  • T4 Performance Counters explained

    - by user13346607
    Now that T4 is out for a few month some people might have wondered what details of the new pipeline you can monitor. A "cpustat -h" lists a lot of events that can be monitored, and only very few are self-explanatory. I will try to give some insight on all of them, some of these "PIC events" require an in-depth knowledge of T4 pipeline. Over time I will try to explain these, for the time being these events should simply be ignored. (Side note: some counters changed from tape-out 1.1 (*only* used in the T4 beta program) to tape-out 1.2 (used in the systems shipping today) The table only lists the tape-out 1.2 counters) 0 0 1 1058 6033 Oracle Microelectronics 50 14 7077 14.0 Normal 0 false false false EN-US JA X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:Cambria; mso-ascii-font-family:Cambria; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Cambria; mso-hansi-theme-font:minor-latin;} pic name (cpustat) Prose Comment Sel-pipe-drain-cycles, Sel-0-[wait|ready], Sel-[1,2] Sel-0-wait counts cycles a strand waits to be selected.

  • Developing a Cost Model for Cloud Applications

    - by BuckWoody
    Note - please pay attention to the date of this post. As much as I attempt to make the information below accurate, the nature of distributed computing means that components, units and pricing will change over time. The definitive costs for Microsoft Windows Azure and SQL Azure are located here, and are more accurate than anything you will see in this post: http://www.microsoft.com/windowsazure/offers/  When writing software that is run on a Platform-as-a-Service (PaaS) offering like Windows Azure / SQL Azure, one of the questions you must answer is how much the system will cost. I will not discuss the comparisons between on-premise costs (which are nigh impossible to calculate accurately) versus cloud costs, but instead focus on creating a general model for estimating costs for a given application. You should be aware that there are (at this writing) two billing mechanisms for Windows and SQL Azure: “Pay-as-you-go” or consumption, and “Subscription” or commitment. Conceptually, you can consider the former a pay-as-you-go cell phone plan, where you pay by the unit used (at a slightly higher rate) and the latter as a standard cell phone plan where you commit to a contract and thus pay lower rates. In this post I’ll stick with the pay-as-you-go mechanism for simplicity, which should be the maximum cost you would pay. From there you may be able to get a lower cost if you use the other mechanism. In any case, the model you create should hold. Developing a good cost model is essential. As a developer or architect, you’ll most certainly be asked how much something will cost, and you need to have a reliable way to estimate that. Businesses and Organizations have been used to paying for servers, software licenses, and other infrastructure as an up-front cost, and power, people to the systems and so on as an ongoing (and sometimes not factored) cost. When presented with a new paradigm like distributed computing, they may not understand the true cost/value proposition, and that’s where the architect and developer can guide the conversation to make a choice based on features of the application versus the true costs. The two big buckets of use-types for these applications are customer-based and steady-state. In the customer-based use type, each successful use of the program results in a sale or income for your organization. Perhaps you’ve written an application that provides the spot-price of foo, and your customer pays for the use of that application. In that case, once you’ve estimated your cost for a successful traversal of the application, you can build that into the price you charge the user. It’s a standard restaurant model, where the price of the meal is determined by the cost of making it, plus any profit you can make. In the second use-type, the application will be used by a more-or-less constant number of processes or users and no direct revenue is attached to the system. A typical example is a customer-tracking system used by the employees within your company. In this case, the cost model is often created “in reverse” - meaning that you pilot the application, monitor the use (and costs) and that cost is held steady. This is where the comparison with an on-premise system becomes