About matt_heimer

My day-to-day job deals with Java (which I actually like) and web development. I run an Operating System Development website (osdev.org) as a hobby.

    Ozempic == GLP-1 which the first visible paragraph is discussing.

    Not exactly the same but I'm building a NAS box with old parts. Most of my spare RAM sticks are laptop DDR4 SODIMMs. There are SODIMM -> desktop DIMM adapters... it did not go well…

    I'd have a better portfolio right now if I invested in RAM instead of equities.

    That's the traffic after rate limiting controls and bot fight mode. It's 3-4 million requests per day without bot fight mode and just rate limits. And as I said it's not a smooth d…

    It might depend on the tech stack. I run a small niche website but it has PHP and a database (MediaWiki/PHPBB) and without Cloudflare I'd estimate I'd need to spend several hundred…

    Sure, depends on how accessibly to people you want it to be. Most legit search engines are going to honor robots.txt and you can disallow access. Next level would be using somethin…

    What is the positioning for this and how does it work? A comparison to SBE might be nice. I understand the issue about using Layout and MemorySegment being verbose but the reason I…

    It's perfect for toddlers (I mean that in a good way), it's the infinite answer to the infinite "What's that?" series of questions they can generate. Make everything a hyperlink an…

    I guess that's true but I find Google's models better than their public tooling. The Pro subscription includes "Gemini Code Assist and Gemini CLI" but the Gemini Code Assist plugin…

    I was a bit worried when I saw the title of the article because I have one of these accounts but geez he made some bad choices. Deleting all phone numbers and the recovery and swap…

    That's only good for the web based UI. If you want Gemini API access which is what this article is about then you must go the AIStudio route and pricing is API usage based. It does…

    If you use Google's tooling but not if you need API access. API access is not in the subscriptions and uses token based pricing. For development I find that the Gemini IDE plugins …

    I shipped with signature verification to the buyers address. The buyer claimed they didn't receive the item and eBay still sided with them and refunded their money. I will never se…

    isn't an issue ONLY with macbook keyboards. It is absolutely an issue that shouldn't exist.

    Funny, I just bought Start11 from Stardock for side taskbar placement. It was the oddest choice to remove that feature. On an ultrawide monitor it just makes so much sense.

    Yes, it's not surprising that warnings and complexity increased at a higher rate when paired with increased velocity. Increased velocity == increased lines of code. Does the study …

    Software HFT? I see people call Python code HFT sometimes so I understand what you mean. It's more in-line with low latency trading than today's true HFT. I don't work for a firm s…

    Probably the same thing that makes most developers choice a language for a project, it's the language they know best. It wasn't a matter of choosing Java for HFT, it was a matter o…

    You program differently for this niche in any language. The hot path (number crunching) thread doesn't share objects with gateway (IO) threads. Passing data between them is off hea…

    You can achieve optimized C/C++ speeds, you just can't program the same way you always have. Step 1, switch your data layout from Array of Structures to Structure of Arrays. Step 2…

    I've been using several. LM Studio and any of the open weight models that can fit my GPU's RAM (24GB) are not great in this area. The Claude models are slightly better but not wort…

    I'm building a Java HFT engine and the amount of things AI gets wrong is eye opening. If I didn't benchmark everything I'd end up with much less optimized solution. Examples: AI re…

    Except in another linked page https://www.notebookcheck.net/M5-Max-with-inconsistent-perfo... they also mention a thermal issue. Either way, this article is almost entirely about a…

    If I remember correctly a previous MacBook air could have improved thermal dissipation by adding some thermal tape and turning the case into a heatsink.
