Yet, such idealized fragment is never formalized in mathematics. I think this is akin to the idea in <a href="https://math.andrej.com/2016/08/06/hask-is-not-a-category/">https://math.andrej.com/2016/08/06/hask-is-not-a-category/</a><br/><br/>So, I feel trying to establish connections with coding-focused paper necessarily need to sacrifice formality in order to recover the idealized fragment the original author have in their mind, since again, the full semantics of Haskell is too gigantic, and clearly out of scope for most papers. 2025-08-26T14:13:01Z https://yabu.me/nevent1qqstapmlg90rjf52zy4mkk7pzxu2whmm0zvtjjjs0zkzj6njlyeng6gzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfac8smjnt We should make a new version of Lean using Bool instead of Prop, and call it Boolean. 2025-08-22T12:56:45Z https://yabu.me/nevent1qqsdz8tplxs69tgnvv0xm9s7t4uup9ats64m069t2lq4vv5xk29ddcszyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacktw3ef I think there needs to be a category of PL works named &#34;SMT and prayers&#34;. 2025-08-20T10:50:21Z https://yabu.me/nevent1qqsg6dkrht2swykmtfl94eg96l5xgdm7ejwe4fs9tay4mfujsl3ehmszyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacpfsy90 If all road leads to Rome, all road also leads to anywhere else with a road. 2025-08-15T08:37:24Z https://yabu.me/nevent1qqsv3x4ktautpne4pkck2jtghmes6twnndsuk5jy9su84gva9amnv5szyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacglml24 In reply to <a href='/nevent1qqsf7gu3m920hh7vr74ur36c589573n2ld8cpzhcmtdhg20j70rnvgckeagns'>nevent1q…agns</a><br/>_________________________<br/><br/>Indeed the weakest part of my papers are always my research. 2025-08-11T19:34:32Z https://yabu.me/nevent1qqsrercg5haj7ukfx3704rtpdm2hqaxcqyge98kfpw7xemcsr8pnlwgzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfact03cgf My research stands between theory and practice. <br/>That means I get to suck at both programming and math. 2025-07-26T07:31:44Z https://yabu.me/nevent1qqsxjwgp5n3hnjplhpp8x7668eeyrptef0eyy8g0tqkxzk3dv9cvuzszyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacmsdd9e Got some Prolog today with <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub1v6afl9hlcsdeqcw06j3lqtv48xjqpmfyp2nc5e6k829vlp5ekg3qjac7s4" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Zhixuan Yang</span> (<span class="italic">npub1v6a…c7s4</span>)</a></span><br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/915/303/746/939/356/original/67e2a2b705781acd.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/915/304/235/479/053/original/6f6430b46489571f.jpg"> <br/> 2025-07-25T18:33:07Z https://yabu.me/nevent1qqswd7jgp3s9vsd2q48pdf8j4tt3fv6da0znn4y4fl8dt6wuk9a33eqzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacxs68l5 Nowadays, the primary drive for my researches is to publish papers with puns in their titles. 2025-07-02T13:40:48Z https://yabu.me/nevent1qqsy068xdhm7022a5rek6nv4zd44vpj33pqzmgtnw6lkym0f9hssk5gzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfac565aky (• − •)<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/114/688/205/268/636/865/original/abee30ae3ae3bb9f.png"> <br/> 2025-06-15T16:00:04Z https://yabu.me/nevent1qqsvsdwegp07z6qu3yrj36kuwq8f845838p2q0vxcm8vf0hrkpm2fyczyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfactgfk4h Math is the only kind of magic where peeking behind the curtain only makes it more fun. 2025-06-14T11:35:55Z https://yabu.me/nevent1qqs9p7mut67ssmkdnz5k9hx8akh6jr0ulh3jhjmj0dngauw7z5thkeczyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfaceevley Showering is probably the most important invention for scientific advancement. 2025-06-09T15:00:27Z https://yabu.me/nevent1qqswkv0j7un9qcwpwvlpqhj5hrmtyhp40zxmt6d5zh76dgxpnaf4csszyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacm55n93 &#34;I am not perfect...