necessary, even though it is more difficult to estimate those on-premise true costs. For instance, do you know exactly how much cost the air conditioning is because you have a team of system administrators? This may sound trivial, but that, along with the insurance for the building, the wiring, and every other part of the system is in fact a cost to the business. There are three primary methods that I’ve been successful with in estimating the cost. None are perfect, all are demand-driven. The general process is to lay out a matrix of: components units cost per unit and then multiply that times the usage of the system, based on which components you use in the program. That sounds a bit simplistic, but using those metrics in a calculation becomes more detailed. In all of the methods that follow, you need to know your application. The components for a PaaS include computing instances, storage, transactions, bandwidth and in the case of SQL Azure, database size. In most cases, architects start with the first model and progress through the other methods to gain accuracy. Simple Estimation The simplest way to calculate costs is to architect the application (even UML or on-paper, no coding involved) and then estimate which of the components you’ll use, and how much of each will be used. Microsoft provides two tools to do this - one is a simple slider-application located here: http://www.microsoft.com/windowsazure/pricing-calculator/  The other is a tool you download to create an “Return on Investment” (ROI) spreadsheet, which has the advantage of leading you through various questions to estimate what you plan to use, located here: https://roianalyst.alinean.com/msft/AutoLogin.do?d=176318219048082115  You can also just create a spreadsheet yourself with a structure like this: Program Element Azure Component Unit of Measure Cost Per Unit Estimated Use of Component Total Cost Per Component Cumulative Cost               Of course, the consideration with this model is that it is difficult to predict a system that is not running or hasn’t even been developed. Which brings us to the next model type. Measure and Project A more accurate model is to actually write the code for the application, using the Software Development Kit (SDK) which can run entirely disconnected from Azure. The code should be instrumented to estimate the use of the application components, logging to a local file on the development system. A series of unit and integration tests should be run, which will create load on the test system. You can use standard development concepts to track this usage, and even use Windows Performance Monitor counters. The best place to start with this method is to use the Windows Azure Diagnostics subsystem in your code, which you can read more about here: http://blogs.msdn.com/b/sumitm/archive/2009/11/18/introducing-windows-azure-diagnostics.aspx This set of API’s greatly simplifies tracking the application, and in fact you can use this information for more than just a cost model. After you have the tracking logs, you can plug the numbers into ay of the tools above, which should give a representative cost or in some cases a unit cost. The consideration with this model is that the SDK fabric is not a one-to-one comparison with performance on the actual Windows Azure fabric. Those differences are usually smaller, but they do need to be considered. Also, you may not be able to accurately predict the load on the system, which might lead to an architectural change, which changes the model. This leads us to the next, most accurate method for a cost model. Sample and Estimate Using standard statistical and other predictive math, once the application is deployed you will get a bill each month from Microsoft for your Azure usage. The bill is quite detailed, and you can export the data from it to do analysis, and using methods like regression and so on project out into the future what the costs will be. I normally advise that the architect also extrapolate a unit cost from those metrics as well. This is the information that should be reported back to the executives that pay the bills: the past cost, future projected costs, and unit cost “per click” or “per transaction”, as your case warrants. The challenge here is in the model itself - statistical methods are not foolproof, and the larger the sample (in this case I recommend the entire population, not a smaller sample) is key.

