How do register windows differ from register renaming? https://en.m.wikipedia.org/wiki/Register_renaming
chowyuncat··on Bentō is an alive, unstable Japanese noise box by Giorgio Sancristoforo
It’s a noise generator. It’s funky and having a noisy interface adds to the appeal for me.
chowyuncat··on Remove the Notch
There is a third option: https://twitter.com/marcedwards/status/1450798991633833992
chowyuncat··on Show HN: Coding Font – A game to find your favorite coding font
This worked well on iOS Safari. Nice job! At the end I wanted to know the distribution of other users’ preferences.
chowyuncat··on Woman may have tried to sell Pelosi computer device to Russians, FBI says
Imagine the use of the word deplorable to describe certain people. This would be then used in an election campaign to favor an opposition candidate who would vote against Russian sanctions.
chowyuncat··on Evolving Container Security with Linux User Namespaces
It’s an information leak. Who knows what attackers can learn about the host via this channel. Why leak it unless you have to?
chowyuncat··on As Joe Rogan’s platform grows, so does the media and liberal backlash – why?
Alex Jones is a terrible human being. Rogan is another con man in Jones’ vein, and the fact that they’re friends should tell you that Rogan isn’t a good person, either. Nobody who chooses to amplify Jones can be considered a decent person.
chowyuncat··on Judge rules Seattle media companies must hand over protest images to police
Because the police have committed crime on video and not been prosecuted.
chowyuncat··on Why Skylake CPUs Are Sometimes 50% Slower (2018)
This is funnily related to the Win9x crash on fast CPUs.
chowyuncat··on The radix 2^51 trick (2017)
ED-209 was a killer class.
chowyuncat··on FCC approves T-Mobile and Sprint merger
That first graph has no meaning without some granularity. Plot success of school against actual funding. It could easily represent 9 schools with 1000 per student and one school with 9000000 per student and result in 90 percent failing schools.
chowyuncat··on 27 Hours as a Cab-Dodging, Tip-Chasing Food App Deliveryman
Unbelievable exploitative. Thanks for researching. I came here while reading the print edition hoping for a clarification.
chowyuncat··on In Hong Kong, one protester pulls off his mask and defines a movement
Jail, torture, and death followed by organ extraction.
chowyuncat··on The infrastructural humiliation of America
Gettysburg wins if you use this metric.
chowyuncat··on Best Display for Programming? (2017)
I think this falls apart on Mojave. I use 27" Cinema Displays that are noticeably less readable even with the various font smoothing settings. Perhaps I haven't found the right combination.
chowyuncat··on Ask HN: Why and how is Gartner Inc. still relevant?
I’ve heard it claimed that those in leadership use it to justify the purchase of a product. Sort of a “nobody ever got fired for buying what Gartner recommended.”
chowyuncat··on Why Did Facebook Fire Palmer Luckey? It Had Something to Do With Trump
Do you believe the current administration is also deserving of incarneration?
chowyuncat··on Apple's T2 Will Block Linux from Booting
Some Linux bootloaders such as RHEL's are signed by Microsoft to avoid having to manually enter a new trusted cert into the EFI.
chowyuncat··on Shrinking Machine Learning Models for Offline Use
For a security product deployment of the model over the internet is a significant cost. Hundreds of thousands of machines in an enterprise may need to be updated at once. These machines may not have an easy way to accelerate the evaluation of the model, either, making feature reduction important for CPU work as well.
chowyuncat··on Dazzling NASA 4K moon video crackles with craters
If you like this, I'd recommend following the JAXA YouTube channel. Beautiful HD moon footage: https://www.youtube.com/watch?v=L0GX-nGSXMA https://www.youtube.com/watch?v=H1KWtG66lEQ
chowyuncat··on Why It’s So Hard to Actually Work in Shared Offices
Complex kernel code updated monthly via the cloud to millions of Windows, Linux, and Mac boxes?
chowyuncat··on Escaping Docker container using waitid() – CVE-2017-5123
The former part was exactly what was done.
chowyuncat··on Escaping Docker container using waitid() – CVE-2017-5123
The exploit overwrites kernel memory credentials of a task structure. That structure is the lynchpin of kernel security, including SELinux.
chowyuncat··on Escaping Docker container using waitid() – CVE-2017-5123
Think of it this way: what if the author had titled it "Escaping Ubuntu containers" ?
chowyuncat··on Escaping Docker container using waitid() – CVE-2017-5123
The kernel style guide mandates no curly brackets in this case.

chowyuncat··on A Message to Our Customers about iPhone Batteries and Performance
The consumer-friendly response is a large notification that explains that the battery should be replaced while also downclocking.
chowyuncat··on A Message to Our Customers about iPhone Batteries and Performance
No, the consumer doesn't have enough information in this case. They are more than likely going to buy a new phone rather than a new battery.
chowyuncat··on High Sierra macOS freezing and stops
It still has the most stable implementation for Linux development when compared to VirtualBox or Parallels. Docker for Mac is great for user space dev, but I haven’t figured out how to kernel debug yet.

Two recent showstoppers, when I tried to switch from Fusion:

The shared folder driver for VB will panic a Linux guest if a shared folder is accessed from a multithreaded compilation.

The shared folder driver for Parallels will panic a Linux guest if you load a kernel module from a shared folder.

chowyuncat··on A preview of the U.S. without pensions
How were they able to catch up in just three years?
chowyuncat··on Kernel debugging for newbies
Network debugging over VMWare to a 2.6 kernel (e.g. RHEL 6) will not work much of the time; a virtual serial port must be used instead.
