The relative performance of float32 vs int32 is heavily dependent on the specific operations you care about and what hardware resources (i.e. area, power, std cells) you have available.

While floating point numbers can be cleanly split into a mantissa and exponent, adding floats requires shifting the exponent, which can be an expensive operation. Each portion of a floating point arithmetic operation is also implemented with integer arithmetic, which limits the performance spread. Many floating point operations require significantly fewer bits though, which can lead to major speedups.

On the integer side, the serial carry dependence mean ripple-carry adders are usually a bummer, but there a ton of carry-lookahead variants that can lessen the performance impact of that dependency. If you have several integer additions at once, you can use a carry-save variant to only pay that serial cost once all of the additions are done. Finally, if you are willing to significantly change your integer encoding, there are tools like redundant number systems[0] that allow you to move around the traditional trade-offs for arithmetic circuits including completely removing the serial dependency on carries. That said, if you require rescaling your fixed-point numbers during the computation, the fixed-point implementation will require more integer operations than floating-point operations.

All of this is also quite dependent on the overall architecture of the chip too, since the number of integer units vs float units and how data is moved around can have a way bigger impact on performance than how each arithmetic operation is implemented.

Very cool. Is there a web version as well?
I wonder why it‘s „just“ called a theory. At least for the central european bank this is the reality.
In germany the term is „Giralgeldschöpfung“ which apparently translates to „giro money creation“ - so it seems we are talking about the same thing.
When i read about it a few years back and talked to people about it, was surprised how little people know about this. Especially the smart people from the financial industry that i know, or bankers… i just stumbled upon it accidentally.

I am not educated in the financial workings, but the recent history shows that the people in charge might seems educated, but shouldn‘t be trusted.

There is too much of a gap of interests and understanding between the financial industry and the actual economy.
Property-Based Testing (PBT) is another pragmatic formal method that can be used in combination with more traditional example-based TDD.
I have tried installing Pop!_OS 21.04 on 2 distinct models of computers - it would fail silently (the installation process sort of ends suspiciously quickly, then it won't boot) so I had to use Ubuntu instead (it still installs and boots without any problems). Pop!_OS 20.10 worked fine.
> everything I eat I prepare myself from fresh ingredients

Nestle owns a lot of brands in the "ingredients" space too, unless you mean you are making everything from scratch. Buitoni pasta, Maggi bullions and soup bases, Carnation condensed and powdered milks, and Garden Burger meat alternatives are the ones I can think of off the top of my head.
Freicoin was invented earlier and died faster than any other cryptocurrency. In my opinion the idea of an anti speculation cryptocurrency failing is exposing the entire cryptocurrency space for what it is: gambling.
Sorry if it wasn't clear, but the problem of land use is not legal. Indeed you can build your city whenever you have enough will to and it has never been a problem. The problem is that humans destroy the ecosystem of the place they live in. And if humans use 100% of landmass then 100% of planet ecosystems are destroyed.

>> How could it be worse than doing time?

Ask his lawyer. It is likely not a matter of which is better or worse punishment. It is a matter of risk, risk that one punishment will spin off into others. Someone out on community service, effectively parole, can get in trouble for all sorts of minor things (ie not showing up for work). A kid like this on community service will likely break some rule, resulting in further punishments. Jail time is not only shorter but places less responsibility on the individual. His lawyer might therefor have suggested, given the high likelihood of him breaking rules on community work, that jail time was the safer option.
Just +1ing that these numbers are things I've seen personally. I've also seen ~3%.

Your audience matters immensely. And you can't always predict your audience - a lot of initial growth is somewhat organic, and that can take many forms. If you've somehow managed to make huge inroads to Philippine-island knitting clubs and have heavily invested visitors trying things out and checking that box... rejoice and make the most of it.
The first thing I do on a fresh Ubuntu is to purge away everything related to snap.

I tried PopOS at one point, to see what it was about. And, I honestly don't understand what it adds to the table. It felt like many minor things were changed to be different, but overall it had the same things I wanted. After being annoyed for a couple of days, I installed Ubuntu, removed snap, and everything is pleasant again.
I agree. I found this painful to read.

> They let him do whatever he wanted. If he felt like gaming, he’d boot up Windows. But more often he chose Linux, his go-to operating system.

