work on postgraduate studies in the best universities in the country not only do it without paying tuition, but getting a scolarship (around US$1000-1500 a month, roughly the salary they would get as professionals). The logic is, postgraduate studies do require you to focus full-time on them, and not giving them that attention will lead to failure. The whole society will benefit from masters and doctors, so the whole society pays for them. Of course, academic requisites for permanence are high.
If the society and government do not value having skilled professionals, sick schemes where graduate students have to spend their evenings serving at restaurants, and can devote much less to their studies. That's a losing recipe. And of course, that leads to longer terms because of failed subjects, which means increased debt.
I am a teacher at a public university in Mexico. I know many of my students work (and, of course, many don't) to get enough income to live (maybe because their parents cannot support them, maybe even because they support their family).
What I completely fail to understand is how on Earth can a 22-year-old graduate –as you say– with US$150K in loans. That is just insane. And sick.
In my country, as in most of Latin America, and (as far as I understand) in Europe, all of the best universities are State-run, and tuition is either free or really low — Of course, there are private universities, with first-world scolarships. They have some selling points, but with very few exceptions, they are basically little but diploma mills, and next to no research at all is done in them (just teaching).
Anyway, I cannot understand how the USA cannot have a decent public university system. I know there are *some*, as part of my family have graduated from them. But just the idea of being in such a deep debt as a freshly graduated student... Makes me sick.
You made me immediately think on the poor Lemmings looking at the decreasing counter on the top of their heads, only to grab their heads in distress upon reaching zero... Exploding in a gory feast of blood, leaving their poor mammal corpse for their brethen to remind them of their probable fate.
One of the cruelest games in game history. But, yes, one of the best ones as well.
Oh, come on... I have also lost several items only to find them later, misplaced in the most obvious places. Of course, I have also attributed to theft some of my losses. I guess that I have misplaced my stuff more than once.
So, if thieves were to end up with a useless brick, would people lose less phones?
Do thieves only get phones to resell them (and not, say, take your contacts information, for blackmail and similar stuff?) In my country, there have been countless campaigns telling people not to fall for anybody saying "I have your daughter kidnapped", because they are most usually bluffing (and demanding for expedited money transfers, to which many distressed parents comply without first checking)
I seriously seriously doubt this US$580 million figure would be in any significant way reduced
(...)to say Ray Kurtzweil is just some "foolish expert" is to be utterly clueless (...) he probably did more before breakfast this morning then you will achieve in your entire life.
You mean, like having some nice morning sex? Given the Slashdot famed population statistics, you might be just right.
In the 1860s, Brazil, Argentina and Uruguay allied in a war against Paraguay. This war caused the death of ~60% of the Paraguayan population, including ~90% of its adult males. The social effects are still present today, over 140 years later: The country is the most machist in Latin America (which is not an easy feat!), because it became not only normal but positive for a man to have several women. Of course, it also destroyed Paraguayan economy, and to this day, Paraguay is the poorest country in South America. Of course, this says very little of what would happen by killing all mosquito males or females. But since when does a Slashdot discussion need to stay on topic?;-)
Please note that "a woman" for the Slashdot demographics most likely includes "mom", and up to a certain point of demographics, "granny". Besides that... I doubt most aunts would trust Slashdotters' color sensibility. I mean... Just look at your desktop!
Expanding a bit from my previous post: Of course, interested kids will get their RPi going, and might end up making magic, just as many of us did with our 8-bit machines 25 years ago. However, the bar the OLPC set to itself was quite different — And might I say, much higher: To come up with a {product, system} that's made for kids. For all kids. To help them to learn about everything, not just about how to do I/O with a computer. An operating environment that's tailored to a constructuvist view of education, allowing them to (easily) understand what's going on in the programs — But even if they don't want to, give them a wide array of programs to hand-hold them through the whole educational process.
Not by far the same task. Both RPi and OLPC set on for extraordinary tasks. But their targets are very far from each other.
Cheap it is, granted. And yes, its inceptors do (try to) target it at the educational market. I have in fact spotted several RPi machines at my university. However, getting a RPi usable to be part of a general science project is quite far from trivial. Yes, given its easily accessible GPIO, it's close to ideal. But basic and high school teachers rarely know enough to get a RPi to boot, don't even mention to control or monitor outside events.
