Ask Slashdot: Professionally Packaged Tools For Teaching Kids To Program?

kubajz Problems not tools (107 comments)

As a matter of fact, in my experience you can use any of the recommended tools. However, my more pressing question is what PROBLEMS the kids should try to solve since this is tje best way to learn. Of course you can start with a simple game but soon you get into object cloning. You can do pong but you get into general angle reflections. You do anything geometric and get into sine functions. Does anyone know of a nice set of problems to solve, with increasing complexity, for young programmers?

Statisticians Uncover What Makes For a Stable Marriage

kubajz Re:Or, just don't get married. (447 comments)

Perhaps surprisingly, the "one parent at home" is fairly a recent invention, since the one parent left home to go work in a factory. For many centuries prior to that, most people worked close to home or at home, and typically the whole family was involved, whether it was agriculture or a trade. That meant that for example men spent more time with the rest of the family in "traditional" setups than many of them do now :)

Fixing Steam's User Rating Charts

As a matter of fact, does anyone know why Steam does not prominently feature Metacritic ratings anymore? Those really helped me choose games that I wanted...

How Tech Is Transforming Teaching In a South African Township

kubajz How do they do it? (26 comments)

Some really interesting ideas here, if you're lazy to RTFA:

One of the primary goals is to foster curiosity in the kids (which is essentially internal motivation, one of the strongest forms).

The kids often work in groups on tasks that are slightly above their current skill level, which teaches them cooperation and problem-solving.

Teachers mainly come in to fill in gaps by answering questions and summarize what the kids learn.

Then the kids spend time on Khan Academy or similar doing tests to make sure they mastered the subject.

It would be interesting to see which of the elements actually helps the most - I would say it's not the "PeerMarker" software that lets pupils compare two essays and show which one is better using a slider (no written feedback on students' written assignment? that must hurt the learning, although it's understandable given the lack of teachers), but a breakdown of the other elements would be very interesting. Too bad a lot of the article focuses on math, it would be interesting to see more detail e.g. about writing.

Ask Slashdot: Where's the Most Unusual Place You've Written a Program From?

kubajz Ski trip (310 comments)

When I learned programming my Dad took us to a skiing trip in the Slovak mountains - small cottage in the woods with a simple wood stove, nearest shop was 30 minute walk through the hills in deep snow, and whole days were spent skiing. The nights, however, we spent programming - with a pencil and an eraser ("the most important tool of a good programmer", my Dad said), and he was my compiler, debugger and processor, executing my handwritten programs for me and pointing out mistakes :)

Glenn Greenwald: How the NSA Tampers With US Made Internet Routers

kubajz Re:Fuck the foreigners Re:What about inbound? (347 comments)

Interesting thought, that we would have these rights if there was no Absolute Law or something similar. What would lead us to conclude that everyone has the right to Liberty, for example? Is it a matter of taking a vote about it? And if the majority vote against, could they then imprison the minority? I live in Europe and one thing I envy the US Constitution is the way rights are defined - that they are given by an Absolute and therefore cannot be voted away :)

Kids To Get the Best CS Teachers $15/Hr Can Buy

Please mod parent up. I know this is Slashdot but seriously... where does the idea that teaching is "basic" come from? And how come someone who has reviewed appropriate literature and proven the GP most likely wrong is not modded higher already?

Stanford Bioengineers Develop 'Neurocore' Chips 9,000 Times Faster Than a PC

kubajz Re:Still a long way from brain-boxes (209 comments)

> Meanwhile we need to ask ourselves - if we're creating this simulation based on the human brain, then what are the odds that some form of consciousness dwells within it?

If there's a consciousness in the simulation, then consciousness is just a result of a deterministic calculation, isn't it? In that case, what's the point of "asking ourselves"? Our consciousness would also be just a deterministic process so we can ask all we want but the answers we will arrive at are already given and we could not change them no matter how hard we "tried to think it through"... yawn :)

Kim Dotcom Just Launched His New Music Service With His Own Album

kubajz Re:MEGA Windows sync client (69 comments)

My understanding is that MEGA work by encrypting your data client-side within the browser, so the only thing that could happen to the said shopping list is getting lost, but until it is sent back to your browser and decrypted there even Dotcom cannot read it - that's the main reason why they cannot provide you with a password reset feature. They have a bug bounty program for finding holes in this setup. I do not trust the guy either but I think that this kind of arrangement, while having a side effect of protecting him from liability for users' content, also helps keep my data more secure. OTOH I know Slashdot is full of people more knowledgeable with the matter, so I do not mind hearing more from someone who can poke a few holes in their model :)

kubajz MEGA Windows sync client (69 comments)

I hope this is not too off-topic, but Mega has recently (and very quietly, without even a mention on their blog) released a Windows sync client - a significant step in being feature-complete compared to their less-encrypted competition of Dropbox, Google Drive or Microsoft SkyDrive.

