> From what I heard, feature films regularly spend $1 mio+ on renting CPU power alone.

Renting CPU power is typically an indication that rendering was severely underestimated and a million USD would be an extreme example. That money could buy multiple racks that would be in use for four or five years.

> rendering is heavily optimized to not jump around. It's the same for AI convolution.

I wish that were true, but with the exception of Disney's internal renderer only a few small parts of most renderers end up architected for this. Don't forget that most actual production renderers are multiple decades old.

> While the inner loop might not fit into a 128 MB cache, it would fit into 512 MB cache. That would cause the memory bandwidth to raise from ~20 GB/s to ~500 GB/s.

This doesn't really make sense. Instructions are very small and the data they operate on are very large. Each core will be doing different things to different data and the total L3 cache will be used by all of them. I'm not sure how you are getting these numbers, but they don't seem grounded in reality of real software and lots of cores. L3 cache typically has bandwidth in the same order of magnitude as memory, while Intel is claiming to increase that by 3x in the article.

> So if memory bandwidth is the limiting factor - and it is for many convolution and rendering workloads - then a 10x speed-up is possible.

This is very far from the truth, especially for rendering. Most renderers hop around him memory to trace rays through acceleration structures, actual geometry, geometry attributes and texture lookups. Also I'm not sure how 3x the cache bandwidth translates to 10x program speed in any scenario.

> Oh and the development tools I'm referring to is V-Tune & Amplify, i.e. the Intel tools to make sure your loop is using all the tricks to avoid pipeline stalls so that RAM bandwidth becomes the limiting factor.

Yes, those exist, but they don't have anything to do with the article or cache sizes.
The article makes several huge leaps of faith and the intended audience is definitely not intended for the typical Ycombinator crowd. To clarify:

1. All his examples are large companies (eg Tesla & Amazon) with internal demand for components which a custom ASIC could provide some cost efficiencies). For a startup to compete for such business, they would have to be proven, well capitalized and/or have unique IP.
-- It is hard for a startup to land business with these giants. --

2. He ignores to other SoCs as a potential alternative. The IoT segment is full of standard parts and it would be a challenge for a chip design house to compete unless the company contracting the development has high enough volumes to offset the NRE cost.
-- see point #1 above --

3. SoC is generally bad business for startups. There is a lot of IP that needs to be aggregated. Your value-add is small unless you have fundamental value-add. And there is high risk in of integrating someone else's IP as it is not in your direct control. If you need cutting edge IP like DDR6 memory controllers, SERDES interfaces or PCIe Gen4, it's usually out of reach unless your startup has mid-7 digit back accounts.
-- Sourcing IP can be expensive and time-consuming. License terms are typically not favourable to small startups and require "large" upfront payments --

4. The examples cited have long product life cycles. Most startups excel at Greenfield or new market opportunities where the risk is higher and lifecycles are much shorter.

5. I would not do a design in nodes larger than 45nm today. The PPA (Performance, power and area) differences are small compared to your engineering and EDA tools cost.

Basically the article is an advertorial, self serving and not appropriate advise for startups to follow. I agree with noone10101's comments below.
Interesting topic but this article was tedious.

The UserPatch mod for the older CD release is really interesting, as it modifies the binary to give a lot of new AI script functions. Some of the ones for customized targeting have almost a declarative, map/filter feeling to them, such as `up-filter-range`. [1]

I think the newer versions of the C++ compiler are much more optimizing today than compared to what what Age of Empires II released on. I'd imagine it wouldn't be possible, or perhaps a lot harder, to make these AI mods with the Steam re-releases.

If you're working with more than a couple of people it can be worth running an audit on your code, including the libraries you're using. Even if the libraries themselves have permissive licenses, they may inadvertently include bits of SO code.
It could have the opposite effect too. For every person with an outstanding student debt, there may be another 3 people who absolutely do not want to "pay" someone else's student debt. Those who have gone to great lengths to successfully pay off their student debts might be particular vehement against such policy.

In the current version, you can execute `compress_chunks` on each of the data nodes and enjoy those same savings (and will work transparently with queries, as before).

In subsequent releases, we'll add full support of compression, e.g., just create a compression policy on the access node and you are off and running.

So nothing, really, because none of that would have made any difference to China at the time of Mao.

They could not have cared less about 'sanctions', which seem like a meaningless threat at the time of the Cold War and Maoist China.

The West was and still is supplying weapons to their neighbours, which is not very important, anyway.

As for 'dissident movements'... This is not a South American banana republic. The CIA probably did try things at some point but clearly to no effect because there is no 'dissident movement' of any scale.

From a historical point of view the question I am very interested in is why did Mao stop short of retaking Macao and HK, and of taking Taiwan in 1949?

They refrained from taking Russian colonial possessions in the North, which is understandable. But I am puzzles about the rest.

For HK and Macao, perhaps he wanted to respect treaties because he also wanted to rely on treaties regarding Tibet (which all the powers recognised as Chinese by previous treaty), I don't know.
I would expect checks for Xcode to go through xcselect rather than a simple directory check. Installing the command line tools (sudo xcode-select --install) might actually be a better idea to test this.

