content: So this has been bothering me for quite some time now, but there appears to be some sort of update "lag" of the homepage whenever a new video is posted. The Episodes List seems to be consistently up-to-date whereas the homepage won't update until the next day or so...maybe longer, but I haven't exactly been counting.The first pic below is of the Homepage; notice episode #220 is on top.The second pic is of the Episodes List with the latest episode #221.Is the homepage setup to update based on some sort of scheme where Australia time is global or something like that? Australia is 16 hours ahead of EST so it's a blind guess. Or does Dave simply not update the homepage as often? I don't know how many times it's been like, "WTF?! When did Dave post a new video??" during social BS hour in the lab. =\

content: Quote from: slateraptor on November 27, 2011, 09:40:35 pmCorrect. I'm just a slack-arse.Actually, there is a technical reason for that.I have to upload to Youtube first because I need the embedded tag for the site, so I can't get that until it's uploaded and processed.I could hide it private first and then wait and then update both youtube and the site at once, but Youtube has bugs that has prevented that in the past. I could also time schedule updates on both sites, but that's just too much trouble. And in both cases, everyone would get the video later than they currently do. At least now, people watching Youtube or the Episodes page (autogenerated) get the video firstI usually finish my renders at night, so I like to simply leave the video uploading to Youtube and go to bed, and then read the comments in the morning.Dave.

The inherent problem with deciphering disassembled code... - Page 1

content: ...is that the disassembler is often incapable of determining whether binary data is executable or raw. It simply parses assuming the former, flags invalid op codes when it encounters raw vector data, convolutes and snowballs everything afterwards, and dooms you to scratching your head for hours on end trying to figure WTF went wrong with the script you wrote to extract a subset of the binary data being analyzed when it works perfectly.I feel like I've encountered my first real-world exemplification of the halting problem.P.S. A simple heuristic that eliminates deterministic branches would make life so much easier. I just might have given myself a computer science side project.

timestamp: November 26, 2011, 07:34:17 pm
content: For architectures where opcodes don't have a fixed length, alignment is also an issue. If you start decoding somewhere in the middle of an instruction, everything from that point on will be garbage. This is why good disassemblers like IDA allow you to mark the start/end of code or data blocks. Starting at a known entry point and working your way through the jumps is one way to deal with it.

My youngest granddaughter has requested a mobile phone and an mp3 player. Asked why and she said ' To phone Santa ' (Visions of credit card going into melt down) And the mp3 player?Its got a nice box! But in all seriousness would kids of today be happy with a model car or a doll? I think not. I love Christmas but each year it takes longer and longer to work out how to get the bloody presents to work! Sometimes I have to ask the kids to show me.... am I getting too old.

content: C8 in upper right. Brown body with yellow tip. On the other side is printed "22"...no dot or anything..just "22". Doesn't seem to conform to official color codes. Tempting to think it's 22uF, but the lower limits of my ESR meter is 1uF and it will not read this one. (and it's a confirmed good cap) FWIW this is on the power supply board of a 1980's vintage German machine CRT monitor.

content: Carbon tetrachloride, or "carbon tet" was a favorite degreaser in the old days, but it has been banned these days as it causes cancer.There are other degreasing solvents you can use instead, but if the black stuff on the cleaning brush is not grease those solvents will not help. Instead of solvents try an acid like limescale and rust remover. When you clean a metal surface with an abrasive the black residue is metal particles and oxides, which acids are good at dissolving.
