|
||
|
|
<p>While the idea is commendable, I think the proposed solutions have a number of
|
||
|
|
problems:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Having an open standard only means having <em>multiple</em> "open" standards. <a href="https://xkcd.com/927/">XKCD
|
||
|
|
explained this pretty well</a>.</li>
|
||
|
|
<li>Exporting data could, indeed, be in different formats, but using a database
|
||
|
|
could also mean that each application would use their own schema (and
|
||
|
|
remember the thing about the standards and everyone having their own?).</li>
|
||
|
|
<li>As the author pointed, creating an API is costly. Why would some company
|
||
|
|
implement the API when they can do nothing and save money?</li>
|
||
|
|
<li>Worse: In a time when "data is the new oil", why would companies share their
|
||
|
|
oil well?</li>
|
||
|
|
</ul>
|
||
|
|
<p>I don't mean to diss the post, but there are a few things that need to be
|
||
|
|
fixed before we can dream of something like this -- for example, closing the
|
||
|
|
damn data-oil well.</p>

<h2 id="latency-in-asynchronous-python"><a href="https://nullprogram.com/blog/2020/05/24/">Latency in Asynchronous Python</a></h2>
|
||
|
|
<p>I'm not sure I follow the author description on how to solve the problem
|
||
|
|
presented.</p>
|
||
|
|
<p>Thing is, async (in any form) cannot be compared with threads, which seems the
|
||
|
|
initial idea on the description of the problem. Async is <em>cooperative
|
||
|
|
multitasking</em>, which means someone has to say "I'm done" so another task can
|
||
|
|
continue; by using a heartbeat task but doing I/O (<code>print</code>) and creating 200
|
||
|
|
async tasks, you're actually measuring how long the event loop wasn't allowed
|
||
|
|
to continue.</p>

<h2 id="ebay-port-scans-visitors-computers-for-remote-access-programs"><a href="https://www.bleepingcomputer.com/news/security/ebay-port-scans-visitors-computers-for-remote-access-programs/">eBay port scans visitors' computers for remote access programs</a></h2>
|
||
|
|
<p>In today's "Let's Abuse The Web To Find a New Way To Track People", some
|
||
|
|
people found out that the eBay website (yes, the website, not an app or
|
||
|
|
something like that) is using WebSockets (yes, websockets, not some fancy
|
||
|
|
technology, not some raw socket thingy) to do a port scan on the user's
|
||
|
|
computer.</p>
|
||
|
|
<p>There are two things that will happen now: People will start looking for those
|
||
|
|
things and stupid people will add that to their websites.</p>
|
||
|
|
<p>Maybe browsers could block websockets to one single address and, once it is
|
||
|
|
used, the site can't open a new one on a different address/port.</p>

|
||
|
|
<p>Macros is a part of Rust I still have to explore. This post describes one of
|
||
|
|
the simples macro types Rust have (there are three).</p>

|
||
|
|
<p>On my last live (it was in Portuguese, sorry English speakers), we discussed
|
||
|
|
the fact that my toy project had no tests -- in my defence, that was kinda
|
||
|
|
intentional, as all I'm doing is exploring more of the language.</p>
|
||
|
|
<p>An just out of the blue this post appears, which describes a bunch -- maybe I
|
||
|
|
bit too much -- of testing strategies for Rust code.</p>
|
||

<h2 id="just-how-i-organize-large-rust-programs"><a href="https://rodarmor.com/blog/tour-de-just">Just: How I Organize Large Rust Programs</a></h2>
|
||
|
|
<p>And just related to the previous event (you know, the live discussing Rust
|
||
|
|
code), I was also reorganizing my code, and now have a few more ideas on what
|
||
|
|
to do in the future.</p>

<h2 id="beyond-remote"><a href="https://vimota.me/writing/beyond-remote">Beyond Remote</a></h2>
|
||
|
|
<p>A good collection of points now that large tech companies switched to remote
|
||
|
|
working (some as "remote first" now) about what may and what may not work
|
||
|
|
straight away when a company switches to remote working.</p>

<h2 id="the-shapes-of-code"><a href="https://www.fluentcpp.com/2020/01/14/the-shapes-of-code/">The Shapes of Code</a></h2>
|
||
|
|
<p>This is one hell of an interesting post: Describing code by its shape --
|
||
|
|
basically, what you see in one of those "minimaps" -- instead of their
|
||
|
|
content. The curious parts is that it describes "what" the shape means and how
|
||
|
|
it can be improved in some refactoring.</p>

<h2 id="the-public-domain-is-the-rule-copyright-is-the-exception"><a href="https://www.eff.org/deeplinks/2020/01/public-domain-rule-copyright-exception">The Public Domain Is the Rule, Copyright Is the Exception</a></h2>
|
||
|
|
<p>I understand what the EFF is trying to say here but, at the same point, we
|
||
|
|
have to understand that copyleft -- the thing that powers every open source
|
||
|
|
project today -- <em>is</em> based on copyright. The thing that prevents open source
|
||
|
|
being abused is the fact that is copyrighted by someone, and that someone will
|
||
|
|
tell exactly what others can do with the code. It's the copyright that
|
||
|
|
protects it from being snatched by someone else and being used to lock-in
|
||
|
|
users.</p>
|
||
|
|
<p>Maybe the idea of copyright is being abused in a lot of places, but it doesn't
|
||
|
|
mean it is (totally) broken.</p>
|
||
|
|
<p>One thing to keep in mind here: Public Domain means anyone can do anything
|
||
|
|
with it. It could mean anyone could pick an free software and turn it into a
|
||
|
|
locked-in version of it.</p>

<h2 id="what-does-free-libre-open-mean"><a href="https://wiki.snowdrift.coop/about/free-libre-open">What Does <em>Free/Libre/Open</em> Mean?</a></h2>
|
||
|
|
<p>This is a quick and good explanation of the old discussion of the difference
|
||
|
|
between "free software" and "open source".</p>
