Most software companies run in that dilemma. In order to write software that works, you want to write some tests. The question for many of these companies is: what kind of tests are most efficient for my business?
Here we talk about seven common test practices in the software industry.
Probably the most used form of testing is Unit Testing. This is easy to write and very effective in discovering bugs. If you are looking at verifying correctness, this is 100% what you need to have to test your software.
In most cases, Unit ...
Developers can choose from many advanced software applications in today’s environment of intensive research on potential uses for blockchain technology. Web development tools include Ethereum DApps Development where researchers and developers strive to build decentralized apps and smart contracts. Smart contracts have the built-in ability to adjust based on changes to key terms and to monitor compliance with the terms of the contract.
Blockchain development tools help to facilitate software development. If a developer is new to blockchain or lacks experience, he or she should become ...

SECURITY WARNING
Before installing Docker and containers with services on your Linux system, make sure to read and understand the risks as mentioned on this Docker and iptables page. Especially, Docker will make all your containers visible to the entire world through your Internet connection. This is great if you want to indeed share that service with the rest of the world, it's very dangerous if you are working on that container service since it could have security issues that need patching and such. Docker documents a way to prevent that behavior by adding the following rule to your firewall:
iptables -I DOCKER-USER -i eth0 ! -s 192.168.1.0/24 -j DROP
This means that unless the IP address matches 192.168.1.0/24, the access is refused. The `eth0` interface name should be replaced with the interface name you use as the external ethernet connection. During development, you should always have such a rule.
That has not worked at all for me because my local network includes many other computers on my LAN and this rule blocks them all. So really not a useful idea.
Instead, I created my own entries based on some other characteristics. That includes the following lines in my firewall file:
*filter :DOCKER-USER - [0:0] -A DOCKER-USER -j early_forward -A DOCKER-USER -i eno1 -p tcp -m conntrack --ctorigdstport 80 --ctdir ORIGINAL -j DROP -A DOCKER-USER -i eno1 -p tcp -m conntrack --ctorigdstport 8080 --ctdir ORIGINAL -j DROP -A DOCKER-USER -i eno1 -p tcp -m conntrack --ctorigdstport 8081 --ctdir ORIGINAL -j DROP
My early_forward allows my LAN to continue to work. These are my firewall rules that allow my LAN computers to have their traffic forwarded as expected.
Then I have three rules that block port 80, 8080, and 8081 from Docker.
Docker will add new rules that will appear after (albeit not within the DOCKER-USER list) and will open ports for whatever necessary service you install in your Dockers.
Note that the only ports you have to block are ports that Docker will share and that you have otherwise open on your main server. If Docker opens port 5000 and your firewall does not allow connections to port 5000 from the outside, then you're already safe. On my end I have Apache running so as a result I block quite usual HTTP ports from Docker.
As we are helping various customers, we encounter new technologies.
In the old days, we used chroot to create a separate environment where you could have your own installation and prevent the software from within that environment access to everything on your computer. This is particularly useful for publicly facing services liek Apache, Bind, etc.
Today, BusinessWire disclosed the fact that they and their customers were benefiting from the changes made by Google to improve the giant search engine results.
The news is not that surprising since the Panda change was to eliminate most of the so called farmer websites. Websites that would copy news, most often as is, and not themselves create any additional value (Except to the owner by having advertising and other products and services for sale on their otherwise fairly useless website.)
Of course, many people are not happy as this change affected 11.8% of the US websites. Yet, users will ...
That's it! The phone commissioners have finally decided that it's OK for telemarketers to call cell phones and try to sell you their products and services.
Personally, I do not think that, in itself, it is a bad thing... except that if I receive even just 1 call a day and have to spend 1 minute each time, I will be burning 30 minutes a month for nothing. (Okay, with 1,000 minutes a month, it wouldn't matter that much, but that's like text messaging... if you receive spam via your phone and you have to pay 20 cents for each spam email you receive, the bill goes up quickly ...
Watching the spiraling price of gold (the spot price as of this writing is $1,213.40/oz) has been a humbling experience for me. There are all kinds of marketing forces happening to cause this, but if you follow what the Austrian School folks are saying, this is not a surprising trend at all. Central banks around the world are dumping their U.S. dollars and buying up gold, which is driving the price up. But I think this is different than just another commodity bubble, because the way gold is perceived--as a store of wealth. Traditionally investors who feel the currency they are in is threatened ...
