      "body": "I've worn many hats over the years&hellip;one of my favorites is FontForge contributor. [Back on August 13<sup>th</sup>](https://github.com/fontforge/fontforge/pull/3852), I made it so when you close the Execute Script dialog, you won't lose the associated script.\n\nOne reason for that is I frequently write useful scripts which I accidentally lose when closing FontForge. Today I'll present one.\n\nI'm making a typewriter font&hellip;[have been since May](https://twitter.com/HW_BEAT_THAT/status/1134437602331725824)! One of the things that makes this font different is that when two same letters are nearby they do not look identical, unlike almost every font in existence&hellip;minus another font of mine, [Quaerite Regnum Dei](https://github.com/ctrlcctrlv/QuaeriteRegnumDei). 😉\n\nWhat I'm going for with this project is maximum realism. I've studied output of real typewriters a little too much, and tinkered with GIMP scripts ~~a little~~ *way* too much, to get acceptable procedurally generated output. So, the precomposed characters in this font, according to my vision, should look as if they were made on a typewriter&mdash;type the base letter, backspace, type the mark. Meaning, marks, within reason, must not move from letter to letter; &ntilde; and &atilde; must have the mark in the same place if overlaid on top of one another, same with &Ntilde; and &Atilde;, however I'm willing to imagine a typewriter with two versions of each mark, one for uppercase and lowercase letters.\n\nSo unlike basically all fonts where what you want to do is place anchors carefully on each letter, in this font we want uniformity. That means we can use the FontForge Python API to place our marks.  Another anomaly is that we really only need one `mark` (Mark to Base Positioning) class, let's call it `themarkclass`, even though this font has some top marks, bottom marks, even the Hebrew *dagesh* middle mark, because it's monospaced.\n\nHere's a script to figure out which characters should get marks:\n\n```python\nimport unicodedata\nf=fontforge.fonts()[0]\n\nfor g in f.glyphs(\"encoding\"):\n  e=chr(0 if g.unicode == -1 else g.unicode) # Encoding...\n  c=unicodedata.category(e) # Unicode \"category\", looks like e.g. \"Lu\"\n  d=unicodedata.decomposition(e) # Unicode \"decomposition\", for Ñ would be \"004E 0303\"\n  il=('L' in c and ('u' in c or 'l' in c) and not d) # Is \"e\" a base letter?\n  if il: print(g.glyphname, e, \"L\")\n```\n\nWe get some interesting output like:\n\n```\n...\ngrk_ALPHA Α L\ngrk_BETA Β L\ngrk_GAMMA Γ L\ngrk_DELTA Δ L\ngrk_EPSILON Ε L\ngrk_ZETA Ζ L\ngrk_ETA Η L\ngrk_THETA Θ L\ngrk_IOTA Ι L\ngrk_KAPPA Κ L\ngrk_LAMDA Λ L\ngrk_MU Μ L\ngrk_NU Ν L\ngrk_XI Ξ L\ngrk_OMICRON Ο L\ngrk_PI Π L\ngrk_RHO Ρ L\ngrk_SIGMA Σ L\ngrk_TAU Τ L\ngrk_UPSILON Υ L\ngrk_PHI Φ L\ngrk_CHI Χ L\ngrk_PSI Ψ L\ngrk_OMEGA Ω L\n...\n```\n\nAll right! And for our marks we can just say:\n\n```python\nim = 'M' in c\nif im: print(g.glyphname, e, \"M\")\n```\n\nNow we've got as well:\n\n```\n...\nuni05B0 ְ M\nuni05B1 ֱ M\nuni05B2 ֲ M\nuni05B3 ֳ M\nuni05B4 ִ M\nuni05B5 ֵ M\nuni05B6 ֶ M\nuni05B7 ַ M\nuni05B8 ָ M\nuni05B9 ֹ M\nuni05BA ֺ M\nuni05BB ֻ M\ndagesh ּ M\nuni05BF ֿ M\nshin_dot ׁ M\nsin_dot ׂ M\n...\n```\n\nAll that's left to do is use the FontForge API to add the marks...\n\n```python\nif il: g.addAnchorPoint(\"theclass\",\"base\",0,(0 if 'u' in c else -114))\nif im: g.addAnchorPoint(\"theclass\",\"mark\",0,0)\n```\n\nAnd let's also add the needed tables!\n\n```python\nf.addLookup(\"mark1\",\"gpos_mark2base\",(),((\"mark\",((\"latn\",(\"dflt\")),(\"cyrl\",(\"dflt\")),(\"grek\",(\"dflt\")))),)  )\nf.addLookupSubtable(\"mark1\", \"mark1-1\")\nf.addAnchorClass(\"mark1-1\", \"theclass\")\n```\n\n**Voil&agrave;!**\n\n\n[![2019-11-26-151059_3456x1656_scrot.png](https://cdn.steemitimages.com/DQmPj3zqggGDEgEvCFm6AtrNoQ4yhPP7xnfF8u5b18vNyh8/2019-11-26-151059_3456x1656_scrot.png)](https://cdn.steemitimages.com/DQmPj3zqggGDEgEvCFm6AtrNoQ4yhPP7xnfF8u5b18vNyh8/2019-11-26-151059_3456x1656_scrot.png))\n\nNow we can tell FontForge we want it to generate Latin-1 for us just by going to the **Element&rarr;Build** menu; as long as we have the letters needed, and the marks needed (it's best for Latin-1 to add 0-width marks to the block beginning at U+0300), it will build them. Be aware, if that's *not* true, it will do its best, and its best is often...terrible.\n\n![2019-11-26-152316_976x945_scrot.png](https://cdn.steemitimages.com/DQmbJprY8UZMERWsnr6HZikZEWF8MUJ8ZexEX2UDgAKk7mu/2019-11-26-152316_976x945_scrot.png)\n\n<sub>Can you tell which one FontForge generated?</sub>",

