ohaideredevs··on Ask HN: Your favourite tutorial for total beginners?
As someone who is (was?) fairly good at chess because I grinded it in chess clubs as a kid, I can tell you that all the books are pretty useless and you just need to practice.

You CAN memorize common openings if you want, but I am not sure that's a good way to spend your life unless you are super serious about chess.

The sensor you linked is limited to SEAD missions in most occasions.

I am going to admit to moving the bar - but at this point you have MIG-31s in the air looking for SEAD and taking down any AWACS.

"I’m pretty sure that Russia understands very well that other than a nuke on Tel Aviv they don’t have the logistics to have an engagement with Israel that does not end in total humiliation and the destruction of all Russian assets in the region.

At the end of the day if push comes to shove Israel can push 400 aircraft into Syria’s airspace and countless ground assets the numbers simply don’t favor Russia.

The Russian navy is also not in a shape to engage, other than their submarine fleet any naval assets they put in theater would be likely targeted and crippled if not destroyed this also includes their aircraft carrier."

This discussion has nothing to do with Israel. It has to do with Russia not engaging US and ally Tomawhawk missiles, in which Israel is not involved.

"I’m pretty sure that Russia understands very well that other than a nuke on Tel Aviv they don’t have the logistics to have an engagement with Israel that does not end in total humiliation and the destruction of all Russian assets in the region."

Yea, but it can nuke Tel Aviv. And Israel can't nuke anything of consequence back, even with its illegal nukes.

It can also saturate all of Israel with conventional artillery. Even a fraction of its forces would overhwhelm the system immediately, and that's assuming it works against anything but SCUDs and slow moving toy rockets.

"and countless ground assets the numbers simply don’t favor Russia."

The last time Israel pushed "countless ground assets" into Lebanon to bomb their hospitals and destroy their tourist industry, Russian RPGs destroyed a number of Merkavas. Cry more about how those were "mobility kills."

In what magical world does an Israel vs Russia ground war "simply don’t favor Russia."?

"The Russian navy is also not in a shape to engage, other than their submarine fleet any naval assets they put in theater would be likely targeted and crippled if not destroyed this also includes their aircraft carrier."

Russia has the best ASMs in the world. This is widely accepted.

Your post is comical even before you consider that most of the technology Israel has is thanks to the USSR diaspora.

" Alexander Zasypkin, in comments broadcast on Tuesday evening, said he was referring to a statement by Russian president Vladimir Putin and the Russian chief-of-staff.

"If there is a strike by the Americans then... the missiles will be downed and even the sources from which the missiles were fired," he told Hezbollah's al-Manar TV. "

https://www.independent.co.uk/news/world/middle-east/russia-...

I am aware of what the source is. This did happen though, and you can find more sources if you want. If Russia had no intent, it shouldn't have bragged.

1. These were US missiles.

2. Russian government officials stated they would shoot them down.

3. Russia had NOTHING to lose by shooting down missiles in defense of an ally, e.g. no political risk.

4. Russia had everything to gain by demonstrating the capability to deter a NATO strike, especially given the context of using Syria to advertise its weapons.

Israel is a separate issue, if you want to discuss it. Very nice of Israel to get Russia's plane shot down by hiding behind it.

1. Let's stop re-explaining how radar works as an argument, everyone gets it. For those who don't - radar works like turning on a flashlight, end of story.

2. Non-SEAD RWR is generally limited to "There is light shining on me." Not where it's coming from, let alone providing targeting information.

ohaideredevs··on An F-22 Raptor’s Crumbling Radar Absorbent Skin
Detected with what, AWACS? Do you know how big those radar signatures are?
ohaideredevs··on An F-22 Raptor’s Crumbling Radar Absorbent Skin
I am with computerex. Your explanations are extremely simplistic and biased. S400s can toggle on and off, share data, have Pantsir systems around them, etc.

You ignore the same problems with air platforms emitting.

Your claim about detecting the data link is absurd.

ohaideredevs··on An F-22 Raptor’s Crumbling Radar Absorbent Skin
I don't agree with all the bashing of the S-400 here, but Russian performance has been "disappointing" in terms of demonstrating combat capability.

"The obvious question that remains unanswered is whether Russia chose not to engage S-400s, or was simply unable to, whether because of American nonkinetic capabilities impacting those system or some other reason. Given the pre-attack notice given by the Pentagon to Russian forces through a deconfliction line, as well as the fact that no strikes were targeted at the air defenses themselves, analysts lean toward the former."

https://www.defensenews.com/pentagon/2018/04/20/who-learned-...

In short, Russia has S400s in Syria. Russian government officials claimed Russia would shoot down the Tomawhawks. Russians knew the strikes were coming. Yet, they did not use the S400.

To me, there are no two ways about it - Russia did not have the capability to engage even the legacy Tomawhawk missiles.

I got that much from the article. Was interested into factors that got into it. Also "machine learning" is generally a cop-out term, what's your training set, etc, or is even a broad answer proprietary??
ohaideredevs··on Clearbanc raises $300M to fund more startups equity-free
"VC in the form of non-dilutive revenue-share agreements."

What if the startup can't pay for x amount of time?

"Coupling data and machine learning technology, Clearbanc is quick to make decisions about potential investment"

What does this mean?

"Money isn’t a magical cure all."

Yes it is. Workout. Dress well. Eat right. Learn things. Time to do so.

