alexis2b··on Ask HN: Earning 100k EUR in Berlin?
Swiss salaries on the German-speaking side for senior engineers are in the 120k-160k bracket (Zürich area, depending on skills and domain). Speaking German natively will also score you above a lot of the local developers (expats from many non-German speaking countries). Taxes are much lower and quality of life is great, but also more expensive. PM me if interested and I can hook you up with local recruiters. Remote work might be possible.
alexis2b··on GCompris Celebrates 20 Years
For the non-French speaking audience, the name GCompris reads out “j’ai compris” which means “I understood”. Nice pun!
alexis2b··on Odin: «Cloud-based» replacement for troubled F-35s software
ODIN actually seems to be a combination of hardware and software used for mission management and maintenance of F-35s. It is due to replace ALIS which is presented as bloated and buggy (« 4,700 open deficiencies »!).
alexis2b··on Ask HN: What's some “one sentence” wisdom you've learned or created?
_ « if you can not afford to buy it, you certainly can not afford to build it »_

To eager business leads saying that a software or service is too expensive and we should build it internally instead...

alexis2b··on Reviewing the worst piece of code ever
It does not really matters, the purpose of salting is to avoid rainbow table attacks (i.e. comparing against precomputed dictionaries of known hashes). (Edit: typo)

alexis2b··on WeWork from Home Now
Maybe a counterpoint to the article conclusion (for the longer term). With the Covid crisis many companies discovered the benefits of remote working (or at least the lack of all the negative aspects they were fearing). My bet is that many more companies will adopt remote and distributed teams, which could be bullish in the long run for co-working facilities.
alexis2b··on Ask HN: Good ways to capture institutional knowledge?
A famous example is the (in)famous trader Jérôme Kerviel who was deemed responsible for a 4.9 billions euro loss at Société Générale.

Having worked in Middle Office before being promoted to the Front, he had a really good knowledge of how operations and risk management worked in the bank (plus some still working write accesses to specific systems) which allowed him to mask his very large positions with fake opposite trades that he was putting in every day before the nightly risk snapshot and cancelling before they could be confirmed.

The guy basically did not take any holidays in two years - otherwise his large positions would have appeared on Risk radar pretty quickly...

If you are into those stories and want much more details than my poor summary I really recommend reading the SocGen post-mortem investigation.

Disclaimer: I worked at Société Générale during the Kerviel era - also there is a lot of controversy in France about how much the bank knew and let things happen (Kerviel was making a lot of profits - until he wasn’t) and if that was used to cover subprime related loss - this post does not represent an opinion on this case!

alexis2b··on Demonstrating the inferiority of multi-tasking by simulation
TL,DR: multi-tasking generates increased lead time, reduced flow and more missed opportunities leading to inferior value generation.
alexis2b··on Revolut Oct.30th incident post-mortem
TL;DR; non-backward compatible schema migration (dropping an « unused » column) triggered errors on the previous authentication service version during rollout
alexis2b··on Insomnia is now part of Kong
It is - the pun is about GETting some REST ;-)
alexis2b··on Why some software developers hate Agile
Except maybe for the point that humans are notoriously bad at estimating creative work and biased in the shorter side... So taking estimations as commitment is indeed a way to short-hand the one estimating. Thus the rush when you realise your naturally optimistic estimate became a deadline.
alexis2b··on Ask HN: Why is .NET not popular with startups?
StackOverflow being a prime counter-example...
alexis2b··on Ask HN: Pros and Cons of Developing a Desktop vs. a Web App?
Desktop: pros -> more productive, simpler, stabler APIs and frameworks, easier for « backend devs », more information density, better screen management (multi windows), more access to native devices and features, ... cons -> deployment / upgrade workflows, dependant on client configuration, usually less portable, easy to leak domain logic in frontend, harder to scale, ...

Web: pros -> portable, “lightweight” client dependencies (browser), mobile / tablets, good separation of backend and front-end logic, ... cons -> less productive (generally), require more infrastructure and Ops, harder to fit LOB-apps workflows and information density requirements, many choices to choose from, fast changing, ...

But this is becoming a relatively false dichotomie with web-based desktop apps (electron based or specialized like OpenFin in the banking world).

alexis2b··on Salesforce is buying Tableau for $15.7B
You might want to check Striim - it wraps kafka + streaming transformers with a scripting language, and a visual pipeline design tool. It then offers some really nice dashboards with a real-time “feel”. Not affiliated in any way but I took it for a spin and was happy to see how much could get done with it in just a few hours and without prior knowledge.

More like -100% (perfectly anti-correlated) to +100% (perfectly correlated) through 0% (perfectly decorrelated) and everything in between!
