Informal intro.to Version Control Systems

•

0 likes•187 views

I made this as an attempt to familiarise my team members with the concept of a version control system. Their are not many commands and technical details. My goal was to sell them on the point that it is an effective and easy to use collaboration tool - and is just so darn cool!

Software

Motivation
Scott Hanselman
(www.hanselman.com)
“There are a finite number of
keystrokes left in your hands
before you die”

Agenda
• What is “Version”
• The “Pain”
• The “Aspirin” – a VCS
• What’s in the box ?
• Ok..! But how do I use it ?
• Conclusion

What is “Version” ?
“Difference of contents of a file at two different times”
Different content, Different version

The “Pain”
• No way of knowing which lines of code have changed
since last hour ?
• Who changed the code and why ?
• How do I get the old code back ? Delete all the newly
added lines manually ?

…and a bit more “Pain”
• The inconvenience of sending files through Emails,
Dropbox, blah blah blah…
• Want to add an experimental feature?
Code base at risk!
• No issue tracking; “Yaar masla to tha kahiN… par yaad
ni arha!”

The “Aspirin”
Q: What is a VCS?
A: Simply, a system that solves above problems and more.
Q: Ok, I need VCS. But ermm… Which one?
A: GitHub FTW!
Q: Now what is GitHub?
A: VCS platform based on Git, excellent for
social coding.
Q: Umm... What is “Git”? OTL
A: Glad you asked! Git is the best VCS. It has a
CLI, and was created by Linus Torvalds . I am just that awesome

“Read instructions before use”
• How it works ?
• “Ray-pozi-tory”?
Repository = Your Files
+ Project Version History
+ Git Data

How does it help me ?
• See exactly “what” was changed and “where”.

How does it help me?
• Know who changed what, and why ?
• Revert to older code base? Easy!
Just ‘Pull in’ the older commit! One click!
Tight Integration with IDEs. (not Turbo C of course)

How does it help me?
• “One Click to Update them all!” no need sending files
• Want to add a feature? Use branching.
• Code is separate until you merge!

How does it help me?
• Fantastic Issue tracking
• Comments attached to code lines

How does it help me?
• Comment on issues

Conclusion
• VCS is a tool; use it wisely
• Get a hang of it, it’s great!
• Happy Coding and Committing
Thank You!

We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.

Modeling languages are generally applied for developing systems and software – both internally, with domain-specific languages, and with standardized languages targeting a general purpose and a wide audience. Way too often these languages are weakly created and defined leading to poor quality: Language definitions tend to contain errors and inconsistencies; notations do not recognize the communication and problem-solving needs of humans; standardization organizations push exchange formats that do not fully work and offer certificates that do not measure mastery of the language. We describe common problems in language development and point them out with examples from known cases. To overcome these problems, we suggest several solutions to improve language development, including using modeling languages specifically designed to define modeling languages, continuous testing and prototyping, and keeping language users in the loop.

All women want one thing the most in life to be love and love in return – not much to ask. A lady wants a good man who loves you unconditionally and loyally.

And you don’t think it’s asking too much to want to be with a loving, intelligent man with a good sense of humour and daring, an upright and confident man – who knows who he is. No one wants a chauvinistic and macho man, but you do want someone who will be willing to protect and care for you. Who loves you for you and not some kind of imaginary. You have no doubt that when the right guy appears on your doorstep, you’ll never let him go. But sometimes a man doesn’t realize he has that good woman.

Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
