  1. I'll concede that's what it looks like, but that's not really what I meant. Perhaps a more accurate phrasing would be that for most of those students, the ICT lessons they're receiving will have minimal impact on their daily lives.

    The Sekyedumase region is very near where my lab was... it's a big (by local standards) city in the middle of a farming community. The crowning achievement in the area at the time was a 3-story building. The vast majority of employment is local commerce or farming. When I was there, the city of Ejura had just gotten Internet access, delivered via microwave from a tower on the hill nearby. Despite English being the official language since it was a colony, many school classes are still taught in Twi, and there is a widespread reluctance to do anything non-traditional, mostly because parents don't want their kids to do anything differently from what they did.

    That "good enough" culture has had some very interesting effects. Students consider school as completely optional, with 50% attendance being very high. Farming equipment is still usually pulled by oxen. Having a car is seen as an extravagance, like Americans view having a private plane. A shopkeeper having a calculator is high-end, and the really fancy stores even have a functional cash register!

    At the same time, there's the incredible advancement of the African continent. While the farmer's oxen are pulling the plow, he's carrying a smartphone, connected to a high-speed cellular network, at least as good as anything in America. Everyone, even the beggar outside the market, has a cell phone. The Internet cafe' doesn't even have a land line telephone... their connection is data-only. As a culture, they've skipped a generation of technology, because they're arriving late to the game, and get to jump in without having anything left behind from inferior implementations.

    I would predict that Ghana has a market for highly-integrated convenience devices far more than desktop workstations. That cash register will eventually be replaced by a standalone NFC POS terminal, completely managed from an office in Kumasi or Accra. For personal computing, I'd expect the majority will be tablets and other portable devices more compatible with the open-community lifestyle, where the notion of privacy is almost entirely foreign. Note that most folks don't have valuables, so most doors don't have locks, so most folks try not to keep valuables at home.

    In short, I expect that Ghana (and Africa at large) will see rapid adoption of technologies that don't follow the UI/UX paradigms that America has had since the 1970s. While America moves slowly toward IoT and tiny personal systems, Ghana will embrace the new technologies from the start, completely skipping the old. Yes, the students do have their whole lives ahead of them... but the lessons they learn today in an ICT class will be roughly as useful for them as New Math was for American students.

    I'm glad you asked! I actually am really glad you asked... I would much rather talk about the principles of explosives and how they behave (hopefully inspiring further injury-free education), than name particular compounds and say how much fun they can be (usually inspiring stupid mistakes).

    Essentially, what makes explosives dangerous is primarily that they release so much gas during their reaction that it can't expand into the atmosphere fast enough, creating a shock wave. That expansion is primarily limited by the speed of sound, so having more explosive material mostly just raises the pressure behind the shock wave. Raising the pressure, in turn, increases the rate of the explosion, both due to physical effects and adding compression heat.

    With just a small amount of (low) explosive at normal conditions, setting it on fire will usually just make it burn. Sometimes it will burn quickly, but it still isn't particularly dangerous. Once compression happens, either by confining the explosion into a bomb or by having enough material to cause compression behind the shock wave, each additional gram of explosive adds not just to the total power, but also amplifies the rest of the reaction.

    I built a computer lab in Ghana. One laptop is plenty.

    A single laptop is enough to make a huge improvement in the students' lives, through demonstrations and guided lessons. Despite the promises of the Ghanaian government, a lot of these kids won't actually be taking the ICT test, and a large percentage of those that do will not be using computers in their daily lives for the foreseeable future. Having a laptop demonstrating key concepts is a good first step towards the education they need if they're one of the lucky few.

    A lab is stuck in one location. It's a prime target for theft. In time, it will be neglected, repurposed, and broken. A laptop is portable. It can be secured in a cabinet, carried discreetly in a bag, and taken to a repair shop (there's was a nice one in Kumasi a few years ago) frequently. The logistics of handling a single laptop are far easier to manage than a classroom full of them, and far easier than desktops.

    It's disappointing that this is currently scored 0. This is the right answer for this scenario.

    With strong Net Neutrality laws, there are limits to how sophisticated ISP throttling can be and still pretend to be legitimate. With that essentially eliminated now, the only meaningful test is to use actual traffic. Netflix has preempted this need for their own services by creating fast.com to look identical, going to Netflix servers over the same ports and protocols as normal Netflix traffic. It will be subject to the same throttling, and thus allows you to measure the speed you get when working with Netflix.

    I'd love to see other services hosting similar tools, but for now Netflix is the only major company I know of offering their own user-accessible performance test.

