      <description>&lt;p&gt;The title is the puzzle. It's a sentence where every word has been turned into a number. Can you decrypt it?&lt;/p&gt;

&lt;p&gt;No keys, no tricks with the alphabet order. Just numbers. Give it a shot before scrolling down.&lt;/p&gt;

&lt;h2&gt;
  
  
  Hints
&lt;/h2&gt;

&lt;p&gt;&lt;/p&gt;
  Hint 1
  &lt;br&gt;
Count the digits. 11 digits is roughly 100^5. What kind of characters have codes around 100?&lt;br&gt;


&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
  Hint 2
  &lt;br&gt;
Divide the first number by the second. The ratio is suspiciously clean.&lt;br&gt;


&lt;p&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
  Hint 3
  &lt;br&gt;
The third number is less than 1. Something got divided.&lt;br&gt;


&lt;p&gt;&lt;/p&gt;

&lt;h2&gt;
  
  
  Solution
&lt;/h2&gt;

&lt;p&gt;&lt;/p&gt;
  Solution (spoiler)
  &lt;p&gt;&lt;strong&gt;Plaintext: "Linus doesn't want his Linux to be called GNU/Linux."&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Each word is the product of the ASCII codes of its letters:&lt;/p&gt;

&lt;div class="table-wrapper-paragraph"&gt;&lt;table&gt;
&lt;thead&gt;
&lt;tr&gt;
&lt;th&gt;Ciphertext&lt;/th&gt;
&lt;th&gt;Computation&lt;/th&gt;
&lt;th&gt;Word&lt;/th&gt;
&lt;/tr&gt;
&lt;/thead&gt;
&lt;tbody&gt;
&lt;tr&gt;
&lt;td&gt;11810799000&lt;/td&gt;
&lt;td&gt;L(76) × i(105) × n(110) × u(117) × s(115)&lt;/td&gt;
&lt;td&gt;&lt;strong&gt;Linus&lt;/strong&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;12324312000&lt;/td&gt;
&lt;td&gt;L(76) × i(105) × n(110) × u(117) × x(120)&lt;/td&gt;
&lt;td&gt;&lt;strong&gt;Linux&lt;/strong&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td&gt;0.0000381952…&lt;/td&gt;
&lt;td&gt;GNU ÷ Linux = 470730 ÷ 12324312000&lt;/td&gt;
&lt;td&gt;&lt;strong&gt;GNU/Linux&lt;/strong&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;
&lt;/table&gt;&lt;/div&gt;

&lt;p&gt;And yes, the slash in GNU/Linux is evaluated as actual division.&lt;/p&gt;
&lt;h3&gt;
  
  
  How to crack it
&lt;/h3&gt;

&lt;ol&gt;
&lt;li&gt;**Digit count gives the word lengund 100, and 11 digits is about
100^5, so each word is probably five&lt;/li&gt;
&lt;li&gt;**The trailing zeros give away mungs rarely end in &lt;code&gt;000&lt;/code&gt;. It means
factors like &lt;code&gt;n&lt;/code&gt; (110) and &lt;code&gt;x&lt;/code&gt; (120)&lt;/li&gt;
&lt;li&gt;**The ratio gives away the letter00 is exactly 23/24, which is
115/120, or &lt;code&gt;s&lt;/code&gt;/&lt;code&gt;x&lt;/code&gt;. So the two wordthe sentence structure makes
Linus/Linux the obvious guess.&lt;/li&gt;
&lt;li&gt;**The fraction gives away the div 1207/31600800 as a fraction, and
1207 = 17 × 71. 71 is &lt;code&gt;G&lt;/code&gt;. That's GN&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;It even matches history: Stallman aswhile Linus has always just called it&lt;br&gt;
Linux.&lt;/p&gt;
&lt;h3&gt;
  
  
  Verify
&lt;/h3&gt;


&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="kn"&gt;from&lt;/span&gt; &lt;span class="n"&gt;math&lt;/span&gt; &lt;span class="kn"&gt;import&lt;/span&gt; &lt;span class="n"&gt;prod&lt;/span&gt;

&lt;span class="n"&gt;p&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="k"&gt;lambda&lt;/span&gt; &lt;span class="n"&gt;s&lt;/span&gt;&lt;span class="p"&gt;:&lt;/span&gt; &lt;span class="nf"&gt;prod&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nf"&gt;map&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nb"&gt;ord&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt; &lt;span class="n"&gt;s&lt;/span&gt;&lt;span class="p"&gt;))&lt;/span&gt;
&lt;span class="nf"&gt;print&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="nf"&gt;p&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;Linus&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;),&lt;/span&gt; &lt;span class="nf"&gt;p&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;Linux&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;),&lt;/span&gt; &lt;span class="nf"&gt;p&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;GNU&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt; &lt;span class="o"&gt;/&lt;/span&gt; &lt;span class="nf"&gt;p&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;Linux&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;))&lt;/span&gt;
&lt;span class="c1"&gt;# 11810799000 12324312000 3.81952355
&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;




&lt;p&gt;&lt;/p&gt;

&lt;h2&gt;
  
  
  Make your own
&lt;/h2&gt;

&lt;p&gt;Want to make it harder? Some ideas:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Map letters to primes (a=2, b=3, c=5, …) so the magnitude doesn't reveal the word length.&lt;/li&gt;
&lt;li&gt;Add an offset to each code before trailing zeros.&lt;/li&gt;
&lt;li&gt;Pick a sentence nobody can guess fest leak by far.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Drop your own ciphers in the comment&lt;/p&gt;

      <title>suddo – sudo password prompts without leaving your AI agent's chat</title>
      <dc:creator>sunu15712</dc:creator>
      <pubDate>Mon, 03 Aug 2026 03:37:02 +0000</pubDate>
      <link>https://dev.to/sunu15712/suddo-sudo-password-prompts-without-leaving-your-ai-agents-chat-2dgg</link>
      <guid>https://dev.to/sunu15712/suddo-sudo-password-prompts-without-leaving-your-ai-agents-chat-2dgg</guid>
      <description>&lt;p&gt;# suddo (superuser don't do)&lt;/p&gt;

&lt;p&gt;Sometimes AI needs to run commands with sudo (installing a package,&lt;/p&gt;

&lt;p&gt;reading a file in /etc, etc). But most MCP clients don't support&lt;/p&gt;

&lt;p&gt;creating a PTY, so you end up having to open a separate terminal&lt;/p&gt;

&lt;p&gt;just to type your password:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight console"&gt;&lt;code&gt;&lt;span class="gp"&gt;    claude code                    $&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="nb"&gt;sudo cat&lt;/span&gt; /etc/hosts
&lt;span class="go"&gt;    AI: blabla                     password:

&lt;/span&gt;&lt;span class="gp"&gt;    &amp;gt;&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="o"&gt;!&lt;/span&gt; &lt;span class="nb"&gt;sudo cat&lt;/span&gt; /etc/hosts
&lt;span class="go"&gt;    AI: please open a new terminal.
&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;p&gt;Annoying.&lt;/p&gt;

&lt;p&gt;With suddo:&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight plaintext"&gt;&lt;code&gt;AI calls the tool `execute_command`

The server asks you, rejects, or allows it based on your rules
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;

&lt;p&gt;If allowed:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;&lt;p&gt;If you don't have a valid sudo timestamp, it asks for your password&lt;/p&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;The command runs safely&lt;/p&gt;&lt;/li&gt;
&lt;/ol&gt;
