Списання вийшло з-під контролю: Росія зняла зі зберігання Т-54
Команда CIT отримала фотографії потяга, який везе військову техніку з Далекого Сходу. Ми ідентифікували їх як радянські середні танки сімейства Т-54/55: в одному ешелоні були і Т-54, і танки, які могли бути пізніми Т-54 або Т-55 (див. ілюстрацію).
Як стало відомо, нещодавно цей ешелон вирушив з Арсеньєва Приморського краю, де розташована 1295-та центральна база резерву і зберігання танків.

Israeli political and economic columnist Doron Peskin said that according to the data he received, 14 facilities in Iran had been attacked.
These are UAV factories, IRGC headquarters, Qods Force headquarters and other industrial facilities that possibly serve Iran's defense industry. The attacks were carried out using UAVs.


The IDF's special operation in the cities of Judea and Samaria (West Bank) against Iranian terror infrastructure continues.

The data-oriented programming that @BrianGoetz describes in… provides strong validation for the #Scala approach to data modelling, which combines FP+OO, that we've been using for a long time!
I hope that #Scala 3 will continue to push the envelope and explore new ways, which can then serve as an inspiration for languages such as #Java.

I think we'll have our say when it comes to taming side-effects (IOs combined with #Loom), handling context and metaprogramming.
Of course, for me Scala has an edge - the whole ecosystem is built on immutability-first, while in Java it's a much alter add-on.

But that's the price you pay for popularity, change becomes much harder. It's impressive that Java is able to introduce such changes so late.

A lot of companies hire devs in Eastern Europe in what they call "b2b", paying you a salary that is peanuts to them but might be better compared to other offers in your country of residence.

Most devs accept, because it looks convenient, but you can do much better! 1/3
If you accept a job as an employee, ok, but if they only offer you to go b2b, then that's contracting, and contracting rates should apply, not just a "salary" and whatever benefits.

Many companies offer diff salaries according to location too, even when 100% remote (BS)! 2/3
To give you an idea of the daily rate you should be asking for a Senior #Scala dev, here are some references.

UK: £700
EU: €800
US: $1000

Doesn't matter where you live. If you work for foreign companies as b2b, use these initial rates to start negotiating. Value yourself! 3/3

The Abecedarians, the first band alphabetically in my collection. I’m not sure I have listened to this since I bought it. Fac 117, is a 12” 45, just two tracks, electronic with nods to other Factory bands. No idea what happened to them.
#abecedarians #factory #factoryrecords ImageImage
Backstory: In an effort to listen to a wider variety of the music I own for the first half of this year I’m dedicating a week to each letter. I thought I’d start with the disc that has sat leftmost on the shelves since some time in the eighties!
A Certain Ratio. A couple from them today, between the two marking a huge change from fucked to funky.

Après des mois de travail à distance imposé, notre bureau #Montpellier se réinvente pour accompagner notre transition sur le modèle d'Hybrid Workplace : nouveaux espaces de collaboration et de visio-conf, nouveaux espaces de travail #flexoffice et nouvelle déco ! 🔽 thread !
Le télétravail existe depuis toujours à Hawk, mais force est de constater que durant ces deux dernières années il a pris une part prépondérante dans notre quotidien. Notre organisation future sera un modèle hybride où télétravail, présentiel et remote cohabiteront harmonieusement
Le flex office, pour ou contre ? Chez Hawk la réponse a été quasi-unanime : POUR 👍 ! Parfait pour booster le foisonnement d'idées et favoriser l'émergence de solutions innovantes.
Et pour soutenir ce changement, quoi de mieux que des nouveaux espaces de travail modernisés ?

#JSM2021 panel led by @minebocek on upskilling for a statistician -- how to learn??
@minebocek #JSM2021 @hglanz no shortage of stuff to learn. First identify what you don't know -- that comes from modern media (blogs, twitter, podcasts; groups, communities -- @RLadiesGlobal or local chapters; professional organizations -- @amstatnews ).
@minebocek @hglanz @RLadiesGlobal @AmstatNews #JSM2021 @hglanz What do the job postings require these days? (This is how the content for the @CalPoly stat/data science program was developed.)

Monads are monoids in the category of endofunctors - a #Scala 3 journey, tweet-size, no psychobabble

Read on 👇
You'll need to know some abstract Scala and heard about:
- type lambdas
- functors
- monoids
- monads

at least in the practical sense that I talk about on the blog and YouTube channel. If you haven't, go to the blog/channel and run a quick search. I have them all.
Step 1 - monoids

Monoids are glorified combine functions with some properties. You've seen this in Cats.

I am more and more hooked on the idea of using message-driven finite-state-transducers as a mathematical model to describe #DDDesign Aggregates. This would enable automated determinism proofs, unions, concatenation, projections, and any other operation that is available for FSMs.
A transducer is defined as a sextuple: (finite input alphabet / commands, finite output alphabet / events, initial state, finite set of states, state transition function (state, command) -> state / behaviours, output function (state, command) -> event). #DDDesign
I spent a bit of time implementing a very naive UserRegistration Aggregate based on an also naive generic transducer in #Scala, you can check ou…
It felt very natural to design it that way. Static types can already provide the input, state & output sets.

Looking around for how finally tagless might be different on #Dotty I found this talk that shows a number of applications of implicit function types.… #Scala3
He has written a post on this too that goes into greater detail "Revisiting Tagless Final Interpreters"…

A while back I said something to Adriaan in response to the community build drama that crossed a line. The comment was to the effect that he “seek professional help”. I want to make it clear that this was not okay and that I apologize for this behavior. I was very angry 1/3
and said a thing, and that thing was not a good thing. I hope you all can understand and forgive my behavior in the rest of that thread; it brought back alot of baggage I’d been working on sorting through, and I didn’t handle it well in the moment. 2/3
I’ve since spoken with a few folks at Scalacenter and I think we all universally agree it did not help things. I’m not making an attempt to erase it, just acknowledge it and move on with people having full knowledge that it was a mistake. 3/3

Little story about biases in technologies. Before I joined @wavesplatform, I thought that #scala is a very complex, non-obvious and little supported programming language, there is too much magic and you can draw ascii emojis with special characters in your code.
I heard and read a lot about troubles with #scala, and it looked reasonable. But as I dived in it (thanks to @wavesplatform deva and scala courses by @BinaryDistrict), I began to realize that these "troubles" are only my (and people in my bubble) biases.
In fact, scala is like any other popular languages with its own advantages and disadvantages. Same like #Java, #Javascript, #TypeScript, #Python in which I wrote before.

#Java's death will be due to SEO mess, lack of centralized docs, outdated tutorials & no one-stop-shop place to find it all


This site was supposed to be the answer, but it only raises even more questions. The information here is mostly marketing-related, and has pointers to other online locations, outside

Potential: very high.
Reality: waste of TLD.

The Java source, no doubt. Yet, devs who want to just learn/code Java apps will only find binaries downloads. Nothing else serves the average Java software developer. "Developer's Guide" is for contributors.

Potential: high.
Reality: confusion.

Why? Although concise, it requires in-the-know lore. What does "fold" mean? Which order are the params in? Why 2 arg lists? A pattern match _is_ a fold/catamorphism, it's just easier to read. In a team env, it's a no-brainer #scala
At work, we settled on pattern matching as "the" way to resolve an Option like 5 years ago, and nobody has wasted a single brain cycle on it since.
Beginners get a bit bamboozled by this sort of advice, and worry about whether they are "functional enough", which apparently involves using the most obscure available option for any particular use case.