  • Azure Diagnostics: The Bad, The Ugly, and a Better Way

    - by jasont
    If you’re a .Net web developer today, no doubt you’ve enjoyed watching Windows Azure grow up over the past couple of years. The platform has scaled, stabilized (mostly), and added on a slew of great (and sometimes overdue) features. What was once just an endpoint to host a solution, developers today have tremendous flexibility and options in the platform. Organizations are building new solutions and offerings on the platform, and others have, or are in the process of, migrating existing applications out of their own data centers into the Azure cloud. Whether new application development or migrating legacy, every development shop and IT organization needs to monitor their applications in the cloud, the same as they do on premises. Azure Diagnostics has some capabilities, but what I constantly hear from users is that it’s either (a) not enough, or (b) too cumbersome to set up. Today, Stackify is happy to announce that we fully support Azure deployments, just the same as your on-premises deployments. Let’s take a look below and compare and contrast the options. Azure Diagnostics Let’s crack open the Windows Azure documentation on Azure Diagnostics and see just how easy it is to use. The high level steps are:   Step 1: Import the Diagnostics Oh, I’ve already deployed my app without the diagnostics module. Guess I can’t do anything until I do this and re-deploy. Step 2: Configure the Diagnostics (and multiple sub-steps) Do I want it all? Or just pieces of it? Whoops, forgot to include a specific performance counter, I guess I’ll have to deploy again. Wait a minute… I have to specifically code these performance counters into my role’s OnStart() method, compile and deploy again? And query and consume it myself? Step 3: (Optional) Permanently store diagnostic data Lucky for me, Azure storage has gotten pretty cheap. But how often should I move the data into storage? I want to see real-time data, so I guess that’s out now as well. Step 4: (Optional) View stored diagnostic data Optional? Of course I want to see it. Conveniently, Microsoft recommends 3 tools to do this with. Un-conveniently, none of these are web based and they all just give you access to raw data, and very little charting or real-time intelligence. Just….. data. Nevermind that one product seems to have gotten stale since a recent acquisition, and doesn’t even have screenshots!   So, let’s summarize: lots of diagnostics data is available, but think realistically. Think Dev Ops. What happens when you are in the middle of a major production performance issue and you don’t have the diagnostics you need? You are redeploying an application (and thankfully you have a great branching strategy, so you feel perfectly safe just willy-nilly launching code into prod, don’t you?) to get data, then shipping it to storage, and then digging through that data to find a needle in a haystack. Would you like to be able to troubleshoot a performance issue in the middle of the night, or on a weekend, from your iPad or home computer’s web browser? Forget it: the best you get is this spark line in the Azure portal. If it’s real pointy, you probably have an issue; but since there is no alert based on a threshold your customers have likely already let you know. And high CPU, Memory, I/O, or Network doesn’t tell you anything about where the problem is. The Better Way – Stackify Stackify supports application and server monitoring in real time, all through a great web interface. All of the things that Azure Diagnostics provides, Stackify provides for your on-premises deployments, and you don’t need to know ahead of time that you’ll need it. It’s always there, it’s always on. Azure deployments are essentially no different than on-premises. It’s a Windows Server (or Linux) in the cloud. It’s behind a different firewall than your corporate servers. That’s it. Stackify can provide the same powerful tools to your Azure deployments in two simple steps. Step 1 Add a startup task to your web or worker role and deploy. If you can’t deploy and need it right now, no worries! Remote Desktop to the Azure instance and you can execute a Powershell script to download / install Stackify.   Step 2 Log in to your account at www.stackify.com and begin monitoring as much as you want, as often as you want and see the results instantly. WMI? It’s there Event Viewer? You’ve got it. File System Access? Yes, please! Would love to make sure my web.config is correct.   IIS / App Pool Info? Yep. You can even restart it. Running Services? All of them. Start and Stop them to your heart’s content. SQL Database access? You bet’cha. Alerts and Notification? Of course! You should know before your customers let you know. … and so much more.   Conclusion Microsoft has shown, consistently, that they love developers, developers, developers. What every developer needs to realize from this is that they’ve given you a canvas, which is exactly what Azure is. It’s great infrastructure that is readily available, easy to manage, and fairly cost effective. However, the tooling is your responsibility. What you get, at best, is bare bones. App and server diagnostics should be available when you need them. While we, as developers, try to plan for and think of everything ahead of time, there will come times where we need to get data that just isn’t available. And having to go through a lot of cumbersome steps to get that data, and then have to find a friendlier way to consume it…. well, that just doesn’t make a lot of sense to me. I’d rather spend my time writing and developing features and completing bug fixes for my applications, than to be writing code to monitor and diagnose.

