12:00 AM
(Amazon Glacier likely uses LTO-6)
@Bob, thanks for the advice and I'll be sure to look at other storage options as my needs evolve.
 
Bob
@bwDraco I actually wonder about your storage requirements.
You said photos?
 
Yup, as archives.
 
Bob
Even 5 TB is a lot of photos o.O
 
I have about 200 GB at this time.
 
Bob
Assuming 20 MB per RAW, that's a good 50k photos per TB
 
12:09 AM
Storage requirements had exploded due to the use of RAW+JPEG and my job as a sports photographer.
It's more like 50 MB per image (RAW+JPEG+select photos post-processed).
 
Bob
Hm.
 
Does the JPEG store the same or less data than the RAW? If so, I would just not store them if storage space was an issue
"Don't save what you can recalculate" -Raymond Chen
 
Bob
@BenN JPEG is usually ~ 10MB
 
I've been evaluating deleting the out-of-camera JPEG, keeping only the post-processed result.
 
Bob
@bwDraco What kind of post-processing?
If it's just the standard adjustments (lighting, etc.) on the RAW, those can be stored as pure metadata.
 
12:12 AM
@Bob The sidecar files containing the metadata are retained.
 
Bob
More involved editing would need a full raster export, yea.
 
However, the format used for the sidecar files is subject to change and may break in the far future.
 
Bob
:\
 
For images that are post-processed, I might throw out the out-of-camera JPEG. That will reduce redundancy.
 
Bob
@bwDraco Sounds to me like you should find a more stable format that doesn't require exporting as raster image...
 
12:15 AM
(they're RawTherapee .pp3 sidecars—RT has been a core part of my workflow for more than a year)
Digital asset management is such a pain in the butt but sadly, it's an unavoidable part of being a photographer.
I am evaluating throwing out the .dng RAW files for older images that are not expected to ever be post-processed.
 
Bob
@bwDraco I wonder if you can save any space by decompressing the RAWs and then compressing them all in a solid archive.
 
I'm not sure if I can modify the RAWs this way...
I can't find software to do this.
 
They are compressed DNG out of camera.
 
Bob
Not sure if you'd save enough to make it worth the trouble.
@bwDraco DNG Converter can convert to an uncompressed form.
 
12:23 AM
Hmm...
 
Bob
Which means it'll take more space in that intermediate stage, but solid compression should work better on the original uncompressed data than already-compressed data.
I'm not sure how much better, and if it's enough to make it worth the effort.
 
I'll give it a shot.
 
Bob
Of course it also assumes that DEFLATE/LMZA/etc. are just as efficient as whatever DNGs use for lossless compression.
@bwDraco Best if you can do a comparison by compressing the already-compressed DNGs then comparing to compressing the uncompressed DNGs.
 
I'm planning to do this, hold on...
 
Bob
Make sure you don't use ZIP. ZIP isn't solid.
7z would work.
 
12:25 AM
7z LZMA is my standard archive format.
 
Bob
tar + compression would also work
@bwDraco LZMA2?
 
No, just the old LZMA format.
Processing...
 
Bob
@bwDraco LZMA2 should be faster if you have the cores. LZMA is limited to two threads on 7-zip.
 
I'm aware of that.
I'll give it a shot.
 
Bob
And it's supposedly better on precompressed data, but that's not really relevant here. Dunno if it's worse for other types, or by how much.
 
12:30 AM
Hmm. I need to use the custom compatibility option to select uncompressed DNG output.
47 MB each file uncompressed.
53 images compressed in camera: 1.65 GB.
Uncompressed: 2.43 GB.
 
Bob
> The only instance where compression ratios could be worse is when threads of 4 or more are used because of the way LZMA2 handles the data-stream:
o.O
 
7z LZMA2 (32MB dictionary, 273 word size, solid): 1.5 GB (projected, compression in progress)
 
Bob
@bwDraco Apparently DNG uses lossless JPEG (1992, not 2000) for compression. So it might be better than LZMA, even taking into account solid.
@bwDraco Is that starting from the already compressed or the uncompressed files?
 
Uncompressed.
 
Bob
> the lossless coding process employs a simple predictive coding model called differential pulse code modulation (DPCM). This is a model in which predictions of the sample values are estimated from the neighboring samples that are already coded in the image. Most predictors take the average of the samples immediately above and to the left of the target sample. DPCM encodes the differences between the predicted samples instead of encoding each sample independently. The differences from one sample to the next are usually close to zero.
So DNG uses lossless JPEG, not JPEG-LS
 
12:39 AM
It looks like all of the metadata are retained.
 
Bob
> There is a special Lossless JPEG codec, but from what I've heard, it's mostly unsupported and its efficiency is somewhere around PNG's. I would be interested in reading some facts on that, though.
 
The final result is 1.45 GB.
 
Bob
@bwDraco So still better than DNG's lossless compression. But it doesn't save that much space, so maybe not worth it.
Out of curiosity, could you try compressing the already-compressed DNGs?
 