Oil rigs are towed to location using steel cables. Steel wire rope is substantially stronger for its weight and for it size but generally harder to work with than plastic things of similar capacity.

I think what you are referring to is the TimescaleDB real-time aggregates https://docs.timescale.com/latest/using-timescaledb/continuo...

FWIW if you're not using algebra to write your software you're not quite doing FP just yet.

Doing math on software to make new software is the overlooked part of FP in my opinion. You hear about "first-class functions" and "referential transparency" a lot but not as much about "equational reasoning".

That's an extremely impressive list of titles.

As a hobbyist game dev I'm looking at moving to a multi-platform 2D game engine (last few games were done for the web using Phaser). The two engines that seem interesting are Monogame and Godot. My limited understanding is that you get more tooling and ready-made things with Godot compared to Monogame. I'll have to do another deep dive of these two engines soon.

I'd like nothing more than for hydroxychloroquine to be an effective treatment, so we can end this crisis. It should continue to be explored and investigated. At the very least we might learn something new that will help with its known effective use in treating malaria or autoimmune diseases like lupus.

But it should never have been turned into a political football, and the person responsible for that is unmistakably the POTUS.

Because there is no profitable market for it. The number of people who would be willing to pay the $1000+ that it would cost to produce a board like that in low volume just aren't there, in part since you could build a dramatically more powerful x86 machine for less money.

Some Tech Startups Are Thriving During Shutdown
As second-time founders and having gone through a couple of startup accelerators, we understand the immense power the network brings.

It takes a strong network to build and grow a successful business. A great network helps a lot in an overall journey of the founder - in hiring, finding your first customer, help you grow your business, etc. and generally these have a snowball effect where the advantage grows exponentially over time.

Now the startup ecosystem has evolved a lot in the last 10-15 years where most of the startup founders get access to a strong network through startup accelerators like YC, TechStars, 500 Startups, Village Global, etc. and it continues as they raise more funds through VCs.

But when we embarked on a journey to create a bootstrapped business this time, we realized this network effect is largely absent. Yes, there are plenty of resources, forums, and groups out there, but that's not the same as having a strong network or a community. A strong community is more than just a group.

So we asked ourselves how can we create this strong network for the Bootstrappers? That's what we are setting out at District. Starting July 11th we are getting together a small group (no more than 50 people) of very ambitious early-stage Bootstrappers together and help them with various resources, workshops, weekly goal tracking. We will also bring strong network leaders, to help you through this journey so you can learn from them.

We are looking for people who can add value and bring diversity to the community. We are opening up our applications soon and we'd love you to be one of the first.

Join other founders so you can be notified when it opens up!

That is not true anymore. With 20.04 it supports hybrid graphics just fine. The only issue I had was sharing cuda and OpenGL context since GL ran on the Intel card. This should not be a concern for most people I assume.
It's really very sad, because users have no idea what is going on and there is no incentive for bad programs to improve (actually, there is generally incentive in the opposite direction, because it's work to write well-behaving apps). Users just know that they need to keep buying new computers and that their battery life is worse, but they can't figure out why so they point fingers at everyone but who they should actually be blaming.

> I much rather build upon the relative robustness and consistency of the sql I got so far, than JSON that is all over the place.

Yup.

> almost every time I made a JSON column in Postgres for the sake of saving time in the past, it slowed me down almost immediately after adding it

Backs my experience fixing software from companies that had terrible data loss issues after these JSON hacks reared their ugly head.

I am not saying JSON does not belong in a DB - I have many well tested and audited code that does do that. What I am saying is I have seen things go wrong far too much, for me to trust that someone who proposes that approach to actually know what they are getting themselves into.

Plus, it's way cheaper to use a custom built KeyValDB that actually supports object semantics if one does not mean to use RDBMS semantics.

< Another thing is that they're specific kinds of tensors on the manifold. Tensors represent basically all the information we might be interested in about a manifold (for example, its curvature). Differential 1-forms are "dual" to vectors and are therefore important to building more complex tensors (higher tensors take in some number of vectors and 1-forms and output a value).

This was how differential forms were introduced in the course. I understood all of this from an algebraic standpoint, but I was lacking any geometric intuition for differential forms whatsoever. Say you have a k-form on some manifold and you evaluate it at some point which gives you an alternating covariant k-tensor. Then when you evaluate that at k tangent vectors at the point you get a scalar, does this scalar have any geometric meaning? Does it measure anything? Later when we did Riemannian manifolds and introduced the volume form that was at least a little more intuitive, as far as I remember, but general differential forms were intuitively a complete mystery to me.
Also I kind of got their usefulness in an algebraic sense when we did some typical vector calculus calculations using the concepts of divergence and curl, but I didn't have much intuition for these concepts since I don't have a physics background and only worked with vector fields in this abstract setting.
Unfortunately we did not cover De Rham cohomology. Thanks for your answer, I will take a look at planimeters.
