I use go1.14.11 in my product environment, it works fine until now.
But there have been so many versions after 1.14.11, most of them have some security fixes.
I wonder if I need to upgrade to the newest version of Go? Is there any big problem if I keep with go1.14.11?
The Go team supports the last two major versions. At the time of writing those are 1.16 and 1.15.
This means 1.14 does not receive security patches anymore and you should upgrade. Note that Go has a very strict backward compatibility policy, so upgrading is easy.
Is there any big problem if I keep with go1.14.11?
Yes. The Go team maintains and releases security updates for the 2 latest major versions, which currently are 1.16 and 1.15. There are no updates to 1.14 released anymore.
This means if you've built your app using Go 1.14 and a security bug is discovered in its code, your app will be vulnerable to it. You can only get protection for those newly discovered bugs if they get fixed in the Go SDK and you rebuild your app with a version that contains that fix. And as mentioned above, that can only be any of the supported version, that is, any of Go 1.16 or 1.15.
Beyond the security fixes, newer versions of Go tend to be faster. So using newer versions you often get better performance (faster apps) just by using them, without improving / optimizing anything in your app. There is no reason not to use the latest version available at any time.

I have been using R Studio 0.98.983 in Debian Wheezy until yesterday. But today, when I opened R Studio it complains saying that couldn't find the .Rproject file and afterwards when I browse the files through the file panel all the files are grayed out and I cannot load anything.
I went to the official website to download a new version and it is just for Debian Jessie (and it doesn't work at all in Debian Wheezy. All the UI elements are in blank). In addition, R Studio cannot be found anymore in the Wheezy repositories.
I'm getting the impression that R Studio guys are getting Windowized in the sense that they are pushing people to move to the latest version of the OS. For those that we use computers to work (and not just to play), we trust more an old last stable version than a new buggy fashionable version of anything with which we have to spend hours figuring out how to make thinks work again. It's really a pity.
Any suggestions? Is there any working alternative to R Studio?
Thanks in advance.
We do in fact do our best to preserve backwards compatibility. Unfortunately, the newest release (0.99) builds on Qt 5.4, which requires a glibc newer than is present on Jessie. If you can't upgrade your glibc, then you can install an older RStudio build (try 0.98.1103):

We've heard that Qt is considering restoring compatibility with older glibc in an upcoming release, so hopefully we can too.

I was wondering if it is safe to upgrade to OS X Yosemite today when they release the official version?
Yosemite Stable version at Apple
The most important tool I need working is Homebrew (nginx,php etc)
Will those packages continue to work, or will it most likely break and be unsupported for a while?
Thanks.
As I understand it, a bunch of people I know using Yosemite GM and homebrew have not seen any new issues arise. I do hear about general performance improvements under Yosemite, so that sounds promising. The mobile devs in my office also seem to like it, but they mostly just use XCODE, so that may not apply to you. As always, make sure to backup your machine before the upgrade, and test your tools thoroughly once finished.
Homebrew's (cautious) advice is to wait for a week or two if you really need your machine to work, though people have been using Homebrew with the betas and hammering through problems with popular packages. There is a list of things in Homebrew core that are still broken on 10.10 here: https://github.com/Homebrew/homebrew/issues/29988 -- though the php and nginx formulas are not in core, so I can't advise on those.

We have already Joomla´s version 1.5.14 from 2009 to make our homepage setting. Now we want to upgrade the version to 3.0.
We have made a test page 3.0 and compared it with our original page. We understand that files and the database have been subject to changes, so it´s difficult for us to see how we can practically move our data to the new version.
We have discovered that with regard to the version 1.7 it is pretty easy to upgrade to the new version. We have studied your Joomla manual, but we still have problems to get it right. Have you ever yourselves tried to upgrade a similar situation?
Can you possibly give us some hints how to do it?
It would help us if you could suggest the steps you want us to take?
You now, it´s not so nice to go through a huge number of manual pages.
As you can appreciate I have taken back-up on the data base and the files. I´ve come that far and need your help to proceed further.
Fear not, upgrading from Joomla 1.5 to 3.0 isn't hard at all. There are 2 really good extensions that allow you to do this:
jUpgrade and SP Upgrade.
Both allow you to upgrade to either Joomla 2.5 or 3.0
I would first recommend updating to the latest release of the 1.5 series (1.5.26) before using one of the extensions. To do this, simply download this package, upload to the root of your Joomla site in the FTP and extract it.
May I just point out that Joomla 2.5 is still the recommended version to use as it is the long term version, where as Joomla 3.0 is short term till Joomla 3.5 is released.

A client has an old version of Magento (1.2.0.3). Can I upgrade directly to (1.6.1.0) or do I have to go through a progressive series of upgrades to make it work.
Generally I think it's better to do progressive updates. It's also better to keep up with new versions and don't let clients fall behind too much. Consider offering them a maintenance contract for a monthly fee or a fee per upgrade.
The biggest changes are between version 1.3 and 1.4 where the Magento team has done a fairly large overhaul of all templates by optimizing the HTML and renaming CSS class names. So it will also depends on how much customization has been done to the site's theme. I've just completed a 1.3.x upgrade to 1.4.2 which took be about 100 hours. This is long for such an upgrade but I've also done a lot of clean up work as the 1.3.x version was not very well built (by another web agency).
The website is now much more upgrade proof and upgrading to 1.5.x and 1.6.x is now a fairly straight forward job taking probably just a couple of days.
Go for progressive and turn off any modifications
and use default template. backup each upgrade step

I see some softwares are being developed more than one version at a time. Ex: Google chrome 15 is being developed when version 14 is still in Beta, Firefox 4 and 5 is being developed together. I wonder how could that be possible? What if there is a bug found in Chrome 14, does the team work on version 15 have to fix that bug again? Isn't working on just one version at a time would be more efficient and consistent?
By using a source code control system such as Subversion, Git, Mercurial, etc. you can manage multiple branches of your code, and merge edits from one branch to another quite easily.
Branches are often used to maintain a current stable version of a product, in which you fix bugs but don't add major features, and a development version to which you add new features.
During the development of the new features branch, you periodically merge the bugfixes from the stable branch into it. The source control system automates that merge process to a large extent.
