throwaway_ab | 4 months ago | on: Azure hit by 15 Tbps DDoS attack using 500k IP addresses

Not sure how this would work, if you blocked those IPv6, the mostly innocent companies and people that are now blocked will be in short order getting a new IPv6 assigned by the ISP after a support call.

I was under the impression that these botnets still rely on vulnerable computers, which have a human that will be calling support asking for the issue to be resolved.

Then it needs an ISP to figure out the issue and ask the client to sort out their compromised computer, but unlikely the ISP will stop a paying customer from internet access especially if it's not clear why their original assigned IPv6 is blocked.

throwaway_ab | 1 year ago | on: North Korean IT workers have infiltrated the Fortune 500

Yeah this is true and a good point. As an Australian when the government passed that law it hurt so much, like a betrayal of enormous magnitude, it's disgusting.

I suppose one difference is that I can fight the government legally on the issue and am more free in many ways to resist, especially as I'm not employed by the state.

But I do agree, on the scale (0-1?) of how much your government can take away your liberty (when you haven't committed a crime) and compel you commit crimes, most western countries probably sit around 0.01 to 0.05 maybe, North Korea sits around 0.98 to 0.99 and Australia probably 0.4

Thanks for bringing that up, Australia seems to be the test state for how many draconian laws a "free" society will bare, and it is terrifying.

throwaway_ab | 1 year ago | on: North Korean IT workers have infiltrated the Fortune 500

A flagged post mentions this is racist and typical anti immigration rhetoric.

That's not true, there are only two types of North Korean people you'll meet, either those that have defected and escaped North Korea or those that are agents of the state of North Korea.

There are very few defectors in existence and once they escape they're given full South Korean citizenship. This article is not about those people.

The vast majority of North Koreans outside North Korea are not defectors, instead they are controlled state assets. There are no North Korean people outside the country that are free citizens. Every single North Korean authorised to leave the country is working directly for their government often to raise money for the regime, to steal IP, to infiltrate for some nefarious purpose.

Having one of these North Korean active assets in your company is extremely dangerous, your business is now at risk of leaks, theft, or worst something being modified like added vulnerabilities that could be exploited later in cyber attacks.

So no, this article is not racist at all and really has nothing to do with the recent political situation.

throwaway_ab | 1 year ago | on: Artificial intelligence is losing hype

I find LLM's great for:

- Getting over the blank canvas hurdle, this is great for kick starting a small project and even if the code isn't amazing, it gets my brain to the "start writing code and thinking about algo/data-structures/interesting-problem" rather than being held up at the "Where to begin?" Metaphorically where to place my first stroke, this helps somewhat.

- Sometimes LLM has helped when stuck on issues but this is hit and miss, more specifically it will often show a solution that jogs my brain and gets me there, "oh yeah of course" however I've noticed I'm more in than state when tired and need sleep, so the LLM might let me push a bit longer making up for tired brain. However this is more harmful to be honest without the LLM I go to sleep and then magically like brains do solve 4 hours of issues in 20 minutes after waking up.

So LLM might be helping in ways that actually indicate you should sleep as brain is slooooowwwwing down

throwaway_ab | 1 year ago | on: Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane

A few thoughts:

- Enable fall back controls where the pilot can input "traditional" controls when the more advanced system is degraded, even though it's all fly by wire their should still be inputs that fully mimic a traditional cockpit and ability to use this system should be allowed if the pilot requires it.

- Drop any focus or marketing on getting more people flying, if the ease of use of your aircraft is such that pilots who otherwise would not be qualified to fly now can fly, this is a recipe for disaster.

- Instead, focus on bringing a higher quality aircraft to market for pilots who want a more capable system, this cannot do any harm imo.

- Any system that lowers mental workload so that more focus can go into other areas of flying is welcome, just ensure there is always a method to fly the aircraft without the "auto" magic, there should always be controls that give raw control if needed even modern fly by wire commercial airliners have this fall back ability.

How would a server/workstation like this be setup?

I thought you could only use the vram on the GPU, so for 700GB you would need 8-9 A100 nodes as 2 only gives 160GB.

I've been trying to figure out how to build a local system to run inference and train on top of LLM models, I thought there was no way to add vram to a system outside of adding more and more GPU's or use system ram (DDR5) even though that would be considerably slower.

throwaway_ab | 1 year ago | on: How Meta trains large language models at scale

I'm only aware of Nvidia AI Enterprise and that isn't required to run the GPU.

I think it's aimed at medium to large corporations.

Massive corporations such as Meta and OpenAI would build their own cloud and not rely on this.

The GPU really is a shovel, and can be used without any subscription.

Don't get me wrong, I want there to be competition with Nvidia, I want more access for open source and small players to run and train AI on competitive hardware at our own sites.

But no one is competing, no one has any idea what they're doing. Nvidia has no competition whatsoever, no one is even close.

This lets Nvidia get away with adding more vram onto an AI specific GPU and increase the price by 10x.

This lets Nvidia remove NVLink from current gen consumer cards like the 4090.

This lets Nvidia use their driver licence to prevent cloud platforms from offering consumers cards as a choice in datacenters.

If Nvidia had a shred of competition things would be much better.

throwaway_ab | 1 year ago | on: How Meta trains large language models at scale

I think it's likely Nvidia's GPU's, many of which are $50,000+ for a single unit, far surpass Google's custom silicon otherwise why wouldn't Google be selling shovels like Nvidia?

