  16. &lt;p&gt;I just want to say something about new macs. They are rubish. I never had freezes and reboots with old macs.&lt;/p&gt;
  17. &lt;p&gt;I&#x27;ve been running a M2 air for more than one year and it has frozen and rebooted on me several times. If I push it too hard it panics and reboots.&lt;/p&gt;
  18. &lt;p&gt;Early on it was Wifi connection that wasn&#x27;t stable and forced me to disable &quot;Continuity&quot; with my iPad, to try to keep it running longer than 5 minutes.&lt;/p&gt;
  19. &lt;p&gt;Now with AI trying to run the smallest Ollama models is a challenge. It might just poop on you and reboot. Twice in the last hour. ME NOT HAPPY.&lt;/p&gt;
  20. &lt;p&gt;Sorry, just wanted to get this out of my chest&lt;/p&gt;
  21. &lt;p&gt;PS - asking the wife for her Dell so I can run the models.&lt;/p&gt;

  31. &lt;h2 id=&quot;added-an-rss-feed-to-sixhatnet&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#added-an-rss-feed-to-sixhatnet&quot;&gt;Added an RSS feed to sixhat.net&lt;/a&gt;&lt;/h2&gt;
  32. &lt;p&gt;I&#x27;m a big fan of serving content via RSS feed.
  33. But &lt;a href=&quot;https://rust-lang.github.io/mdBook/&quot;&gt;MdBook&lt;/a&gt; doesn&#x27;t provide RSS.
  34. It is mainly targeting the production of books.&lt;/p&gt;
  35. &lt;p&gt;I decided to script my blog&#x27;s RSS and with a bit of &lt;a href=&quot;https://www.python.org/&quot;&gt;python&lt;/a&gt; plus a bit of &lt;a href=&quot;https://beautiful-soup-4.readthedocs.io/en/latest/&quot;&gt;BeautifulSoup&lt;/a&gt; I now have a &lt;a href=&quot;rss.xml&quot;&gt;RSS feed&lt;/a&gt;.
  36. It is basically a RSS 2.0 spec and &lt;a href=&quot;https://www.rssboard.org/rss-validator/check.cgi?url=https%3A%2F%2Fwww.sixhat.net%2Frss.xml&quot;&gt;passes validation&lt;/a&gt;.&lt;/p&gt;
  37. &lt;p&gt;Some things might brake as the process is still not fully tested and robust.
  38. It doesn&#x27;t support enclosures for now (no podcasts or rich media in the pipe).
  39. It doesn&#x27;t have advanced features, has basic html in the content (escaped, not that CTDATA stuff).
  40. It is simple, as &lt;a href=&quot;https://en.wikipedia.org/wiki/RSS&quot;&gt;RSS&lt;/a&gt; should be (Real Simple Syndication).&lt;/p&gt;
  41. &lt;p&gt;Ah, if you need an &lt;a href=&quot;https://github.com/ckampfe/russ&quot;&gt;RSS reader&lt;/a&gt;, try RUSS.
  42. I&#x27;m loving it.&lt;/p&gt;

