(u)int8_t have the same problems, including aliasing because they are just alias of (unsigned) char. Sometimes it's nice to have modular arithmetic mod 256, or compact memory layout for eg. count sketches.

Depression can be seen as protection mechanism that reinforce rigid thought patterns in order to avoid runaway (psychosis, mania). So anything tiping the balance in the other direction allows to deprogram those behaviors. This is related to

Thank you for the clear explanation. Could this find applications in (realtime ?) acoustic room correction on embedded devices ?

Do you think it's planned to bring back noalias in rustc ? This, along with const generics and simd, would make rust the perfect language for me.

Yes, I'm aware of that. Sorry, bad wording. I choose btrfs because it's simpler to setup. It is also lighter on memory for uses on personal machines. I know ZFS can work with less memory but at a performance disadvantage.

Honestly not bad. About 7 years of use on personal machine, single volume. It simpler than ZFS and allows cheap incremental backups with send/receive. One year ago I built a RAID56 with 5 used 2TB drives from eBay. Risky move, but it w

I upgraded a free T410 with two X5675, 32GB ECC RAM, PCIe to NVMe adapter, a RAID array of 2TB drives and an USB3 controller. I's a quite capable machine. I needed it to learning about NUMA archs and test my software. However there is

Having a very large distributed surface area could be key to drive the peltier cells at low current and get back some efficiency. The thermal contact with the body also helps by reducing the temperature gradient against the charges flow.

In my field (bioinformatics), there is a trend of using a single hash function, an over-sized bloom filter which is then compressed with something like entropy optimal RRR[1] or RoaringBitmap bit vectors. The resulting bloom filter ends up

A good blog post about xor-shift-multiply reversible hash functions: https://nullprogram.com/blog/2018/07/31/ The inverse functions are easily found by computing the modular inverses of the odd multiplic

The mini/micro-brute by Arturia are the new cheap analog bass synths. They combine a minimal amount of monophonic signal nodes while providing quite a lot of possibilities. The Voltage Control IOs are a bridge to Modular Acquisition Sy

Paypal's post login page comes to mind. I want to see the dashboard after login, not a uninformative ad that probably took time and money to put there.

Sadly, 10 years later, they didn't respond to criticism about removing support for non-ext4-yet-xattr-enabled filesystems.

I think F# will be my next learning project. Still keeping an eye on Idris, though.

I will keep my dual X5690 machine for few more years I guess. The increase IPC of modern CPU is only 33% compared to theses old Xeons. Although, power consumption is another factor to consider...

You're right. The main selling point of both turbines is the axial flow: the velocity differences between the water and the blades are the same on every sides of the turbine. The shear forces are low enough to let wildlife pass through

Random projections methods are cheaper alternatives to SVD. For example you can bin contexts with a hash function and count collocations between word and binned contexts the same way this article does. Then apply weighting and SVD if you re