    On principle, I will not name a compound to anyone in context where it might be an inspiration to do things unsafely. If you want names of such things, even easily-found things, find a local chemistry or pyrotechnics group, and start setting up safe environments under appropriate supervision, who have the awareness and experience to intervene before you start creating excessive paperwork.

    It is entirely possible to produce explosive compounds recreationally, without making them into anything that could be considered a bomb. The best candidate I know of is a highly-unstable compound that used to be often used in basic chemistry classes. Immediately after production, it is a wet paste, and can easily be spread in a very thin layer, preferably no more than a few grams covering a 2cm radius circle. Once it dries, that circle will make a lovely pop if disturbed, making it great fun to put on desk surfaces.

    Of course, people are dumb. This particular compound grows in destruction exponentially as its quantity increases. A few grams is fun. A few dozen grams is dangerous. A few hundred is lethal. A kilogram in one location is probably a good reason to evacuate the building.

    I am part of a group that, among many other things, handles explosives for educational purposes, partly to help chemists who are not "bomb makers" get an intuitive understanding for just how much of an explosive substance is actually safe, and how to treat them with respect. Sure, we do also build bombs, but they're also detonated safely and in a controlled environment, in full compliance with applicable laws.

  12. Re:Once known as ClearChannel. on Largest US Radio Company iHeartMedia Files For Bankruptcy (reuters.com) · · Score: 1

    My station tried that for a while. We found that most podcast producers actually fall into three major categories:

    First, there are the planning-limited amateurs. By far the largest group, these are the folks who buy a microphone and start talking. They product a dozen segments of precisely one hour... or maybe 43 minutes... or maybe 67 minutes. They don't leave slots for commercial breaks or other station announcements, they don't follow a consistent format, and they don't have a long-term sustainable plan for content. Once that plan runs out, the podcasts stop, often with no warning to the broadcaster.

    There are also the quality-limited amateurs, who produce well-planned podcasts and have a chance of delivering great content... but it's not suitable for use. These folks think that a bedroom makes a great recording studio, or that walking down the street and talking provides a casual ambiance, and they generally have never heard of noise removal or normalization. Some of these could be good if they were properly adjusted, but that requires a lot of quality time with a good audio engineer, and that isn't often cheap.

    Finally, there are the professionals. These folks have been radio personalities for decades, been in every role in the station, and now see radio production as a way of life. They do everything right, and they know it. Unfortunately, though, these are also the folks who see radio as a moneymaker. They know that they have quality material, and they know that they can charge for it, so they'll charge for a radio station to play their content. It's typically cheaper than music to fill a time slot, but it still cuts into the station budget. A good number of these professionals also think they're good enough to demand particular time slots, or expect the station to promote them as more than just a way to fill time.

    It ended up being cheaper and simpler to run a regular studio, bring in local personalities, and have an in-house production team. They made enough content to fill peaks, and we had a few licensed shows from other studios to round out the main listening hours. An automatic DJ filled the rest of the time with music, commercials, and station announcements.

    Unfortunately, those locally-run stations usually can't afford to survive on their own. That's why they mostly joined the big conglomerates in the first place.

    I've worked at a local radio station. It's not a cheap business. Beyond the equipment costs, there are licensing fees that are essentially mandatory to keep content on the air. Even for talk radio, people want to be paid for their time. If you're going to avoid licensing by producing your own content, you need a studio, with facility expenses. Then, of course, you have all of the overhead of handling the technology involved, which today involves a significant IT budget, as well as the usual communications link to the transmitters, transmitter space rental, and so on...

    My station was pretty much just the hobby of a few wealthy listeners. Some folks dump money into a boat-shaped hole in the lake, but these folks likes to burn their cash at the top of an antenna tower. Our advertising income barely covered the electricity costs.

They also handle information logistics, with huge server farms and highly-scalable systems to handle their own information needs... and they just happen to sell off their capacity and capabilities, as well.

    For a while, I worked in a financial management office. For what you describe, the best tool I've ever seen was a plain spreadsheet in capable hands.

    Every expense gets broken down, and per-unit costs (like price per gallon of water) are filled out in one section. Every adjustable parameter (like number of toilets) goes in another section, and all of the system rules (like number of gallons/minute wasted) go in a third section. Finally, all of the results go in the last section, accompanied by all of the charts and projections.

    When presenting, the first two sections are discussed first, and the client (or HOA board) gets to put in whatever numbers they think are realistic. Then you switch to the end, and they see the computed cost of everything, exactly as their own numbers work out. That shows in plain view how their money is spent, confronting their assumptions. After that, you can go back and show hypothetical fixes (like lowering the number of leaky toilets), and show the changes in outcome. It tends to be very convincing to see almost all of their own numbers driving the output.