  • SQL Sentry First Impressions

    - by AjarnMark
    After struggling to defend my SQL Servers from a political attack recently, I realized that I needed better tools to back me up, and SQL Sentry is the leading candidate. A couple of weeks ago, seemingly from out of nowhere, complaints from the business users started coming in that one of the core internal applications was running dramatically slower than normal, and fingers were being pointed at the SQL Server.  Unfortunately, we don’t have a production DBA whose entire job is to monitor and maintain our SQL Servers.  The responsibility falls to me to do the best I can, investing only a small portion of my time, because there are so many other responsibilities to take care of, and our industry is still deep in recession.  I inherited these SQL Servers and have made significant improvements in process and procedure, but I had not yet made the time to take real baseline measurements or keep a really close eye on the performance.  Like many DBAs, I wrote several of my own tools and used the “built-in tools” like Profiler, PerfMon, and sp_who2 (did I mention most of our instances are SQL Server 2000?).  These have all served me well for in-the-moment troubleshooting and maintenance, but they really fell down on the job when I was called upon to “prove” that SQL Server performance was acceptable and more importantly had not degraded recently (i.e. historical comparisons).  I really didn’t have anything from a historical comparison perspective, but I was able to show that current performance was acceptable, and deflect attention back onto other components (which in fact turned out to be the real culprit). That experience dramatically illustrated the need for better monitoring tools.  Coincidentally, I had been talking recently to my boss about the mini nightmare of monitoring several critical and interdependent overnight jobs that operate on separate instances of SQL Server.  Among other tools, I had been using Idera’s SQL Job Manager which is a free tool and did a nice job of showing me job schedules and histories in a nice calendar view.  This worked fairly well, and for the money (did I mention it was free?) it couldn’t be beat.  But it is based on the stored job history in MSDB, and there were other performance problems that we ran into when we started changing the settings for how much job history to retain, in order to be able to look back a month or more in the calendar view.  Another coincidence (if you believe in such things) was that when we had some of those performance challenges, I posted a couple of questions to the #sqlhelp hashtag on Twitter and Greg Gonzalez (@SQLSensei) suggested I check out SQL Sentry’s Event Manager.  At the time, I just thought he worked there, but later found out that he founded the company.  When I took a quick look at the features & benefits, the one that really jumped out at me is Chaining and Queueing which sounded like it would really help with our “interdependent jobs on different servers” issue. I know that is a lot of background story and coincidences, but hopefully you have stuck with me so far, and now we have arrived at the point where last week I downloaded and installed the 30-day trial of the SQL Sentry Power Suite, which is Event Manager plus Performance Advisor.  And I must say that I really like what I see so far.  Here are a few highlights: Great Support.  I had two issues getting the trial setup and monitoring a handful of our servers.  One of which was entirely my fault (missed a security setting in SQL 2008) and the other was mostly my fault (late change to some config settings that were apparently cached and did not get refreshed properly).  In both cases, the support staff at SQL Sentry were very responsive and rather quickly figured out what the cause and fix was for each of them.  This left me with a great impression of the company.  Kudos to them! Chaining and Queueing.  While I have not yet activated this feature, I am very excited about the possibilities.  We have jobs on three different instances of SQL Server that have to be run in a certain order, and each has to finish before the next can successfully begin, and I believe this feature will ensure just that.  It has been a real pain in the backside when one of those jobs runs just a little too long and does not finish before the job on another instance starts, thus triggering a chain reaction of either outright job failures, or worse, successful completion of completely invalid processing. Calendar View.  I really, really like the Event Manager calendar view where I can see all jobs and events across all instances and identify potential resource contention as well as windows of opportunity for maintenance activity.  Very well done, and based on Event Manager’s own database of accumulated historical information rather than querying the source instances every time. Performance Advisor Dashboard History View.  This view let’s me quickly select a date and time range and it displays graphs of key SQL Server and Windows metrics.  This is exactly the thing I needed to answer the “has performance changed recently” question at the beginning of this post. Reporting Services Subscription Jobs with Report Name.  This was a big and VERY pleasant surprise.  If you have ever looked at the list of SQL Server jobs that SQL Server Reporting Services creates when you make a Subscription, you will notice that they all have some sort of GUID as the name of the job.  This is really ugly, and really annoying because when you are just looking at the SQL Agent and Job Activity Monitor, if you see that Job X failed, you really do not have any indication in the name or the properties of the Job itself, as to what Report that was for.  But with SQL Sentry Event Manager you do.  The Jobs list in the Navigator pane in SQL Sentry, amazingly, displays the name of the Report that the Subscription Job is for.  And when you open it to see more details, it shows you the full Reporting Services path to that Report, so you can immediately track it down in the Report Manager in case you want to identify/notify the owner or edit the Subscription information.  I did not expect this at all, but I sure do like it.  HOORAY! That is just my first impressions from using the tools for a few days.  And I haven’t even gotten into how it showed me where I was completely mistaken about one aspect of my SQL Server disk configurations.  I’ll share that lesson in another blog entry.  But I have to say it again, the combination of Event Manager and Performance Advisor working together have really made me a fan.