Also, I called out $400,000 a year, not $2000.

ohaideredevs··on Middle-aged vlogger who used filter to look young caught in live-stream glitch
1. If you have enough money to throw around $2,000, you should be able to invest in yourself enough to get real attention, not buy it. If you can't, due to some dysfunction, that's sad. Not sad in a derogatory sense, but sad in the sense that you are so *cked that even $400,000/year can't fix it.

2. If it's not play money, it's sad how irresponsible the person is.

This isn't exactly complicated.

ohaideredevs··on A Trump-era purge of military scientists at a legendary think tank
Correct. It was just an example that came to mind. There are plenty of streets, statues, etc dedicated to scientists however.
ohaideredevs··on A Trump-era purge of military scientists at a legendary think tank
The USSR also glorified scientists to a degree that is unheard of in the US. While people here grew up with Martin Luther King Ave, the USSR kids grew up with Yuri Gagarin street.

Furthermore, phds were available to people besides wealthy kids or those looking to commit economic suicide.

There were problems with the USSR, but education definitely surpassed US education in the 80s. Furthermore, what Kennedy tried to do with his fitness program was commonplace in the USSR.

I have used recursion two times irl outside of interviews.
ohaideredevs··on What’s New in ES2019
I can write things in Javascript 5x faster than I can write things in C#. I am finally convinced .NET Core is inferior to Node for that reason, unless I am writing something that needs to be super accurate/performant.

And it has brackets.

ohaideredevs··on What’s New in ES2019
flatMap is always so unituitive (not a word) for me for some reason. I messed with it a bunch in C#'s LINQ and RxJS and I already forgot the purpose. Not sure what it is that makes it so unnatural for me.
ohaideredevs··on Taleb is wrong about IQ
Right. That's a huge problem even when trying to figure out if your IQ changed over time. Even with Raven's progressive matrices, just knowing roughly what type of manipulations can be done to the shapes can help a lot with your score.
ohaideredevs··on Taleb is wrong about IQ
The ASVAB can be studied for and grinded, though, like the SAT, it would require more effort with a low IQ. Iirc the breadth is less than the SAT. Is there another test you are referring to in terms of this "IQ test proxy"?

For fair disclosure, there was a study which showed that as IQ decreased, the span of time for a perfect IQ score prep increased almost infinitely, as the low IQ kids forgot the material they already learned. Maybe I will look for it later, would be very relevant here.

ohaideredevs··on Taleb is wrong about IQ
'but my gut tells me that all of the people who think "genetics is destiny" are losers.'

Try doing a sport competitively at a high level, where the whole team is eating the same, working out the same, and some plateau at a 315 deadlift and start getting injured all the time and others keep going to 450 without any problems.

And that's ignoring obvious things like deformities, asthma, insulin resistance, etc.

ohaideredevs··on Taleb is wrong about IQ
I am not fully following what you are saying. Let's see if we actually disagree. Intelligence has two parts:

1. Crystallized intelligence - essentially your knowledge / what you have memorized (including useful heuristics, experience, etc). This can grow throughout your lifetime.

2. Fluid intelligence - in reality, this is basically defined as your "working memory", which is how many pieces of distinct information you can maintain in short term memory and work with. The magic number is 7(+-2). Anyway, this influences your ability to learn, since if you keep in mind what you just read/heard, you can connect the dots.

Pieces to memorize can be grouped to make them easier to work with.

As a result, an expert in a field will have pieces grouped and organized in long term memory, and WILL appear more intelligent than an amateur in the field, when discussing that field.

In my, subjective, experience this can be enough to work in one field.

When you want to be a Renaissance man, or compete at an extremely high level, low IQ chokes you. Even a difference of 10 points between 120 and 130 chokes you.

Hopefully this wasn't a rant and you know what I mean.

ohaideredevs··on Taleb is wrong about IQ
1. You may want to choose a less intellectually rigorous career if your IQ is low. Or you might get an early warning to work on factors you can control - for example the ability to focus, getting enough sleep, etc.

2. "With enough time..." is a totally irrelevant argument made by people who don't understand competition and how it applies to the real world, as in for scholarships, promotions, etc. Time is everything - and its a luxury. It also cuts into your free time heavily.

3. This is true. Except, when you read some code or a complex math concept, have fun if your working memory is sub-par and you can't even remember what the inputs to a function are.

"Its only important/useful subject for a select few people."

It's the exact opposite of that - it is applied to learning any field fast.

ohaideredevs··on Taleb is wrong about IQ
Raw capability has nothing to do with how that capability is applied. IQ is supposed to measure raw capability. Especially tests such as Raven's which focus on fluid intelligence.
ohaideredevs··on I thought I was being ‘blacklisted’, so I demanded to see colleagues’ emails
I agree with you 100%, but I think it's better to 'choose' to believe you can do better, despite knowing, factually, that you are just a product of your environment.

In other words, "I can improve myself" is a pragmatic outlook.

Of course, you can respond with "but you can't even choose that outlook", which I don't disagree with.

Thanks for the recommendation!
ohaideredevs··on Quantum Darwinism, an Idea to Explain Objective Reality, Passes First Tests
My comment isn't useful, but I really can't get a handle on anything "quantum" related. The only thing I sort of understand is that if you could entangle a massive amount of photons/electrons, you could have "quantum radar" which would be jam-proof.

I don't really understand even that though. Could you verify an electron reflecting back is entangled with an electron you have on hand, or are they all just "entangled" with something or "entangled" with some spin (which could be replicated)?
