I am a bit confused about Docker and how can I use it. My situation is the following:
I have a project that requires the use of a requisite, in my case installing ROS2. I have installed it in my system and develop a program. No problem there.
I wish to upload it to Gitlab and use CICD there. So I am guessing I will push it to my repository and then build a pipeline where I can use as image the docker image for ROS 2. I haven't tried it yet (will do it tomorrow) but I guess that is how I should do it.
My question is, can I do something similar (or how to ) in my local machine? In other words, just use the docker image and then develop and build over there and not install the requisite in the first place?
I heartily agree that using docker to develop locally improves the development experience, primarily by obviating system specific dependency management, just as you say.
Exactly how this is done depends on how many components you need to develop simultaneously, and how you want the development environment to behave .
An obvious place to start might be docker compose, a framework for starting multiple docker containers. https://docs.docker.com/compose/gettingstarted/ looks like quite a nice tutorial on the subject, and straight from the horse's mouth too.
However, your robotics project (?) may not be a very good fit for the server/client model behind the write - restart python - execute client - debug - repeat cycle in the document. To provide a better answer, we'd need a lot more understanding of how exactly your local development works - what exactly you want your development process to look like in this project might require a different solution. So add some workflow details to your question!
I'm using Windows, Mac and Linux machines in my daily duties. On all machines, I program in C++ and various shells scripts. So far I've adopted the various "main" IDEs on each platform, but the diversity is irritating. I'm therefore looking into the possibility of using Sublilme Text on all platforms.
I have a setup of Sublime Text on Windows that works perfectly and would like to use the same on the other platforms also, so that when I change something in my Sublime setup on, say, my Mac, I can easily pick up the latest setup on my Windows machine the next time I'm there.
Is this possible on the 3 mentioned platforms, without getting (more) grey hair? If so, any suggestions or experiences thereof?
Many folks upload the "Packages/User" folder to GitHub (or your VCS service of choice). Then, they use Package Control to install their packages. Package control, through a settings file, will install any missing packages on a particular machine. I wrote a bit more about it here. You would then clone the git repo onto each machine, pulling updates when you decide to change something.
Alternatively, you could probably use a cloud service + symlinks to keep things auto synced, but I've personally never used it that way.
There are some plugins that are platform specific, so keep an eye out for those.
There's also the Package Package Syncing, which syncs installed packages and settings via some cloud service.
Works quite nicely, and automatically.
Has the advantage that you don't have to push/pull some dotfiles repo all the time.
No idea though whether this will work seamlessly across platforms (meaning whether all the settings will be platform-independent).
I need to integrate a CI(continues integration)+CD(continuous deployment) tool for my ruby on rails application.
It would be great if it has the following features.
Code metric tool like (metric_fu)
Gitlab,Gitlub for repository managements.
Following are the list of CI tool I'm consider.
https://travis-ci.org/
https://circleci.com/
https://www.shippable.com/
https://www.codeship.io/
https://wiki.jenkins-ci.org
http://cruisecontrolrb.thoughtworks.com/
https://drone.io/
​please help me to compare the feature of these CI tools......
(full disclosure, I work for ThoughtWorks)
I'd replace CruiseControl.rb with http://www.go.cd/ or http://snap-ci.com - ThoughtWorks isn't actively updating CruiseControl.rb since Go CD came out several years ago. Both of the newer tools (also from TW) are designed with CD at their core.
To the main part of your question - With any of the tools you mentioned I'd recommend calling the code metrics tool of your choice as one of the stages, and not relying on the CI/CD tool to have that knowledge natively. Generally speaking, CI/CD servers are used to orchestrate a process that relies on several other tools like build systems, metrics tools, testing tools etc.
Magnum CI should be great for what you need.
It also deploys to Heroku, which hosts Rails apps. So if you want it to run some tests then deploy automatically, it sounds like it could be a good fit!
I found magnum-ci.com recently and feel it suites my entire need.
Hope this may help ROR enthusiastic...
