An anonymous reader writes: I volunteer at a inner-city community after school program focused K-8th grade. Right now, due to the volunteer demographic, we spend most of our activity time in arts and crafts and homework. The 5th-8th students are getting restless with those activities. I've been asked to spice it up with some electrical wizardry. What I'd like to do is introduce the students to basic jobs skills through computers. My thoughts are that I could conduct some simple hands-on experiments with circuits, and maybe some bread boards. Ultimately, we're going to take apart a computer and put it back together. How successful this project is will dictate whether or not we will go into programming. However, whatever we do, I want the kids to obtain marketable skills. Anyone know of a curriculum I can follow? What experiences have you had with various educational computing projects?

Ask Slashdot: What Makes a Great Software Developer? 210

Nerval's Lobster writes: What does it take to become a great — or even just a good — software developer? According to developer Michael O. Church's posting on Quora (later posted on LifeHacker), it's a long list: great developers are unafraid to learn on the job, manage their careers aggressively, know the politics of software development (which he refers to as 'CS666'), avoid long days when feasible, and can tell fads from technologies that actually endure... and those are just a few of his points. Over at Salsita Software's corporate blog, meanwhile, CEO and founder Matthew Gertner boils it all down to a single point: experienced programmers and developers know when to slow down. What do you think separates the great developers from the not-so-fantastic ones?

An anonymous reader writes What would be the best media to store a backup of important files in a lockbox? Like a lot of people we have a lot of important information on our computers, and have a lot of files that we don't want backed up in the cloud, but want to preserve. Everything from our personally ripped media, family pictures, important documents, etc.. We are considering BluRay, HDD, and SSD but wanted to ask the Slashdot community what they would do. So, in 2015, what technology (or technologies!) would you employ to best ensure your data's long-term survival? Where would you put that lockbox?

Ask Slashdot: Is Pascal Underrated? 488

Posted by timothy
from the let's-make-a-wager dept.
An anonymous reader writes In the recent Slashdot discussion on the D programming language, I was surprised to see criticisms of Pascal that were based on old information and outdated implementations. While I'm sure that, for example, Brian Kernighan's criticisms of Pascal were valid in 1981, things have moved on since then. Current Object Pascal largely addresses Kernighan's critique and also includes language features such as anonymous methods, reflection and attributes, class helpers, generics and more (see also Marco Cantu's recent Object Pascal presentation). Cross-platform development is fairly straightforward with Pascal. Delphi targets Windows, OS X, iOS and Android. Free Pascal targets many operating systems and architectures and Lazarus provides a Delphi-like IDE for Free Pascal. So what do you think? Is Pascal underrated?

Ask Slashdot: Where Can You Get a Good 3-Button Mouse Today? 429

Posted by timothy
from the hiding-with-the-egg-cream dept.
guises writes Ever since mouse wheels were introduced the middle mouse button has been sidelined to an inadequate click-wheel function, or in some cases ditched altogether. This has never sat well with me, a proper middle button is invaluable for pasting, games, and navigation. More than that, my hand categorically rejects two button mice — the dangling ring finger causes me genuine physical discomfort. I have begged Logitech on multiple occasions to make just one, among their many screwy specialty mice, to replace the Mouseman which I loved so dearly. I thought for a moment that I had been answered with the g600, only to find that they had put the right mouse button in the middle.

So my question to Slashdot is: where does a person turn for a three button mouse these days? I've only found two, both ergonomic and priced accordingly. I use the Contour and like the shape and wheel position, but would love to find something wireless and with a higher DPI sensor.

Ask Slashdot: Best Anti-Virus Software In 2015? Free Or Paid? 467

CryoKeen writes: I got a new laptop recently after trading in my old laptop for store credit. While I was waiting to check out, the sales guy just handed me some random antivirus software (Trend Micro) that was included with the purchase. I don't think he or I realized at the time that the CD/DVD he gave me would not work because my new laptop does not have a CD/DVD player.

Anyway, it got me wondering whether I should use it or not. Would I be better off downloading something like Avast or Malwarebytes? Is there one piece of antivirus software that's significantly better than the others? Are any of the paid options worthwhile, or should I just stick to the free versions? What security software would you recommend in addition to anti-virus?

Ask Slashdot: Has the Time Passed For Coding Website from Scratch? 302

First time accepted submitter thomawack writes As a designer I always do webdesign from scratch and put them into CMSMS. Frameworks are too complicated to work into, their code is usually bloated and adaptable online solutions are/were limited in options. I know my way around html/css, but I am not a programmer. My problem is, always starting from scratch has become too expensive for most customers. I see more and more online adaptive solutions that seem to be more flexible, but I am a bit overwhelmed because there are so many solutions around. Is there something you can recommend?

Ask Slashdot: Can I Trust Android Rooting Tools? 186

from the spider-sense dept.
Qbertino writes After a long period of evaluation and weighing cons and pros I've gotten myself a brand new Android tablet (10" Lenovo Yoga 2, Android Version) destined to be my prime mobile computing device in the future. As any respectable freedom-loving geek/computer-expert I want to root it to be able to install API spoofing libraries and security tools to give me owners power over the machine and prevent services like Google and others spying on me, my files, photos, calendar and contacts. I also want to install an ad-blocking proxy (desperately needed — I forgot how much the normal web sucks!). I've searched for some rooting advice and tools, and so far have only stumbled on shady looking sites that offer various Windows-based rooting kits for android devices.