Recompressing using the converter...
@Bob From past experience, no meaningful effect.
 
Bob
@bwDraco Ah. Pretty expected then.
LZMA2 might be slightly better, but even then probably not by much.
 
12:42 AM
Recompressed, it is 1.43 GB. Huh.
 
Bob
Compressed data looks too close to random.
 
I guess I'll just run the data through the converter.
 
Bob
@bwDraco lol. so whatever Adobe's converter does, it's better than the camera?
I suppose that makes sense. Not much processing power in a camera.
 
@Bob Yup.
It's also much faster than 7z.
Plus, all the metadata's preserved (except for a few things added, but nothing's removed—checked with ExifTool)
I guess older images will be recompressed in this fashion.
 
>_>
I think my old workplace used to use that
 
Bob
12:47 AM
@bwDraco Huffman coding is pretty fast.
Their advantage is lossless JPEG takes into account some peculiarities of photos that a general algorithm like pure LZMA can't assume.
Now if only those could be combined with LZMA instead of the Huffman coding... that should be even better.
Or if there were some multi-image algorithm/format that could perform solid compression.
 
There's this paper (PDF), but I don't know if it's implemented, and also I think it's lossy?
"I know some of those words"
 
@BenN Lossless by default. Newer versions of the DNG format allow lossy compression as an option.
 
Bob
@BenN Pretty sure DCT is what lossy JPEG uses.
 
...oh
 
Bob
> We report a new spectral multiple image fusion analysis based on
the discrete cosine transform (DCT) and a specific spectral filtering method.
 
12:55 AM
RawTherapee has no trouble opening the reprocessed files, and they process just as the out-of-camera files would.
 
Bob
@bwDraco Ben's link isn't talking about DNG though.

A: How do I force single (only) channel audio in youtube/flash videos to play in both (left/right) channels?

user678104I found a solution (if u have this right ear/left ear problem), go to recording devices - from there your microphone (or line) from there advanced and 1 channel 16 bit 48000 hz (dvd quality) <3

o_O
My first instinct is "audio filter driver!"
 
hm
Actually
You're right
And I have an existing answer for another question that might work.
with some changes
 
If one channel is softer by x dB (perhaps 90-100, or some user-configurable value), duplicate the channel with the audio into the channel without.

A: I can't find a Mono setting for my computer

Journeyman GeekYou need a Stereo to Mono adaptor. Its a cheap/common arrangement of plastic and metal, that looks vaguely like a headphone jack that dosen't have a cable attached, and roughly as platform agnostic as it gets. You're probably looking for a generic 3.5mm to 3.5mm one, though RCA to 3.5mm and RCA t...

This would do the trick but I need to check the settings.
And you'd need to turn it off or on as needed...
 
1:40 AM
@Bob OVH's rescue64 netboot image has an up-to-date (one micro version off of the latest stable) zfsonlinux package :D
that's damn convenient
sadly efibootmgr doesn't work, but can't have it all
dd was both a good and a bad idea; it helped me mirror the partition sizes down to the block level, and worked for transferring the flash drive contents; but it sucks for ZFS because the pool's metadata got munged or something so I'm using zfs send and recv now
 
ouch
 
Bob
@allquixotic O_O
That's news to me
 
zfs send -R -e tank@migration | ssh root@newbox zfs recv -F -u -s tank
 
Bob
I was still doing the whole boot-to-live thing
 
@Bob same but they added it
might make your move even easier
 
Bob
1:45 AM
@allquixotic ah yea I had that problem. boot to debian to fiddle with zfs (installing zfs packages), reboot to ubuntu to fiddle with efi, rinse and repeat
@allquixotic if I decide to do it! :P
 
I'm not booted yet but I'm not entirely convinced that I'll even have to use IPMI to get into the BIOS
 
Bob
@allquixotic If you used the by-id setup then ZFS wouldn't be too happy about the drive serials changing.
@bwDraco This isn't something that you'd want to apply automatically, I think.
@allquixotic Fiddling with servers aside, what are the chances of you using the C# plugin? (read: should I bother with cleaning it up?)
 
@Bob modestly; if it works well enough and I lose my motivation to keep working on kynnaugh-cc, I might just take your plugin wholesale and give it to the user :P if you think it's possible for us to get it running cross-platform eventually, I'll definitely think about using it
 
Bob
@allquixotic Eventually? Yes. The only blocker at the moment is resampling and I'm sure I can get that working on Linux eventually, even if only by porting libresample to pure C#. It's not that long.
Everything else should be .NET Core-compatible, and the native interface binding doesn't look too bad (and Mono is a backup option). But it wouldn't be as elegant as the Windows mixed-mode assembly.
(actually, the only interactions required are passing samples in to the currently-working converter, and the function pointer to print text... everything else could be pure portable-ish C for all the difference it makes)
So... yea, I guess I'll be spending some time cleaning it up and adding logging/exception handling :P
But if the only thing wrong with the C++ version is FLAC encoding, it probably won't be too hard to fix either.
 
