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 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.

Hi some one hacked my joomla site,
I am not able to access to "administrator/index.php?option=com_config", it is giving 404 error.
The hacker is "hacked by s13doeL", he added "joomla.class.php and index.old.php" in all over the web files.
I think there is only one solution, reistall everything.
Could someone help to migrate from 1.5.18 to 1.5.20. I do not want to change to 2.5 because that template is not supported to 2.5.
Is it just enough copy all database and then link to it? Does it copy all old articles? or do I have to copy ann manualy?
Sorry to say this but it's really your own fault. Not only are you using an unsupported version of Joomla, but an old version in that series as well. The latest version of the Joomla 1.5 series is 1.5.26 so there should be no reason why you weren't using that.
I answered a question regarding being hacked and gave some advice along with recommended extensions to use. The guy was using Joomla 2.5 but it can still apply to Joomla 1.5.
Joomla! 2.5.4 Hacked: Having trouble with diagnosis
So remember, in future, keep up to date else it's to your detriment.
Update:
To upgrade from Joomla 1.5 to 2.5, install this extension. This will update the core Joomla stuff and database tables. Do bare in mind that it will not upgrade 3rd party extensions, therefore you will need to upload the 2.5 compatible versions yourself.

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.

I have used codeigniter for few of my projects in my portfolio and currently seeking a job opportunities. However, I heard yii is a very nice and high demanded php framework in the market now. Is that true? Should I turn my attention to yii or keep building more codeigniter projects in my portfolio for my first web developer job? Thanks for the help.
Well this does not fit here but what i have learned that since 4-5 months industry here have started working on Yii. I have been working on Yii since 4 months it is easy and supports Rapid Application Development.
Moreover performance may be key factor but to me its time to development that this framework allows you. I have worked on CI but Yii is far more ahead of that. provides you nice JQuery implemenation does Ajax validations for you and much more.
I recommend it 100%.
If you see what is in market you may not be able to learn whole things and some how things keep changing once COBOL was famous but now........... so basically on everything I guess factor overrides is Ease and Rapid Application Developement these are provided by Yii

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.