  105. &lt;/code&gt;&lt;/pre&gt;
  106. &lt;p&gt;One of the best coding challenges out there is &lt;a href=&quot;https://adventofcode.com/&quot;&gt;Advent of Code&lt;/a&gt;.
  107. It is a really fun and engaging way to learn a new language or to revisit something that you&#x27;ve been away for so long.
  108. In my case it was python.
  109. Python was the language I wrote my PdD in, but at the time I was using version 2.7.
  110. I barely touched python since.
  111. This year I decided to do &lt;strong&gt;AoC&lt;/strong&gt; with python 3.11 and wow, what a difference.
  112. I love this language.
  113. It is so pleasurable to work with.&lt;/p&gt;
  114. &lt;p&gt;I&#x27;m keeping this entry about the things I&#x27;m (re)learning&lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#day&quot;&gt;1&lt;/a&gt;&lt;/sup&gt;.
  115. Thing that either I didn&#x27;t use before or were still absent in 2.7 days.
  116. These things emerged as I progressed through the challenges and compare my code with others&lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#github&quot;&gt;2&lt;/a&gt;&lt;/sup&gt;.&lt;/p&gt;
  117. &lt;p&gt;Around day 18—20 of AoC I &lt;em&gt;stopped&lt;/em&gt; participating.
  118. Challenges became more specific about using certain advanced algorithm or data structure and became harder.
  119. As a consequence the time devoted to solving increased.
  120. The issue is that I don&#x27;t have that time, but in any case I&#x27;m still going through solutions.
  121. The objective is to learn and recall the most of python possible.
  122. And in the end it is all time management.&lt;/p&gt;
  123. &lt;h3 id=&quot;tips-learnt&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#tips-learnt&quot;&gt;Tips learnt&lt;/a&gt;&lt;/h3&gt;
  124. &lt;ul&gt;
  125. &lt;li&gt;&lt;code&gt;enumerate&lt;/code&gt; is a very useful command.&lt;/li&gt;
  126. &lt;li&gt;&lt;code&gt;zip&lt;/code&gt; is also very useful.&lt;/li&gt;
  127. &lt;li&gt;Prepare the input &lt;em&gt;data&lt;/em&gt; by chaining everything with appropriate &lt;strong&gt;open&lt;/strong&gt;..&lt;strong&gt;read&lt;/strong&gt;..&lt;strong&gt;strip&lt;/strong&gt;..&lt;strong&gt;split&lt;/strong&gt;.
  128. But sometimes &lt;strong&gt;numpy&lt;/strong&gt; is easier with a simple &lt;code&gt;loadtxt&lt;/code&gt;.&lt;/li&gt;
  129. &lt;li&gt;&lt;a href=&quot;https://jupyter.org/&quot;&gt;Jupyter Labs&lt;/a&gt; has come a long way.
  130. I never liked it back then. Now either via the browser or in VSCode, interactive python is a breeze.&lt;/li&gt;
  131. &lt;li&gt;Many times &lt;strong&gt;list|dict|tuple&lt;/strong&gt; comprehensions make the code very clean and easy to read.
  132. I&#x27;m thinking twice about the &lt;code&gt;for&lt;/code&gt; loops that I&#x27;m trying to implement.&lt;/li&gt;
  133. &lt;li&gt;&lt;a href=&quot;https://docs.python.org/3/library/typing.html&quot;&gt;Type annotations&lt;/a&gt; are very useful, even for small scripts, as they force you to decide on what you want to write.&lt;/li&gt;
  134. &lt;li&gt;&lt;code&gt;*[]&lt;/code&gt; and &lt;code&gt;[::1]&lt;/code&gt;&lt;/li&gt;
  135. &lt;li&gt;Many things are easy if I leverage &lt;code&gt;numpy, re, math&lt;/code&gt; and don&#x27;t try to reinvent the algorithms.&lt;/li&gt;
  136. &lt;li&gt;&lt;code&gt;functools.cmp_to_key&lt;/code&gt; works but I still find it a bit cumbersome to use.
  137. There should be a cleaner way to sort by user-defined comparators.&lt;/li&gt;
  138. &lt;li&gt;&lt;code&gt;numpy.where(condition)&lt;/code&gt; in 2D matrices gives two arrays with the indicies of the entries.
  139. Better use &lt;code&gt;numpy.argwhere(condition)&lt;/code&gt; and &lt;code&gt;.tolist()&lt;/code&gt;. The former case needs a lot of massaging to get a tuple of coordinates back&lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#npargwhere&quot;&gt;3&lt;/a&gt;&lt;/sup&gt;.&lt;/li&gt;
  140. &lt;li&gt;&lt;code&gt;scipy.spatial.distance&lt;/code&gt; has methods for spatial distance calculations that are very useful, namely &lt;code&gt;pdist&lt;/code&gt;, &lt;code&gt;cdist&lt;/code&gt;, and &lt;code&gt;squareform&lt;/code&gt;&lt;/li&gt;
  141. &lt;li&gt;&lt;code&gt;splitlines&lt;/code&gt; can shorten the loading of the inputs... something in the line of &lt;code&gt;open(0).read().strip().splitlines()&lt;/code&gt; to read from standard in.&lt;/li&gt;
  142. &lt;/ul&gt;
  143. &lt;h3 id=&quot;things-to-explore-in-the-future&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#things-to-explore-in-the-future&quot;&gt;Things to explore in the future&lt;/a&gt;&lt;/h3&gt;
  144. &lt;ul&gt;
  145. &lt;li&gt;The &lt;a href=&quot;https://en.wikipedia.org/wiki/Shoelace_formula&quot;&gt;Shoelace formula&lt;/a&gt;, gets the area of a simple polygon from its coordinates.
  146. I think I&#x27;ll need to use this on a urban agent based model I&#x27;m running now.
  147. As a follow up to this, the &lt;a href=&quot;https://en.wikipedia.org/wiki/Pick%27s_theorem&quot;&gt;Pick&#x27;s theorem&lt;/a&gt; is also important.&lt;/li&gt;
  148. &lt;li&gt;&lt;code&gt;numba&lt;/code&gt; This is exciting.
  149. Never touched it before, so I&#x27;m eager to look into it when I have a bit more time.&lt;/li&gt;
  150. &lt;li&gt;Go deep with &lt;code&gt;numpy&lt;/code&gt;.&lt;/li&gt;
  151. &lt;li&gt;Day 12 pointed in the direction of &lt;strong&gt;recursion&lt;/strong&gt;.
  152. I struggled with this exercise.
  153. Recursion is something that everybody understands until you really have to apply it to a new problem.
  154. Need to revisit this again. Not submitting any answers as I feel I didn&#x27;t solve it.&lt;/li&gt;
  155. &lt;/ul&gt;
  156. &lt;p&gt;&lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#day&quot;&gt;1&lt;/a&gt;&lt;/sup&gt; And we are only at day 20 at the time of writing. I&#x27;ll update this as &lt;strong&gt;AoC&lt;/strong&gt; progresses.&lt;br/&gt;
  157. &lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#github&quot;&gt;2&lt;/a&gt;&lt;/sup&gt; My &lt;a href=&quot;https://github.com/sixhat/adventofcode.com/&quot;&gt;&lt;strong&gt;AoC&lt;/strong&gt; repository&lt;/a&gt; contains my daily solutions in case you want to check my progress.&lt;br/&gt;
  158. &lt;sup class=&quot;footnote-reference&quot;&gt;&lt;a href=&quot;#npargwhere&quot;&gt;3&lt;/a&gt;&lt;/sup&gt; &lt;a href=&quot;https://numpy.org/doc/stable/reference/generated/numpy.argwhere.html&quot;&gt;https://numpy.org/doc/stable/reference/generated/numpy.argwhere.html&lt;/a&gt;&lt;/p&gt;

  165. <title>I'm giving Zed a try</title>
  166. <link>https://www.sixhat.net/2024/02-im-giving-zed-a-try.html</link>
  167. <description>
  168. &lt;h2 id=&quot;im-giving-zed-a-try&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#im-giving-zed-a-try&quot;&gt;I&#x27;m giving Zed a try.&lt;/a&gt;&lt;/h2&gt;
  169. &lt;pre&gt;&lt;code&gt;- Whose program is this?
  170. - It&#x27;s editor, baby.
  171. - Whose editor is this?
  172. - It&#x27;s VSCode&#x27;s.
  173. - Who&#x27;s VSCode?
  174. - VSCode&#x27;s dead baby, VSCode&#x27;s dead.
  175. &lt;/code&gt;&lt;/pre&gt;
  176. &lt;p&gt;In this case, the dead one might be VSCode.&lt;/p&gt;
  177. &lt;p&gt;I&#x27;ve been a &lt;strong&gt;vim/neovim/vscode&lt;/strong&gt; user for a couple of yeas now.
  178. In all this time the ammount of bloat VSCode has installed as grown to a point that I find myself thinking why I keep dragging this anchor of an editor.&lt;/p&gt;
  179. &lt;p&gt;It can&#x27;t even delete extensions from the support folder when I uninstall them.&lt;/p&gt;
  180. &lt;p&gt;Then there&#x27;s all those &lt;code&gt;node_modules&lt;/code&gt; folders filled with rogue JS for each plugin I use (that vscode never deletes).&lt;/p&gt;
  181. &lt;p&gt;So I decided to try &lt;a href=&quot;https://zed.dev/&quot;&gt;Zed&lt;/a&gt;.&lt;/p&gt;
  182. &lt;p&gt;It comes from the creators of Atom.
  183. After &lt;a href=&quot;https://zed.dev/blog/we-have-to-start-over&quot;&gt;repenting&lt;/a&gt; they went with &lt;a href=&quot;https://www.rust-lang.org/&quot;&gt;rust&lt;/a&gt; for Zed.&lt;/p&gt;
  184. &lt;p&gt;If the last two facts weren&#x27;t enough to get my attention, the &lt;a href=&quot;https://github.com/zed-industries/zed-fonts&quot;&gt;Zed mono and Zed sans fonts&lt;/a&gt; used in the editor got me 100%.&lt;/p&gt;
  185. &lt;p&gt;And for what I use a text editor for, zed is just blazing fast.
  186. What a surprise. Happy times in 2024!&lt;/p&gt;
  187.

