MKTUNES(1) User Commands MKTUNES(1) NAME mktunes - convert GNUtunesDB's XML into iTunesDB format SYNOPSIS mktunes [OPTION]... DESCRIPTION Convert GNUtunesDB.xml into iTunesDB format --help display this help and exit --version output version information and exit -m, --mount=DIRECTORY iPod mountpoint. Default is $IPOD_MOUNTPOINT -n, --ipod-name=NAME iPod Name (For unlabeled iPods). iTunes displays this name, not the label. -v, --volume=VALUE Adjust volume +-VALUE% (example: --volume +5) -e, --energy Save energy (= Disable scrolling title) -g, --fwguid=HEXVAL Enforce iPod serial/firewire-guid. Late 2007 iPod models (3gen Nano, Classic, Touch) refuse to work unless the iTunesDB has been signed with a sha1 hash. This hash helps to detect corrupted data‐ bases, prevents sharing an iTunesDB between multiple iPods and locks out non-apple software. GNUpod is able to create the required hash value if it knows the iPods serial number, this is a 16 chars long hex value such as: '000ba3100310abcf' and should be autodetected on GNU/Linux (via /proc/bus/usb/devices) and Solaris (via prtconf -v). Use this switch to set the serial if the autode‐ tection somehow fails to find the correct serial number of your iPod. You can also specify the value in your configuration file (gnupodrc) as 'mktunes.fwguid = 000ba3100310abcf'.

D3 also allows us to load real data in various formats; in this tutorial we will use a .csv file.
D3 uses the Fetch-API which allows loading and parsing of data files such as CSV, JSON and TSV. This type of call returns a promise where the loaded data can be used after a .then(function(data){ }) function and the error handling can be done inside .catch(function(error){ })
d3.csv("fruit.csv")
.then(data => console.log(data))
.catch(error => console.log(error));
D3 loads data asynchronously, so that interaction with the browser is not hampered while loading (scripts not related to the data can still run in the meantime). To signal that the loading is complete, D3 calls the .then(data => { }) function. This is an important concept, as it means for developers that code which depends on the data should only exist inside the .then(data => { }) function.
D3 loads all our data as strings, so we have to convert it to numbers to work with it. This can be done with the "+" operator.
data.size = +data.size;
But as this has to be done for every item in the data set, you have to iterate over all items, either by using a loop or with the following statement:
data.forEach(d => d.size = +d["size"]);


The International Space Station (ISS) is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. It is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.
The space station orbits Earth at an average altitude of approximately 250 miles. It travels at 17,500 mph. This means it orbits Earth every 90 minutes. The map below shows the current location of the International Space Station.
The space station has been continuously occupied since November 2000. Currently, the crew live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.
These are the spacecraft that are currently docked at the space station.
Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground.


This 19th century French writer is best-known for being the master of short stories. One of his most famous and internationally-acclaimed books is "Boule de Suif", although we would also highly recommend "Bel Ami".
Nominated for the Nobel Prize in Literature in 1948, Colette was an actress, journalist, novelist, and (interestingly) a French mime. Made a Grand Officier de la Légion d'Honneur (one of the highest honours in France) in 1953, she is best known for her novel "Gigi", but also for "Claudine à l'école" (Claudine at School), which was one of her first novels (published in 1900). One of her greatest quotations was : "You will do foolish things, but do them with enthusiasm". If you're interested, a live-action film about her life (where she is protrayed by Keira Knigthley) recently came out.
This stew is perfect for winter. Usually made with beef, red wine, onions, and carrots, it was first documented in the 19th century and has become a staple of Parisian bistrots.
Better known as "-M-" (his stage name), Matthieu Chédid comes from a very artistic family and has been performing hits since the late 1990s. His more well-known songs include "Je dis aime", "Onde Sensuelle", and "Mama Sam". He recently announced the release of his newest album ("Lettre infinie"), which will be released in 2019.

Serialization
|
shared_ptr
illustrates the straightforward way of serializing a moderately complicated class structure.
Unfortunately, this way of doing it suffered from some undesirable features
shared_ptr
.
The shared_ptr
interface has been included
in std::tr1
and may someday be included in the standard
C++ library. An implementation which depends only on the public interface can be guaranteed to
function with any other future implementation of shared_ptr
.
template<class Archive, class T>
inline void save(
Archive & ar,
const boost::shared_ptr<T> &t,
const unsigned int /* file_version */
){
const T * t_ptr = t.get();
// just serialize the underlying raw pointer
ar << boost::serialization::make_nvp("px", t_ptr);
}
template<class Archive, class T>
inline void load(
Archive & ar,
boost::shared_ptr<T> &t,
const unsigned int file_version
){
T* r;
// recover the underlying raw pointer
ar >> boost::serialization::make_nvp("px", r);
// To Do - match up with other shared pointers which
// use this same raw pointer.
...
}
In principle, this is very much simpler than the original implementation. Completion of
this code requires:
shared_ptr
instances.
weak_ptr
.
boost::serialization::shared_ptr.hpp
Note that if your code needs to read archives created under boost version 1.32, you will have to include the following
#include <boost/serialization/shared_ptr_132.hpp>
#include <boost/serialization/shared_ptr.hpp>
rather than just
#include <boost/serialization/shared_ptr.hpp>

| exit {remoter} | R Documentation |
This function cleanly shuts down the remoter server the client
is currently connected to, as well as shutting down the client.
One can also use q()
(while the client is running), and
this will not close the active R session on the client.
exit(client.only = TRUE, q.server = TRUE)
client.only |
Logical; if |
q.server |
Logical; if |
Exit the remoter client/server.
Returns TRUE
invisibly on successful exit.

