Throwaway acct. sort of. Not so much anymore. More like pseudonymous. Because of privacy. Trying to offend equally.

My northstars: without privacy, there cannot be freedom; affordable access to quality education should be available to everyone ; baseline healthcare should be available for everyone, without insurance, at an affordable cost. These are or should be civil rights issues.

rixrax··on ExifTool CVE-2021-22204 – Arbitrary Code Execution (2021)
So how do I know if there is bug bounty available for vulnerabilities in exiftool? Or ghostscript? Or ffmpeg, openssl, gnutls, sox, or any number of other packages I may be using?
rixrax··on AI-Powered Nvidia RTX Video HDR Transforms Standard Video into HDR Video
I recently had some old super8 films shot by my parents scanned into 1080p resolution in ProresHQ. Because of the poor optics of the original camera, imperfect focus when shooting, poor lightning conditions, and general deterioration of the film stock, most of the footage won't get anywhere near what 1080p could deliver.

What I'd like to try at some point is to let some AI/ML model process the frames, and instead of necessarily scaling it up to 4k etc., 'just' add (aka magic) missing detail into 1080p version and generally unblur it.

Is there anything out there, even in research phase that can take existing video stock, and then hallucinate into it detail that never was there to begin with? What NVidia is demoing here seem like steps to that direction...

I did test out Topaz Video and DaVinci's built-in super resolution feature, both of which gave me a 4k video with some changes to the original. But not the magic I am after.

rixrax··on Oh My Zsh
I backtracked all the way to Bash. Because I seem to write some amounts of bash scripts, it seems living inside bash is helpful. And it's really not much I feel like I am missing in my use from zsh (or fish). Bash even supports CTRL+R for history with search nowadays.
rixrax··on Google Cuts Jobs in Engineering and Other Divisions
Or having only ever worked at FAANG(s), many of them completely lack the skills that would make them effective as an entrepreneurs and it would be nigh useless to try to incubate new businesses out of them. Maybe. Not all. I am thinking of traits and skills such as actually talking to your users, selling product to customers, doing things small scale, being able to work without huge back office support, not having KPIs to game, and such.

rixrax··on Liero – Sling'n'shoot Worms Game
Loved playing Worms as a kid, not so much Liero. But before Worms, it was really Scorched Earth[0] that got me introduced to the genre. And with which I must have spent untold hours.

rixrax··on Midjourney v6
When (if ever?) will midjourney support Dall-E style prompts where you can reason about the created image with the 'AI' instead of just trying to engineer your prompt to generate desired output?

rixrax··on A small warning about UDP based protocols
This is a bit similar to roll your own crypto conversation. It is fun, and a great way to learn. And once done, you should do well to never deploy your own crypto in any real life application.

Friends don't let (or shouldn't at least) friends roll their own protocol over UDP either (or IP; I mean why not?). There are very few apps that have such an explicit requirements that they can't do away with TLS over any number (==2) of existing, and well known transport protocols (e.g. TCP, maybe QUIC). For presentation layer, instead of implementing their own spec, most should probably stick to Protobuf[0] (or some of it's derivatives[1]), and encode the application data into JSON.

Check. Protocol design done.

rixrax··on Russia 'Coup' Live Forecast
This. Especially now that after Putins speech/plea on national TV[0] for the army to put a stop on the rebellion, Wagner in telegram appears to have stated: “Putin made the wrong choice. ... Soon we will have a new president".[1]

rixrax··on Russia 'Coup' Live Forecast
Will current regime resort to use of nuclear weapons against Wagner formations as they approach Moscow? After all, the state and the power regime are facing an existential risk.
rixrax··on Regent – Electric coastal travel
The underside of the plane, and especially the part that 'drags' underwater - have you had any trouble with the sealife or other underwater objects? I would think bumping into large sea lion, shark, whale or even a large school of blue rockfishes might be unpleasant (to sealife, the plane, or both)?
rixrax··on YouTube tests blocking videos unless you disable ad blockers
- Ads crank up the volume to 11.

We were watching Eurovision singing contest the other day from YT and my gawd was that annoying. Adds in the middle of every song, volume being cranked up for the adds, and as a icing on the cake, probably due to bug somewhere, the playback went to pause after each ad (iPhone airplaying to AppleTV).

rixrax··on Finland becomes the 31st member of NATO
For anyone hailing from russia to be taken seriously, can you please answer these basic questions first: 1) Is Ukraine a sovereign country that belongs to the free people of Ukraine?, 2) Who does Crimea belong to?, 3) is russian army committing war crimes in Ukraine, and 4) are you personally supporting the russians war of genocide on Ukraine?
rixrax··on Silicon Valley Bank Tanked, Dragging Down 500 Israeli Startups
I don't think SVB going bust is generally a big problem for a foreign startups that banked there. This is because typically(?) they are structured so that their US subsidiary has account there, not the main company. And especially if the US subsidiary is on the red, the US accounts for the foreign startup pretty much hold enough cash to do next payroll.