In Mexico, at least, shopping in the known ideologically-green stores is often much more expensive than in regular chain stores (i.e. Walmart and the like). I buy most of my fresh food in the street markets, and it is both quite cheaper than chain stores and of better quality (i.e. food lasts longer, there is a wide range of product qualities on different price points for each produce, etc.)
Now, there are *some* producer-direct organic outlets which are quite cheap, and with great quality... But of course, it's not so easy to get to them (they are often in the countryside, for obvious reasons, and my city is quite big for me to leave it every week or two).
And Chileans do know at least a bit of chilli (unlike their Argentinian neighbours). But barely enough. Their food is thankfully quite tasty by itself. But, as a Mexican, being in Chile and not being able to find any real chilli... Was quite odd.
There is a file called documents/My Clippings.txt if I'm not mistaken. Some time ago, I wrote a simple program (kindleclip — https://github.com/gwolf/kindl... ) that presents you highlights, bookmarks and comments, allows you to search, either by book or by date. It's a GTK2 project built with Glade however, and I have not yet ported it to use current alternatives, but at least I believe the source to be quite readable/followable. Hope you find it useful.
I got my first Acer (marketed in Mexico under the "Printaform" brand, but manuals were all branded Acer) in 1987. The Acer 5201/5203 (single- or double- floppy drives) were quite popular here in Mexico by then.
"Simple" PC clones, built on a passive ISA backplane. The motherboard was just a "special" ISA card with the CPU and the 256KB of RAM in it. First expansion slot had a CGA card, second expansion card was the I/O controller, and it had one free port (to which I eventually hooked up a MFM controller and knew the bliss of having a hard drive).
No, it won't make much sense even with that in mind. Even less, in fact.
Embedded systems are usually factory-installed. In the factory, they don't do the installs via floppies. Most OpenBSD installs today are done off their (very good!) CD-ROM media, or maybe even more, by USB.
Floppy disks are used for a tiny percentage of installs (yes, even of *their* installs). Alright, they don't want to dump very old architectures that are known to work and have no other acceptable bood medium, but in the end... Basing the entire OS in the least common denominator takes a toll on the general usability of the system in everyday settings.
That MySQL's space was/is being transferred to MariaDB, instead of just dying a relatively quick death.
Why bother with MySQL if you can just migrate over to PostgreSQL? Yes, of course, some of the weirdest bits won't work, and errors will now (for a change!) actually interrupt your work instead of silently losing information. But it seemed like a good way to kill that ugly beast!
Are three very different things. Java in the server and in the client is alive and very very much healthy. Ugly and slow applets in the browser thankfully are almost dead — Because HTML5 delivered way better. But applets dying off does not in any way mean Java is any less healthy!
...And yes, after reading the link you sent: More than a cycling proselytizer (which I am), I am a safe cycling proselytizer. Using the road as regular traffic, not running over red lights, not riding on sidewalks, not riding to close to parked cars, not riding against the lane's direction, and a very large etcetera. Wearing a helmet by itself, I agree with bicyclesafe, will not help much if I am a daredevil. But being cautious and wearing a helmet is much better.
Thanks for the not needed course on logic fallacies. I know why I had the accident: Because I was a newbie (as I said, this happened several years ago), and I didn't account for the sight block that a street sign imposed on a car driver. She didn't expect me. Thankfully, she was just starting to move, and the accident was a very minor one.
I know the helmet saved my face — Not with 100% certainty, but quite probably. I also know my then-girlfriend had a much, much smaller accident while not wearing a helmet (she fell by herself at roughly half the speed I was going, because of irregular pavement), and did scratch her head. No, no permanent scars, but a nasty bruise and some scratches that took some weeks to properly heal.
I am active in many local cyclist groups. I know many people who don't wear a helmet out of choice, but I don't know anybody who says an accident's outcome was better because they weren't wearing one.
As I said in my post, I think that were I not to have my helmet on, I'd have a nasty scar, the product of using my forehead as a brake. It was a fairly low speed hit, but my head did hit the pavement *in* the helmet. So, the helmet absorbed some of the impact — but it also put a good 2cm between my skin and the street.
Also, a helmet is coated in plastic to make it smooth, almost derrapant. It would not be impossible for my head, with a far higher friction, to get stuck while reducing the speed of my body - and could end up in spinal damage, maybe fatal.
Of course, I have no way to know if that would happen were I not wearing a helmet. But I won't take chances.