What's the gist on all this? How much of this stuff is potential malware? What are your experiences? Can I usually trust rooting strategies to be malware-free? Is there a rule-of-thumb for this? Is there perhaps a more generic way for a FOSS/Linux expert who isn't afraid of the CLI to root any Android 4.4 (Kitkat) device? Advice and own experiences, please.

Ask Slashdot: Migrating a Router From Linux To *BSD? 403

from the hiring-a-new-traffic-cop dept.
An anonymous reader writes I'm in the camp that doesn't trust systemd. You can discuss the technical merits of all init solutions all you want, but if I wanted to run Windows NT I'd run Windows NT, not Linux. So I've decided to migrate my homebrew router/firewall/samba server to one of the BSDs. Question one is: which BSD? Question two: where's some good documentation regarding setting up a home router/firewall on your favorite BSD?
It's fine if the documentation is highly technical, I've written linux kernel drivers before :)

New submitter msubieta writes I have been developing some applications to use in small businesses using Windows and SQL Server. I would like to move on and start doing the same thing in Linux. I have looked at several Frameworks/Databases/Development environments and I really don't know what is the best/simplest/fastest to learn approach. I use VS and C# mostly, although I could easily go back to C++. I found Qt and GTK+ are the most common frameworks, but they seem to lack controls that deal with datasets and stuff (sorry, spoiled by the .net form controls), but I also know that I could use Mono in order to make the jump. I would have no problem on moving to MySQL, as I have done quite a lot of work on that side, and I would like to stick with the traditional client server application, as I find it easier to maintain, and a whole lot more robust when it comes to user interaction (web apps for POS applications don't seem to be the right way to go in my view). Any suggestions/comments/recommendations?

Within 10 seconds he had it playing on his laptop, but he didn't really get the joke because he had never seen a typewriter, nor heard the characteristics sounds — the clack of the keys, the end-of-line bell, the zip of the carriage return — that the typewriter makes. What other sounds do we not hear any more? More points for the longer they lasted (typewriters were around for over a century).

Ask Slashdot: Options For Cheap Home Automation? 189

Posted by timothy
from the fan-blows-out-the-candles dept.
New submitter goose-incarnated writes I'm looking at cheap and simple home automation. Unfortunately I'm not too clued up on what my options are. There are such a wide array of choices, none of which seem (to me) to be either cheap or simple. I'd like to: Turn switches on/off (lights, wall sockets, general relays, etc); Read the status of on/off switches; Read analog samples (for example, temperature sensors); 'Program' switches based on analog samples/existing switches (for example, program a relay to come on at 30C and go off at 25C, thereby controlling the temperature); Similarly, program switches to go on/off at certain times; Record the samples of analog or digital inputs for a given time . I'd like to do the above using smartphone+bluetooth (for when I'm in the vicinity of the room), or smartdevice+WiFi (for when I'm in the house, somewhere), or even in a pinch, using HTTP to access a server at home from 600km away (which is what I'm willing to do). I'm definitely not willing to stream all my requests/data/responses through a third-party so third party cloud subscription solutions, even if free, are out of the question. Finally (because I know the Slashdot crowd likes a challenge :-)), I'd like something that is easily reprogrammable without having to compile code, then reflash a device, etc. What languages for embedded devices exist for home automation programming, if any. A quick google search reveals nothing specially made for end-users to reprogram their devices, but, like I said above, I'm clueless about options.

Ask Slashdot: High-Performance Laptop That Doesn't Overheat? 325

Posted by Soulskill
from the chestnut-roasters dept.
AqD writes: Last year we started to replace business/multimedia-grade laptops with gaming laptops at work, after several years of frustration with overheating and throttling issues that plagued our laptops from Acer, ASUS, Dell, Lenovo, and basically every brand you can find on market, making it impossible to write code and run db/test environment all on the same laptop.

The first new batch comes from Clevo because their gaming laptops don't look like gaming laptops, and they offer 3-6 disk slots which we badly need. The result is acceptable, however, not quite as good as I had expected. Mine has i7-4700mq CPU which is more or less equivalent to an older i7 on the desktop, but its temperature is raised to 70-80C while turbo boost is on, even with the best thermal paste. My friend's i7-4801mq is worse — it could never stay at the advertised 3.6GHz for more than a few seconds before it burns up over 90 and starts to throttle. Its benchmark result is nearly identical to the 4700mq because of heat problems. And it's only 3.6GHz! The best i7 CPU on a desktop could easily run closer to 5GHz with 6 cores / 12 threads running!

So what should we choose next time? We're not looking for something cool or slim or light. We need real laptops which can at least run prime calculation at advertised turbo boost speed, full cores/threads for an entire day. A nice bonus would be manual fan control plus easy access to the fan for cleaning.

Steve Parrish writes: I needed a new laptop and found a great deal on an Asus Transformer TP500L. It's one of the laptops where you can flip the screen back and use it as a tablet. I'd like to replace Windows 8.1, and I'm having a difficult time finding a Linux distro that will work on it. I'm familiar with Mint, SolydX, and older Ubuntu versions. I tried the latest Ubuntu with Unity and didn't like it, but the OS installed with only a few minor issues. Has anyone tried any other distros on a hybrid laptop with a touchscreen? I've used Linux for several years, but I'm no guru -- I'm not comfortable with the command line or other advanced workings. Any suggestions would be appreciated.
