Not having used Twitter but having used Facebook, I want to know: When are they going to implement sorting by what my brain perceives as chronology? (For me personally, it is something like similarity to the present state rather than having anything at all to do with physical yesterday can seem much longer ago than some event 5 or 10 years ago if the latter is more "relevant" at the moment, & then switch around when I think of something else.)

Comment Re:Cluster Headaches????? (Score 1) 446

I am not a medical doctor of any sort, but that sounds almost like phenol intolerance. Has he ever tried either taking a bath with epsom salt or eating some egg yolk when he gets a headache? (Both act via sulfur compounds, which can counteract the effect of phenol intolerance, or at least helped for someone I know who gets headaches from similar sorts of things. Much moreso the salt bath, but egg yolk might be worth testing as it would be more portable...just make sure it is just yolk, since the white has the opposite effect (makes it worse).)

Comment Re:I just do some Python (Score 1) 497

When I was TAing, I had a pair of students submit very similar code, one in C & the other in C++, with printf vs. cout, swapping for & while loops, etc. But the overall control & data flow was identical. When questioned they insisted that the code was obviously not copied since it was not even written in the same language, & I tried to explain the concept of functional organization as separate from the exact text of the code, to no avail.

(Not nearly as comical as the people who submitted screenshots that included microsecond-precision timestamps & screen glare (but slightly different cropping)...)

Comment Re:Hole Punch - Double Sided Floppy (Score 1) 251

I once fixed a floppy that someone gave to me because it had bad sectors by sticking it under a CRT & degaussing it. Once formatted it worked great thereafter.

Speaking of CRTs, I had a magnet on a stick that looked sort of like a pen (although it was retractable & meant for retrieving things)...color Magna Doodle, degauss to erase.

Comment Color on a B&W screen (Score 1) 251

I made a TI-86 (& later a TI-92+) display multiple colors despite having a black & white LCD (picture here of the TI-86). I was sitting in an airport in Alaska trying to program it to do grayscale (by switching between black & white fast enough...many have done that before), but since I did not know how to program interrupts on the Z80 at that point, I just used a delay loop. I found that, for certain values of delay (depends on the remaining battery charge), it produced flashing red & green instead of black & white. More fiddling later showed that it is apparently caused by writing to the framebuffer at 100 Hz (whereas the screen refresh rate is quoted as 50 Hz), & that it was possible to get it to stop switching red & green around between flashes, but apparently not to remove the flashing effect entirely. This is probably because it has to build up stress (like when you poke a bare LCD & it makes that rainbow effect), & then it bleeds out & must be replenished periodically (although I might just have the timing slightly off, even though I switched to interrupt-based timing).

So I was not the only one to do that repeated-string-mapping method of compilation (although I did mine in high school (using C for bootstrapping, rather than QBASIC, IIRC)...earlier I was too busy playing with Visual Basic, which had its own compiler)...interesting.

I never tried to make my compiler optimizing, despite having a plan in my head to do so, because the binary for the compiler itself already fit in 64KB that a .COM file required, & I never did anything interesting enough with it for time to be an issue...& then other projects called.

Comment Re: I wonder (Score 1) 206

Suppose someone wants to take some blob of data from one location to another without having to upload & later download it (say, the connection at one or both ends is significantly slower than the flash storage on their phone, or the data is sensitive (but no so sensitive that it warrants a dedicated storage device...perhaps this case is rather unlikely)). They are not going to use it on the phone, so no need for a viewer, but they still want a way to transfer it (without having to find & keep track of a memory card, since they are already carrying their phone).

Well, I suppose one answer is to convince the device it is some supported file type & then fix that at the other end. But that seems silly.
