Ha! It’s also going to be funny when he discovers going over India requires parallel diplomatic clearance by his embassy and if he misses the slot, bye bye record. Repeat problem for multiple countries along the route.

They tried a variant of this in Australia for a short period of time before realising IP blocking accidentally takes down thousands of legitimate businesses on shared hosting.

They didn’t repeal the law but instead worked out better ways of using the existing powers after a review.

This would be great for most projects as Swift for example is abandoned & 6+ years since last commit.

reading the source it looks like for some browsers that rate limit url updates, it has to use a different way that nukes your back button ability.

As an Australian I’m disappointed in the lack of the key word ‘cunt’ in the graph. Unless perhaps it’s zero.

If you have a modern iPhone and don’t want the crazy hacks, a very very simple but effective tip is to power off your iPhone when exiting the aircraft. When the device powers up it is in “before first unlock” mode and is severely restricted in what it can do. The attack surface area is significantly reduced. They’re not going to burn one of their $100,000 per install exploits on your BFU phone the same way they do with a full physical access unlocked paid exploit.

Also lockdown mode to reduce attack surface area.

dhsysusbsjsi — Tue, 24 Dec 2024 07:16:15 +0000

Yes and it was one of the best years of my life. I made more money from submitting vulnerability assessments than my day job. I’m structuring my life to do this again.

You get a little lonely as you don’t get the social fix from hanging out with work folk.

Overall the health benefits are immense. Both mental and physical as you have more time to look after yourself.

The success comes in the form of creating a void for opportunities to present themselves. I ended up doing things I never thought I’d do. Some were fun nothing burgers, and others were financially successful. The important thing is I got all my daily chores done first and only coded if I was “bored”. Coding/hacking came last.

Excuse my ignorance but how big of a lookup table would you need to achieve the same outcome ?

Ben from UncharteredX has a good video on these drill samples, but does not buy into the mainstream acceptance of how they were made. In fact the granite core samples show continuous grooves and you can calculator the pressure per turn the mechanism was under, and it’s not really able to be done easily.

What I haven’t seen discussed here much is optimising for developer maintenance. I think the author’s solution is great for this; it’s easy to understand and each move has a bit pattern. Easy to debug. Somebody taking over in the future will understand this compression.

If on the other hand you can squeeze another 10% storage from Huffman encoded inverse tree lookup tables that only neckbeards understand, you’re limiting your pool of people able to do maintenance on this system in the future when the author is long gone.

Easy - make mental health non-reportable to the aviation authorities. Instead, the shrink can report if they think there is an issue to public safety, as they would currently do for patients at risk of harming the public.

The problem is people think that any 'solution' to this problem needs to be perfect. "What if we never find out this guy was a problem" comes up. No. You just need to make the next system net _better_. Don't delay forward progress because the next step isn't "perfect".

Great article, but unfortunately the lying is entrenched culturally. The regulator is so distrusted it can never change.

For example in Australia I’ve heard multiple cases of somebody proactively seeking counselling for help dealing with temporarily stressful situations such as divorce, then being grounded at work, and the regulator (CASA) denying medical clearances. This increases the stress.

Every time some senior person proclaims “it’s okay this time - report your illnesses”, it never is, and we go around this circle again and again. I will personally never report my medical history accurately to the regulator.

dhsysusbsjsi — Tue, 07 Mar 2023 12:37:04 +0000

I own a Model3 LR and an ICE. The Tesla is significantly more costly with insurance & tyres. It has also had a bunch of teething problems like broken camera, charging micro (stopping all charging). Fixed under warranty. 20,000km in 2 years.

My ICE has basically had no issues in 7 years (77,000 km) except the cost of oil change once a year. But recently it developed a rattle, which I had investigated, resulting in a $2,000 invoice just to investigate (at one point it wouldn't start at the garage, and they just kept throwing parts at it to get it working again). Now it's got a rattle and won't sell. It will cost more than it's worth to pull the engine apart to find the problem (probably timing chain).

Both are going to have issues. Overall though, for me, I'm more sensitive to time. So I'm scrapping the ICE for a ModelY.

I’m 92kg +/-, 187cm. Run 2x a week 6.5km like clockwork, plus extra fitness 2-3x a week. So heavy guy. I do about one 1/2 marathon a year and train up to 15km. Heart sits at 180-185 by the end. The 18km is definitely a hump where it’s not aerobic fitness but feels like need to push through a mental wall. I don’t think I have the physique for a full marathon without proper preparation but may try next year.

Stop eating carbs about 2 months before. I did this and went from a 2:06 to 1:58 with minimal training. My body carried several kg less weight and felt like it could consume its own fat energy more efficiently and I didn’t get the 2/3 slump.

I also started last, ran down the 2hr pace guy, then tried to stay 100m ahead of him. It felt primal being chased down by somebody and kept the mind sharp.
