Software developers unproductive because emails?

When researching the web when an article about a business consultant I have fallen into the hands, which caused me to frown.

This has specializes in IT companies, particularly software developers Housing and reported in the article about optimization potential in the software development.

35% of software developers capacities, he claims, are thereby squandered that any interference the developer distract from the actual work.

So are an extraordinary nuisance emails to the developers!

In his view, this is because a programmer after distraction (eg reading an e-mail) requires 15 to 60 minutes to get back into the labor EPAM.

In addition, the error rate increases after such an interruption.

Whether this training period is really so high, in some cases even address.

But what I anzweifel that these times with position optimization can lead to a 35% performance increase.

Many of these so-called disorder namely also positive sides:

• They can teach technical information. Emails, information for the currently existing problem, to which the developer works include. However, a colleague who came past, do his opinion and his ideas for the current task known.
• Emails or conversations with colleagues can be informative for the developer generally professionally. It can provide general information about the company or the work to be conveyed, such as dates for the next meeting, the current status of the ongoing project, etc. These messages would otherwise have otherwise come to the developer, which also resumes Time Developer to complete.
• Finally, there is also the call or the e-mail of a private nature, postive sides. Not only did a little break sometimes is good, it can also happen that one a current problem after an interruption considered differently than before. Because even a distance from the current work is created by a change of subject.

Especially while working out a solution to a problem can sometimes be Decisive interruption, as I myself have noticed again and again.

After all, who does not know to have long been nibbling on an issue and then, to find suddenly after a short break the solution.

Of course, an excessive seizures of "disturbances" do not fördernt, but this leads to 35% loss of productivity?

There is also the dustbin of meaningless circulars or other spam.

What do you think, what is your opinion?

Innovative internet sites win 50,000 euros at enable2start

More than 700 company founders This year competed "enable2start" the Financial Times Germany (FTD) at founder Competition.

Now the winners have been chosen as the site Biz-Award reported.

Amazing to me that's schöne prize money of 250,000 euros, which will receive the 5 winners in total.

25,000 euros was awarded each winner immediately after the selection by the jury in October 2008, another 25,000 euros to follow six months later.

What is striking is that Internet service providers are 3 of the 5 companies.

Here the winners

statista.orgFirst place won the statistics portal statista.org.

The entrepreneur and statisticians Friedrich Schwandt and Tim Kröger bidding economic and entertaining data statistically processed to.

To objectively offer technically correct statistics, the data are processed by a team of statisticians, editors and database experts.

tortoise-design.com
The company Tortoise Design is specialized PCs and mobile phones with the most unlikely motifs such as flowers, photos or even comics to embellish.

To this end, the company has designed the adhesive films fit exactly on keyboards and other devices and also can be removed again without any problems.

wikando.comThe portal wikando.com offers companies and individuals the opportunity to find needy organizations and to support them.

In addition, fundraisers can be made so public.

freizeitpark-im-hanffeld.de
This company consisting of three farmers from Bavaria, corn and hemp fields transformed into labyrinths in order to come again to their figures, even city dwellers to enjoy a natural Parks.

However, where is to be the innovative here is beyond me, finally, there is something for a long time.

allyve.com
allyve.com is an Internet service provider who can sign up for a user up to 14 accounts with passwords and automatically logs on the sides for this.

So one need only to log on to the as all 14 pages a.

Apart from statistika and allyve I find the idea now not so very creative and original as the initiators write about their competition.

But still I think it's great that the Financial Times has conducted diesen competition.

For through such contests have many startups only the opportunity to present their company to a greater Rahmen and in addition you have to get a really good cash injection.

Change BackColor of ToolStrip and ToolStripLabel: VB.NET

Some things look so simple, if you want it then make but, then one is suddenly as the ox Vormberg.

A good example of this is changing the BackColor Property of the ToolStrip object or the ToolStrip labels, namely at runtime.

Simply by assigning a color of the BackColor property this is not done namely!

If you want to change the background color of these objects, we must first turn on the Render Mode of ToolStrip object on "System".

