Checking the RingPlus site, the "free" plans seem to be $0/month for service + $X per unit of usage. One of their plans, for example, is $9 for (250 minutes voice + 250MB data + 250 sms + 250 mms). There is also an overage c

If you have never wired a house for electrical, then sure, the units seem arbitrary. But if you do, then the units seem very comfortable. 12ga for most typical 20a circuits, 14ga for light, 10ga or thicker for some heavy-duty circuits. Hey

It makes sense to me, based on my own limited personal experience as a college prof (teaching CS). Particularly for our intro classes, it's fairly common for a male student to struggle all semester and scrape by with a D-, then without

Alternative if you present regularly: 1. Enable "extended destkop", rather than "mirror desktop". 2. Select an appropriate wallpaper, or just black.

Speed of light within a fiber optic cable is about c/1.5, so closer to a factor of 3. Throw in various continents that need to avoided, I'd guess it would be closer to factor of 2 in practice.

You mean like vim, emacs, nano, kate, notepad, notepad++, wordpad, or any other plain text editor? Really - I don't get this impulse at all. From my perspective, the entire point of markdown (and RST I assume, though I haven't use

No, it's not a mistake. Each process has it's own virtual address space, but part of that space is typically used to map operating system code and data. The reserved part is anywhere from a quarter to a half on a 4GB 32-bit system

I don't understand. The usual explanation I hear (and that I think of) when explaining what a STD of x is, fall somewhere along the lines of "most (about 2/3rds) of the data will be within +/- x of the average". Is

Yes, perhaps I was being a bit unfair. However, bad teachers will always be with us, and won't start teaching the magic of computers just because you give them a c64 or basic. They'll just make kids write endless employee pay calc

Have you programmed in scratch for any significant amount of time? I have, so have my kids, and as a CS prof (at a small non-engineering college) I encourage my students to do so too. Before age 10, almost entirely on their own, my kids dis

Well, maybe? If the purpose re-keying is to recover from a transient compromise, then a single bit isn't really sufficient, is it? If the attacker has completely recovered the old seed, they can recover the entire rng stream up to the

Sigh. This is incorrect. Pi does not give the "nothing up my sleveve" property, because if I have a desired bit sequence in mind, I can find it in Pi, then retroactively claim that because it comes from Pi it wasn't "up

Why would you do that? Did you also try to explain the beauty of diffie hellman key exchange and the details of TCP selective acknowledgement before helping your client get an EV cert?

The actual quote was: “A lot of times, you actually look at these numbers, when you break a record, you break it by a few hundredths of a degree," So it's not clear if only record-setting years have small variation, or whether yea

Well, I looked at it and bookmarked it for possible use in my upcoming semester when we cover virtual memory. I'll have to go through it in a bit more detail and don't have the time now. But if you want feedback, my only comment a

I'm not sure what scale you mean. The demo I saw involved 100+ students in a crowded low-income rural Indian classroom with one teacher. The qrcodes were printed on regular paper on an inkjet printer. The image recognition software ran

Sorry about the missing reference. I was thinking of (a) classroom clickers, (b) poll everywhere, which as you point out is limited to polls, and (c) UW CP's student feature, which allows more interactivity but requires students to ins

Visiting MSR/Bangalore I was shown a neat demo using very simple QRcode-like paper and image recognition. Basically, each student had a paper they could hold up. On the front was a simple QR-code (facing the prof and camera). On the ba

I have taught for years using UW's Classroom Presenter software, hacked up to be more responsive and usable with a tablet and pen. So I'm fully on board with the concept. But frankly, the execution seems lacking. The qrcode/s

Exactly. In every science department I have been in, being chair is not seen as a privilege, but as a burden. Attitudes mostly range from "hell no, I'll quit if you try to make me chair" to "okay, I'll do it, but on

Based on this photo [1], I'm guessing they use a system much like a cog railway. There would be a continuous ring of teeth along the tracks and a small motor on the platform with a few inch gear to engage the cog. Or vice versa. The co

Gads, the even got the title wrong. Should be "Disproportionately common professions by Name". Or, actually, all we can tell from the little on that page is that the title contradicts the subtitle. So maybe the subtle that should
