How to sign a file on Linux with GPG - TechRepublic | https://www.techrepublic.com/
You might be asking yourself this question, "What's to stop anyone from generating a gpg key with my information and then sending bogus data to a client?" Truth is, not much. However, I do have one very easy "work around" for this. What I do is create a new signing key that lasts only a day, and then in the comment section during the creation, enter a unique phrase. When I send the file to the recipient, I will have them verify the file and have them repeat the comment. If the comment is correct, I will give them the go-ahead to decrypt and use the file. If the comment isn't correct, they have a bogus file on their hands.

mysql - Error Code: 1005. Can't create table '...' (errno: 150) - Stack Overflow | https://stackoverflow.com/
The problem in my case was trying to create a table (named "builds") that had a foreign key constraint in some other table, but the table those constraints pointed to didn't exist anymore. Removing the FK constraints allowed me to re-add the table.

linux - What does "key_load_public: no such file or directory" mean? - Super User | https://superuser.com/
It means literally what it says: there is no such file or directory that ssh wanted to access.

However, it talks about the file mentioned below, not above. You have just the regular public keys, but you do not have the SSH certificates for them (presumably because you just don't need them). OpenSSH however will always try to load the associated .pub-cert file for each identity key.

How Wonder Woman and The Last Jedi could make our politics worse | Toronto Star
It could do cultural work. Stowe’s novel galvanized abolitionist sympathizers, unnerved slaveholders and maybe even softened a few hard hearts. Nevertheless, Little Eva’s post-novelistic life as a commodity still functioned, in the words of one of her most severe critics, as an “introduction to consumerism.” Like other sentimental consumer products of the era, Eva responded to desires and beliefs consumers already had.

Thus, according to historian Robin Bernstein, while Eva emerged as the pinnacle of pious white innocence, the novel’s black characters (especially Uncle Tom and the slave girl Topsy) were marketed and sold to consumers as odious cultural stereotypes from which we have yet to fully recover. The circulation of Eva’s image sanded away the particularities of her character, and the intense intimacy that attended ownership during the period enabled her to become a vessel for reinforcing some very ugly cultural norms.

17.04 - Errors updating zesty packages - apt update/upgrade - Ask Ubuntu
As described in release notes. Zesty will be supported for 9 months until January 2018. Therefore you can use old-releases site, to install zesty packages.


You'll need to change the "partner" repository to use 'archive.canonical.com', though. A global search-and-replace won't work for that one, it'll leave 'apt-get update' in a broken state.

[TxMt] TextMate perl bundle issues | http://lists.macromates.com/
If you do, make sure you add a use Carp::Heavy; in the script you are running. I think this is due to clearing up a circular import that would happen otherwise (because of some cleverness in exception_handler.pm)


This was not AT ALL the problem I was having, but once I did a 'use Carp::Heavy;' I got this error message in the server logs:
foo.cgi: Attempt to reload Carp/Heavy.pm aborted., referer: https://foo.website/page
foo.cgi: Compilation failed in require at /usr/share/perl5/Carp.pm line 39., referer: https://foo.website/page
Version mismatch between Carp 1.11 (/usr/share/perl5/Carp.pm) and Carp::Heavy 1.36 (/var/www/perl5-local-lib/lib/perl5/Carp/Heavy.pm). Did you alter @INC after Carp was loaded?, referer: https://foo.website/page


and *that* led me to rearrange the imports so that Carp could Carp, after which it told me that I'd changed the API slightly for a module required by the CGI, and forgot to update it on this other server. So Perl was trying to Carp, but some trickery in the way all the modules were loaded (with a 'use lib' and 'local::lib' in there somewhere) was preventing it.

debian - How to use the command update-alternatives --config java - Stack Overflow | https://stackoverflow.com/
For this specific purpose, the package java-common contains a tool called update-java-alternatives.

In my case, 'sudo apt-get install --reinstall java-common' still didn't fix this after (sort of accidentally) installing then de-installing 'openjdk-9-jre' or 'jdk' left /etc/alternatives/java all fubar.

Then 'update-alternatives' was complaining about the symlink being dangling; so I did an 'ln -sf' to fix it, then I got this:
<code class=""># sudo update-alternatives --config java
There is only one alternative in link group java (providing
/usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java Nothing
to configure. update-alternatives: warning: forcing reinstallation of
alternative /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java because link
group java is broken</code>
after which it was pretty much working.

Go Ahead, Put that Preposition at the End! | https://www.dailywritingtips.com/
This is the kind of arrant pedantry up with which I will not put. --Churchill

Those who lay down the universal principle that final prepositions are “inelegant” are unconsciously trying to deprive the English language of a valuable idiomatic resource, which has been used freely by all our greatest writers except those whose instinct for English idiom has been overpowered by notions of correctness derived from Latin standards.

