First, you should probably add disclaimer that you work for Databricks.

Second, they really did not.

They came up with a test case of 1) create a table 2) merge into it 3) delete from it 4) delete from it 5) delete from it 6) delete from it (but call it "GDPR request" in chart).

This is a completely absurd workload that should give anyone a pause. In real world, Lakehouse tables are either appended to, merged into with periodic compaction, or dropped and recreated (using something like dbt). Running a delete four times is just bizarre, and making a general statement out of it is just suspiciously biased.

Of course it is very interesting coincidence that this independent company came up with non-realistic benchmark showing how better Delta is compared to major competitor, that everyone from Databricks is sharing everything.

Not a native Chicagoan here, but lived in the area for quite a while.

Chicago has not one but three distinct styles of pizza, the deep-dish which many think of as "Chicago style", the thin-crust with a relatively thin (compared to deep-dish, anyway) layer of sauce, cheese, and meats, and the square-cut tavern style.

All three are superior to anything the East Coast has to offer, IMO.

California Governor Teases Support for Digital IDs
As someone who lives in the outer edge of an Outer Borough, my experience is somewhat different - most slice places close fairly early (10 pm on average in my area, slightly later on weekends) and long before bars do. As a consequence, my go-to when out and about is a chopped cheese from the local deli/bodega.
There is a new failure mode I experience not uncommonly,

when 5G is available, but weak (or saturated?), my data performance drops off dramatically; my iPhone doesn't fail down, but keeps trying the 5G path even when it's not performing.

(I've also had this problem at the edge of WiFi range; data keeps trying to route over very low bitrate or packet-lossy WiFi... but if I turn off WiFi entirely, boom.)
Let's revisit your comment in a couple of years, when people actually have had the incentive to publish enough <math> elements out there.

If no one uses it, it will eventually get phased out.

I have just about a billion <math> elements in the arXiv preview site I develop:
https://ar5iv.labs.arxiv.org/

And that is just one site. PubMed will likely have more than that at some point:

They probably mean incremental builds, where the actual compilation doesn't overshadow the "coordination" work.

In my (artificial) benchmark, make scaled poorly, taking 70 seconds to process 100k C files worth of dependencies, vs. ninja's 1.5 seconds: https://david.rothlis.net/ninja-benchmark/

Most of make's time was spent processing the ".d" files containing header dependencies (Ninja has a special optimisation for these files, where it reads them the first time they're created, inserts the dependency information into a binary database, then deletes them so it doesn't have to parse them in future invocations).

In real world projects, you often end up "abusing" make to add behaviour such as detecting if the compilation flags have changed, and this can make your makefiles slower; whereas ninja has those features built in. Apparently this made a big difference in build times for Chromium (where ninja was born). See this comment by the ninja's author: https://news.ycombinator.com/item?id=23182469
> Future you will be very happy you did.

The future could also look like large batteries on-site that charge slowly, and then provide power at high amperage when needed, like slowly compressing a spring, then suddenly releasing it.

This is already what Electrify America and Freewire (https://freewiretech.com/) are doing with EV Fast chargers when the electric utility can't provide a higher power connection in a reasonable time-frame. As battery prices drop, that could be a viable way to power heavy home appliances.

I just moved mine to the middle of the bottom floor of a 2 storey home. It took some work and there is lots of fire safety code to adhere to but it wasn’t a difficult job if you can do basic jobs around the house. Mine was a 160mm circular steel vent which is typical here.

With an external vent it’s also easy to put the fan on the roof or attic instead of in the hood, to reduce noise inside.

An indoor-only hood with a charcoal filter is the alternative but only reduces odor. I couldn’t imagine not having an external vent from the kitchen. Super cheap but massive quality of life improvement.

This is not completely true... there were many cases where repair technicians went looking through peoples personal data when the computer (or tablet, phone,...) was brought in for repair. With an inability to physically remove the hard drive in some computers (ahem, the fruit ones), encryption is the only way to keep your data safe when you have to give your device to someone else (even if for repair).
Considering that both Google and Apple are cardholding members of PRISM, it sounds like a bit of a frying pan vs fire situation to me.

Yeah unfortunately sal passed on maybe 7 years ago? But his grandson now operates it and was working under sal for quite a while before sal passed, and I didn't really notice a difference in the quality of a slice after the grandson took over.

That's what I said: At best they can consume/embed them and perhaps compile to them.

That is mostly correct: psychologist do not prescribe, psychiatrists do, as they are in fact medical doctors.

In my case psychologist made the suggestion I had ADHD after 2 years of therapy, so they knew me pretty well by that point. It all made sense to me, and I went to a psychiatrist to get diagnosed and medicated.

Had I gone to a psychiatrist directly, they probably would have prescribed an antidepressant without spending 2 years getting to know me.
3D printing is great for prototyping, and for small production runs, but economies of scale are not in favor of 3D printing for mass production. The material deposition rate is too slow, and the machine cost is too high, compared to traditional manufacturing methods. I have one part that I designed several years ago which is part of the APU installation on a certified aircraft. The part we flew during flight test was 3D printed aluminum (AlSi10Mg). The turnaround time from completing the design, to having a completed, inspected part ready to be installed, was about a week. For a machined part, the turnaround would have been about 6 weeks, and about 6 months for a cast part. But then when we looked at manufacturing methods for the production part. 3D printing directly in metal was the most economical method for up to 10 parts, because there is no up-front tooling cost, but the recurring cost of both the raw material and the machine time is very high. For 10 to a hundred or so parts, the most economical method was investment casting using a 3D printed wax preform, and for more than 100 or so parts, the most economical method was to buy traditional permanent closed-die tooling for the casting.
I think part of the problem with that pitch is that the cost of an IT integration in this industry could pay for a lot of people in Asia to manage a forwarding operation in Excel. Ocean carriers don't have like, APIs. It's all custom integrations with EDI, SOAP, or CSV-over-FTP and you have to have a lot of tedious meetings with them to figure out how to map out and interpret the data they can send and receive.
This is a great guide. One word of warning: it's not the shop tools that will cost you real money over the longer term, it is the tooling. It isn't rare at all to spend double or more on tooling than you did on your CNC machine, especially if you bought it second hand. So keep a sharp eye out for local machine shops going out of business and ebay to score tooling in quantity, sort out what you think you'll need and sell the remainder. That's going to cost a very small fraction of what you would spend otherwise.