      "title": "8chan is Still Using CloudFlare",
      "body": "**TL;DR: 8kun (8chan) will not load unless clients pass CloudFlare's firewalls.**\n\nWhen Jim Watkins and son proudly claimed to the world and their users that they were going to be replacing CloudFlare's multimillion dollar network just for their 8chan website, I was skeptical. Many of their users, however, believed it; after all, they had not the necessary experience to realize what was being promised.\n\nSince then, they've dropped the «8chan» name, instead preferring to be called «8kun». I see no logical reason to begin doing so—the software is the same, the owners are the same, and the rules are the same. Some, [such as Ron Watkins to the Wall Street Journal](https://www.wsj.com/articles/notorious-8chan-forum-is-an-internet-nomad-11573909201), would say that a lack of /pol/ makes 8chan no longer 8chan. That seems dubious at best to me. As can be seen [in this archive](http://archive.is/tzA9C), among other places, and on 8chan itself when it is up, board creation was and is as of this writing still very much on the table; as the rules have hardly changed, to expect that a /pol/ or /pol/-like board will not reappear as soon as the world stops paying attention is a dubious proposition, and one I do not accept.\n\nLet's however analyze the network. How are they doing it, these intrepid entrepreneurs, out-competing CloudFlare, which jettisoned them? In which datacenters have they bought servers, which networking cables have they installed, which satellites have they launched?\n\nLet's stop kidding ourselves, Nick Lim has done none of that. After being kicked from network after network, and then registrar after registrar, rather impressively, they have for now found [an ISP that will allow their crusty ship to drop anchor and use its port](http://archive.is/RuyDQ). But they worry, oh you see. CloudFlare was so convenient! It had an excellent firewall, and stopped many attacks. If only they could find a way to use its network on the sly!\n\nThey've found a way. Observe:\n\n![2019-11-18-190814_3458x1644_scrot.png](https://cdn.steemitimages.com/DQmatZpFnU2pffdxhvFW2JGXngetYSU99y47P86bfEP6ieo/2019-11-18-190814_3458x1644_scrot.png)\n\nWhat are we looking at here? I too was in doubt. We are looking at the output of an nginx module known as [testcookie](https://github.com/kyprizel/testcookie-nginx-module), except [configured to use client-side AES](https://github.com/kyprizel/testcookie-nginx-module/blob/master/doc/usecases.txt#L112).\n\nWe don't need to worry so much about this; it's pretty much irrelevant. It's a small roadblock in the way of would be miscreants. Perhaps it can even stop a few who don't care enough to drive around it, and instead turn around. What's really interesting is the URL https://vanwatech.com/aes.js, which computes the AES needed to get 8kun to load.\n\nOh, computer! Tell me about VANWATECH.COM.\n\n```\n[fred@pc ~]$ whois vanwatech.com #?\n   Domain Name: VANWATECH.COM\n   Registry Domain ID: 2396981845_DOMAIN_COM-VRSN\n   Registrar WHOIS Server: whois.google.com\n   Registrar URL: http://domains.google\n   Updated Date: 2019-05-31T05:40:51Z\n   Creation Date: 2019-05-31T04:01:37Z\n   Registry Expiry Date: 2020-05-31T04:01:37Z\n   Registrar: Google LLC\n   Registrar IANA ID: 895\n   Registrar Abuse Contact Email: [email protected]\n   Registrar Abuse Contact Phone: +1.8772376466\n   Domain Status: clientTransferProhibited https://icann.org/epp#clientTransferProhibited\n   Name Server: LISA.NS.CLOUDFLARE.COM\n   Name Server: MARK.NS.CLOUDFLARE.COM\n   DNSSEC: unsigned\n```\n\n\nCloudFlare nameservers? Well, perhaps he's just using their free DNS, let's not jump to concl&mdash;\n\n```\n[fred@pc ~]$ dig A vanwatech.com +noall +answer # dig, you really doth protest too much\nvanwatech.com.\t\t299\tIN\tA\t104.27.148.220\nvanwatech.com.\t\t299\tIN\tA\t104.27.149.220\n```\n\nAnd of course 104.16.0.0/12 is CLOUDFLARENET, meaning, CloudFlare owns these IPs.\n\nSo what does it all mean? Well, to load 8kun your computer needs to pass an AES challenge. That challenge can only be passed if your computer knows where to get the script which says how to compute it, `aes.js`, from. `aes.js` is hosted on VANWATECH.COM. VANWATECH.COM is hosted on CloudFlare. In sum, *CloudFlare is defending 8chan today, 18<sup>th</sup> November 2019*.\n\nI call on CloudFlare to kick them off. They sent a strong message when they kicked 8chan off, and hopefully they won't allow them back in through this backdoor. VanwaTech's anti-DDoS service is nothing but some open source nginx module and CloudFlare's firewall.",