A Rebuttal To Charles Stross About Bitcoin

kubajz Re:The problem is many BTCtards love deflation (396 comments)

I think Stross' article has many weak arguments, and one strong one - deflation. Thank you for explaining why it's important. As a side note, however - perhaps there was no need to call other human beings "BTCtards".

Ars Checks Out CyanogenMod's New Installer

kubajz Re:FOR-PROFIT CORP !! NO THANX !! (143 comments)

If profit is not necessary, could you give me one reason why anyone would fund a startup? Could you explain how to build a factory if the bank won't give you a loan? How to expand internationally once you've invested all your personal wealth into your business? Why would someone risk being a business owner and not an employee? See, all these are things that are typically solved by equity investment, or (partly) giving up your ownership, and these investors, for the large risk they are taking, expect a return - profit. Interestingly, as an example, in Islamic finance it is okay to turn profit but it's forbidden to give loans and ask for interest which is understood as making money without taking a risk. Or, in other words - the business generates value for customers (otherwise they would not buy its products), for employees (who get wages), for loan providers (because you pay interest on your loans) and finally for owners who are running the largest risk - a risk that there won't be anything left to pay for their investment in the company. You would suggest to let them take losses but not have the option of getting profits... and I think it would not work :)

Has Flow-Based Programming's Time Arrived?

kubajz Spreadsheets (268 comments)

Spreadsheet software such as Excel or Calc are very good examples of flow-based programming, and it seems non-programmers can cope with it. However, we all know how hard it is to get larger-scale projects in Excel to work :)

Crowdfunded Bounty For Hacking iPhone 5S Fingerprint Authentication

kubajz Why lock a phone? (148 comments)

Assuming that you protect your phone from the random thief, I would recommend installing a tracing app and leaving the phone unlocked - a locked phone will just encourage the thief to hard reset it or turn it off immediately. Same with a laptop - I had some tracing software installed but unfortunately I forgot to enable the guest account so the thief could not use the laptop... and therefore never gave me a chance to locate it.

Games for basic learning?

kubajz kubajz writes  |  more than 3 years ago

kubajz (964091) writes "My kids (grades 2 & 4) need to spend a lot of time practicing basic math, touch-typing and English as a second language (and Czech, but I don't expect Slashdot help here).
They also love to play computer games. I generally dislike cheap "edutainment software", but there are some cool games I stumbled upon — like The Typing of the Dead for touch-typing, Bidmas Blaster for math or JoyTunes for playing the recorder.
My preference is Windows and free or cheap, but others might be interested in other OSes and more expensive options. Feel free to include any modern-day "SimCity"s, but please refrain from anything equally or more serious than the Khan Academy.
So, what bits of software do fellow Slashdotters use for areas like their offspring's math practice?"

Unattended presentation from a number of sources?

kubajz kubajz writes  |  more than 6 years ago

Kuba (Prague, CZ) writes "OPEN DOOR; N

You walk through the glass door to the lobby. You see a reception desk with a secretary, a sofa with a slashdotter, and a huge LCD screen with some presentation.


You sink your bottom into the soft leather of the sofa next to the slashdotter. SYNTAX ERROR NEAR 'LCD'


You look at the silent LCD screen. It is split into several sections. One of them is a video of recent news; you're not able to tell whether it's an RSS video feed or a live TV channel. Another section of the screen seems to by cycling through a playlist consisting of short clips about the company and various Powerpoint slides. The top left corner has some static text followed by current time, and a text of an RSS feed is scrolling across the bottom, telling people about the events happening at the company today.

ASK SLASHDOTTER "how did they create such a nice presentation for the LCD screen?"

You ask: "How to create an unattended presentation similar to this one, ideally using free or open source software, either in a browser or in-" and you stop there because you are afraid to say "Windows" while sitting in the same sofa as the slashdotter."