Why is this important? This is exactly what I do. I also frequently use a VPN, yet it's treated in the article as if the use of such technologies automatically labels you as some sort of nefarious hacker.
Java is technically compiled into machine language, it is a matter to chose the JDK that offers such options, many people don't, but that is their problem, not lack of options.

JavaScript interpreters that people actually use, have a JIT inbox.
And FTP is already on its way out.

Modern networking looks funny. UDP as a baseline protocol. Wireguard and HTTPS/3 are built over UDP. Custom protocols are built over HTTPS/3. I think that it's good and simple suite of protocols.
Setting up a Kickstarter for this kind of defeats the utility of the device.
I like the idea. I use Go a lot but always go back to Python for quick scripting (often in Jupyter Notebooks). If it works like advertised, it could be really interesting!
They should filter some of it through PM Kishida's kidneys.
Wow, I'm currently writing a USB drive with the 21.10 beta, considering switching from Ubuntu.

If I keep using it I'll support them. I want a company that cares about desktop Linux to succeed. For all the good they've done (and that Pop is building on), Canonical don't seem to give a stuff about consumer desktop Linux anymore.
I agree, Computer Space just wasn't fun. It did not capture the core gameplay of Spacewar! And it wasn't just gravity. It could have been just fine without gravity if it had been polished, better controls.

Something completely off topic about the content of the article but not when it comes to the title.

Github search is a great resource for any engineer. It has saved me so many hours trying to figure some API out when I know there must be so many people who have used it before.

I switched from xubuntu to pop about two months ago and generally have a good time using it. I like the tiling wm and had to configure very little and except for the crappy WiFi stick everything worked out of the box.

Being the idiot that I am I thought I wouldn't need a swap file and now everytime my ram is full my system freezes entirely.
Bad news is: a quantum computer will not crack hashes faster.
There isn't one because of the VR bubble. People spent too much trying to build the VR version of it, only to realize that VR is too limited and people don't want VR. HighFidelity was supposed to build something like that but they scrapped the project completely. Opensimulator is still the only open source alternative.
A problem close to my heart. Good search is certainly still too difficult to pull off for small teams, and this was one of my motivations for building and open sourcing Typesense[1].

Most people think of search and immediately think of large data sets, but the problems that plague smaller datasets are equally interesting. It's less about performance and more about relevance. For e.g. searching across multiple fields for a compound query like "taylor swift style", requires breaking the query into segments (taylor swift | style) before searching for the appropriate fields. There are also a class of problems that traditional search engines that rely on BM25 or TF-IDF for ranking cannot reliably solve (e.g. searching on small texts like titles) where you have to consider distance between matching words (which TF-IDF and BM25 miss). Lastly, there is also personalization which is almost always left as an exercise to the reader :)

First thing would be to see if Elasticsearch works for you, because it will for many applications.
Poor translation, but the meaning is obvious:

Either way. Use whichever works best for your target hardware.
I think, it would benefit readers to mention more than the 2 mentioned groups of the search-related software - there is a lot of new generation tools and libraries like MeiliSearch, Typesense, Sonic, Toshi, Bleve, ...
The simplest advice to engineers would be to not think elastic search as some black box that will solve all of your search problems. In fact, if you've never implemented search before it's the last tool you need. Postgres full text search is all you need. The most important thing in search is to surface relevant results and no one can quantify relevancy. It's as unquantifiable as it gets in technology. You need to understand what results are relevant for your users and find a metric that would work to rank accordingly.

The first two pre-date the time one could assume disks and memory were large enough (help2 is from 2001; that’s Windows XP era; it required 1,5GB _disk_ space and 64 MB RAM) and people had an always-on internet connection, so data shipped on CD (later DVD; compiled help evening floppy disk, I think) and had to be relatively small.

The third has special features for CLI programs, and is much more recent, so I can see why they didn’t want to build on earlier work.

The fourth is the modern way. It makes fixing help easier (no updates to send out), and effectively doesn’t have space restrictions.
A free text search on your content via a search input is the killer app of a search engine but it is not the only app of a search engine.

A search engine (and its backing index), just like a relational database, is a technology that allows you to build all sorts of solutions on top of it. Nobody says don't use a graph db because Facebook already has the best friend of a friend solution you could hope to find.
The difference between a laptop and a "portable desktop" is you close the lid of a laptop and put it in your laptop bag, stand up and leave. Be it from the plane, train, cafe, or anywhere else you please.