STS is over 350MB and most of it is corporate blubber ware that I do not need. For example its default installation includes bunch of Servers that shows up in project explorer and other things related to VMware cloud related products. All I need is Grails and Groovy and JavaScript related development and nothing else.
What is the procedure to remove all these things for clean and light installation of STS without destabilizing STS?
You can choose not to install tc server, Spring Roo and Apache Maven during the install. Also, you can go under Help -> About SpringSource Tool Suite, click Installation Details..., and uninstall plugins you don't want.
I know this question is already answered, but I just wanted to mention another way of installiong STS. You can do this through update sites. This way is slightly more complicated (only slightly), but does have the smallest footprint. You can see the instructions here:

Searching with '[Delphi] "source control"' didn't return much, so here goes: For those of you Delphi programmers working on your own, what source control do you like? I know about TortoiseSVN (which can be used without a server), but I'd like to know if there are better options before choosing it.
Thank you.
SVN will be more than enough as you'll mostly use it for backing up and diff'ing versions.
You can use VisualSVN Server and TortoiseSVN with Delphi IDE Integration. All of these are freeware. If you wish to use any other freeware SCM with Delphi IDE integration you'll need to buy SourceConneXion or Athlant. Also, if you're using D2009 you'll need to convert strings to ansistrings in order to get TortoiseSVN addon for delphi to work.
I use Mercurial, and have used Bazaar and Perforce (free for small teams). All are good, but nowadays I tend to prefer Mercurial. Mercurial comes with its own tortoise
which, while not quite as polished as TortoiseSVN, is perfectly usable:
(source: sourceforge.net)
For users of RAD Studio XE or XE2, Uwe Schuster has published an IDE add-on called Version Insight Plus that adds Mercurial and Git support to the IDE's built in version control support.
For all the systems I have mentioned, no central server is required.
I would recommend Git which is free & open source and:
Doesn't require you to even set a central server even if you want add more developers or machines.
Is Extremely Fast (imo)
Encourages the use of branches
I use it for almost every new project, even when it's just me on the project. It's an extremely fast distributed version control system and was written by Linus Torvalds and is now used in high profile projects like the Linux Kernel and Ruby on Rails.
Git isn't hard to use from the Command line but also has it's own "Tortoise" package (TortoiseGit - albeit not as polished as it's SVN cousin).
SourceGear Vault is free for a single user. I like to use the external client because I work in different environments, but If you want Delphi IDE integration, you can use Source ConneXion (not free).
You might look at some of the responses here (Stack Overflow) if you do have Delphi in mind. As mentioned in the answers there, I use Team Coherence which integrates very nicely with Delphi's IDE, and is aware of Delphi file groups (.pas with .dfm etc). I think it's written in Delphi too.
Having said that, the other comments already made are true - you shouldn't really let your choice of language dictate your choice of VCS.
Even though you've said single user, I would look for a solution that allows you to easily host it on a server/other desktop machine, so you have separated your development machine from your source repository. I'm probably teaching granny to suck eggs but you ought to check that whatever you choose can be easily backed-up too (even to a USB key or external drive would be fine). :-)
I know you have asked for Source Control, but if you are always planning to be a 'single developer' you might like to consider an automatic backup solution like AJC Active Backup instead. Yes, you lose the ability to check in and out specific versions, but at the same time you avoid the need to check stuff in and out all the time when it is only you working on a project. And you can recover or diff any previous source files by date for as far back as you care to configure. It's very much a set-and-forget solution, until you need to recover something, when it is invaluable. And the archive itself can be backed up in the normal way.
I use TortoiseSVN, but store my repositories as files on my laptop (on a share that can be accessed by mutilple VMs), not managed by a server. This means that I have full access to the repository regardless of server access, but also allows me to easily backup the repositories to the company file server when connected.
Since I am the only programmer I have not needed a separate server so far. I have seen Nick Hodges (Delphi Development Manager) say very nice things about VisualSVN Server, and I aim to check this out, to see how easy it is to backup/restore the repository: if that can be automated, and done very quickly, then I will probably adopt that.
