if you're mediocre clearance work is great. just work for one of the big ol defense contractors who look to put butts in seats. but you're not going to be allowed to be creative at all with your work, the people you are going to work with are going to be mediocre, your hands will be completely tied by bureaucracy a lot of times. and more likely than not the work environment is going to be poo poo.

History
Some folks may state that Chocolatey is insecure. That is based on older information and is incorrect to be stated in that way. Feel free to correct the person with "You mean Chocolatey used to be insecure."� and then point them to this page (https://chocolatey.org/security). It is correct that there were security concerns. However, all known concerns have been corrected and/or have a plan to be resolved (e.g. package signing). As we learn of new security concerns we put together a plan to resolve those issues with a priority that each CVE (common vulnerabilities and exposures) requires.

Chocolatey has had multiple security audits and findings have been corrected.

Past Security Concerns
These are things that used to be security concerns. They are listed here for historical purposes in case questions come up or someone states misinformation.

~~Installs without prompting for confirmation~~ - not true as of 0.9.9. Chocolatey by default will stop and ask you to confirm before changing state of the system, showing you the script it wants to execute.
~~Anybody can put packages up on the community feed and they could be malicious~~ - we put package moderation in place in October 2014. All packages coming in are now moderated BEFORE they are open to the public. See http://codebetter.com/robreynolds/2014/10/27/chocolatey-now-has-package-moderation/ for more details.
~~Downloads packages from S3 over HTTP (subject to DNS poisoning)~~ - this was corrected in March 2014 (https://github.com/chocolatey/chocolatey.org/issues/70)
~~Site doesn't require HTTPS (could be subject to DNS poisoning)~~ - https://github.com/chocolatey/chocolatey.org/issues/126 (closed completely in November 2014)
~~Downloads files from the internet with no integrity check~~ - we've added checksumming in August 2014 and started enforcing it by default for non-secure downloads with 0.10.0 in August 2016. Secure downloads will also require checksums sometime in 2017 (but can be flipped on with choco feature disable -n allowEmptyChecksumsSecure or with a runtime switch).
~~Poor permissions with c:\Chocolatey at root (allows attacker to gain Admin perms through specially crafted exes dropped in bin folder, among other things)~~ - we don't install here by default anymore. We install to C:\ProgramData\chocolatey by default for more secure permissions. The default location is locked down to explicitly to Administrators starting in 0.9.10.

Yeah someone was telling me today that package manager poo poo is something obscene like 20% of github traffic, and is a major drain on their systems. I think they should cut that poo poo off at the knees for public repos, but that's probably why I'm not in charge.

i had to get shift-jis working on an old label printer here that hooked up by serial port. it turned out that you had to send the hex codes as ascii characters

like, for example, if you wanted to print 軌, that maps to 0x8b4f in shift-jis, so you would actually have to send the string '8b4f' in ascii, doubling the data size and at least quadrupling the dev time required to figure out that's what the lovely instructions were telling you to do

there is a special place in hell for the people who write label printer firmware. you get all the downsides of dealing with printers, plus all the downsides of industrial hardware, plus all the downsides of weird proprietary comms protocols

sentry does what it says on the box, for sure.

they're just a special version of a log aggregator though. if you don't already have a log aggregator, get one of those running first. you can build most of the same features into splunk or ELK or whatever.

you can self host sentry, it's just a django app + redis so it's not too bad. you get the user + request data along with any exceptions which is super helpful. I like it

still loling about the rm -rf

e: i don't now poo poo about postgres but it looks like "YP" is a huge fuckup that did literally everything wrong in the timeline they published.

it looks like "YP" had hosed up their staging environment trying to get replication running (which is coincidentally their backup) and then called it a day because they couldn't figure out how to unfuck it without the help of someone who was out that day.
later, YP deals with spamming on their DB poorly, causing some data to get corrupted and db2 to poo poo itself.
In a effort to get replication to work into db2 again (note that trying to get replication up in staging is what caused YP to gently caress it up in the first place) YP had the brilliant idea of loving with database settings and then running a rm -rf command on prod.
i have no idea why they can't use db2 to recover from except that maybe the postgres instance ate itself because of aforementioned corrupted data. they could recover from staging but their "web hook data", whatever that means, is not backed up into staging.
Also they apparently have no idea what the postgres settings for prod is supposed to be (and never backed that up either).

lets say the volume were to change, whats the best way to update that value so that if tries to read the volume at the same time as the event is updating the value? ideally i think i would like the read to just pause until the event completes but idk

Strumpy posted:

it was surprisingly trivial - all I had to do was alias a class containing an array (???) over the list:

code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var bar = new hello {a = new List<int> { 8, 6, 7, 5, 3, 0, 9 } };
            for (var i = 0; i < bar.b.b.Length; i++)
            {
                Console.WriteLine(bar.b.b[i]);
            }
            Console.WriteLine(bar.b.b.Length);
            Console.WriteLine("hi");
            bar.a.Add(69);
            bar.a.Add(420);
            bar.a.TrimExcess();
            for (var i = 0; i < bar.b.b.Length; i++)
            {
                Console.WriteLine(bar.b.b[i]);
            }
            Console.WriteLine(bar.b.b.Length);
            Console.Read();
        }
    }

    [StructLayout(LayoutKind.Explicit)]
    struct hello
    { 
        [FieldOffset(0)]
        internal butt b;
        [FieldOffset(0)]
        internal List<int> a;
    }

    class butt
    { 
        public int[] b; 
    }
}

it could be plausibly useful in some scenarios where your List's capacity is�the same as its length, which you can do either by initializing it to the right size, getting lucky (default capacities seem to be 2^n, at least at these small sizes), or by�using TrimExcess, which�I feel makes the whole thing redundant anyways

it Seems To Work under a few different compilation settings (debug/release, x86/64) but still lol

yeah if the read thread raises the event that's what'll call the event handler. if only one thread is writing the volume level and multiple threads are reading it, i don't think you need to worry about thread safety, it's only a concern if multiple threads are reading *and* writing