If a computer cannot simply have its lid closed before being placed in its bag it simply is /not/ a laptop. It should not be advertised as a laptop and it should have a big f&%ing warning on it telling you that it will break if you treat it the way you expect to treat a laptop.

Either Dell didn't know they messed up their laptop design and when they found out made the decision not to recall the faulty product or they knew and sold it fraudulently. "This is a laptop - but we know it isn't and will break if you treat it like one warranty void, sucks if you believed us."

Either way Dell made the decision to screw their customers. There's no getting around that. It's a choice they made.
Some recent news out of the commercial VPN universe... From a cryptographer professor at Johns Hopkins: https://twitter.com/matthew_d_green/status/14493567426896896... Kape, an Israeli 'adware' company that renamed itself to distance itself from its prior history as an adware company, recently bought up ExpressVPN and several other services and rebranded itself as a VPN services company. Kape also bought VPN ranking websites and juiced the rankings (into positions #1 and #2) for the VPN companies that it just bought: https://restoreprivacy.com/kape-technologies-owns-expressvpn... I suspect that Kape is probably a CryptoAG repeat - https://en.wikipedia.org/wiki/Crypto_AG - and is doing double duty for the US IC along with the Israelis, but it could be just a pure Israeli shop too.

I have started installing Fedora on computers I set up for my family, and it has been great! Everything works out of the box and every app is avaliable in the app store thanks to Flatpaks. Skype is just a click away, which used to require adding extra repos from Microsoft.

My father, who barely knows how to operate a computer, has been using it for years without the need for support. No forced updates/reboots. I only run a system upgrade every year or so, which also is a one button operation whitout any problems. It is a super stable experience for him as a user and me as an admin.

I tried PopOS for my SO, but it was to nerdy and the GNOME experience was to tweaked. I then went for Fedora and she likes it much better, comming from mac-land.
That's an interesting analogy. I would say even the market share is similar to Esperanto and English, respectively.
As a long time lurker of your work, and someone who works on a fair number of search engines myself - I'm curious, how well does TypeSense handle code search (punctuation, etc.)?

Yeah, but I think jeppester also hits on a wider, and valid, point: OS X has got it easier, only needing to provide very limited hardware support.
Absolutely this. The firmware contains copyrighted data and that data is also critical to the functioning of the Switch, both emulated and real.

Modern handhelds are not like the older ones, there's actually an OS involved and a lot of per-system settings that uniquely identify your Switch-- especially when it connects to Nintendo's servers or authenticates if you're allowed to play a digital game.

I've used BEE editor many times before, and I've always always loved it.

When I found out the company was founded in Italy (my home country) I was very pleasantly surprised, as tech companies with such well designed products are very rare over here. Building a friction-less editor for engaging, reliable email layouts is a complicated engineering problem, and what your team built is absolutely outstanding.

Good job, really :) the company success is fully deserved.
It is absolutely very dependent on your specific hardware. I would expect dedicated digital signal processor chips to almost always support a high-performance fixed-point multiply-add instruction. In contrast, I would expect chips targeted and HPC or scientific computing to be much more focused on double throughput than anything else.
Yeah. Absolutely. There's plenty of merits in the pursuit.

But products are constrained by requirements and most of the time the manager thought search was in there, after a little talk, search was not in there any more.

There's resources, deadlines, budgets, contracts to satisfy, blah blah blah. The insight is this costly feature can usually be shaved from the requirements with a little conversation.

A big secret of "10x" programming is realizing "90%" of the work isn't truly necessary.

But yes, search is totally a fantastic thing to do if you have the space and expertise to do it.
Sometimes you just need to do something different then working for a boss. We are in a privileged position that some can work 1 month and use it to live 2 comfortable months off it. Why not take some risks in life.

I'm really struggling to understand the marketing from Honeycomb. They have a lot of reputable and smart staff, seemingly making conflicting public statements.

For example, in this post, the author describes how expensive cardinality is for TSDB, but doesn't really address how Honeycomb's column store implementation efficiently stores data with full cardinality anywhere near as cheaply.

Like, I fully appreciate how having traces and structured event logs will improve observability, but this 'actually, Prometheus is expensive too' angle is weird, and their pricing page's 'starts at $100' doesn't really make it easy to compare.