  197. &lt;p&gt;&lt;a href=&quot;https://wcedmisten.fyi/post/visualizing-hospital-accessibility/&quot;&gt;William Edmisten&lt;/a&gt; made a great page about how he went on to study Hospital Accessibility based on data from OpenStreet. The read is about 15 min, but the author goes all the details needed to understand the process. Very impressive indeed. &lt;/p&gt;
  198. &lt;p&gt;Hm, with all the Hospitals closing in Portugal, should one do something inspired on his work?&lt;/p&gt;

  300. &lt;h2 id=&quot;writing-slides-structure-from-the-topics-slide-in-marp&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#writing-slides-structure-from-the-topics-slide-in-marp&quot;&gt;Writing slides structure from the Topics slide in marp&lt;/a&gt;&lt;/h2&gt;
  301. &lt;p&gt;I use marp to produce most of my slides and found it very interesting to layout the structure of the presentation in the &lt;em&gt;Agenda&lt;/em&gt;/&lt;em&gt;Topics&lt;/em&gt; slide. This slide acts as an organizer for the presentation.&lt;/p&gt;
  302. &lt;p&gt;I might write something like&lt;/p&gt;
  303. &lt;pre&gt;&lt;code&gt;## Topics
  304.  
  305. - Talk about awk
  306. - Explain why Julia rocks
  307.  - Show examples
  308. &lt;/code&gt;&lt;/pre&gt;
  309. &lt;p&gt;But then I have to create the slides, and the following snippet of shell code allows me to get the code for the slides in my presentation.
  310. It takes the &lt;code&gt;file.md&lt;/code&gt; and parses the lines starting with &#x27;- &#x27; and produces the outline like&lt;/p&gt;
  311. &lt;pre&gt;&lt;code&gt;---
  312.  
  313. ## Talk about awk
  314.  
  315. ---
  316.  
  317. ## Explain why Julia rocks
  318.  
  319. ---
  320.  
  321. ### Show examples
  322. &lt;/code&gt;&lt;/pre&gt;
  323. &lt;p&gt;This is all accomplished with old faithful &lt;code&gt;awk&lt;/code&gt;.&lt;/p&gt;
  324. &lt;pre&gt;&lt;code class=&quot;language-bash&quot;&gt;function mdIndex {
  325.  awk &#x27;/^- / {$1=&quot;&quot;;print &quot;\n---\n\n##&quot;$0 } / +- /{$1=&quot;&quot;;print &quot;\n---\n\n###&quot;$0}&#x27; $1
  326. }
  327. &lt;/code&gt;&lt;/pre&gt;
  328. &lt;p&gt;Just put it in &lt;code&gt;.zprofile&lt;/code&gt; and you can run it like this and get the results in the terminal,&lt;/p&gt;
  329. &lt;pre&gt;&lt;code class=&quot;language-bash&quot;&gt;$ mdIndex file.md
  330. &lt;/code&gt;&lt;/pre&gt;
  331. &lt;p&gt;or you can pipe it to &lt;code&gt;pbcopy&lt;/code&gt; and then paste the output into your editor of choice.&lt;/p&gt;
  332. &lt;pre&gt;&lt;code class=&quot;language-bash&quot;&gt;$ mdIndex file.md | pbcopy
  333. &lt;/code&gt;&lt;/pre&gt;

  342. <description>
  343. &lt;h2 id=&quot;the-wei-web-environment-integrity-api-proposal-from-google-is-dangerous-and-should-not-go-forward&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#the-wei-web-environment-integrity-api-proposal-from-google-is-dangerous-and-should-not-go-forward&quot;&gt;the wei (web environment integrity) api proposal from google is dangerous and should not go forward.&lt;/a&gt;&lt;/h2&gt;
  344. &lt;p&gt;wei will allow the webpage provider to arbitrary block you if you&#x27;re not using a certain browser, for example, via what is called an &lt;em&gt;attester&lt;/em&gt; that will certify that you (the receiver, consumer of content) are trustworthy. &lt;/p&gt;
  345. &lt;p&gt;the idea is that wei will force you, the client, to consume the content in the way they envisioned. this means no adblockers, no text-based browsers, no plugins that change the content you consume in any way. no non-human reading of the website. this basically means you&#x27;ll hand control over your computer environment or else you&#x27;ll get no service. &lt;/p&gt;
  346. &lt;p&gt;in any case google is already pushing code to their development github of chrome meaning that they will push the proposal with, or without, the approval of the w3c (the consortium managing web standards). they will enforce it on top of having 65% market share and probably forcing every google service to go through chrome (this means gmail, ads, youtube, etc...). &lt;/p&gt;
  347. &lt;p&gt;if you want to read about this potential danger go here:&lt;/p&gt;
  348. &lt;ul&gt;
  349. &lt;li&gt;&lt;a href=&quot;https://github.com/RupertBenWiser/Web-Environment-Integrity/blob/main/explainer.md#example-use-cases&quot;&gt;https://github.com/RupertBenWiser/Web-Environment-Integrity/blob/main/explainer.md#example-use-cases&lt;/a&gt;&lt;/li&gt;

  352. &lt;/ul&gt;
  353. &lt;p&gt;in any case my suggestion is to &lt;strong&gt;&lt;a href=&quot;https://www.mozilla.org/en-GB/firefox/new/&quot;&gt;move to firefox&lt;/a&gt;&lt;/strong&gt; and help diminish chrome share. No browser should have such power and as Chrome is becoming the new IE you should give the alternatives a try.&lt;/p&gt;