If Google had a better chip, or even a chip that was close, they would sell it to anyone and everyone.

From a quick search I can see Google's custom chips are 15x to 30x slower to train AI compared to Nvidia's current latest gen AI specific GPU's.

throwaway_ab | 1 year ago | on: Most of Europe is glowing pink under the aurora

In the dark notice how much light comes from a phone and how much that illuminates the person holding the phone.

A car headlight shining your way from hundreds of meters even over 1km will often illuminate that person far more than their phone screen.

So if the phone screen is enough to undo the hour long eyes adjusting to the dark duration, then the car headlights at almost any realistic distance causes an undo.

throwaway_ab | 2 years ago | on: Intel Brags of $152B in Stock Buybacks. Why Does It Need an $8B Subsidy?

For them to be effective at returning money to shareholders, the action of buying stock is intended to take stock out of supply thus increasing share price value. Exactly as you say.

Yet, this is clearly a form of stock manipulation, as it's an action to manipulate the share price.

Whilst it is stock manipulation, it's debatable if it should be legal.

I believe it should be legal, it's an efficient way to increase share value without adding to someone's income, thus often carries no immediate taxable obligation.

However one could argue that these methods of moving wealth around without taxable events triggering adds to the fuel for calls to tax unrealised gains on all stock.

So in the long run we are all worse off.

Those laws will likely come regardless, as a way to fight the billionaire class, so stopping stock buybacks at this stage is unlikely to do anything.

throwaway_ab | 2 years ago | on: The feds' vehicle 'kill switch' mandate is a gross violation of privacy

Focusing on privacy is a weak angle of attack in this case. The issue of privacy is solvable anyway so time spent on this argument is ultimately time wasted.

The real issue here is the issue of our liberty being violated in a substantial way.

The ability for the state to remotely kill your means of transportation, thus remotely controlling our freedom of movement, is a new dystopian level of government control.

You might be wondering how is this different from the current system, the government already has the power to determine who can drive.

A few things:

- The current system works solely via the legal system. The law determines who can drive, there is no technological system to force compliance, yes you can be pulled over by the cops, but this is a case by case process that can't be applied to entire swaths of the population.

- a kill switch allows the possibility that transportation is denied to entire regions, specific minorities, a government could use this power to control people in ways make the power imbalance between state and individual even more extreme.

- The kill switch is a constant threat against our freedom of movement.

- The system could be abused or hacked, exposing us in this way for more power is abhorrent.

throwaway_ab | 2 years ago | on: iPhone 15 Pro facts and estimates

Saving 20 grams of stationary mass is equal to saving possibly 200 grams in quick movement, such as taking the phone out of a pocket quickly. This is going to be quite noticeable. Add in to this the authors calculations of rotational inertia savings of 15% the effect might be even more pronounced.

So when moving the phone from pocket to quickly see a message or phone call, those savings reduce the weight of the phone during this motion by almost the weight of the phone itself.

Definitely noticeable.

-----

A few years ago I tried to work out the stationary weight limit of my roof rack on my 4wd, for example if I wanted to mount a rooftop tent with two adults (I'm overweight at the moment) and wanted to know if my size was an issue. Assuming a stationary weight of tent and other stuff and me and my partner I pushed my estimate to 400kg.

The roof rack is rated at 100kg carrying capacity.

What does 100kg equal to when going up and down sand dunes?

I found a forum post where someone worked out with calculus the "weight" that 100kg turns into 700kg - 800kg whilst off-roading aggressively, the roof rack experiences almost 80% of a ton due to the acceleration/deceleration pressing into and away from the car in a vertical diagonal motion.

With that I could rest easy knowing I'll never approach those numbers whilst the vehicle is stationary.

------

I figure that quick motion moving the phone from pocket to in front of your face involves similar forces. Intuitively this checks out. Hold your phone in front of your face. Now move quickly side to side. Your phone is easily exerting 1kg of force as you wave it around.

That 20 grams saving will make a huge difference.

throwaway_ab | 2 years ago | on: Plants can detect sound

Sure, any interaction between our bodies and the universe can be considered an interaction of touch.

All of our senses involve some form of matter/energy touching us.

- Photons touching our retina cells...

- Molecules touching our taste buds...

- Air molecules touching our ear hairs...

- Some amount of matter or electromagnetic energy touching our skin...

- Molecules touching our olfactory sensory neurons...

IMO we do not describe them as all just being touch as:

1) Saying they all are touch doesn't help differentiate the different senses and how they work.

2) It's a bit too low level.

This is similar to saying there is no need for the separate disciplines of biology & chemistry because it's all just physics after all. So we might as well dump those subjects completely.

Imagine being introduced to science at school but there is only one subject, physics, so you only "eventually" learn chemistry & biology through the lens of their physical atomic interactions.

Imagine trying to describe a cell through the frame of atomic interactions and no higher level abstractions allowed.

All science being physics is far less useful than being able to step over the base level going's on and make higher level abstractions so that you work at the appropriate "topology/focus/subdivision" level for the scientific discipline in question.

Anyways that's what I thought of when considering all senses are touch, it's just a bit too low level and ambiguous to be useful.
