via: [WayBack] Hacker News – coinmon: In case you don’t want to install 61 packages [1] :) and [WayBack] The curl + jq based approach to check Bitcoin prices looks a bit more attractive than using a node.js package with 61 dependencies, doesn’t it? Source:… – ThisIsWhyICode – Google+
Function to call curl from bash:
$ coinmon() {
> curl "https://api.coinmarketcap.com/v1/ticker/?convert=$1" | jq ".[0] .price_$1"
> }
$ coinmon eur
"6988.4723188"
Or in Python (from the same HackerNew thread): [Archive.is] https://www.pastery.net/jnscrh/
#!/usr/bin/env python3
from urllib.request import urlopen
from decimal import Decimal
import json
def print_coin(coin):
print("{} ticker:".format(coin["name"]))
print("Price: {:,} EUR".format(Decimal(coin["price_eur"])))
print("Market cap: {:,} EUR".format(Decimal(coin["market_cap_eur"])))
print()
r = urlopen("https://api.coinmarketcap.com/v1/ticker/?convert=eur")
coins = json.loads(r.read().decode("utf8"))
for coin in coins:
if coin["id"] in ("bitcoin", "ethereum", "ripple", "monero"):
print_coin(coin)

As of 20170711, the servername ftp.xs4all.nl does not support the ftp protocol any more; xs4all clients can only use the server sftp.xs4all.nl on port 22.
I missed that because I hardly use ftp except for the few rare occasions where I was in an environment without ftp.
So recently I found out: good move!
Since I still need this every now and then (but far less often than 10 years ago), I have set up a very small ftp server at home with limited storage and very limited users that I can turn on/off when needed.
Much better solution.

Free and – unlike the also free [WayBack] dupeGuru – finds duplicate files – hasn’t crashed on my system yet or fails to add folders:

cd /Volumes/Backup/Backups.backupdb/Joshua\ Priddle’s\ MacBook\ Pro/Latest/Macintosh\ HD/Users/priddle
tmutil restore -v secret_docs.txt ~/
Learned from [WayBack] Restoring files from OS X Time Machine with Terminal.app:
- do not use
cp as it will give you wrong permissions
- do use
tmutil
More elaborate steps (including finding the backup in the first place) is at [WayBack] Commandline restoration of a file in Time Machine on OS X | Hacks for Macs

I had zypper being confused about the dist-upgrade between these snapshots:
< CPE_NAME="cpe:/o:opensuse:tumbleweed:20171125"
---
> CPE_NAME="cpe:/o:opensuse:tumbleweed:20171129"
It ran into this:
Problem: libopenssl-1_0_0-devel-1.0.2m-1.1.x86_64 conflicts with libopenssl-devel > 1.0.2m provided by libopenssl-devel-1.1.0g-1.1.noarch
Based on [WayBack] Re: [opensuse-factory] openssl dependency problems with snapshot 2017112 after discussing with DimStar, I choose to have zypper dist-upgrade to perform
deinstallation of libopenssl-1_0_0-devel-1.0.2m-1.1.x86_64
Now all is fine.
Thanks Dominique a.k.a. DimStar!

Interesting: https://github.com/MinBZK/OperatieBRP
[WayBack] The Netherlands saw a big I.T. project meant to deliver a new citizen registry system fail. So they did one thing right. All the source code is now on github… – Jan Wildeboer – Google+
It includes both documentation and source code.
A bit of browsing reveals at least some of the technologies used:
Most of the SQL code seems to be generated.
There are truckloads of .XML configuration files, typical for a Java environment. Some configuration is in .properties files.

SuSEconfig has been dead for a while, but still indexed at quite a few of the official sites stressing the importance to use it.
It used to apply the configuration in /etc/sysconfig to the system.
The rationale for removal was simple:
Let’s remove all SuSEconfig scripts since only YaST calls SuSEconfig but other tools like rpm and zypper do not call it.
If scripts are needed, they need to be invoked as part of the postinstall.
Now most services either know to directly handle the configuration data there (and apply it during reload/restart/start of the service), or have a tool (like postfix now has /usr/sbin/config.postfix) to apply the settings.

Note that the below solution works for any project raising the W1029 warning (not just from projects using Delphi Mocks) like
[dcc32 Warning] W1029 Duplicate constructor 'ClassName.ConstructorName' with identical parameters will be inacessible from C++
From my original text at [WayBack] Get rid of W1029 warning in Delphi compile mode · Issue #106 · VSoftTechnologies/Delphi-Mocks · GitHub:
By default the compiler will emit warnings like these for projects when using either of the Delphi.Mocks.Behavior or Delphi.Mocks.Expectation directly or indirectly:
[dcc32 Warning] W1029 Duplicate constructor 'TExpectation.CreateOnceWhen' with identical parameters will be inacessible from C++
They’re harmless as DUnitX doesn’t support C++. This particular warning type cannot be disabled on the unit or source line level which means you have to disable it on the project level by either:
- adding
{$WARN DUPLICATE_CTOR_DTOR OFF} anywhere to your .dpr project file
- modifying the the Project Options for your project (easiest is in the
All configurations - All platforms target):
- follow the path
Delphi Compiler, Hints and Warnings in the treeview on the left
- expand the
Output warnings node in the listview on the right
- set
Duplicate constructor/destructor with identical parameters will be inacessible from C++ to Error
A screenshot of the second option is below.
Note that the spelling mistake in Duplicate constructor/destructor with identical parameters will be inacessible from C++ is how it is in the IDE, but that as Google search string it will give limited results, so here are some back-ground references:
