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 ...

If you are downloading software online, are you taking the proper precautions to ensure your safety? You may be tempted to find links for downloading programs that cost a lot, but there is always the danger of exposing yourself to malware and data theft. It's possible to keep yourself safe from these risks while scrolling for the programs you need. You just have to know exactly what it takes to beef up your defenses when you are downloading a PC game or graphics design software. Here are a few tips to keep in mind:

1. Check if the website is trusted

The first thing you will need to ...

What is a Queue

In software a queue is a container which is used to add items on one side and remove them on the other in a very efficient manner.

Sorted Queues

When used by a Journal, a queue is often going to support some kind of sorted order. Some jobs are more important than others and these should be built sooner. In other words, we give those jobs a higher priority and we sort the queue by priority first then using the time at which the job gets inserted.

Note that the C++ std::queue and std::unque containers do not offer anyway to support a priority. Instead you have to use ...

In the last few days, we started hearing about a massive bug in the implementation of the VM memory handling.

Intel has been frantically working on fixing host machines kernels in order to prevent one VM from accessing the memory of other VMs that run on the same machine.

Of course, most users are not going to attempt to read someone else memory so in that sense, most of us are relatively safe. But all of those who are not so lucky and have uninvited guests on their systems are running at very high risk. The information available from Intel says the memory is accessible only in Read mode. ...

A few days ago the news that SSLv3 was no good came out. The protocol allows for patterns that can be used by a hacker to decipher an encrypted message without the need for the private key. In other words, encryption using SSLv3 is no good (anymore--it never was, but we know this only now.)

We fixed our Apache2 settings, for those interested, you just have to turn off SSLv3 with the following setting:

SSLProtocol all -SSLv2 -SSLv3

Although to really remove all the encryption methods that are not that secure (can easily be cracked) you also want to change the list of ciphers with:

The Protected Nodes offers some additional supports to views 2.x and 3.x in Drupal 6.x.

The additional support includes fields, filters, and sort capabilities that are added to the Node type. The join between the regular node and the protected node data is the node identifier (nid). This means the revision identifier is ignored.

• Password last changed
  
  This value is the date when the password was last modified. You can display this date, filter using the date, and sort by date.
   
• Node is protected
  
  This value is a yes/no value (i.e. Boolean) which can be ...

Version 7.x

Version 7.x-1.x-dev is a starting point... It is not complete, although it shows you a functional Management menu as a dropdown. More to come as time allows... See issue [#791664] for more info.

Version 6.x

Version 6.x-1.13 fixes the vertical menu problem which had to do with CSS caching getting lost.

Version 6.x-1.10 to 6.x-1.12 fixes the non-called theme() function versus the other sub-modules that have callbacks through the theme() calls. However, we really need to have callbacks instead. Added horizontal and vertical themes. Attempts to fix to the vertical menu problem

Interestingly enough, today I received a Security Advisory from Drupal saying that users received an email from a hacker asking them to install a Trojan module on their Drupal system.

I find it quite interesting since, if Drupal wasn't secure, the hackers would not have to ask you to make it unsecure, would they?

However, this shows how many CMS systems introduce a security issue problem to your web server installation since it is required to let your web server execute any one PHP file...

All the files installed on your web server and that are directly accessible from the outside (i.e. ...

Security Issue

A security issue was found in all versions of jsMath before 2.x-dev for Drupal 6.x of Jul 29, 2010.

You may still securely use older versions of jsMath on private websites and websites were you are the only user (as in, the only one who can log in.)

The Drupal Security Advisory issue is here: https://www.drupal.org/node/854402

Other Problem

There is another problem: jsMath offers a JavaScript function that parses entire web pages (although there are ways to circumvent that problem, the module does not currently make use of those.) The jsMath Drupal module uses the ...

SimpleMenu Disappears

There following are a few of the main reasons why SimpleMenu disappears.

Pop-up Windows

By default, SimpleMenu wants to hide itself in pop-up windows. This is a feature.

The reason is that many websites will open pop-up windows for all kinds of extra-features such as uploading an image or printing some description of an image or the definition of a word or product.

These windows should not include the SimpleMenu bar.

There is a dedicated page giving several different ways to fix this problem on your website.

Menu Overflow

Very long menus will disappear on the
