Shallow Copy vs DeepCopy in C#.NET

Hope below example helps to understand the difference. Please drop a comment if any doubts. using System; using System.IO; using System.Runtime.Serialization.Formatters.Binary; namespace ShallowCopyVsDeepCopy { class Program { static void Main(string[] args) { var e1 = new Emp { EmpNo = 10, EmpName = "Smith", Department = new Dep { DeptNo = 100, DeptName = "Finance" } }; var e2 = e1.ShallowClone(); e1.Department.DeptName = "Accounts"; Console.WriteLine(e2.Department.DeptName); var e3 = new Emp { EmpNo = 10, EmpName = "Smith", Department = new Dep { DeptNo = 100, DeptName = "Finance" } }; var e4 = e3.DeepClone(); e3.Department.DeptName = "Accounts"; Console.WriteLine(e4.Department.DeptName); } } [Serializable] class Dep { public int DeptNo { get; set; } public String DeptName { get; set; } } [Serializable] class Emp { public int EmpNo { get; set; } public String EmpName { get; set; } public Dep Department { get; set; } public Emp ShallowClone() { return (Emp)this.MemberwiseClone(); } public Emp DeepClone() { MemoryStream ms = new MemoryStream(); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(ms, this); ms.Seek(0, SeekOrigin.Begin); object copy = bf.Deserialize(ms); ms.Close(); return copy as Emp; } } } span.fullpost {display:none;}

Useful git commit messages for merged branches

- by eykanal

As a follow-up to this question: If I'm working on a team by myself, I can maintain useful commit messages when merging branches by squashing all the commits to a single diff and then merging that diff. That way I can easily see what changes were introduced in the branch, and I have a single summary describing the feature/change/whatever that was accomplished in that branch when browsing the master branch. My question now is, how can I accomplish this when working with a team? In that situation, the branches will be pushed to a remote repository, meaning that I can't squash all the commits in the branch down to a single commit. If the branch is public, can I still have a single useful merge commit in the master branch? (By "useful" I mean that the commit in the master line tells me (1) a useful summary of what was done in the branch and (2) diffs of the same.)

Feedback from SQLBits 8

- by Peter Larsson

This years SQLBits occurred in Brighton. Although I didn’t have the opportunity to attend the full conference, I did a presentation at Saturday. Getting to Brighton was easy. Drove to Copenhagen airport at 0415, flew 0605 and arrived at Gatwick 0735. Then I took the direct train to Brighton and showed up at 0830, just one hour before presenting. This was the easy part. Getting home was much worse. Presentation ended at 1030 and I had to rush to the train station to get back to London, change to tube for Heathrow. Made it at the gate just 15 seconds before closing. That included a half mile run in the airport… Anyway, yesterday I got the feedback for my presentation. It does look good, especially since English is not my first language. This is the first graph Seems to be just halfway between conference average and best session. I can live with that. Second graph shows more detail about attendees voting. It also look acceptable. A wider spread for the 9’s, but it is an inevitable effect from how attendees percept the session. I did get a lot of 8’s and the lower grades in an descending order. The two people voting 4 and 5 didn’t say why they voted this so I don’t know how to remedy this. Third graph is about each category of votes. Again, I find this acceptable. The Session abstract and Speaker’s knowledge seems to follow attendees expectations compared to conference average. I seem to have met the attendees expectations (and some more) for the other four categories, also compared to conference average. Since this did encourage me, I believe I will present some more at future meetings. I do have a new presentation about something all developers are doing every day but they may not know it. I will also cover this new topic in the next Deep Dives II book. Stay tuned! //Peter

How to get innovation in product development?