  414. <title>array based languages</title>
  415. <link>https://www.sixhat.net/2024/array-based-languages.html</link>
  416. <description>
  417. &lt;h2 id=&quot;array-based-languages&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#array-based-languages&quot;&gt;array based languages&lt;/a&gt;&lt;/h2&gt;
  418. &lt;p&gt;recently i came across &lt;a href=&quot;https://www.uiua.org/&quot;&gt;uiua&lt;/a&gt;, a rust based &lt;em&gt;array-oriented language&lt;/em&gt; that i fell in love immediately because of the aesthetics of the code.
  419. see the following online pad:&lt;/p&gt;
  420. &lt;html&gt;&lt;iframe frameborder=&quot;0&quot; height=&quot;740px&quot; src=&quot;https://www.uiua.org/pad?src=0_7_1__IyBTdW0gdGhlIG51bWJlcnMgYmlnZ2VyIHRoYW4gNTAgCiMgaW4gdGhlIHJhbmdlIFswLDEwMCkKLyvDlz41MC7ih6ExMDAK&quot; width=&quot;100%&quot;&gt;&lt;/iframe&gt;&lt;/html&gt;
  421. &lt;p&gt;it computes the sum of the numbers in the range &lt;code&gt;[0,100)&lt;/code&gt; that are greater than 50.
  422. although at first it looks a bit confusing, the use of unicode symbols makes is very pretty, in my eyes.&lt;/p&gt;
  423. &lt;p&gt;this is very different from &lt;a href=&quot;https://www.jsoftware.com/&quot;&gt;j&lt;/a&gt;, that only uses ascii characters and makes reading the code a bit harder—just my opinion.
  424. this doesn&#x27;t take merit from j, which has many features and is more mature, but aesthetics count.&lt;/p&gt;
  425. &lt;p&gt;code in `uiua`` reads left to right (ltr) and operators are to the left of their operands, making it resemble lisp like prefix notation.
  426. but it executes things in right to left (rtl).
  427. the authors even have a &lt;a href=&quot;https://www.uiua.org/docs/rtl&quot;&gt;faq entry about rtl&lt;/a&gt;.&lt;/p&gt;
  428. &lt;p&gt;i&#x27;m not an expert in these kinds of languages, but i&#x27;m going to look more into them during 2024.
  429. i&#x27;m tired of imperative programming languages and want to expand into different territories.&lt;/p&gt;
  430. &lt;p&gt;i&#x27;m considering being drastic about it.
  431. force myself to write everything i need during 2024 in any of the following:&lt;/p&gt;
  432. &lt;ul&gt;
  433. &lt;li&gt;lisp style lang (common lisp, scheme, racket, clojure, ...) – yes, i don&#x27;t mind the parenthesis.&lt;/li&gt;
  434. &lt;li&gt;array based languages (uiua, j, bqn, ...)&lt;/li&gt;
  435. &lt;/ul&gt;
  436. &lt;p&gt;and if something fails me i&#x27;ll use my loved python, but only in despair.&lt;/p&gt;

  443. <title>a simple ps1 bash prompt</title>
  444. <link>https://www.sixhat.net/2023/a-simple-ps1-bash-prompt.html</link>
  445. <description>
  446. &lt;h2 id=&quot;a-simple-ps1-bash-prompt-and-one-for-zsh-too&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#a-simple-ps1-bash-prompt-and-one-for-zsh-too&quot;&gt;a simple ps1 bash prompt (and one for zsh too)&lt;/a&gt;&lt;/h2&gt;
  447. &lt;pre&gt;&lt;code class=&quot;language-shell&quot;&gt;export PS1=&#x27;\n($?, $(cat /proc/loadavg | colrm 5 | xargs), $(du -hs | colrm 8 | xargs), $(ls -1 | wc -l)) \u@\H:\w/\n\$ &#x27;
  448. &lt;/code&gt;&lt;/pre&gt;
  449. &lt;p&gt;this outputs something like&lt;/p&gt;
  450. &lt;pre&gt;&lt;code class=&quot;language-shell&quot;&gt;(0, 0.85, 6.8g, 13) david@sixhat.net:~/
  451. $
  452. &lt;/code&gt;&lt;/pre&gt;
  453. &lt;p&gt;where the individual values are (in order):&lt;/p&gt;
  454. &lt;ul&gt;
  455. &lt;li&gt;the &lt;strong&gt;last command&lt;/strong&gt; exit code &lt;code&gt;$?&lt;/code&gt;&lt;/li&gt;
  456. &lt;li&gt;the &lt;strong&gt;load&lt;/strong&gt; on the cpu &lt;code&gt;$(cat /proc/loadavg | colrm 5 | xargs)&lt;/code&gt;&lt;/li&gt;
  457. &lt;li&gt;the &lt;strong&gt;size&lt;/strong&gt; of current directory &lt;code&gt;$(du -hs | colrm 8 | xargs)&lt;/code&gt;&lt;/li&gt;
  458. &lt;li&gt;the &lt;strong&gt;number&lt;/strong&gt; of files/dirs in current directory  &lt;code&gt;$(ls -1 | wc -l)&lt;/code&gt;&lt;/li&gt;
  459. &lt;li&gt;the &lt;strong&gt;user@host:folder&lt;/strong&gt; &lt;code&gt;\u@\h:\w/&lt;/code&gt;&lt;/li&gt;
  460. &lt;li&gt;the &lt;strong&gt;prompt type&lt;/strong&gt; (normal $ |root #) &lt;code&gt;\$&lt;/code&gt;&lt;/li&gt;
  461. &lt;/ul&gt;
  462. &lt;p&gt;notice that it has no colours. although colours are a nice feature to have, they don&#x27;t work in every terminal, but within your &lt;code&gt;.profile&lt;/code&gt; you can do conditional prompts based on colour support by the terminal.&lt;/p&gt;
  463. &lt;h4 id=&quot;what-about-zsh-prompts&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#what-about-zsh-prompts&quot;&gt;what about zsh prompts?&lt;/a&gt;&lt;/h4&gt;
  464. &lt;p&gt;well, zsh prompts are a little bit different to configure, but a similar one that i use in my macs is this:&lt;/p&gt;
  465. &lt;pre&gt;&lt;code class=&quot;language-shell&quot;&gt;export PS1=&#x27;
  466. %T %(1d.%B[First Day of Month]%b .)%U(%?,%j)%u %n@%m %F{red}%0~%f
  467. %F{green}%B%(!.%#.;)%b%f &#x27;
  468. &lt;/code&gt;&lt;/pre&gt;
  469. &lt;p&gt;The expansions are different from bash, so you are better off reading the &lt;a href=&quot;https://zsh.sourceforge.io/Doc/Release/Prompt-Expansion.html#Prompt-Expansion&quot;&gt;manual about expansions&lt;/a&gt;, but the above one can give you a nice start.&lt;/p&gt;