As I am planning on leaving the U.S. for my postdoc. I am making some sauces that will help my wife cook.<br/><br/>I was planning garlic sauce (for stir fry), spicy chicken stew base (烧鸡公底料, despite its name, can do almost all spicy stew, and even some stir fry), and chard chili sauce (go into cold dish and can be eaten straight with rice or noodles).<br/><br/>Now, in the light of my 5lb garlic purchase, I have garlic sauce, garlicky spicy stew, and garlic chard chili sauce. Fortunately, my wife really really likes garlic 🤪.<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/300/835/582/206/341/original/fbaeb850ff68eed7.jpg"> <br/> 2024-10-13T15:32:57Z https://yabu.me/nevent1qqswdqntudz6tk29enu4xmpdaswr3m60a48um65mtjr8tsuhr6sa4zqzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacnax5mp After having a laugh at <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub1f206cs6ga0ck6mag8f7qqem4xtnn4axy2w9apqd0l3ahvf4sphasywd5dd" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Dan Ports</span> (<span class="italic">npub1f20…d5dd</span>)</a></span> &#39;s 5lb of New Mexico pepper with my wife, I, in my infinite wisdom, brought 5lb of raw peeled garlic.<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/296/657/193/132/797/original/4520d0d711981dc8.jpg"> <br/> 2024-10-12T21:49:54Z https://yabu.me/nevent1qqs8mr3vsf6xcygu92dgfwynut4jgd6dzue9k5l057lfmw5e50tll5szyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfac5ln9jt In reply to <a href='/nevent1qqsqn9ewfcl9ha4u657n539swnszez8sz8u60vedalw40dw2gw7yv5grvwsy4'>nevent1q…wsy4</a><br/>_________________________<br/><br/>Pfff, almost forgot the most important one...<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/246/370/570/981/643/original/823cdaea57241039.jpg"> <br/> 2024-10-04T00:41:21Z https://yabu.me/nevent1qqsqn9ewfcl9ha4u657n539swnszez8sz8u60vedalw40dw2gw7yv5gzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfac7atyrx rate my setup<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/246/311/512/266/309/original/10e57e36dff08ddc.jpg"> <br/> 2024-10-04T00:26:21Z https://yabu.me/nevent1qqsf0ajsgkzenqczj8k3jp230tdnuq8c84dgcne6t7pa72808h4f58gzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfacecc5ps DO **MORE** NIGHTMARKET!<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/221/216/786/570/366/original/1fd06a24605fb26a.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/221/216/942/037/274/original/41b4fb4c8c4567ee.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/221/217/118/189/819/original/abf1020d43a2def5.jpg"> <br/> <img src="https://media.mathstodon.xyz/media_attachments/files/113/221/217/275/304/974/original/f68da4207c12cf23.jpg"> <br/> 2024-09-29T14:04:34Z https://yabu.me/nevent1qqsp2u3244qn9mwdmk9yhw46mef0sca3u0l32hfr5ntg533x74dpx5qzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfackhew03 I currently have a plain text single page website (<a href="https://czhang03.github.io/">https://czhang03.github.io/</a>). I used to enjoy the plain-text aesthetic, but recently I started to feel that the page is getting too cluttered and do not draw people in anymore.<br/><br/>Should I keep plain text, or do whatever hip CSS thing that people use? 2024-09-18T15:49:20Z https://yabu.me/nevent1qqsy625e0hagphgpljvtrumfkpqzjrjf9uzwyju6ssxhszuwpkvnyrqzyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfac06xss2 Not too bad for a initial sticker bomb<br/> <img src="https://media.mathstodon.xyz/media_attachments/files/112/963/233/651/720/286/original/4016ce578a9f8f6a.jpg"> <br/> 2024-08-15T00:35:55Z https://yabu.me/nevent1qqsxevnly5uyg7dzgeyuzxqyjjwn7y4uq2txsgsmjdr6ncnk6ruxeaczyrnp87xn7syj6wv72yjazuzt7t0lu6r0dwfpzmsey8nca2wvdxfaczklrdg Do I sticker bomb my laptop 2024-08-02T20:31:21Z