SRE/DevOps skills that companies want
What skills do companies really want when they are looking for DevOps / SRE professionals? I’ve analysed 50 job postings to tell you what companies want when they are hiring for DevOps and SRE (Site Reliability Engineer) positions.
P.S - In this post, I am going to treat DevOps and Site Reliability Engineering as the SAME thing.
Most of the time companies don’t really know what they want and they just go with the flow. Meaning: “if Google invents a new term (SRE) and says that an SRE must do this, this and that, this probably should be a good thing and my company need this kind of person. So let’s open a position, call it SRE and put the same requirements everybody is asking for.”
Let me explain how I did this experiment:
I’ve searched for the job positions on these sites:
- Company website
- Random Google search (just typing the position name)
The way it works is:
I’ve read the entire job description and its requirements. I took notes on which requirement regarding the position was mentioned most.
For example:
If a job posting says it requires Python programming OR Java OR Go I will give one point for each mention.
If another job posting only says Python as a requirement I’ll give one point for the Python mention leaving Python with 2 points (2 mentions), Go with 1 point (1 mention) and Java with 1 point (1 mention). Very simple huh?
You got the point. 1 mention, 1 point.
I separated the requirements in some subjects :
- PROGRAMMING LANGUAGES
- AUTOMATION
- CLOUD
- CONTAINERIZATION
- MONITORING
- LOGGING
- CI / CD (Continuous Integration / Continuous Deployment)
- OPERATING SYSTEM(S)
Here are the results:
Programming Languages
We can see that on this subject there is a BIG winner: Python. Since Python is a multi purpose language and it’s very easy to read I’m not surprised it is the number one choice for companies that want their DevOps / SRE future employees to know. Linux comes with Python out-of-the-box and it’s much more fun to write scripts in Python than it is in Shell Script. Although, notice that Shell Script is still kinda relevant for these positions. So it’s better to know a bit. There is a lot of legacy scripts written in Shell Script and you for sure will give maintenance in one of those during your SRE / DevOps career. If I were an Infrastructure Engineer or Technical Support guy/gal wanting to go the DevOps / SRE way I would start to learn Python ASAP. Another interesting thing is the rise of Go as a language for DevOps / SRE purposes. Docker was written in Go and the language has a focus for what is called systems programming. We should expect Go rising more and more on the DevOps / SRE space. Better keep an eye on it…
Cloud
Another BIG winner here: Amazon AWS ecosystem. A lot of companies run their services on AWS and they want people capable of dealing with that. So better learn the AWS ecosystem as well. It’s the top pick for companies that run their systems on the cloud.
Automation
Regarding automation, IMHO any tool you learn will be good. There are different tools for automation but most of them do the same type of job. The winner in this case is Ansible followed closely by Puppet.
Containerization
Another major winner(s) here. The duo Docker + Kubernetes is always mentioned on the skills requirements that companies want for a DevOps / SRE role. It’s almost like container is a synonym of Docker. And of course, you need something to manage your myriad of containers. Here it comes Kubernetes to help you with that.
CI / CD — Continuous Integration / Continuous Deployment
Continuing with the big winners here is another one: Jenkins When it comes to CI / CD this is THE guy. It’s the leading Open Source automation server and provides hundreds of plugins to support building, deploying and automating any project. I prefer to use GitLab CI solution but the good thing is that on CI/CD space you have a bunch of options to choose.
Monitoring
On the monitoring field, I was a little bit surprised on Nagios becoming the most requested tool. But I didn’t work with Nagios for a long time so maybe I was expecting a new player to stand out. Maybe this new player is New Relic or Datadog. My conclusion is: if you become proficient in one of those monitoring tools you will be good to go and apply for any DevOps / SRE job. If the company uses another tool you should be able to learn faster because they are very similar.
Logging
Not many job descriptions mention logging tools. Those who mention points out Splunk or ELK (ElasticSearch, Logstash, Kibana). I think if you choose either one you will be well served.
Databases
It was very interesting to discover that most of the companies don’t really specify which database you have to know. Some of them (very few) point out to PostgreSQL or MySQL when talking about relational databases and some of them point out to MongoDB when they are talking about NoSQL databases.
Operating Systems
No graph here because the choice is ALMOST unanimous. Linux is THE operating system you must know. And not in a superficial way. Most of the jobs demand that you know deep system (Linux) internals. So push yourself beyond the simple commands. Learn how to use Linux tools like tcpdump, netstat, iptables, uptime, dmesg, perf, ss, strace and so on…
Other (Generic) Skills
I decided to call it “generic” because they don’t fit in any of the categories above. It doesn’t mean they are dispensable. No way. They are a MUST have.
Distributed Systems
- Microservices
- Concurrency
- Multi-threading
- Large scale storage systems
- Caching and its tools like Memcache, Varnish, Redis
You need to have all of those concepts above inside your brain. You will use them daily.
Conclusion
This may be a very simple research but it shows (at least for me) a pattern when companies want to hire some DevOps / SRE. I decided to do this to help me focus on which technologies I must learn in order to improve my DevOps / SRE skills. It’s very easy to lose focus when you are trying to learn something.  You can get so saturated with so much information and be paralysed. Occasionally I struggle with that. Please be careful. Analysis Paralysis is a very bad “disease”. If you want to follow these same patterns and learn what companies are demanding to feel free to do that. I hope this simple research help you to move on and choose what is best for you to learn or start learning.