  476. <title>stealing this one, on how to study</title>
  477. <link>https://www.sixhat.net/2024/02-shamelessly-stealing-this.html</link>

  479. &lt;h1 id=&quot;im-shamelessly-stealing-from-this-reference&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#im-shamelessly-stealing-from-this-reference&quot;&gt;I&#x27;m shamelessly stealing from this reference&lt;/a&gt;&lt;/h1&gt;
  480. &lt;p&gt;while teaching I need sometimes to point students to good studying practices.
  481. I just found a great gem.
  482. I&#x27;m going to steel this one. Professor &lt;a href=&quot;https://cse.buffalo.edu/~rapaport/howtostudy.html&quot;&gt;Rapaport&lt;/a&gt; wrote a long page on how to study efficiently and I agree 100% with the content.
  483. It is really funny, useful and filled with some gems (i&#x27;m recursing gems in gem in gem in gem... ok... who cares, my text)
  484. Next time I get a student struggling with getting results because of bad habits, this will at the top of my list of recommendations.&lt;/p&gt;

  552. &lt;p&gt;This is just the snippet of code I use on pages that need syntax highlighting.
  553. I don&#x27;t add them directly to the template as other pages don&#x27;t need to load them.&lt;/p&gt;
  554. &lt;pre&gt;&lt;code class=&quot;language-html&quot;&gt;&amp;lt;html&amp;gt;&amp;lt;link rel=&quot;stylesheet&quot; href=&quot;https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/styles/default.min.css&quot;&amp;gt;

  557. &lt;/code&gt;&lt;/pre&gt;
  558. &lt;p&gt;Just copy and paste this at the end of markdown file&lt;/p&gt;
  559. &lt;html&gt;&lt;link href=&quot;https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/styles/default.min.css&quot; rel=&quot;stylesheet&quot;/&gt;

  593. &lt;p&gt;Agora encontrei uma &lt;a href=&quot;https://sjmulder.nl/en/textonly.html&quot;&gt;lista do Sijmen Mulder&lt;/a&gt; que tem ainda mais recursos. Alguns já eram conhecidos mas é interessante explorar as novidades.&lt;/p&gt;

  638. &lt;li&gt;Bill Gates published an extensive article on is blog about how he thinks this is a totally game changer technology. &lt;a href=&quot;https://www.gatesnotes.com/The-Age-of-AI-Has-Begun?WT.mc_id=20230321100000_Artificial-Intelligence_BG-TW_&amp;amp;WT.tsrc=BGTW&quot;&gt;The Age of AI has begun&lt;/a&gt; is a must read for anyone interested in these subjects. &lt;/li&gt;
  639. &lt;li&gt;&lt;a href=&quot;https://blog.mozilla.org/en/mozilla/introducing-mozilla-ai-investing-in-trustworthy-ai/&quot;&gt;Mozilla presented&lt;/a&gt; the &lt;a href=&quot;https://mozilla.ai/&quot;&gt;Moz://a.ai&lt;/a&gt;, a startup community aiming at building trustworthy and open-source AI. With the rapid advances in the field this will become a must if we don&#x27;t want some kind of violent reaction to it.&lt;/li&gt;

  695. &lt;p&gt;I&#x27;m not a prolific shell programmer (although my &lt;a href=&quot;https://www.davidrodrigues.org/research.html&quot;&gt;master&#x27;s dissertation&lt;/a&gt; leveraged bash + gawk and made the &lt;em&gt;programming&lt;/em&gt; part easy) but I used them for many small tasks that are repetitive and can be simplified via a script. &lt;/p&gt;
  696. &lt;p&gt;Writing those scripts for the shell (bash, or whatever) is hard because of some quirks in the language/system, like &lt;a href=&quot;https://www.gnu.org/software/bash/manual/html_node/Shell-Expansions.html&quot;&gt;shell expansions&lt;/a&gt; and &lt;a href=&quot;https://en.wikipedia.org/wiki/Glob_(programming)&quot;&gt;file globing &lt;/a&gt;
  697. Therefore, it is nice to have some sort of syntax checker for most small pickles.  &lt;a href=&quot;https://www.shellcheck.net/&quot;&gt;https://www.shellcheck.net/&lt;/a&gt; mitigates the problem by analysing your scripts for some common buggy patterns.&lt;/p&gt;

  709. &lt;p&gt;-- Dave, are you going to write that?&lt;/p&gt;
  710. &lt;p&gt;... as I was saying, to remember when all we had was small things. Code compiled
  711. to small sizes, websites were a few kB, computers were slow, but the slownness
  712. didn&#x27;t come from size of code, slow was just because of lack of chip power.
  713. These days we are all spoiled by the abundance of &lt;em&gt;processing power&lt;/em&gt;. &lt;/p&gt;
  714. &lt;p&gt;That is why this &lt;a href=&quot;https://benhoyt.com/writings/the-small-web-is-beautiful/&quot;&gt;text rings so many rights in a world full of wrongs&lt;/a&gt;.&lt;/p&gt;

