With the current model kernel level access is required. Real security products have to be able to operate above userland. Ideally in the future there can be a layer in between userland and kernel for this sort of thing. Maybe we use some

Oh you're totally right about the driver APIs. A fair amount has been added, but that stuff gets a new export to avoid breaking anything. For example, there's a dozen different `ExAllocate`s now. I wouldn't call myself a d

I'm talking about the kernel space itself, not the APIs exposed to userland to interface with the kernel from your application. Internal APIs and behaviors are mostly identical over the past ~20 years, and any changes are usually move

A fair amount has been changed or added, I'd say. I recommend the Windows Internals book if you're interested in learning about the Windows kernel. The 7th edition just came out.

Until I started working at a SaaS company shipping to Windows enterprise customers I thought PowerShell wasn't used by anyone. Now I see it all the time. It's not fantastic, but if you're in the Windows world it beats writi

I haven't profiled our Windows kernel driver across different kernel versions (maybe I should!) but I'd like to offer this perspective: the kernel is incredibly stable from my driver development point of view. The biggest reason

I'm not sure emacs modes offer this level of extensibility, but I'll check them out.

As a baseline solution "language" could be substituted for "unicode range". Re "use a better font": fonts are something I enjoy and I try new ones frequently.

Alignment could definitely be a challenge. Perhaps a better personal solution would be to write something to combine two fonts in a way that also solves alignment. Not a very "accessible" solution but definitely easier.

This is applying a font for an entire window/frame/buffer, right? Not applying two fonts for different characters within the same buffer.

pannen's commentated videos are always a treat. He started uploading again this year after a long hiatus (that started after this video) and I can't wait for more. If you're interested in Super Mario 64 speedruns, the video[

Linux desktop users specifically don't have to worry about malware or ransomware until it gets significant usage. Just like people used to say Macs don't get viruses until enough people used them. Last time I checked (could be

The difference might be that workers have an interest in maintaining the business so they still have well paid jobs while CEOs do not necessarily have an interest in unions' well-being.

Cool! I'm relatively young, so the only interaction I've ever had with a rotary phone was my dad finding one in a box at my grandparents' house. Still, this seems like fun. Cool that you can communicate with the cell modem

Third parties are perfectly capable of making replacement parts that match the OEM parts in functionality and quality. This has no effect on integration. The other parts of the phone don't care who manufactured the part, unless they

In the Super Smash Bros. Melee competitive scene we still use CRTs for in-person tournaments because of the input lag on LCDs. Most original hardware available to play the game doesn't have a digital display output unless you have an

The T runs mostly on a separate rail, but there are a number of places in city limits where it runs with cars on the street. Check out Arlington Avenue in Allentown (the Pittsburgh neighborhood, not the city).

If I understand correctly, this is just a kernel-mode snippit to copy the System process token to your target process. It assumes you've already found a vulnerable driver to execute code in the kernel. If you can execute code in the

I wish nobody did. I work for a security company writing Windows kernel drivers and I still have to support Windows 7 / Server 2008 R2. There's been talk of porting to Vista!

Malware / ransomware / security products have been doing this for many years, especially to Windows modules like kernel32.dll and ntdll.dll.

Sounds like this idea is limited to the curl tool and wouldn't add anything to libcurl, which is great. I'd prefer libcurl leaving JSON to other libraries. I use bash variables inside JSON with curl all the time, which leads to s

If the purpose of defer is to replace the `goto single_exit`, I think the value captures are unnecessary. Any single_exit I've implemented uses the value at the time of function exit, so that I can realloc in the middle of the functio

20 year old cars hit the sweespot for me. They're repairable and reliable (given a reputable model), and they're new enough to have airbags. I hope electric cars take advantage of their simplicity and become very repairable, but I