  • Lenovo V570 CPU fan running constantly, CPU core 1 running over 90%!

    - by Rabbit2190
    I have seen that a lot of people are having this same issue. I am running a Lenovo V570 i5 4 core, 6 gigs of ram, and am running 11.10 Onieric Ocelot. On my system monitor graph it shows CPU at 20%, when I open the monitor it shows core #1 at around 90%, the other cores fluctuate at or below 5-12% if even. Now this seems like a really terrible balance of power between the cores, especially with so much stress on one core only, when these things are designed to work with 4 cores and not at such high temps. My current readings say 64 degrees Celsius, this does not seem normal for any cpu, and I am seriously considering, working on my windows7 partition until I see a real solution to this issue or upgrading to 12.04 right away when it comes out... I have seen countless things saying it has something to do with the Kernel, the kernel on mine is the same as when I upgraded, I really do not like messing with it, as when I had 11.04, I did tinker with it due to the freeze issues I was having, and that just made worse issues. I like this version 11.10 and would like to keep it for a while, but without the fear that my core is going to fry! So any help would be much appreciated! I did try changing a couple things in ACPI, and restarting this did not help, and here I am. I tried one thing prior to that that was listed under a different computer brand, but it would not do a make on the file. I really need help with this, I rely on this computer for a lot of things, and love this OS! Please help so I do not need to resort to my Microsoft partition! PLEASE!

  • Are you reporting Visual Studio 2012 issues to Microsoft correctly?