Although there are three different render modes for the ToolStrip, but only "System" allows changing the background color.

The Render Mode you can make on the Properties in Visual Studio or of course in code.

But beware: Visual Studio sets the RenderMode immediately on "System" when this would happen at some point in the program.

It is not to change this property at runtime in code!

So much on the subject.

I was quite surprised when the BackColor allocation not achieved the desired effect at the first time.

That is why I hope this tip can now keep one or the other of you in front of it

What to look for when SQL Server Compact Edition 3.5

The SQL Server CE is the mobile version of the SQL Server family.

So you need to install only a few DLLs and you've got a running SQL Server environment on their PC.

Also this needs no constant maintenance and not as much computing power as it has no active service.

But where are advantages, the disadvantages are not be far. Unfortunately, these are often concealed from Microsoft, Â and so the naive programmers true then completely surprised to strange limitations.

Just Wenna with your Visual Studio programming in VB.NET, C #, or the like, but these are massive striking.

A Practical Introduction is IHRA in my video tutorial: Vb.net and SQL Server Compact Edition

New objects without Provider Factory Support

As for any other provider type also, there is the Visual Studio especially for the Compact Edition own provider objects.

Advance Denkte software developers using the Provider Factory will, however, experience a nasty surprise here.

Because this support (yet) the CE objects. So here a little but must be tricked.

By the way, if you seek the Compact Edtion objects in vain, you have that extra embed "Add Reference" on.

No true 64-bit support

The server does not support 64-bit technology.

However, since all 32-bit Applikaitonen also run on 64-bit, you can work around this problem, in which one that the server uses his program explicitly as a 32-bit program is compiled (see this article )

No comprehensive data types support

If you just tried instead of SQL Server that use Compact Edition as a database, it can quickly lead to nasty surprises.

Since not stand here the same data types, it can quickly lead to errors when creating tables and columns.

Hiera You can find an overview of the data types gegenübergestelltenÂ

Lack of Object support SqlCeConnection

During testing, I came several times for errors, since some properties are not supported vonm SqlCeConnection- object may or may not be assigned.

So am also encountered the totally funny error message saying that Command timeouts NOT equal to zero may be!

But SqlCeConnection.GetSchema is not supported.

no BulkCopy - Object

For me it was very annoying that there is no object for SqlBulkCopy equivalent thereof.

This enables hineinzuladen entire tables from a foreign source to an existing database table of the SQL server.

Slower processing

Since this running locally, and has no active service, the Compact Edition compared to the larger SQL server versions is much slower.

There are probably a few more things that could be mentioned Hiera, me they are just not noticed. Do you know yet what?

Watching in SQL Server Compact Edition data types

Since I want to point you to a couple of special features relating to the data types of SQL Server CE just with the SQL Server Compact Edition work.

Because with the Compact Edition unfortunately lacks some datatypes in the express as well as the fee-based SQL Server - versions are available.

Peculiarities with regard to the Visual Studio and the Compact Edtion I'm in a different article explaining further.

A practical introduction for this you will find in my video tutorial: Vb.net and SQL Server Compact Edition

Different data types

Observance of the various data types is important both for creating tables, but also for the behavior of the server when replicating.

Besides, it can especially when moving an application from a "real" SQL Server application on a compact variant lead to increased problems (this I recommend you to read the above-mentioned article).

The following table, which also takes you on one of the MSDN Web sites of Microsoft, shows the data type mappings that are executed when replicating between SQL Server and Microsoft SQL Server Compact Edition.

It lists the assignments of the SQL Server data types and describes limitations and special behaviors.

SQL Server data type	Datatype of SQL Server Compact Edition

character varying(MAX)(Synonym:varchar(MAX))	ntext If the length of the character varying (MAX) -data the length of the ntext column exceeds that synchronization signals while sending data from SQL Server to SQL Server Compact Edition an error.
Computed Columns	is not supported. If you use and indicate that SQL Server Compact Edition subscriptions will use the Publication Wizard, each column of the data type Computed Column partitioned vertically from the publication. If you do not use the wizard, you must exclude columns of this data type in the publication.