Longer term I am going to look at the various flavours of distributed VCS, as that may be better suited to multiple laptop-based developers; I'm not sure yet, as I've not reached that page of my to-do list ;-)
One of the things supposedly in the pipeline for Delphi is integrated support for VCS. I've no details on that, or on any implications for current users of the various traditional or distributed VCS.
The language you use doesn't really matter in the choice of the SCM you will use.
It can matter if your favorite IDE supports or not this SCM.
TortoiseSVN is just a svn client, if you choose svn you can have several client.
I use Tortoise, and subclipse for committing in the same svn repository.
I would suggest using SVN server on a separate machine (either VisualSVN as suggested before or CollabNET Subversion Server) and TortoiseSVN with JVCL integration expert (also as suggested before).
Besides getting all the good stuff from the version control, you'll also automatically have backup on a different computer, which is always a good thing.
I know this will get down voted, but I feel it has to be said.
I've used Version Control software for many years at my job, and it is required when multiple people work together - to make absolutely sure that no two people overwrite one-another's work.
But for my personal development at home I don't use one. I find them overbearing and inconvenient for a simple one-person project. And I've tried several packages including Source Gear Vault and some others that other people have mentioned.
What I do instead is at every significant change to my program that I might want to go back to, I make a copy of the entire program directory. If I screw up in the next change, I can go back to the copied directory.
I also permanently keep copies of all my directories of every release of my program. If I ever need to do comparisons between my current version and previous releases, or between two different previous releases, I use Beyond Compare by Scooter Software - a simply great tool for diff-ing and copying changes between versions. If you use Source Control software, Beyond Compare will integrate into it nicely.
So I mention this simply because I have often heard everyone pushing Version Control Software, even for the individual developer. For some of us, it's overkill.
You may want to consider this simpler solution.
I use Bazaar with Delphi and it works well, especially for solo developer workflows. It has it's own TortoiseBzr but it isn't as good as some of its cousins so I recommnend the excellent Bazaar Explorer instead. One of the great things about Bazaar is it's flexibility and the ease with which you can change workflow or include another developer in a project that started off solo.
A lot of articles about Bazaar will tell you it is a lot slower than Git or Mercurial. They are out of date, now it takes a similar time to acomplish operations as they do and is faster on some operations.
My team use StarTeam and I have never used something else like SVN so it is hard for me to do a good compare. Starteam has both positive and negative sides.
Pros:
You can register Change requests and
connect them to checkins. This make
changes more trackable.
I feel more comfortable with a real GUI compared to commandline or some Shell
extension.
Cons:
Expensive, as most products from
Borland...
Latest version use Java. It is almost like the previous Win32 version and they have added more features, but I still feel that it is some slower and more memory hungry than before.
GUI could be a bit more intuitive.
I'm not big on version control, but use SVN/Tortoise and am quite happy with it. The main benefits that I see for a single developer is being able check out older versions of the application, and use multiple computers for development (desktop / laptop) - other than the obvious backup benefit. I tend to not need it for diffing files, as I find the version control tools within the Delphi IDE fairly good for this - provided the "bug" was introduced recently.
I think most Delphi developers use SVN/Tortoise (making it a fairly safe choice) - but there are trendyer options such as Mercurial and Git.
As a single developer, I have used Perforce for a number of years. It has been great. Aside from a CLI, you can use the P4V client. There's also an explorer plugin available, as well as Delphi IDE integration. I actually just found this free integration on Torry yesterday:
p4delphi
I've installed it in Delphi 2010, and it works pretty good.
Perforce is free for two user, it would require you to install perforce server, but the server footprint is very, very small. you can use P4V (Perforce visual client) which is far more convenient than tortoise, it also provide Windows explorer extension to be have just as tortoise (but you could skip this installation). Delphi integration could be done using P4Delphi.
I am using subversion, bug tracking and simple to use project planning for my latest delphi project from an web service provider. http://www.unfuddle.com has a free account for projects less than 200mb with 1-2 developers and the user interface is easy to use.
