CCs··on Comparing AWS Lambda ARM64 vs. x86_64 Performance Across Runtimes in Late 2025
It is a pain to make any new platform useful enough for large adoption. Apple made a lot of effort to get MacBook M1 useable, same for AWS with Graviton. Eventually it will be adopted for Linux laptops too, even without a specific vendor focusing on it, but it will take time.
CCs··on C++26: range support for std:optional
Scala has it like this since day one. Tried to convince D to adopt it, but was unsuccessful. Glad that C++ eventually got there…
CCs··on %CPU utilization is a lie
Uses stress-ng for benchmarking, even though the stress-ng documentation says it is not suitable for benchmarking. It was written to max out one component until it burns. Using a real app, like Memcached or Postgres would show more realistic numbers, closer to what people use in production. The difference is not major, 50% utilization is closer to 80% in real load, but it breaks down faster. Stress-ng is nicely linear until 100%, memcached will have a hockey stick curve at the end.
CCs··on Microsoft became incompetent in IT
LinkedIn (also MS) has the same problem.

Also: minimum age to sign up is 16. But you need to be 18 to verify your account. And if you’re locked out, you need to verify your account and log in to open a ticket saying that you can’t log in…

CCs··on Different Brain Regions Are Infected with Fungi in Alzheimer’s Disease
If it turns out to be the cause too (maybe similar to cervical cancer), it's a huge discovery.

Asimov's book on science history is an interesting read, full with similar discoveries that were ignored for many years.

CCs··on CBCrypt: Encrypt from the client rather than send passwords to servers
Data encryption on the client side is one of the 5 features. See https://github.com/rahvee/CBcrypt and the "Tech Details Video".

"Users are able to login to servers, and encrypt all their data, without ever exposing their password or encryption keys to the server."

"And if the user's data on the compromised server is encrypted using the user's keypair, then even the users' data is still protected."

CCs··on CBCrypt: Encrypt from the client rather than send passwords to servers
When you email a token, you're back to square 1 and will need 2 factor auth.

In addition the reset password is not possible when the data is encrypted on the client side. This is how TrueCrypt works - if you forget the password, all your data is lost.

CCs··on CBCrypt: Encrypt from the client rather than send passwords to servers
There's an issue with passwords/keys not sent to the server: what if the user forgets the password?

No "Forgot your password?" functionality available (reset token), since the server does not store password (hashed or otherwise).

CCs··on Ask HN: I'm going to have to lay people off, and want your advice
I'm saying that there are many options with non-obvious consequences, so don't try to wing it. Any mistake will cost you orders of magnitude more than a professional advice.

I like Manager-Tools because it is step-by-step and actionable. Does not say "think out of the box" (how?), it gives you exact words that have worked for 1000s of companies.

BTW, performance based layoff list might be a legal issue in some case, for example when the reason is workforce reduction. Without a good lawyer don't go there...

CCs··on Low-Power $5 FPGA Module
Combine it with C.H.I.P. [1] and you have a $14 supercomputer.

The generic CPU could download over the air update (WiFi) and reprogram, take care of user interface etc while the FPGA can do the low-power, high throughput tasks (voice processing, video, image etc).

CCs··on OpenSSL Security Advisory
GC is not an answer to everything; sometimes works, sometimes you need to shortcut it.

Many people work on manual memory management for a reason http://event.scaladays.org/scaladays-sanfran-2015#!#schedule...

Security is a practice, not a programming language. Anthem uses C# and they are hacked almost every year. https://www.anthemfacts.com/

CCs··on Ask HN: Who is hiring? (March 2015)
HealthExpense Inc | Sunnyvale, CA | Full Time: 9 developers

We're currently looking for 9 experienced software engineers for a full-time position in Sunnyvale, CA (Backend, Frontend, Payment Gw dev, DevOps, Data Scientist, QA).

Us: Health claim management and payment technology company. Our aim is to fully automate the patient-side of health payments. In production for 4 years, with paying customers ranging from small TPAs to the largest banks in US.

Our challenge: integrating data ingestion for 100s of sources into a single, normalized database which is correct and real-time. The core is a custom ETL engine with data cleaning and error detection customized for each pipe. Due to episodic nature of healthcare we're handling heavy loads in peak times, like creating over 10,000s of users within a few seconds.

Our stack is mainly Scala and C++14, micro services: http://stackshare.io/healthexpense/healthexpense

It's fast. Seems great for quick tasks, which is most of the time for me.
CCs··on Scala.js no longer experimental
There's a difference between a lightweight transpiler like JSX and a compiler.

ClojureScript is pretty lightweight, but GWT and Scala.js compile process is not an easy one. Even Bootstrap.js optimization with Google Closure Compiler is an uphill battle. Try it with --compilation_level ADVANCED_OPTIMIZATIONS

Sourcemap does not help much with compiler bugs or if the compiler people have different opinion from you on how something should be translated.

CCs··on Scala.js no longer experimental
I'm skeptical of any x-to-JS compiler as usually I end up debugging 2 different codes, where the second one is machine generated. After that you try to work around on the first to make the generated one do what you want.

On the other hand the Scala people know how to write compilers. We're live, in production, with Scala since 2011 and it's a joy: it actually delivers what's promised. Heard the same thing from Twitter, LinkedIn and Netflix too.

So maybe it worth a try; especially if it will integrate with ReactJs / React Native. Sounds like a match made in heaven.

CCs··on Bootstrap 3.3.0 and Bootstrap 4
Yes, many enterprise companies are behind, but not all.

We're enterprise and upgrading to 3.3 as we speak. We see a 4-8% of users coming in from older IE, mainly XP. We have customers in USA only.

Our public website: 3% IE7, 5.2% IE8

App: 1% IE7, 3.3% IE8
