My static file HTTP server called "filed" [0] will satisfy a request in as few as 1 system call (no memcpy involved -- the kernel reads the file and sends the buffer to the NIC), by using sendfile(2). Most other webservers do a b

On Windows I mount it as the "A:" drive. It works but the port is not yet released.

AppFS [0] solves this by getting rid of the install step, which prevents many problems. [0] https://AppFS.net/ Disclaimers: I work for AWS, but not on the AWS CLI; AppFS is my own personal project

We were a relatively small cloud provider, but all disks were encrypted so at least we wouldn't leak someone's data if we had to replace a disk.

It was all made out of parts with standardized interfaces, so components could be consumer equipment. I also used the same software on my laptop to encrypt it. It's nothing fancy, just using the dm-crypt kernel module and any kind of

When I ran a cloud provider, we used a hardware security module on storage systems which had public/private key pair which could be used to decrypt the header on the disk which contained a copy of the symmetric cipher key. Each header

Email is a delay/disruption tolerant network, and each hop in the network has a positive acknowledgment that the message has been committed to stable storage (a high bar). If the final destination rejects the message a delivery failur

I have not used this (yet), but there are a lot of problems with Home Assistant, with the main advantage being that it has all the integrations already written and it works for most things almost all the time. Issues with Home Assistant as

As an alternative, one can also use User Mode Linux (UML) to implement a pretty fancy chroot (and fakeroot). It can do a few things userns can't, like load kernel modules. I've had to use this to deal with bugs in BtrFS before.

I don't buy it -- I've held clearances from that required a NAC to ones that required an SSBI, and got my first US National Security clearance when I was 16 and continuously held a clearance for about 20 years, as both a federal c

The question I have is that if Microsoft really thinks #1 is true and the way, why didn't they train Copilot on Microsoft's code (in addition to other people's code on GitHub.com) ?

It didn't sound like he attempted or succeeded in any sort of violent uprising against authority, despite his violence against the door. It sounds like he was attempting to comply with authority, perhaps in violation of some rules, or

by rkeene2 5y ago
I think that's my question regarding this whole thing: If it's so fair use, why not train it on all Microsoft code, regardless of license (in addition to GitHub.com) ? Would Microsoft employees be fine with Copilot re-creating &q

I've attempted to convince maintainers in the past to not do user-hostile things [0]. They seem to think they are entitled to a record of how I use their software on my own systems. It's not clear to me why they would think this,

This is the converse of Debian/kFreeBSD ! So if you find it interesting you might be interested in Debian/kFreeBSD as well.

This is done by some cloud software (e.g., OpenNebula). The downside is that modifying the metadata is now difficult since block devices being hot-plugged can cause issues if in use.
259.
by rkeene2 5y ago
OpenNebula solves this by attaching an ISO image with credentials and metadata to the CD-ROM virtual device, so only root can get the credentials to make calls and also the metadata is there.

Hmm, building UML from source is really easy. Here [0] is my process for doing it, as a Makefile. The actual compile step is just one line (line 32): $(MAKE) -C linux-$(KERNEL_VERSION) ARCH=um linux The rest of it sets up the con

I wrote "hashcache" [0] [1] for this for my Linux distribution (which is the build from source variety) to avoid issues with upstream going away, or worse changing the contents of a file. Many different caches can be used, in case

Do you believe someone who hasn't worked with the candidate in years is a useful reference for the candidate today ?
266.
by rkeene2 5y ago
If I'm interviewing a candidate, they likely still work with their soon-to-be-former boss, who likely still works at the same company the candidate is leaving. This is the most common case, by far. Are you suggesting going further back

by rkeene2 5y ago
The case where you are able to speak to the candidate's boss because they have also left is incredibly niche.

by rkeene2 5y ago
The company that the candidate previously worked for is typically not permitted to say anything about the candidate without prior authorization. Your proposed solution is not workable. I've previously hired contractors with minimal in

The double hash ones were meant to indicate that the channel wasn't "run" by anyone officially affiliated with the free software with that name. This isn't always consistent since there's no mechanism to determine

I've been thinking about a good way to explain this for a couple of days I think the best way is convert the ASN.1 to some psuedo-typed-JSON. For an X.509v3 public key, the ASN.1 would look like this in JSON-with-types: [
