Firefox 31 Released

khellendros1984 Re:What version would be this (143 comments)

The version I'm running is numbered 29.0.1, which makes some sense (major.minor.patch). Do you mean "Is anyone keeping track of which versions break the API (maj), extend the API backward-compatibly (min), and fix bugs (pat)"? I don't think anyone is, in those terms.

How One School District Handled Rolling Out 20,000 iPads

khellendros1984 Re:We shall see. (255 comments)

I never memorized multiplication tables, and yet I can do such calculations quite easily.

Ah, so you count addition/subtraction on your fingers and do multiplication by iteration? Or do you mean that you didn't bother to learn the operations the way that school taught you and learned them piecemeal as you needed them? If it's the first case, I'd say that you're an idiot. If it's the second, well, to each their own, but I'd say that you still rote-memorized the tables, just in a less-structured way.

In general, I agree that rote memorization doesn't lead to education in a useful sense, but you're deluding yourself if you think that it's absolutely avoidable in all cases.

Favorite "Go!" Phrase?

RTGs are commonly used for interplanetary satellites. That was the first use that came to mind, for me.

How One School District Handled Rolling Out 20,000 iPads

khellendros1984 Re:We shall see. (255 comments)

If you expect not to be tied to a calculator for life, then there are some facts that need to be memorized. The three things that come immediately to mind: the addition/subtraction tables, multiplication/division tables, and the order of operations (i.e. PEMDAS). The concepts for each of those topics are simple, but I get daily use out of the tables that I rote-memorized in grade school.

Beyond that, I'd agree; generally, rote memorization is harmful, and when you get into real mathematics, those facts aren't as useful. I don't see math as the real reason that we teach arithmetic, though. It's useful to be at the grocery store and easily know how much you're going to be paying total if you're buying 4 items at $6.49 and 5 at $2.37. If you disagree about the purpose of memorizing those facts (for most people), or the usefulness (in daily life) of having memorized them, then I'm not going to try to convince you. Your replies sound like you're just trying to be contrary, anyhow.

How One School District Handled Rolling Out 20,000 iPads

khellendros1984 Re:Mission creep. (255 comments)

if you aren't on Android which does everything it can to keep you tethered to Google.

What are you talking about, specifically? On every Android device I own, connection to Google services is optional (if you're willing to flash the OS), and an internet connection is no more necessary to use the functions of the device than it is on iOS devices.

The "Rickmote Controller" Can Hijack Any Google Chromecast

khellendros1984 Re:Maybe it's just me ... (131 comments)

I suspect that the article and summary are inaccurate. There's a factory reset button on the Chromecast, and it from the description of the device, it's just de-authing the CC from the network it's connected to, configuring it to connect to the Pi, and sending a command to display a link. I've used that button to delete the config and set up the CC at a friend's house, and none of the text descriptions on this story make it sound like the Rickmote is doing anything else.

Comcast Customer Service Rep Just Won't Take No For an Answer

khellendros1984 Re:105 megabits per second (401 comments)

In tech we reach plateaus of 'good enough' for the time and resources involved.

And then someone comes up with some kind of outlier use case that exceeds the requirements of "good enough", and sometimes that use case becomes more and more common over time. "Good enough" is constantly redefined.

My most recent energy-saving bulbs last ...

khellendros1984 Re:2-year CFLs (278 comments)

I've got four in a ceiling fixture that were there when I bought the place 4 years ago. They take time to "warm up", but never flicker or buzz, that I can tell. They took the same amount of time back then as they do now, so my guess is that they were just early-ish models that were designed to look like incadescents. I've got two in nightstand lamps, which get power-cycled perhaps a half-dozen times a day, and have been going for 3-4 years so far. I've got a couple more in standing lamps that I don't remember when I installed, and one being used as a porch light that's just been there about 8 months.

I've had fairly good experiences with CFL bulbs, it's interesting to see how many people have had much more negative ones. I guess I've been lucky.

Visualizing Algorithms

khellendros1984 Re:Visualize (50 comments)

I identify with your school experiences, although maybe not in as extreme a way; I could generally muddle through rote memorization to a certain degree, but my retention was terrible. The understanding was left behind when the specifics faded away...