To give you just one example, a pretty common 1/2" dia 3" long quality endmill will easily set you back $40 or more.

And you never have enough clamps and hold down gear.

I find it amusing how everyone in software keeps touting a shortage of "talented" developers when there is no evidence. There's an army of experienced engineers in developing countries and each year millions of software engineers enter the job market each year.
In my mind, Flexport is part of the "real" economy of moving atoms. They don't fall into the more fluffy "we are a startup that helps other startups start-up". I wonder if this is an early sign for a rough recession that spills outside of the current VC-backed tech slowdown.
New Flutter Tools on GitHub
As part of the company’s continuing efforts to support the global development community, Concepta Technologies is ringing in the new year by doubling down on its commitment to the transformative capabilities of open-source technology.

Over the past year, the team has published 4 projects to GitHub: a scalable enterprise development platform (Rockets), a design system API for Flutter (Mix), a Flutter Version Management tool (FVM), and a desktop interface that supports a more rewarding Flutter development experience (Sidekick).

These open-source projects aim to make the unified, multi-platform future Concepta envisions more accessible for dev communities and business owners across the globe. Some of the specific benefits include:

- Flexible, agile development capabilities
- Reliable access to a proven, tested code base
- Cost-effective scalability and growth
- Collaborative and community-oriented
- Significant boost in end-to-end development speed
This game looks super exciting! Unfortunately, I have a mac :<.

So, I install sbcl, installed quicklisp and then used quicklisp to install your game after cloning and cc'ing into your directory. It looks like your game would work if you (or someone) looked into why your "Harmony" sound engine isn't working (line 28-29 in your package.lisp file). I attempted to load from your github/Harmony directory and this is the error -

* (ql:quickload '(harmony cl-mixed-coreaudio))
To load "harmony":
Load 1 ASDF system:
harmony
; Loading "harmony"

#<THREAD "main thread" RUNNING {7008640253}>:
Unable to load any of the alternatives:

I tested the other audio implementations suggested as well and they don't work either. Is there a way to play this game without sound? That might fix the problem. I don't know how much I'm willing to dig into this, because cl-mixed is it's own library and it looks like it would start to become a rabbit hole.

It looks cool though!
Right, if you want `value` to be part of the public interface of your component you need to add a value property to expose it.

The industry spent a non-trivial time trying to maintain diagramming back in the waterfall days under UML and we really struggled to find a decisive solution.

As other posters have mentioned there are serious issues with having auto-generated and authoritative architecture diagrams. The biggest problems include maintenance burden (did you upgrade the diagrams?) and automating layout.

Personally I find the least ugly solution is to just draw some low-effort arrows and boxes when you need them and (for the most part) discard the diagram once you're done.
The C4 model (https://c4model.com/) is great for architecture diagrams. You can use different tools to generate them. Here are the ones I've been using:

Completely orthogonal to yours, but the undergraduate text "Operating Systems Concepts" by Silberschatz et al. has always been good.

Every edition features dinosaurs, which totally relate to the concepts of CPU scheduling, IPC, memory management, etc.

Whenever I see mysterious Enterprise pricing and that's the only tier with SSO...

The conditions of the living quarters for the workers for FIFA on the world cup builds are horrific.

Plus, they wouldnt pay the workers, would seize their passports and beat them.

No safety equipment, and extremely hot working conditions. Some of the temps were as high as 125F and these guys are doing really hard physical labor.

> Seriously, get a nice gas range and a high end copper pan and cook with it - you'll be amazed.

I cooked on gas for 25 years, including with all sorts of pots/pans. It was great and I preferred it greatly to resistance electric stoves. And then I switched to induction and couldn't be happier with both the cooking performance and the indoor air quality improvement. You (and many others) aren't concerned with or don't believe in the air quality problems of burning gas in a house. To each their own!

For my part, I tell everyone I know to maximize ventilation if they are cooking indoors with gas, and to try an induction stove to see if it works for them.

> When I'm not using gas to cook you'll find me outside burning wood fires to cook with.

That has nothing to do with the discussion about induction, but thanks for sharing, because I also love cooking over burning wood! We're more alike than you think!
>Because HN is basically filled with Boomers at this point, maybe most commentators don't realize that there are different segments of young people.

Perhaps I'm naive, but I think companies are doing massive layoffs these days because of some sort of "domino effect".

There are companies out there who would love to lay off half their staff, but in regular times they couldn't just do it (because it wasn't a common thing, and makes them look "bad"... everyone would protest). But since nowadays every damn company is doing massive layoffs (and not unknown companies, but companies like Twitter, Facebook, Google, etc.) then they take advantage of the situation and proceed to do the same.

> While we are looking forward to what’s to come in 2023, we must also make hard decisions necessary to set us up for long-term success.

This could have been said any damn year in the past, but massive layoffs is the latest trend, so why not.