  725. &lt;p&gt;A igreja deixou andar a comissão, e agora fez aquilo que já se esperava de uma organização podre até ao tutano. Matou os resultados de uma assentada. Cuspiu na cara das vítimas e ainda se riu. E o pior é que o fez não por uma razão de fé, ou de crença ou qualquer outra coisa, refugiou-se numa artimanha de um estado de direito que é a &quot;produção de prova&quot;. &lt;/p&gt;
  726. &lt;blockquote&gt;
  727. &lt;p&gt;&quot;Se essa lista de nomes for preenchida por factos, tanto nós como as autoridades civis podemos actuar&quot;&lt;/p&gt;
  728. &lt;/blockquote&gt;
  729. &lt;p&gt;O Sr cardeal-patriarca de Lisboa decidiu matar o processo de investigação aos pedófilos da igreja e argumentando que na justiça civil só o é o que se prova. Criou um artefacto para salvar a pele aos amigos pedófilos e predadores sexuais que a igreja portuguesa acoita. &lt;/p&gt;
  730. &lt;p&gt;&lt;strong&gt;Sr cardeal-patriarca, por vezes sabem-se coisas que não se podem provar.&lt;/strong&gt;&lt;/p&gt;
  731. &lt;p&gt;Ou isso ou então está com medo de PAGAR. Lembre-se que nos &lt;a href=&quot;https://en.wikipedia.org/wiki/Catholic_Church_sex_abuse_cases_in_the_United_States&quot;&gt;estados unidos a igreja terá pago mais de 4 mil milhões&lt;/a&gt; (uma tapezinha) desde 1980 a cerca de 17000 vítimas. Será que o este &quot;shutdown&quot; procura servir quem? os cofres da igreja portuguesa? Algumas dioceses nos EUA tiveram que pedir falência por causa dos escândalos, será que por cá já se estão a fazer as contas? é o que parece. &lt;/p&gt;
  732. &lt;p&gt;As vítimas sabem coisas que não podem provar e lá porque não se podem provar não quer dizer que não tenham acontecido e que os nomes... sim os nomes que o Sr quer esconder não passam de criminosos que a Igreja, abusando da lei do estado, procura esconder. Talvez, tal como noutros países não se consigam provar todos actos a ponto de condenar, mas talvez como noutros países se possam condenar pelo encobrimento os bispos, arcebispos ou cardeais que o praticam. E se não for possível pela justiça laica de que abusam, pelo menos da justiça divina da sua igreja não escaparão.&lt;/p&gt;

  766. &lt;li&gt;Although from 3 years ago, this &lt;a href=&quot;https://raganwald.com/2020/05/03/fractran.html&quot;&gt;FRACTRAN page&lt;/a&gt; by &lt;a href=&quot;https://braythwayt.com/&quot;&gt;Reg Braithwaite&lt;/a&gt; is pure intellectual joy.

  768. &lt;li&gt;An interesting project to create an &lt;a href=&quot;https://ultimateelectronicsbook.com/#&quot;&gt;Ultimate Electronics Book&lt;/a&gt;. Another one? Well they all need 2 things to work, be clear and be interactive. If not I can&#x27;t give them to my students.&lt;/li&gt;

Atendendo ao que representa esta medida não me admirava que em breve também Lisboa seguisse o exemplo. O modelo de funcionamento destes negócios representa o abuso completo do espaço público, com total desrespeito pelo espaço pedonal. Se ainda por cima o se tornam inseguras, não há como dar a volta ao texto e as gestões urbanas acabarão por impor restrições ou proibições completas. Sim, a culpa não é das marcas, mas dos utilizadores irresponsáveis. Mentira, também é das marcas que desenham um negócio baseado na apropriação do espaço público, como as esplandas do Covid que nunca mais desapareceram e que comem em muitos sítios mais de metade dos passeios. Mas há licenças. Então terminem-se.&lt;/p&gt;

  803. &lt;ul&gt;
  804. &lt;li&gt;Quem converter AL em arrendamento tem benefícios e isenções&lt;/li&gt;
  805. &lt;li&gt;Off-shores que venderem casas ao estado tem isenções&lt;/li&gt;
  806. &lt;/ul&gt;
  807. &lt;p&gt;Esta salganhada do arrendamento que o governo se prepara para criar mostra claramente que vai haver quem vai pagar a fatura, e esse alguém parecem ser os actuais senhorios que já alugam as casas. Então agora se um AL se converter em arrendamento do estado fica com isenção de IRS até 2030? Então alguém que está num mercado competitivo vai ficar com uma vantagem comercial de 25%? A lei da concorrência fica completamente desvirtuada. Os que já fazem aquilo que o estado pretende, pelos vistos podem ser sacrificados pelo estado e pagar a fatura. Vamos bem. &lt;/p&gt;

  814. <title>my approach to managing scratch projects with bash scripts</title>
  815. <link>https://www.sixhat.net/2023/my-approach-to-managing-scratch-projects-with-bash-scripts.html</link>

  817. &lt;h2 id=&quot;my-approach-to-managing-scratch-projects-with-bash-scripts&quot;&gt;&lt;a class=&quot;header&quot; href=&quot;#my-approach-to-managing-scratch-projects-with-bash-scripts&quot;&gt;My approach to managing scratch projects with bash scripts&lt;/a&gt;&lt;/h2&gt;
  818. &lt;p&gt;In R if I just want to test an idea I create a scratch project in /tmp . This will removed automatically on the next boot. This makes it easy to setup scratch folders without leaving much clutter behind. The problem is that the next time you open R after a reboot it will complaint about not finding the previous workspace. I also do the same thing with Markdown files and folders. To help me manage this I have a &lt;code&gt;new_project&lt;/code&gt; bash script in my bin folder that goes like this (only .r and .md versions shown but can easily be extended for your needs)&lt;/p&gt;
  819. &lt;pre&gt;&lt;code class=&quot;language-bash&quot;&gt;#!/bin/bash
  820. set -euo pipefail
  821.  
  822. __usage=&quot;usage: new_project name &amp;lt;type&amp;gt;
  823.  
  824.    type can be one of md, r, or any other... and accordingly it should open
  825.    and setup different folder structures
  826.  
  827.    name will be the folder name where the project exists.
  828. &quot;
  829.  
  830. make_folder () {
  831.    mkdir -p &quot;$1&quot;
  832.    cd &quot;$1&quot;
  833. }
  834.  
  835. project_md (){
  836.    make_folder &quot;$1&quot;
  837.    local today_file=&quot;$(date +%F).md&quot;
  838.    if test ! -f &quot;$today_file&quot;; then
  839.        touch &quot;$today_file&quot;
  840.    fi
  841.    open -a &quot;/Applications/Visual Studio Code.app/&quot; &quot;$today_file&quot;
  842. }
  843.  
  844. project_r (){
  845.    make_folder &quot;$1&quot;
  846.    local today_file=&quot;$(date +%F).r&quot;
  847.    if test ! -f &quot;$today_file&quot;; then
  848.        touch &quot;$today_file&quot;
  849.    fi
  850.    open -a &quot;/Applications/RStudio.app&quot; &quot;$today_file&quot;
  851. }
  852.  
  853. # Start logic bellow this line
  854.  
  855. if [ &quot;$#&quot; != 2 ]; then
  856.    echo &quot;$__usage&quot;
  857.    exit 1
  858. fi
  859.  
  860. if [ &quot;$2&quot; = &quot;r&quot; ]; then
  861.    project_r $1
  862. fi
  863.  
  864. if [ &quot;$2&quot; = &quot;md&quot; ]; then
  865.    project_md $1