Anyhow, for me, the "picture" exists, but it's more tactile than visual. There are visual aspects, but it's not how I process most of the information. Loops are spinning wheels when they don't have a clear exit condition, and feel like unrolled spirals when they're "for" loops going over specific ranges. Algorithms seem like they have a size/weight, which corresponds to my idea of how quickly they'll run on a given set of data (although it's not always accurate, yet).

If I don't remember how a section of code works internally, it feels hollow, and when I read the code, it's like looking inside the black-box. If I change something outside the box, I feel the domino effect, and when it hits the box, I need to look inside to see what'll fall over. I can also feel like threading some string through the eye of a needle, when I'm running some value up through a class hierarchy, or something.

I think that the important insight is that a lot of us become very skilled at constructing mental models of what we're working with, and gain some sort of sensory perception (often vision-related) of how the model functions. I think it's telling that (in my case) the world falls away from my perception when I'm working through a complex problem, and closing my eyes sometimes helps, as well.

Ask Slashdot: Is It Feasible To Revive an Old Linux PC Setup?

khellendros1984 Re:Let's see... (176 comments)

OP specified old software, new hardware. Sticking a VM (and accompanying modern OS) as a compatibility layer between the two seems sensible, and not necessarily in contradiction of "the rules". OP also mentioned using ARM-based hardware to run their X86 software. My guess is that they're just throwing words at the wall to see what sticks, and that they'll be happy with whichever solution will let them run their older software.

Ask Slashdot: Is It Feasible To Revive an Old Linux PC Setup?

khellendros1984 Re:Shouldn't be a problem (176 comments)

It sounds like the end goal is to run their older software, though. That should be possible, provided library dependencies can be worked out (and emulation of any direct hardware access).

If the goal is to run a complete older system on new hardware, emulation in some form is the best bet. Running the old OS directly on modern hardware isn't likely to be feasible (without extensive modification to the old OS).

US Agency Aims To Regulate Map Aids In Vehicles

khellendros1984 Re:What The?!? (216 comments)

Except that CreatureComfort wasn't arguing what the money *should* be spent on, they were arguing that in the case that the most desirable things don't get funded, that at least we aren't funding the *least* desirable things. Essentially "the new status quo isn't bad enough that I can be assed to fight it". You're putting words in their mouth that are strikingly different than what it sounds like they intended.

New Permission System Could Make Android Much Less Secure

khellendros1984 Do not want. (249 comments)

I routinely deny apps their updates because I don't like their modified list of permissions. This sounds like it'll make it harder for me to use my phone the way that I want to (which is the reason that I decided against an iOS phone in the first place). Google, you're whittling down my reasons to stay with your devices (or at least with the stock OS).

Credit Card Breach At P.F. Chang's

khellendros1984 Re:Cash and checks (117 comments)

You fail to mention the full, tedious process for reporting fraudulent card transactions, and getting them reversed. Whenever I've had to do it (recently, almost yearly), There are records to review, paperwork to fax, etc. to confirm what charges are legit and which aren't.

With my card, in most cases, I get a call where they verify a half-dozen or so purchases. There was once where they called me to say that my card was cancelled, with a new one in the mail. I've never had to fill out any paperwork from that particular bank/card, let alone had to fax anything. The policies vary company-by-company, so something that's onerous for you may be much easier for someone else.

Comcast Converting 50,000 Houston Home Routers Into Public WiFi Hotspots

khellendros1984 Re:Monthly quota? (474 comments)

Well, that, or they'll track have the wifi access over a different VLAN, like similar schemes in other areas do. I can imagine someone that's about to go over their quota switching to the public hotspot's ssid to avoid charges, though. I'm not sure what comcast plans to do about that situation.

Lenovo to offer $200 budget tablet

khellendros1984 (792761) writes "Amazon's not the only big-name company planning on a budget-level tablet release; Lenovo recently announced their Ideapad A1 tablet as competition. It includes a 1GHz Cortex A8 CPU, along with other features more commonly seen on higher-priced tablets, such as dual cameras, bluetooth, GPS, wifi, and a MicroSD slot. Is this the start of the Android tablet price avalanche?"