- by simonsabin

I was at Redgate last week and say plastered all over the canteen wall flip chart sheets with ideas scrawled over them. I was going to take a photo but thought it might not be allowed. I asked what it was all about and they told me that ALL the development team are going to stop working on what they are doing and do whatever they want. Whatever they want? yes So thats the whole team working on something? No, it can be individual or in groups. Having worked in product teams before I and the others...(read more)

Project Management Techniques (high level)

- by Sam J

Our software dev team is currently using kanban for our development lifecycles, and, from the reasonably short experience of a few months, I think it's going quite well (certainly compared to a few months ago when we didn't really have a methodology). Our team, however, is directed to do work defined by project managers (not software project managers, just general business), and they're using the PMBOK methodology. Question is, how does a traditional methodology like PMBOK, Prince2 etc fit with a lean software development methodology like kanban or scrum? Is it just wasting everyone's time as all the requirements are effectively drawn up to start with (although inevitably changed along the way)?

SQL Saturday #89 in Atlanta!

- by Most Valuable Yak (Rob Volk)

(Yeah yeah, technically it's in Alpharetta, but it's close enough.) Saturday…Saturday….Saturday…. September 17th. TWO THOUSAND ELEVEN! OK, it's not a tractor pull, but it's even better: FREE SQL SERVER TRAINING! They have a bunch of great speakers lined up, and for some reason, me. (Protip: be good friends with the program committee, have sufficient bribe funds, and if all else fails, lots of alcohol, drugs and a camera. Ba-ZING! You too can speak at SQL Saturday!) I will be presenting Revenge: The SQL! in a new and improved SQL Saturday themed presentation. Actually, it's the same ol' presentation, I just updated the slide theme to match the new SQL Saturday website design. (Yeah guys, thanks for changing that a month ago. So much for coasting on the old format.) Of course, you have your choice of three other SQL Saturdays in other cities that day, but come on, you really want to go to this one. #sqlsat89 #sqlsaturday #sqlkilt #sqlpass

VMMap - awesome memory analysis tool

VMMap is a process virtual and physical memory analysis utility. It shows a breakdown of a process's committed virtual memory types as well as the amount of physical memory (working set) assigned by the operating system to those types. Besides graphical representations of memory usage, VMMap also shows summary information and a detailed process memory map. Powerful filtering and refresh capabilities allow you to identify the sources of process memory usage and the memory cost of application features. Besides flexible views for analyzing live processes, VMMap supports the export of data in multiple forms, including a native format that preserves all the information so that you can load back in. It also includes command-line options that enable scripting scenarios. VMMap is the ideal tool for developers wanting to understand and optimize their application's memory resource usage. span.fullpost {display:none;}

ClearTrace Performance on 170GB of Trace Files

- by Bill Graziano

I’ve always worked to make ClearTrace perform well. That’s probably because I spend so much time watching it work. I’m often going through two or three gigabytes of trace files but I rarely get the chance to run it on a really large set of files. One of my clients wanted to run a full trace for a week and then analyze the results. At the end of that week we had 847 200MB trace files for a total of nearly 170GB. I regularly use 200MB trace files when I monitor production systems. I usually get around 300,000 statements in a file that size if it’s mostly stored procedures. So those 847 trace files contained roughly 250 million statements. (That’s 730 bytes per statement if you’re keeping track. Newer trace files have some compression in them but I’m not exactly sure what they’re doing.) On a system running 1,000 statements per second I get a new file every five minutes or so. It took 27 hours to process these files on an older development box. That works out to 1.77MB/second. That means ClearTrace processed about 2,654 statements per second. You can query the data while you’re loading it but I’ve found it works better to use a second instance of ClearTrace to do this. I’m not sure why yet but I think there’s still some dependency between the two processes. ClearTrace is almost always CPU bound. It’s really just a huge, ugly collection of regular expressions. It only writes a summary to its database at the end of each trace file so that usually isn’t a bottleneck. At the end of this process, the executable was using roughly 435MB of RAM. Certainly more than when it started but I think that’s acceptable. The database where all this is stored started out at 100MB. After processing 170GB of trace files the database had grown to 203MB. The space savings are due to the “datawarehouse-ish” design and only storing a summary of each trace file. You can download ClearTrace for SQL Server 2008 or test out the beta version for SQL Server 2012. Happy Tuning!