The legitimacy of the prepositional ending in literary English must be uncompromisingly maintained; in respect of elegance or inelegance, every example must be judged not by any arbitrary rule, but on its own merits, according to the impression it makes on the feeling of educated English readers.

security - What is the difference between a cer, pvk, and pfx file? - Stack Overflow | https://stackoverflow.com/
Windows .cer files are ASN.1 DER encoded (you can decoded these with 'dumpasn1' on Linux or use http://www.lapo.it/asn1js/ for a web version--don't upload private keys there, though).

You can also decode with OpenSSL:

<code class="language-bash">
openssl asn1parse -inform der -in SomeIssuer.cer

# or, given a .cer file from Windows, something like this works:
openssl x509 -inform der -in SomeIssuer.cer -fingerprint -sha1
</code>

This was a helpful guide for decoding the various file extensions:

<code>Here are my personal, super-condensed notes, as far as this subject pertains to me currently, for anyone who's interested:

Both PKCS12 and PEM can store entire cert chains: public keys, private keys, and root (CA) certs.
.pfx == .p12 == "PKCS12"
fully encrypted
.pem == .cer == .cert == "PEM"
base-64 (string) encoded X509 cert (binary) with a header and footer
base-64 is basically just a string of "A-Za-z0-9+/" used to represent 0-63, 6 bits of binary at a time, in sequence, sometimes with 1 or 2 "=" characters at the very end when there are leftovers ("=" being "filler/junk/ignore/throw away" characters)
the header and footer is something like "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" or "-----BEGIN ENCRYPTED PRIVATE KEY-----" and "-----END ENCRYPTED PRIVATE KEY-----"
Windows recognizes .cer and .cert as cert files
.jks == "Java Key Store"
just a Java-specific file format which the API uses
.p12 and .pfx files can also be used with the JKS API
"Trust Stores" contain public, trusted, root (CA) certs, whereas "Identity/Key Stores" contain private, identity certs; file-wise, however, they are the same.</code>

How to View a Certificate Fingerprint as SHA-256, SHA-1 or MD5 using OpenSSL | Symantec | https://knowledge.symantec.com/
Seems to work, even though '-fingerprint' doesn't seem to be in the 'openssl' man page:
<code class="language-bash">
# SHA-256
openssl x509 -noout -fingerprint -sha256 -inform pem -in [certificate-file.crt]

# SHA-1
openssl x509 -noout -fingerprint -sha1 -inform pem -in [certificate-file.crt]

# MD5
openssl x509 -noout -fingerprint -md5 -inform pem -in [certificate-file.crt]</code>

If they came from Windows (in .cer) format, use '-inform der' (DER = Distinguished Encoding Rule). Der!
<code class="language-bash">
openssl x509 -inform der -in SomeIssuer.cer -fingerprint -sha1 -noout

If the Exercise Class Descriptions From My Gym Were Honest – The Everywhereist | http://www.everywhereist.com/
But the gyms and studios I frequent should also be held accountable, because the descriptions on their website are woefully vague: “energizing,” “fast-paced,” and “emphasizing strength and form” mean absolutely nothing. I’ve had naps and bowel movements that met all those criteria. But I think gyms rarely use more accurate descriptions, like “vomit in front of strangers” and “question if that’s sweat or urine on your pants,” because these might deter a more discerning customer.

I Tried Soylent. It Didn’t Go Well. – Geraldine DeRuiter – Medium | https://medium.com/
For those unfamiliar with this “food” product, Soylent is a high-protein drink designed to appeal to lifehackers, dieters, and doomsday cult members who are maybe a little shy and don’t want to come out of their bunker for communal meals. It has an incredibly long shelf-life, and provides you nutrition without all the pesky side-effects that food usually has, like chewing, tasting like something, and being an excuse for human interaction.

Now, you can understand why I was slightly concerned about ingesting something developed by guys who felt that the prep work for corn dogs and ramen was too much for them. Also, please explain to me how much time and effort is possibly spent purchasing those food items. You can literally buy them at a gas station.

11 Signs You Might Be a Vegan… – Fit Yourself Club | https://fityourself.club/
Like, the meal that’s best for my body is grass-fed, organic, humanely-raised, breast-fed, trust-funded, private-school-educated beef, with bacon and cheese — specifically gruyere and Velveeta, covered in half and half, or whipped cream, if available… and ranch dressing.

There’s a common argument in favor of carnivorous eating, which claims that once our very ancient ancestors started hunting… fast forward and we, as a species, moved from the short bus to driving the bus. Put another way, fat and calorie-dense game, made our brains grow and that’s why we have fidget spinners and iPhones (i.e., we’re highly intelligent).
