Utah

Powder Mountain run panormaa

I had a Utah ski trip on the books before the mcl thing happened. I decided to go anyway and made an eleventh hour decision to bring skis even if I wasn't fit to use them.

Powder Mountain lodge panorama

I spent the beginning of Friday working in the Powder Mountain lodge. It was pleasant, but I decided to risk a half day on the slopes. It went pretty well, although new snow didn't arrive until Monday. I left on Sunday. But I did get to sample the local brews and have a spontaneous League of Sport mini golf event.

Hard drive

So I always knew that Seagate sucked. I heard stories back at an old job. Ted said so and he deals with this stuff. Why did I end up with a Seagate drive? I think it was the farfetched hope that when they bought Maxtor, their desktop department would be more Maxtor than Seagate. This was naive.

Photography portraiture subject and assistant

My data drive (os is on ssd, of course) decided to stop working seconds to minutes after every bootup. Of course this all began just after uploading photos from a birthday session. I looked around the internets and didn't find good things:

The .11 line is notorious for this problem, especially the 1.5TB version.

The only HDDs I've had ever problems with were Seagate drives, and both were .11 drives. My issue was different - very high error counts which caused very poor performance from sector reallocation. That whole line was very problematic.

Source.

Turns out this was common enough to provoke an offer for free data recovery. Wish I had known about it when the drive was still under warranty. Would they honor it still? Doubtful. I expected them to go full ASUS. On the other hand, this appeared to be a design defect, not manufacturing.

I called customer service. Not open on weekends. Does this mean it's not outsourced? Weird. Oh well, I took matters into my own hands.

I appeared to have a brief window from which to extract files after each bootup. No way was I going to do this thing manually. Not only would all the clicking take forever, but Windows file copy isn't exactly quick. So it was time to throw together a little app.

Since my stuff was pretty well organized, there were a few well known locations I needed to save, e.g. photos/2016/*. Meaning I could plug in a few super-directories and let it do its thing - for the few moments before the drive barfed. Then reboot and repeat.

So the code had to keep progress and be ready for file access errors.

			if (source.exists()) {

						files.add(file);

						files.add(random.nextInt(files.size()), file);
					}
				}
				
				// Walk the randomized file list.
				for (File file : files) {
					File target = new File(destination, file.getName());
					// Don't try to go deep, just inform user of a subdirectory.
					if (file.isDirectory()) {
						log.append("Skipped subdirectory: " + 
							   file.getAbsolutePath() + "\n");
					}
					
					last_file = target;
					if (!target.exists()) {
						try {	
							count++;			
							Files.copy(Paths.get(file.getAbsolutePath()), 
								   Paths.get(target.getAbsolutePath()));
						}
						catch (Exception e) {
							log.append("Failed on " + 
								   last_file.getAbsolutePath() + 
								   "\n");
							fails++;
							if (fails > 7) {
								throw e;
							}
						}
					}
				}
				log.append("Finished " + source.getAbsolutePath() + " " + 
					   source.listFiles().length + " files\n");	
			}
			else {
				log.append("Could not find: " + source.getAbsolutePath());
			}
		}
		catch (Exception e) {
			log.append("Failed on " + last_file + " " + count + " completed\n");
			log.append(e.getMessage());
		}
		

		try {
			PrintWriter writer = new PrintWriter(
					new FileOutputStream(new File("C:\\data\\output.txt")));
			writer.write(log.toString());
			writer.close();
			System.exit(0);
		}
		catch (Exception e) {
			System.exit(1);
		}
	}
	
}
All's well that ends well. Running it took some time (on account of the reboots), but it gave me a chance to work on my Fire Emblem: Fates playthrough.
WTF SQL?

On the subject of code, but completely unrelated, say you have a sql table with a set of columns that collectively form a uniqueness constraint. Yeah, well, for a given row, if any of those columns is null suddenly the constraint doesn't matter. Like... why?

Ugh, sql.
Pool


The pool is now indoors-ish. The primary motivation was to prevent all the leaves and junk from going into the water. It may also keep the thing warmer and reduce evaporation of water and/or chlorine.

I've gotten a bit deeper into Helldivers, and even recruited Dave for some couch co-op.

I saw through an entire galactic war (community effort). We even overflowed the shot counter.

Yeah. The other one this time. Had to be an El Nino winter, too.

While sports and overnight camping were out, I figured I could still manage some 'froading (four wheels, anyway) and shootin' at the Cooley ranch.

Obviously I'm no good for Tuesday volleyball, but that doesn't mean I can't still hang out. I toted the d700 and annoyed everyone with the flash.


Okay so when they went down to five I was called up for stationary setter duties.