PASS: Total Registrations

- by Bill Graziano

At the Summit you’ll see PASS announce the total attendance and the “total registrations”. The total registrations is the sum of the conference attendees and the pre-conference registrations. A single person can be counted three times (conference plus two pre-cons) in the total registration count. When I was doing marketing for the Summit this drove me nuts. I couldn’t figure out why anyone would use total registrations. However, when I tried to stop reporting this number I got lots of pushback. Apparently this is how conferences compare themselves to each other. Vendors, sponsors and Microsoft all wanted to know our total registration number. I was even asked why we weren’t doing more “things” that people could register for so that our number would be even larger. This drove me nuts. I understand that many of you are very detail oriented. I just want to make sure you understand what numbers you’re seeing when we include them in the keynote at the Summit.

My History of Visual Studio (Epilog)

Visual Studio 2010 Launched on Monday. Wow! Its HUGE. A major round of congratulations are in order for everyone involved, not just on the Visual Studio team but also on the Frameworks team and the supporting teams and of course the customers whose feedback was so vital to the success of the product. Ive already written a lot about VS2010 previously in the series and I dont want to go over all that stuff again. In my last history posting, back when Beta 2 came out, I covered...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

Dealing with technical debt

- by Desolate Planet

This is a question that I often ask myself when working with developers. I've worked at four companies so far, and I've noticed a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than take something like MySQL and that created hell for the team when refacoring or extending the app. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale and in their attitude towards others. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving and the company becomes a revolving door with developers coming and and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

Tracking "To Do" Items

- by Bill Graziano

One of the challenges I struggle with is keeping a good "to do" list of things I need to do on the various SQL Servers I support. I have servers that I don't visit on a regular basis so my situation may be different than many of you. Though I'm sure you all have servers that you only touch every few months. (And it's usually the accounting server!) It's difficult for me to remember what changes I made and what changes I need to make. I've tried Outlook, OneNote and various other to do list managers and haven't been happy with any of them. Many are close but just don't give me what I need. As a result I've started writing my own. It's web-based so you can use it from anywhere -- including on a server. It also knows just enough about SQL Server to help structure your to do items and your notes. It isn't agent based and doesn't do any monitoring. Think OneNote or Evernote but with some "SQL Servery" stuff built in. If you'd like to try this or take a survey I'm putting together, add your email address to my mailing list. I should be ready in a week or so. I'm only going to use this list for notifications about this service. I'd like to find a small group of people that feel the same pain I do and maybe we can build something interesting.

Experimenting with other search engines

- by Bill Graziano

I’ve been a Google user so long I can hardly remember what I used before it. Alta Vista maybe? Or Yahoo. I’ve tried Bing off and on but it never really stuck. I probably care more about search engines than your average user because of their impact on SQLTeam.com. Lately I’ve been trying two other search engines and actually switched to one of them. I’ve played with Blekko a little in the past. They have some interesting ways to “slice up” your results. For example, searching on “SQL Server /blogs /date” should just search all the recently updated blogs. Those two extra words on the search are slashtags. The full list of slashtags runs from /forums to just see forums to /twitter to /nikon to /reviews and on and on and on. I laughed when I saw they had slashtags for both liberal and conservative. I’d hate to find any search results that don’t match my existing worldview :) You can also create your own slashtags. I created a mini-search engine for the SQL Server blogs that I read. You can search it for “backup” at http://blekko.com/ws/backup+/billgraziano/sql-sites. I uploaded my OPML and it limited the search to just those sites. It seems like the site is focusing more on curating results and less on algorithms. This is an interesting site for those power searchers. There are some great ways to curate results using slashtags. For 99% of my searches (type words, click on one of the first few links) slashtags are overkill. They do have some good information on page and site ranking though so I’ll probably send some time looking through that. Blekko recently got my attention again when they said they were banning “content farms” - and that includes eHow and experts-exchange. I always feel used when I click on a link to EE and find myself scrolling all the way to the bottom to see if I can find the answer. Sometimes it’s there but sometimes it tells me I need to pay first. I’ve longed for a way to always exclude certain sites. Blekko might be taking a hammer to a problem that needs a scalpel but it’s an interesting choice. (And some of the comments in the TechCrunch link are interesting if you’re a search nerd.) DuckDuckGo is an odd name for a search engine. Their big hook is that they don’t have search history. If you wade through your Google account you can probably find the page where it stores your search history. It was pretty enlightening to find mine. It was easy to disable but that got me started looking at other search engines. DDG (or DukGo) just feels like Google used to in the old days. The results are good enough and the site is fast. Searches will return a snippet from WikiPedia or other site (like StackOverflow) at the top. I think the idea is to answer the question without needing to visit the site. I’m not sure that’s a good thing for SQLTeam.com. The only thing I really miss is image search. You can add a “!i” at the end of any search and it will search the images on Bing. Bing doesn’t have a great image search but it works for most of what I need. They call these exclamation marks “!bangs” and they are kinda, sorta like slashtags. I’ve been using DuckDuckGo now for a few weeks and I’m pretty happy with it. I use Chrome for my browser and it was an easy switch to make. It’s still a little surprising seeing my search results come up in a different format. I’m starting to get used to it though.

