Ok, cool, now that you've read it, I'm sure it's something many of you have encountered—user says that they restarted something, but clearly they didn't. Made me think that in the current era where smartphones with cameras are so ubiquitous, a way to verify that the device in question actually had power would be to have the client take a photo of it and send that to you. Then you could know if A.) they were looking at the right device and B.) the power lights were really on.

Think it'd work? You ever try anything like that? Oh, and if you've got a similar SysAdmin tale, be sure to go comment on that same post!

Looking at professional certifications? I've discovered that community colleges near me offer Adobe, Microsoft and CompTIA certification exams free of charge! You might find an academic testing center near you that does the same or offers a great discount. Considering these exams usually cost $150-200 when administered by private testing centers? Woot!

There's been a lot of discussion lately about Net Neutrality and the various pros/cons. While I'm loath to have unnecessary legislation or "solutions in search of a problem" and greatly respect those viewpoints of the debate, I've ultimately fallen on the side in favor of Net Neutrality. Nilay Patel over at The Verge pulls no punches in his eloquent article that highlights so many of the reasons that have shaped my view on the issue.

It's a long read, but well worth it. This sort of thing impacts all of us in IT and no matter what happens or what opinions you hold on the matter, I'm hopeful we can all find common ground in keeping the internet great.

Hey Jim on the off topic concerns, we are seeing an increase in traffic overall based on our efforts. See more information here

I looked at the stats for the My SQL Server topic and the questions asked, excluding deleted, were up year over year for April and May but saw a decline in June. I'll see if I can find further indications why this is the case.

One thing I use that you may find useful is Google Trends. It can help you see how in general search terms are trending.

(reading for the first time)  Nice article.  Gotta like that action.  I suppose it's difficult to interpret results and do a cause-and-effect to what EE initiative led to the increase(s) in volume.    

It was very unexpected when Gene agreed to sponsor my SQL Saturday last year, to include free memberships, and was disappointed when that didn't translate to signups.  Perhaps I need to rattle a few cages in my local SQL community.

One thing I never really understood (keep in mind I'm not an SEO guy) is why tags were discontinued from articles in place of the question title.  Last year I tried doing a Google search for keywords that should have resulted in my articles in the search results (SQL Server GROUP BY, SQL Server CASE, etc.) and results were not that hot.  

For some reason my two Requirements Document Template articles get significantly higher views then the other articles.   Maybe I just nailed the title correctly.  A Google search for 'requirement document template reporting' shows my article as #2.

Which Database Choose?

This Article about choose the NOSQL database based on application requirement. Different NoSQL DB’s available, there are three primary concerns you must balance when choosing a data management system: consistency, availability, and partition tolerance.

 

* Consistency means that each client always has the same view of the data. * Availability means that all clients can always read and write.

* Partition tolerance means that the system works well across physical network partitions.

 

Chose the Database system based on your application requirement.

 Example Comparing MongoDB and CouchDB.

As you can see in the diagram, MongoDB and CouchDB are built with a slightly different focus. Both scale across multiple nodes easily, but MongoDB favours consistency while CouchDB favours availability.

In the MongoDB replication model, a group of database nodes host the same data set and are defined as a Replica set. One of the nodes in the set will act as primary and the others will be secondary nodes. The primary node is used for all write operations, and by default all read operations as well. This means that replica sets provide strict consistency. Replication is used to provide redundancy - to recover from hardware failure or service interruptions.

CouchDB uses a replication model called Eventual consistency. In this system, clients can write data to one node of the database without waiting for other nodes to come into agreement. The …

          Whoa, whoa, whoa... Apparently in West Virginia, being a State Senator is a part time job. Which means that a State Senator likely has to work a normal, private-sector job. A job for a company that might have a strong opinion about a particular vote. A company that then might fire the State Senator after they voted in a way the company didn't like... Uh... Conflict of interest much?

          What do you think? Is this system broken? How would you fix this?

          There's very few employers that would allow someone to be gone for six months of the year and only work half time the other six months, which is the normal time demands of a Minnesota state legislator, so I’m having a hard time imagining what these part-time legislators would do for a career.     When I was in the Army National Guard employers didn't even care for me being gone one weekend a month and two weeks a year.

          At those salaries I'm surprised we don't hear more stories about bribery, corruption, and employer conflict of interest.

          As a side note when Jesse 'The Body' Ventura was governor he frequently refereed pro wrestling matches.  No conflict of interest there as I don't think it would affect the state if 'Bruno the Midnight Stalker' or 'The Bushwackers' won.   I still think it would have been great if he hired Axe and Slash as his state budget directors.

          What this means to you: If Net Neutrality is repealed then your ISP chooses which sites load fast and which ones don't. Example: If your ISP is Comcast or Charter they could make sites for Dish Network, Directv, Netflix, or Hulu run slow as they are competitors to your ISP. With a 2 to 1 person lead the Republican controlled FCC the REPEAL is expected to pass. DO NOT ALLOW THIS TO HAPPEN! Contact the FCC at 888-225-5322 and complain a lot or your ISP will decide for you what sites you see, how quickly you see them, and if you see them at all!

          IF you complain online by filling out a form with your name, address, and email that information will become PUBLIC KNOWLEDGE!

          The world has now had time to recover and mitigate damage from the widespread WannaCry ransomware attack. We evaluated what it has left in its wake. Tallied damage includes:
           
          More than 150 countries.
          Currently $111,996.86 has been paid in bitcoin so far to decrypt files.
          Around 16 of England’s National Health System organizations affected, with doctors resorting to pen and paper to complete patient records.
          Renault, a European auto manufacturer, kept a French plant—that employs 3500 people—closed Monday, May 28th as a “preventative” measure.
