The Highlander Principle has three important corollaries:<br/><br/>- If you insist on using containers, use them *only* for service configuration and isolation, not for package management.<br/><br/>- An OS that manages its &#34;core&#34; separately from &#34;applications&#34; or &#34;ports&#34; or whatever is misdesigned.<br/><br/>- If you need software that hasn&#39;t been packaged in the form your OS-level package manager wants, you need to package it in that form yourself. 2025-08-29T17:47:55Z https://yabu.me/nevent1qqsfpu9w2sgjqqh26thl27vry4pgc30zdqgv8sudcw5mu354tpgwxmczypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgxygpg7 In reply to <a href='/nevent1qqsqg4awhztvy2wpd8k8m6gpgur9ln4y95273lxhsqsu2u9t74h8eqgev53hc'>nevent1q…53hc</a><br/>_________________________<br/><br/>13. I call this the Highlander Principle of Software Package Management: There should be *one* package manager on your computer, and it should manage *all* of the installed software on your computer.<br/><br/>This is, IMO, true for all computers no matter what, but it is especially important for servers. If you have to run more than two or three commands to get *everything* updated with the latest security patches, that&#39;s too much work and you&#39;re going to fall behind on it. 2025-08-29T17:46:21Z https://yabu.me/nevent1qqsqg4awhztvy2wpd8k8m6gpgur9ln4y95273lxhsqsu2u9t74h8eqgzypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jg8sdhlg In reply to <a href='/nevent1qqs98zzkhtzyazv566mvsynxgfc89fvflkln0v3wqnw42t95q8el5cctqwcnp'>nevent1q…wcnp</a><br/>_________________________<br/><br/>12. Containers are massively overrated. You can get 90% of the same inter-service isolation, for less than half as much effort, with traditional Unix accounts. If you&#39;re willing to put up with systemd, it can impose restrictions on daemons that, as far as I can tell, are every bit as strong as what containers do. 2025-08-29T17:36:50Z https://yabu.me/nevent1qqs98zzkhtzyazv566mvsynxgfc89fvflkln0v3wqnw42t95q8el5cczypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgcu6596 In reply to <a href='/nevent1qqsddvkka5lzlmrlzhddpydpp37kwunqex9ctnzcwhuhtzyncz9lz8g3edn40'>nevent1q…dn40</a><br/>_________________________<br/><br/>11.

Closely related to 7: The sheer complexity of Linux&#39;s various &#34;mandatory access control&#34; modules - SELinux, AppArmor, etc - leads me to believe that most people are better off not only not using them, but configuring them out of the kernel.<br/><br/>I don&#39;t know what the *BSD equivalents are, or if they even have any, but if they do I suspect they&#39;re equally complex, because the people who *want* this feature have complex needs. 2025-08-29T17:23:47Z https://yabu.me/nevent1qqszd2w698er5hsdhkq088savpt0e25acqcq68tyy8xxan5a2g0rpgczypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgh4swwl In reply to <a href='/nevent1qqsqq3jrv0w5p7ej43vnqds05933q060mu449rcr2njpus4ve9vw00qreq3e0'>nevent1q…q3e0</a><br/>_________________________<br/><br/>7. The biggest single thing you can do to protect yourself against privilege escalation *into the kernel* is to use a monolithic kernel.

In particular, I wouldn&#39;t bother with dropping instead of rejecting SYNs to closed ports, and I&#39;m dubious about firewalling by port number. (About the only thing that&#39;s good for, IMO, is putting an extra speed bump in front of an adversary who already has remote execution and wants to persist it.) 2025-08-29T17:14:41Z https://yabu.me/nevent1qqs0rd3hruhnjrtmrqu2cx3gsdeyvq976p07868gtde5skem9xagwlqzypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jghrdmey In reply to <a href='/nevent1qqsd436fvnrjhmfw4nlvud0qd8nnu67ee8sxrmdc4zugazq3r2ngqncr2e3y6'>nevent1q…e3y6</a><br/>_________________________<br/><br/>5.

Reducibility of fractions represents something observable and intuitive in everyday life (think about cutting up pizza). It doesn&#39;t involve infinity at all. It only seems like a related thing to &#34;0.999... = 1.000...&#34; if you already know how to think like a mathematician. 2025-08-05T15:39:31Z https://yabu.me/nevent1qqsx5efk37zlrhtaq8lhdsm7y0qhgf0c6jfletmml2pk2gwc5ccd54szypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgkl2ckh Had a nightmare that someone posted one of my unfinished coding projects to HN and I got a pile of hate mail 2025-08-01T11:59:10Z https://yabu.me/nevent1qqsvy4lnflugx4f0s05pzhlu5h5vfwdtawra50ell949vhremlgu32gzypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgmx3hy3 I&#39;m declaring today to be No Context Research Visualization Thursday.<br/><br/>Post a data visualization from your research, whatever it is, with no explanation or context.<br/><br/>Here&#39;s mine:<br/><br/>#NoContextResearchVisualizationThursday<br/>#NoContextForYou<br/> <img src="https://cdn.masto.host/mastohackerstown/media_attachments/files/114/949/118/526/178/870/original/67e9ed8c43614137.png"> <br/> 2025-07-31T17:56:41Z https://yabu.me/nevent1qqsxr8g3pes4z09mmlxctrd9qruhyrmgrx448qs587q885gra7txn0gzypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jgqc3wy8 Suppose you encountered a piece of software named &#34;service-domowik&#34;, what would you think it did?<br/><br/>If you don&#39;t know what &#34;domowik&#34; means, you may choose to answer either before or after looking it up. 2025-07-19T21:12:05Z https://yabu.me/nevent1qqszs8rsxmvvfwc88jfe2rah7uax8zfh32hnqqqht6m05nqw7mj6rqqzypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jg5j8gs6 In reply to <a href='/nevent1qqstua2m6m3ukwr2y2dlu4r202eczczjckl5xahhvted03gp9872h4c4zcfwv'>nevent1q…cfwv</a><br/>_________________________<br/><br/>I think <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub1hv5x9ks4guwsvp4e2zg50qsu9kqsnjgsygngr7ams9j2j76jlw9s6zxq0v" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Sumana Harihareswara</span> (<span class="italic">npub1hv5…xq0v</span>)</a></span> and <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub18c8uala4cj7vw3sftkwq5e2hepsyavvch4s4qrz55zwpe3pawusq4mgrwj" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Leonard Richardson</span> (<span class="italic">npub18c8…grwj</span>)</a></span> may have some ideas<br/><br/>Based on last week&#39;s experience with my sister&#39;s 5-year-old I&#39;d just mention that being allowed to run around in Central Park for hours might well be a winner. 2025-06-30T03:23:40Z https://yabu.me/nevent1qqsz8jahp89g5x5rlt4k4y2xqum6wlsrjej7lrcmu4u48uu6c5zzrhszypljna5wsp3f2w0lzng9p2nhlll449csccysm9mj3nqkvx806c2jghuhf97 The album I&#39;m listening to right now holds together way better, musically, if you play the tracks in the order they appear on the CD.<br/><br/>I discovered this by accident, having mislabeled the files, but it makes me wonder: &#34;shuffle play&#34; has been a feature for a long time.
