Cool: @filmfranz made an advent calendar on Python data analysis featuring a lot of Pandas examples referring to source code found on the interwebz: [WayBack ] Data Science Advent – franz.media .
First example is to eliminate outliers in the below graph.
He also has a really cool (German) Playlist on data analysis with Python called Datenanalyse in Python and has a great site with examples at franz.media .

Delphi tip of the day:
{$WARN UNSUPPORTED_CONSTRUCT ERROR}
It will throw a compiler error when you use an attribute that isn’t defined as the above [WayBack ] turns a warning into an error as normally [WayBack ] UNSUPPORTED_CONSTRUCT is only a warning.
Which means that this code now fails:
type
TmyClass = class
[djhgfskdhgks]
procedure One;
end;
Thanks [WayBack ] +Agustin Ortu for posting this tip!
I wish I had known this when I found the G+ post leading to On turning “W1025 Unsupported language feature: ‘customattribute’” into a compiler error.

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 :
Read reviews, compare customer ratings, see screenshots, and learn more about Duplicate File Finder for files & folders. Download Duplicate File Finder for files & folders for Mac OS X 10.9 or later and enjoy it on your Mac.

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

I had zypper being confused about the dist-upgrade between these snapshots:
< CPE_NAME="cpe:/o:opensuse:tumbleweed:20171125"
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 !