@Bob if you want, I can go through and attempt to do that
 
Bob
2:04 AM
@allquixotic Sure, if you want. Some things I was thinking of doing:
* Split GoogleApis off into its own project to reduce build times
* Merge PcmToFlac project into main one - not much in there
* Add NLog, log properly to file (especially the last-chance exception handler)
* Bundle DLLs as resources (might require a new project that just builds all referenced DLLs with nothing else, and some MSBuild script fiddling)
* Load DLLs from resources instead of external folder -- need to figure out how to detect the current assembly correctly...
Rest of it is just generally adding some try/catches around the place, cleaning up some debug stuff (like the task.Wait())
And of course things like printing the nickname with the message, maybe print something when an unintelligible message comes through...
 
Dog
Hmm, so AMD have some Ryzen gaming demonstrations out, as well as Ryzen + Vega systems
 
Bob
2:22 AM
@Dog Any good?
 
Bob
2:33 AM
@allquixotic Actually, would be good if you can check that it builds from the git repo :P
I've only tested x86 so far, too, but I don't think I have anything arch-dependent
 
@Bob >_>
does TS run on anything else?
 
Bob
@JourneymanGeek windows, linux, macos, x86, x64 for each...
 
Bob
@JourneymanGeek also since I'm dealing with native libs when I say arch I do mean the difference between x86 and x64
 
x86/windows makes sense...
ahhh
ok
 
Bob
2:47 AM
x86-64 if you want to be pedantic
it's more that ts3 on x64 will only be able to load a x64 dll as a plugin

Q: Is getting IN or OUT of orbit easier for the Space Shuttle?

Dat HaHere is a brief dramatic of the Space Shuttle launch and reentry: Launch : You get on this plane like thing that is strapped to an orange fuel tank that looks more like a huge bomb. The fuel tank is strapped to 2 missile looking SRBs that actually have explosives charge in them. Takeoff (YAY),...

I love that description in the question :P
 
@Bob no x64?
 
Bob
@allquixotic I've not tested yet, but if you select the x64 build config it should work
I need to install an x64 copy of ts3... again
will test tonight if I have time
 
User #1 (Kynnaugh herself) runs Windows 10 x64 with an x64 copy of TS3 (I'll be asking her to get the TS 3.1 beta)
that's what I'll provide her when I hand it over to her
 
Bob
grpc nuget package includes native libs for all arches on all three OSes
all my other libs are arch-independent
 
at least we don't have to worry about her having an up to date .NET version :D
 
Bob
2:50 AM
@allquixotic hm?
I pretty much always assume .NET 4.5/4.6 these days :\
 
@Bob if she had, say, Win7 or Vista, she might not actually have an up to date .NET
but I think Windows Update basically forces you into running the latest .NET on Win10
 
Bob
ah
yea, it probably does
 
oh and I asked her to check and she's running build 1607, in case it matters (it doesn't, though)
 
Bob
at least MS documents these things well msdn.microsoft.com/en-us/library/dn833125(v=vs.110).aspx
> Starting with the .NET Framework 4.6, a new 64-bit JIT compiler is used for just-in-time compilation. This change does not affect the 32-bit JIT compiler.
that's the only one that might matter
iirc RyuJIT had some bugs at launch
> All of these issues have been addressed in the new 64-bit compiler released with the .NET Framework 4.6.2. Most have also been addressed in service releases of the .NET Framework 4.6 and 4.6.1 that are included with Windows Update.

@JourneymanGeek ^ :P
(ok, ok, he only trolls meta/elections. still, wasn't expecting to see him there)
 
Well, no one ever accused he who shall not be named of not being smart.
Other things, sure
@Bob there's a theory he did it for the T shirts.
He seems to have stopped now that he's ruined it for everyone people in the primaries don't get em

9:44 AM
Cavil (and most other services related to my box) are back up on the downgraded SP-128-S and working fine :D (@Bob)
 
@Freedo some aspects of what you're asking worry me...
reflashing a router is risky
I don't know if the wan interface is getting the settings -> does the internet work?
 
!!info
 
Or how I should configure it -> should be in the manual? openwrt does have a gui now too!
 
or not

Someone did something similar to ninite for chocolaty.
might try it next box I build, If I remember.
Even if all it seems to do is string the command together for you
@Burgi ;p>
(also schnauzers are famous for their beards. So logically schnauzer means snout, colloquially referring to... Moustaches... Someone clearly hit the schapps...)
 
you could probably advise someone to rm -rf / and get away with it with that beard

its not even showing on my profile
 
@Burgi Did you try and wear it?
@Burgi If you ask a question about this on meta at exactly 12:15.xx you should get a secret hat (if it is upvoted). Be quick. You only have 2 minutes :)
 
its 12:16 here