Q&A: Where does high performance computing fit with Windows Azure?

Answer I have been asked a couple of times this year about taking compute intensive operations to Windows Azure and/or High Performance Computing on Windows Azure. It is an interesting (if slightly niche) area. The good news is we have a great paper from David Chappell on HPC Server and Windows Azure integration. As a taster: A SOA application running entirely on Windows Azure runs its WCF services in Azure Worker nodes.

What is a clean Agile (Scrum) Sprint Presentation?

- by negarnil

Suppose someone of your development team is presenting the a sprint to the customer but he is having web connection problems such that a complete storie cannot be presented. For the sake of the cleanness of the presentation, do you help your collegue suggesting posible solutions and try to fix it in the moment? Or is it kind of messy? May be the client (who is "part" of the team) will understand? Why? I'm really looking forward for a good answer! Regards,

PASS Summit 2011: Save Money Now

- by Bill Graziano

Register by March 31st and save $200. On April 1st we increase the price. On July 1st we increase it again. We have regular price bumps all the way through to the Summit. You can save yourself $200 if you register by Thursday. In two years of marketing for PASS and a year of finance I’ve learned a fair bit about our pricing, why we do this and how you react to it. Let me help you save some money! Price bumps drive registrations. We see big spikes in the two weeks prior to a price increase. Having a deadline with a cost attached is a great motivator to get people to take action. Registering early helps you and it helps PASS. You get the exact same Summit at a cheaper rate. PASS gets smoother cash flow and a better idea of how many people to expect. We also get people that are already registered that will tell their friends about the conference. This tiered pricing lets us serve those that are very price conscious. They can register early and take advantage of these discounts. I know there are people that pay for this conference out of their own pockets. This is a great way for those people to reduce the cost of the conference. (And remember for next year that our cheapest pricing starts right after the Summit and usually goes up around the first of the year.) We also get big price bumps after we announce the program and the pre-conference sessions. If you wrote down the 50 or so best known speakers in the SQL Server community I’m guessing we’ll have nearly all of them at the conference. We did last year. I expect we will this year too. We’re going to have good sessions. Why wait? Register today. If you want to attend a pre-conference session you can always add it to your registration later. Pre-con prices don’t change. It’s very easy to update your registration and add a pre-conference session later. I want as many people as possible to attend the Summit. It’s been a great experience for me and I hope it will be for you. And if you are going to go, do yourself a favor and save some money. Register today!

What software development model has worked best for software teams with heavy dependancy on hardware teams?

- by MasterDIB

So, let me explain more. There are a number of competing best practices for software development. I can find that many teams have benefited from Agile practices in some cases. In some other cases, using the Unified Process has been championed by large companies like IBM. The common themes that I find seemed to work well for teams that mainly develop software. I am interested to know what has worked best for people who have worked in shops where there is a team on the other side that produce the hardware that your software is running on. For example, one team puts together a crate with several custom hardware on it; while you need to develop the software that would run on those crates. I can't find a development model (agile, spiral ...) that works best in this case. Any wisdom is this area will be well appreciated.
