ChatGPT and other transformer-based models like Dall-E are technologically very impressive. They do things that seemed totally impossible just a few years ago. However, they are not really generally intelligent, and there are innumerable problems with how they work, what they do, what people think they do, ethics, and legal and licensing issues. This is my third post about ChatGPT, where I present my critique of and reflections on the technology. The previous posts were about ChatGPT and Simics and Coding using ChatGPT.Continue reading “ChatGPT and Critique”
I finally got updated to Windows 11 on my work machine, and suddenly I have to figure out how to use Windows 11 for real work. The redesigned start menu is terribly bad compared to the Windows 10 variant. What is nice though is the new Terminal app, along with the quite pleasing Cascadia font. However, I found the default size of Cascadia to be a tad big. Which lead to the question: “just how on earth are you supposed to control the font on this thing?” The font adjustment is probably the least logical I have ever found, and without some help from the Internet I would never have figured out. So here is how you do it.Continue reading “Setting the Font in Windows 11 “Terminal””
During 2020 and 2021, Intel switched from using Microsoft Skype for Business (also known as Lync) to Microsoft Teams as the primary internal calling, chatting, and conferencing tool. While (finally) Teams has turned into quite a decent communications tool, the transition started a bit too early from a feature completeness perspective. Microsoft in essence gave us an enterprise Minimum Viable Product (MVP). Not a proper Replacement Product (RP). Teams left out many rather important and useful features, degrading the user experience and value, and making my life harder. I don’t think that was particularly well handled. I can understand it as a product manager, but as a user, I don’t like it all.Continue reading “Minimum Viable (Replacement) Product – The Teams Example”
I recently stumbled on a blog post called Building Faster AMD64 Memset Routines, written by Joe Bialek of the Microsoft Security Response Center (MSRC). The blog describes his efforts to improve the performance of the Windows kernel memset() function, across all sizes of memory to set. The reported optimizations are quite fascinating, and could be summed by avoiding branches even at the cost of doing redundant stores. Basically, stores are free while branches are expensive.Continue reading “Microsoft Windows memset Optimization – Stores are Free”
I just started using Office 365 at work, and almost immediately I hit a hilariously bad problem in the core simple “import CSV” functionality. Basically, the Excel 2016 that I got (it is 2016, not the latest 365 that my home machine all use) does not understand Windows line endings or decimal numbers.Continue reading “Excel 2016 & CSV Import – Hilariously Broken”
Last week was spent at the Design Automation Conference (DAC) in Las Vegas. I had a presentation and poster in the Designer/IP track about Clouds, Containers, and Virtual Platforms , and worked in the Intel Simulation Solutions booth at the show floor. The DAC was good as always, meeting many old friends in the industry as well as checking out the latest trends in EDA (hint: same trends as everywhere else). One particularly nice surprise was a book (the printed type, not the Vegas “book” that means something else entirely).Continue reading “DAC 2019 – Cloud, a Book, an Award, and More”
For some reason, Microsoft has decided to hide some decidedly useful features in Windows 10 explorer behind the non-intuitive and rather unknown “shift-key + right-click” combination.Continue reading “Off-Topic: Windows Explorer Tip: Shift Right-Click”
There are some things in computing that seem “obviously” true and that “clearly” make it “impossible” to do some things. One example of this is the idea that you cannot go backwards in time from the current state of a program or computer system and recover previous state by just reversing the semantics of the instructions in the program. In particular, that you cannot take a core dump from a failed system and reverse-execute back from it – how could you? In order to do reverse debugging and reverse execution, you “have to” record the state at the first point in time that you want to be able to go back to, and then record all changes to the state. Turns out I was wrong, as shown by a recent Usenix OSDI paper.Continue reading “Microsoft REPT: You CAN Reverse from a Core Dump!”
In a previous Intel blog post “Question: Does Software Actually Use New Instruction Sets?” I looked at the kinds of instructions used by few different Linux setups, and how each setup was affected by changing the type of the processor it was running on (comparing Nehalem to Skylake). As a follow-up to that post, I have now done the same for Microsoft* Windows* 10. In the blog post, I take a look at how Windows 10 behaves across processor generations, and how its behavior compares to Ubuntu* 16 (they are actually pretty similar in philosophy).
Skype for Business is an interesting beast. It is a nice little program for internal collaboration, but some of its behaviors are just super-annoying. One my pet peeves is the fact that when you get into a meeting with screen sharing you have a bunch of big heads covering up a sometimes significant chunk of the materials being presented. I finally figured out how to get rid of them. It comes down to the view mode. This little icon in the toolbar:
Now that Windows 10 has been officially out for a while, I decided to give it a try on one of my home machines. I expect that all my Windows 8.1 machines will be updated eventually – it is a free update, after all, and supposedly things should work just as well as in Windows 8.1. Just with a different user interface. Windows 10 is indeed different from Windows 8.1 in fairly significant ways, and it really feels like what would have come after Windows 7 if Windows 8 hadn’t come between. I can see why many or even most people see this as the better upgrade path, even if I lament some of the changes made.
At the ISCA 2014 conference (the biggest event in computer architecture research), a group of researchers from Microsoft Research presented a paper on their Catapult system. The full title of the paper is “A Reconfigurable Fabric for Accelerating Large-Scale Datacenter Services“, and it is about using FPGAs to accelerate search engine queries at datacenter scale. It has 23 authors, which is probably the most I have ever seen on an interesting paper. There are many things to be learnt from and discussed about this paper, and here are my thoughts on it.
Apple just released their new iPhone 5s, where the biggest news is really the 64-bit processor core inside the new A7 SoC. Sixty four bits in a phone is a first, and it immediately raises the old question of just what 64 bits gives you. We saw this when AMD launched the Opteron and 64-bit x86 PC computing back in the early 2000’s, and in a less public market the same question was asked as 64-bit MIPS took huge chunks out of the networking processor market in the mid-2000s. It was never questioned in servers, however.
It used to be that Microsoft was the big, boring, evil company that nobody felt was very inspiring. Today, with competition from Google and Apple as well as a strong internal research department, Microsoft feels very different. There are really interesting and innovative ideas and paper coming out of Microsoft today. It seems that their investments in research and software engineering are generating very sophisticated software tools (and good software products).
I have recently seen a number of examples of what Microsoft does with the user feedback data they collect from their massive installed base. I am not talking about Google-style personal information collection, but rather anonymous collection of user interface and error data in a way that is more designed to built better products than targeting ads.
There seems to be no shortage of bugs that “should have been obvious” and subject to the “how can you not check that your own products work together” phenomenon. Just the other day, I stumbled on another one. This time, it was the Microsoft set of applications and operating systems that do not quite work together the way you would expect them to.