What these Israeli startups appear to have done is something entirely different and I truly sympathize and feel sorry for them for all the money lost. One might even argue that 'no good deed goes unpunished'.

rixrax··on What does Silicon Valley Bank’s collapse mean for the financial system?
Sort of related question, if you have a brokerage account in a bank that goes the way of the SVB, what happens to the securities account?

Will it get liquidated and you will then eventually be paid some cents on a dollar of your brokerage accounts value?

rixrax··on SVB in talks to sell itself after attempts to raise capital fail
"As of December 31, 2022, the amount of estimated uninsured deposits in [SVB] U.S. offices that exceed the FDIC insurance limit was $151.5 billion. [from total deposits of $173,11B]." [0]

rixrax··on Does Google need a new CEO?
I think you nailed it! I think there is a bit of cognitive dissonance here because a lot of the workforce at Google (and indeed at other FAANGs) are people who have worked their entire careers at Google or similar companies and now their endless summer is coming to an end. Kids that went from college to free food, latte bars, arcade rooms, 20% own projects and such are now waking up to a new reality of their first real down cycle. Profits are down or at least not growing, and they have become sacrificial lambs at the altar of capitalism, where you are measured against the value you produce, not the coolness of your projects. So it goes.
rixrax··on Cloudflare mitigates record-breaking 71M request-per-second DDoS attack
>> The block $insert_country IP range "solution" is an outdated mentality that should have died off in the 90's.

Maybe so. But it works really well. After blocking certain countries IP ranges / ASes, >70% of abuse we had to deal with just vanished.

Also there are other reasons to block: since the russians attacked Ukraine, business I work with no longer does business with russia, belarusia and few other countries as a matter of principle (and because of sanctions).

rixrax··on tcpdump is amazing (2016)
Sometimes when no other options exist, and I need to capture untrusted traffic as root, I use 'tcpdump -i eth0 -s0 -n -w some.pcap' to save the packets to a .pcap. Just recording the frames shouldn't (invoke any parsing code although I have never actually checked). Then I open the .pcap with wire/tshark or even tcpdump in some safer sandbox.
rixrax··on Lytro Unlock – Making a bad camera slightly better
Nice to see old Lytro hardware brought back to life.

When they were launching the company, I was so excited about the possibilities. Maybe naively, I was really rooting for being able to take a photo, and then in their software (and later in Lightroom) be able to slide/brush-in/out points of focus. Alas, all we got were these gimmicky square pictures that you could click to bring various parts to focus.

rixrax··on My coffee maker just makes coffee
In last 10 or so years I've gone a full circle with coffee makers (manufacturers rejoice!) in a quest for better coffee. From Moccamaster, to Keurig, Nespresso, french press, fancy capucino machine or two, and now back to filtered coffee /w Wilfa Classic.

At the end of the day, it turns out I am drinking it for the effect, and quantity (as in volume of liquid, more is better). Although lately I've found some decafs that produce a rather pleasant brew. Filtered coffee from the 'right' (for me) ground coffees seem to hit right balance between ease of use, speed, and taste.

And then there are some studies indicating that filtered coffee might be a bit healthier[0] than other forms.

rixrax··on Wells Fargo Penalties Since 2000: $22B
But look at Bank of America[0]. 4x that meager $22B of WFC. Or Chase[1], which is only slightly worse than WFC. BK and USB are almost poster childs with only ~1B of penalties each[2][3].

rixrax··on Apple TV+ to adapt William Gibson’s cyberpunk novel Neuromancer
But if their adaptation of Foundation is a sign of things to come, we should hope it's not Apple TV+ that is going to produce any of these movies/series. Yes, that's what I really came to say here, they gave Foundation to some movie industry bureaucrats that A/B tested the storyline on some Joe Hillbillies and completely butchered the genius of Asimovs novels.

rixrax··on Classic 50mm “Normal” Lens
My cell phone has become my normal lens. New phones from both Apple and Google take such a good photos that literally all my street photography is shot with them. I'll grab my trusty A7r4 /w either wide or very long variety of lenses if I will be going to some special place etc. with specific purpose of shooting something that is (in my opinion that is) worth recording in the detail only achievable with this gear. But other than some far and few grand landscapes or wildlife, most of my most amazing(?) photos nowadays come from my cell phone. Case in point - was driving last night along the city street and was passing this church/graveyard which just looked amazingly spooky in the dark/fog/street lighting; stopped my car in the middle of the street, rolled down the window, and snapped couple of (raw) photos with the phone before driving away. Because the phone is with me all the time, it has become my new normal lens.

rixrax··on What it feels like to be bullied out of a job you love
Absolutely. Or to put it another way, loving your job is great, but being jealously, madly in love should be avoided.

I've sometimes wondered if there should be term limits on most jobs? E.g. no more than 8 years in any one company, and maybe no more than 3 years in any one position. Something like that.

rixrax··on TV backlight compensation (2020)
I wonder if this is so 'generic' that e.g. AppleTV could add support for this? Take a photo of your TV with an iPhone when AppleTV is showing test image. And then the AppleTV output is calibrated appropriately to compensate for uneven backlight.
