I wrote a little email screed to a friend about the risks to bitcoin from advances in quantum computing and was reminded of a paper I presented at DEF CON 9 back in 2001 on Quantum Computing, back then limited to 8 qubits.
The remotely relevant bit was what I really hope someone (other than me) will call “Gessel’s law” (after Moore’s law: P=2(y/1.5)) on the power of quantum computing, at least once, as I believe it may have been the first presentation of the formulation: P=22(y/2)
How did my predictions hold up over the last 20 years?
I estimated a crossover within about 10 years, or 2011. D-Wave claimed to offer a quantum computer 15x faster than a classical computer in 2015, 3-4 years later than I predicted. Google claimed quantum supremacy in 2019.
In 2020, D-Wave claimed to have a quantum computer with 5,000 qubits, slightly ahead of my prediction of 4,096 by 2021 back in 2001.
A “fun” part of organizing an MP3 collection is harmonizing the tags so the datas work consistently with whatever management schema you prefer. My preference is management by the file system—genre/artist/year/album/tracks works for me—but consistent metainformation is required and often disharmonious. Finding metaharmony is a chore I find less taxing with a well structured tag editor and to my mind the ur-meta-tag manager is MP3TAG.
The problem is that only works with that dead-end spyware riddled failing legacyware called “Windows.” Fortunately, in Linux-land we have puddletag, a very solid clone of MP3TAG. The issues is that the version in repositories is (as of this writing) 1.20 and I couldn’t find a PPA for the latest, 2.0.1. But compiling from source is super easy and works in both Linux Mint 19 and Ubuntu 20.04 (yay open source!):
- Install pre-reqs to build (don’t worry, if they’re installed, they won’t be double installed)
- get the tarball of the source code
- expand it (into a reasonable directory, like ~/projects)
- switch into that directory
- run the python executable “puddletag” directly to verify it is working
- install it
- tell the desktop manager it’s there – and it should be in your window manager along with the rest of your applications.
The latest version as of this post was 2.0.1 from https://github.com/puddletag/puddletag
sudo apt install python3-pyqt5 python3-pyqt5.qtsvg python3-pyparsing python3-mutagen python3-acoustid libchromaprint-dev libchromaprint-tools libchromaprint1 wget href="https://github.com/puddletag/puddletag/releases/download/2.0.1/puddletag-2.0.1.tar.gz tar -xvf puddletag-2.0.1.tar.gz cd puddletag-2.0.1/ cd puddletag ./puddletag sudo python3 setup.py install sudo desktop-file-install puddletag.desktop
A nice feature is the configuration directory is portable and takes your complete customization with you – it is an extremely customizable program so you can generally configure it as fits your mental model. Just copy the entire puddletag directory located at
Ruby is a horrible nightmare language, like almost all modern languages. They try to be so clever and modular, but end up making a maintenance hassle as various modules come and go, dependencies break, and the developer community moves on to the next shiny thing that claims to be the best thing to happen to programming since C.
If you get a bunch of
"invalid option: --no-rdoc" errors, it is because sometime in the last few years
--no-ri were depreciated in favor of
--no-document. And, apparently, just recently builds started barfing on the deprecated errors. Building universally with these options is a pretty standard thing as it vastly improves build time and the rdoc system is a whole big kettle of annoying weirdness you just don’t need to wade through.
Now Ruby, being oh-so-clever and friendly, has all sorts of places where these might be set universally or semi-universally. The references will tell you about
/etc/gemrc, but only by doing a
grep -FrHIis 'no-rdoc' * at / did I find these sneaky little bastards:
basejail/usr/ports/sysutils/vagrant/Makefile:RUBYGEM_ARGS= --no-ri --no-rdoc -l --no-update-sources \
basejail/usr/ports/Mk/Uses/gem.mk:RUBYGEM_ARGS+= --no-rdoc --no-ri
basejail/usr/ports/devel/ruby-gems/Makefile:DOCS_VARS_OFF= RUBY_SETUP_OPTIONS+="--no-ri --no-rdoc"
After converting those to the “new” “better” “shiny” version of the config option string did my gems build.
While there may be people who actually like Windows 10, there are also many people who aren’t interested in fully exposing every part of their digital life to for-profit mining as means of offsetting Microsoft’s declining profits in the desktop OS business, and if you’re one of those, fighting Microsoft’s truly viral (and malware) marketing techniques is quite a hassle. It appears there may be an easier way.
Micrsoft has finally provided an “easy” way for people to turn off windows OS update (e.g. from 7.x or 8.x to 10) from happening automatically and without user intervention (and frequently in outright defiance of clear user intent because profits first!)
The short form for people who are comfortable with some of the internal workings of Windows is:
Search for "edit group policy" and open the editor then follow the selection cascade as: Local Computer Policy -> Computer Configuration -> Administrative Templates -> windows Components -> Windows Update ->> Turn off the upgrade to the latest version... ->> [x] enabled
The longer instructions are at this link: https://support.microsoft.com/en-us/kb/3080351
I suggest doing this and then downloading and installing the following program. It will pretty much do the same thing but it also checks to see if Microsoft has already kindly filled your hard disk with malware without your permission and offers to delete it:
Note that my previous posts about removing specific “updates” are still relevant. The above should prevent windows 10 from auto-updating but Microsoft has been pushing updates with “telemetry” to Win 7 and Win 8, which are also spyware and are tracking you and reporting your usage patterns back to Microsoft without telling you or asking you.
Welcome to the new economy: you’re the product.
It only got to 47.5C today according to our new roof-mounted weather station. It seems to be about 3 degrees cooler away from ground level, but we’re still down about 4-5 degrees from peak temperatures.
I came home to find that Tortuga, one of the stray cats that’s adopted us, had developed a nice open wound on her forelimb. When I left two weeks ago it was a bit swollen, presumably abscessed, and then drained. I’m sure it was really gross. Anyway, the cat just couldn’t get enough licking that yummy puss and had turned the wound into a nice open sore.
The vet gave me some antibiotics and antiseptic cleaning solution and this lovely and stylish Elizabethan collar that Tortuga clearly just loves to wear. Her thought bubble probably reads something like “once this collar comes off and I can get my teeth around your neck, you better sleep lightly.”
Interesting bit of trivia, @phragments, how one can drive through the three capitals: but one only takes 90 seconds…