  879. &lt;p&gt;Are there any models on creativity? Not creativity in a utilitarian way, like innovation, but creativity, just a theory of how creativity exists.&lt;/p&gt;
  880. &lt;ul&gt;
  881. &lt;li&gt;Exploring Creativity and Urban Development with Agent-Based Modelling - &lt;a href=&quot;https://jasss.soc.surrey.ac.uk/18/2/12.html&quot;&gt;https://jasss.soc.surrey.ac.uk/18/2/12.html&lt;/a&gt;&lt;/li&gt;
  882. &lt;/ul&gt;
  883. &lt;p&gt;Different factors are studied with ABM (transport, land use, residential segregation) and the authors found that there is a trade-off between economic progress and socioeconomic equity. &lt;strong&gt;Is Creativity elitist?&lt;/strong&gt; #FullRead&lt;/p&gt;

  887. &lt;li&gt;mixed land-use and population density&lt;/li&gt;
  888. &lt;li&gt;affordable urban and regional mobility&lt;/li&gt;
  889. &lt;li&gt;high levels of societal tolerance.&lt;/li&gt;
  890. &lt;/ul&gt;
  891. &lt;/li&gt;
  892. &lt;/ul&gt;
  893. &lt;p&gt;Notes:&lt;/p&gt;
  894. &lt;blockquote&gt;
  895. &lt;p&gt;&quot;... the starting point for theory building is establishing relevant stylised facts&quot;&lt;/p&gt;

  902. &lt;li&gt;§2.4 &quot;doubling the employment density (jobs per unit area) is associated with 2-6 percent rise in productivity&quot;. &quot;high density of interactions is associated with high levels of economic productivity&quot; (potential connection with imperfect information and in-person interactions)&lt;/li&gt;

  905. &lt;li&gt;§3.2 &quot;Axtell and Epstein (1994) classify ABMs from &quot;level 0&quot; types that broadly caricature real-world agent behavior to &quot;level 3&quot; where they are in quantitative agreement with both the macro- and &quot;micro-structures&quot; of the target system.&quot;

  927. &lt;p&gt;Read a paper on the process of writing Marginalia in books, both in print and digital versions, and how the e-reader versions makes annotating books much more difficult and having a very different nature and perceived value by the readers. The paper is &lt;a href=&quot;https://www.sciencedirect.com/science/article/abs/pii/S0740818817300099&quot;&gt;&quot;Marginalia in the digital age: Are digital reading devices meeting the needs of today&#x27;s readers?&quot; by Melanie Ramdarshan Bold and Kiri L. Wagstaff&lt;/a&gt;. They conducted a survey and the users self-reported there views on marginalia. There are many interesting points, namely the print vs digital, the pedagogical value of marginalia, the leisure vs educational marginalia, and one of the most fascinating, the individualistic vs social aspect of writing in the margins of books. &lt;/p&gt;
  928. &lt;p class=&quot;mar&quot;&gt;PS: Should I re-implement a marginalia system for this blog?&lt;/p&gt;

  952. &lt;p&gt;I&#x27;m really impressed how much love some people put into small works that are really well crafted.
  953. Two websites that have impressed me lately are the &lt;a href=&quot;https://solar.lowtechmagazine.com/&quot;&gt;Low&amp;lt;–Tech Magazine&lt;/a&gt;, a really well thought website with long reads that are inspiring and well written. More, it is powered by solar power! The second website that really impressed me recently is &lt;a href=&quot;https://rawtext.club/~sloum/&quot;&gt;Sloum&#x27;s&lt;/a&gt;, mainly because of the little software utilities he has coded and published. If you have time (and you should have time, or get time) take a look at these. &lt;/p&gt;

  964. &lt;p&gt;As the blue bird melts down I&#x27;ve decided to get back to social networks. I joined Mastodon. If you want to get out of the toxic/dictatorial world that Twitter has become and want to go back to fundamental community sharing in a decentralised way that no one can buy and destroy, give Mastodon a try. You can find me &lt;a href=&quot;https://datasci.social/@sixhat&quot;&gt;@sixhat@datasci.social&lt;/a&gt;&lt;/p&gt;
  965. &lt;p&gt;The main reason for choosing Mastodon is that it is a federated not owned centrally by one entity. For me, this decentralisation is of primary importance. If you don&#x27;t find a community that you like, you can join with your server, build your small community (even if it is only your family) interested in some particular topic, and still take part in a greater public discussion. &lt;/p&gt;
  966. &lt;p&gt;To start, &lt;a href=&quot;https://joinmastodon.org/servers&quot;&gt;choose a server&lt;/a&gt; on a topic that you are keen on and start following some people (you can follow people from other servers, you are not in a silo, or have reading limits) and some #hashtags. &lt;/p&gt;

  977. &lt;p&gt;I&#x27;ve been using RSS since its inception, and no, &lt;a href=&quot;https://www.google.com/search?q=site%253Asixhat.net++RSS+is+not+dead&quot;&gt;RSS is not dead&lt;/a&gt;, but my opml has a lot of dead wood in it and that is annoying. I&#x27;d like to have an RSS reader that would give me statistics on my feeds, readings, prefered feeds, etc... could it be an enterprise for personalized AI?&lt;/p&gt;
  978. &lt;p&gt;By the way, I mostly use newsboat as my reader.&lt;/p&gt;

  989. &lt;p&gt;I&#x27;m always interested in opportunities to learn new things, but like many, I struggle with information overload, in the digital world &lt;em&gt;entertainment&lt;/em&gt; is so prevalent that the drive to learn new things becomes subdued to the joy of rapid exploration.&lt;/p&gt;
  990. &lt;p&gt;In any case, I&#x27;ve come across a couple of references that I want to revisit in detail.&lt;/p&gt;
  991. &lt;ul&gt;
  992. &lt;li&gt;&lt;a href=&quot;https://giansegato.com/essays/edutainment-is-not-learning&quot;&gt;How to learn better in the Digital Age&lt;/a&gt; This points in some interesting directions: the biological aspect of learning, the physical effort needed, and the association between retention and physical action is something often forgotten. The need for &lt;em&gt;effort&lt;/em&gt; for learning to be successful. Nothing easy is worth much.&lt;/li&gt;
  993. &lt;li&gt;&lt;a href=&quot;https://notes.andymatuschak.org/A_reading_inbox_to_capture_possibly-useful_references&quot;&gt;The Reading Inbox&lt;/a&gt;This points (in the GTD style?) to the problem of the Reading Inbox — a problem I have (my Reading Inbox is over capacity). Maybe one should implement a Reading Inbox as a circular LinkedList with a fixed capacity. If it grows it starts overwriting older entries. Hm...&lt;/li&gt;

  1007. &lt;p&gt;A standard protocol for describing individual-based and agent-based models, the authors describe the ODD protocol that has become the &lt;em&gt;de facto&lt;/em&gt; standard to describe agent based models. &lt;/p&gt;
  1008. &lt;p&gt;In papers these ODD descriptions either appear inline (rare), but mostly appear as a supplementary material (common), and in some cases they also follow the software distribuition.&lt;/p&gt;

  1030. &lt;p&gt;I&#x27;ve used &lt;a href=&quot;https://github.com/junegunn/fzf&quot;&gt;fzf&lt;/a&gt; for a long time now. It works great and I&#x27;d recommend every power user to use fzf (or any other fuzzy logic search tool)&lt;/p&gt;
  1031. &lt;p&gt;One of the things I like about using it is to go to the folder of some file I&#x27;m working on. For example I use this alias &lt;code&gt;cdf&lt;/code&gt; to cd into the file directory. &lt;/p&gt;
  1032. &lt;p&gt;Just put the following alias in your shell&lt;/p&gt;
  1033. &lt;pre&gt;&lt;code&gt;alias cdf=&#x27;cd `dirname $(fzf)`&#x27;
  1034. &lt;/code&gt;&lt;/pre&gt;
  1035. &lt;p&gt;Then you can cdf, search, press enter and cd into the file&#x27;s directory. (Well, there&#x27;s also ALT-C, but who cares)&lt;/p&gt;
  1036. &lt;p&gt;You migth want to check &lt;a href=&quot;https://andrew-quinn.me/fzf/&quot;&gt;this blog post&lt;/a&gt; about fzf.&lt;/p&gt;

  1047. &lt;p&gt;Just came across Spacedrive — a new file explorer that is cross platform and aims to bring the same experience across OSes. It reminds a lot of apple Finder, and at this moment it doesn&#x27;t bring anything that would convince me to change to SpaceDrive. For Windows users and eventually Linux users it might provide a better user experience, but until it can offer something that blows Finder away... it has a steep mountain to climb. In any case it is a nice project to follow as the current release is still alpha — &lt;a href=&quot;https://www.spacedrive.com/&quot;&gt;Spacedrive.com&lt;/a&gt; &lt;a href=&quot;https://github.com/spacedriveapp/spacedrive&quot;&gt;SpaceDrive Github&lt;/a&gt;&lt;/p&gt;

  1058. &lt;p&gt;Axtell and Epstein[1] stated that an agent-based model performance can be characterised a a level, with any further level encompassing the previous:&lt;/p&gt;
  1059. &lt;p&gt;&lt;strong&gt;Level 0&lt;/strong&gt;: a &lt;em&gt;caricature&lt;/em&gt; of reality, as established through the use of simple graphical devices (allowing the visualisation of agent motion)

  1094. &lt;p&gt;This kind of asset is so valuable in a time when we have students wanting to do open, transparent and reproducible research. Good for any type of research but focused on Data Science. &lt;/p&gt;

  1120. &lt;p&gt;Many times I need to create an index of certain files in my computer, namely when they are spreaded over many subfolders. Using the utility &lt;strong&gt;tree&lt;/strong&gt; generates indices quickly and in a format that makes them very useful.&lt;/p&gt;
  1121. &lt;p&gt;For example, to find all PDF files: &lt;/p&gt;
  1122. &lt;pre&gt;&lt;code&gt;tree -P &#x27;*.pdf&#x27; --prune -H . &amp;gt; index.html

  1134. &lt;p&gt;I love &lt;strong&gt;static websites&lt;/strong&gt;, but what about if the &lt;em&gt;static&lt;/em&gt; was just markdown files and I let the client render everything via a Javascript library? &lt;/p&gt;
  1135. &lt;ul&gt;
  1136. &lt;li&gt;&lt;a href=&quot;https://dynalon.github.io/mdwiki/#!index.md&quot;&gt;MDWiki&lt;/a&gt; - This is used to run this website. Makes it very simple to use. One index.html file and you&#x27;re done.&lt;/li&gt;
  1137. &lt;li&gt;&lt;a href=&quot;https://chrisdiana.github.io/cms.js/&quot;&gt;CMS.js&lt;/a&gt; - Interesting, with more configuration/conventions to follow. An alternative in any case.&lt;/li&gt;
  1138. &lt;/ul&gt;
  1139. &lt;p&gt;(This website uses &lt;a href=&quot;https://rust-lang.github.io/mdBook/&quot;&gt;MDBook&lt;/a&gt; - This is highly recommended, even for bigger things other than a simple blog like this, although it is pre-rendered)&lt;/p&gt;

  1161. &lt;p&gt;Use package &lt;em&gt;xurl&lt;/em&gt; instead of &lt;em&gt;url&lt;/em&gt; in LaTeX documents to avoid having long urls going into the margin of the documents. This will break the long url into multiple lines without creating any issues. &lt;/p&gt;
  1162. &lt;p&gt;Just load &lt;em&gt;xurl&lt;/em&gt; with &lt;em&gt;usepackage&lt;/em&gt; instead of &lt;em&gt;url&lt;/em&gt; and every time &lt;em&gt;url&lt;/em&gt; is called &lt;em&gt;xurl&lt;/em&gt; will take over. &lt;/p&gt;
  1163. &lt;p&gt;Don&#x27;t know why this one escaped my knowledge for over 15 years, but well, learn something every day. &lt;/p&gt;

  1228. &lt;p&gt;I can&#x27;t really come around in my mind that modern computers are so bloated with stuff (99% unnecessary) that free space just disappears before your eyes at alarming rates.&lt;/p&gt;
  1229. &lt;p&gt;For many yeas I&#x27;ve been using some sort of treemapping app to visualize where has everything gone.&lt;/p&gt;
  1230. &lt;p&gt;My favorite is &lt;a href=&quot;https://www.omnigroup.com/more/&quot;&gt;OmniDiskSweepper&lt;/a&gt;. Takes little space, does its thing, allows you to act upon findings. What else would one need?&lt;/p&gt;