    - by Tarun Arora
    Issues you may run into while using Visual Studio need to be reported to the Microsoft Product Team via the Microsoft connect site. The Microsoft team then tries to reproduce the issue using the details provided by you. If the information you provide isn’t sufficient to reproduce the issue the team tries to contact you for specifics, this not only increases the cycle time to resolution but the lack of communication also results in issues not being resolved. So, when I report an issue one part of me tells me to include as much detail about the issue as I can clubbing screen shots, repo steps, system information, visual studio version information,… the other half tells me this is so time consuming, leave it for now and come back to fill all these details later. Reporting a bug but not including the supporting information is an invitation to excuses like …     Microsoft has absolutely changed this experience for VS 2012. The Microsoft Visual Studio Feedback tool is designed to simplify the process of providing feedback and reporting issues to Microsoft that you may encounter while using Microsoft Visual Studio 2012. Note – The Microsoft Visual Studio 2012 Feedback client currently only works for VS 2012 and not any other versions of Visual Studio. Setting up the Microsoft Visual Studio 2012 Feedback client Open Visual Studio, from the Tools menu select Extension and Updates. In the Extension and Updates window, click Online from the left pane and search using the text ‘feedback’, download and Install Microsoft Visual Studio 2012 Feedback Tool by following the instructions from the wizard. Note - Restarting Visual Studio after the install is a must! How to report a bug for Visual Studio 2012? Click on the Help menu and choose Report a Bug You should see an icon Microsoft Visual Studio 2012 Feedback Tool come up in the system tray icon area You’ll need to accept the Privacy statement. You have the option of reporting the feedback as private or public. Microsoft works with several Partners, MVP’s and Vendors who get access to early bits of Microsoft products for valuation. This is where it becomes essential to report the feedback privately. I would choose the Public option otherwise. After all if it’s out there in the public, others can discover and add to it easily. You now have the option to report a new issue or add to an existing issue. Should you choose to add to an existing issue you should have the feedback ID of the issue available. This can be obtained from the Microsoft Connect site. For now I am going to focus on reporting a new feedback privately. Filling out the feedback details You will notice that VsInfo.xml and DxDiagOutput.txt are automatically attached as you enter this screen (more on that later).  Feedback Type Choose the feedback type from (Performance, Hang, Crash, Other) Note – The record button will only be enabled once you have enabled once you have chosen the feedback type, Bug-repro recording is not available for Windows Server 2008.     Effective Title and Description Enter a title that helps us differentiate the bug when it appears in a list, so that we can group it with any related bugs, assign it to a developer more effectively, and resolve it more quickly. Example: Imagine that you are submitting a bug because you tried to install Service Pack 1 and got a message that Visual Studio is not installed even though it is. Helpful:  Installed Visual Studio version not detected during Service Pack 1 setup. Not helpful:  Service Pack 1 problem. Tip: Write the problem description first, and then distil it to create a title. Example Description: Helpful: When I run Service Pack 1 Setup, I get the message "No Visual Studio version is detected" even though I have Visual Studio 2010 Ultimate and Visual C++ 2010 Express installed on my machine. Even though I uninstalled both editions, and then first reinstalled Ultimate and then Express, I still get the message. Record: Becoming a first class citizen Often a repro report is invaluable to describe and decipher the issue. Please use this feature to send actionable feedback. The record repro feature works differently depending on the feedback type you selected. Please find below details for each recording option. You can start recording simply by selecting a feedback type, and clicking on the “Record” button. When "Performance" is the bug type: When the Microsoft Visual Studio trace recorder starts, perform the actions that show the performance problem you want to report and then click on the "Stop Recording" button as soon as you experience the performance problem. Because the tool optimizes trace collection, you can run it for as long as it takes to show the problem, up to two hours. Note that, you need to stop recording as soon as the performance issue occurs, because the tool captures only the last couple minutes of your actions to optimize the trace collection. After you stop the recording, the tool takes up to two minutes to assemble the data and attach an ETLTrace.zip file to your bug report. The data includes information about Windows events and the Visual Studio code path. Note that, running the Microsoft Visual Studio trace recorder requires elevated user privilege. When "Crash" is the bug type: When the dialog box appears, select the running Visual Studio instance for which you want to show the steps that cause a crash. When the crash occurs, click on the "Stop Record" button. After you do this, two files are attached to your bug report - an AutomaticCrashDump.zip file that contains information about the crash and a ReproSteps.zip file that shows the repro steps. Repro steps are captured by Windows Problem Steps Recorder. Note that, you can pause the recording, and resume later, or for a specific step, you can add additional comments. When "Hang" is the bug type: The process for recording the steps that cause a hang resembles the one for crashes. The difference is, you can even collect a dump file after the VS hangs; start the VSFT either from the system tray or by starting a new instance of VS, select "Hang" as feedback type and click on the "Record" button. You will be prompted which VS to collect dump about, select the VS instance that hanged. VSFT collects a dump file regarding the hang, called MiniDump.zip, and attaches to your bug report. When "Other" is the bug type: When the problem step recorder starts, perform the actions that show the issue you want to report and then choose the "Stop” button. You can pause the recording, and resume later, or for a specific step, you can add additional comments. Once you’re done, ReproSteps.zip is added to your bug report. Pre-attached files It is essential for Microsoft to know what version of the the product are you currently using and what is the current configuration of your system. Note – The total size of all attachments in a bug report cannot exceed 2 GB, and every uncompressed attachment must be smaller than 512 MB. We recommend that you assemble all of your attachments, compress them together into a .zip file, and then attach the .zip file. Taking a screenshot Associate a screen shot by clicking the Take screenshot button, choose either the entire desktop, the specific monitor (useful if you are working in a multi monitor configuration) or the specific window in question. And finally … click Submit If you need further help, more details can be found here. You can view your feedback online by using the following URL “">https://connect.microsoft.com/VisualStudio/SearchResults.aspx?SearchQuery=<feedbackId>” Happy bug logging

Well, only time will tell if I’m successful or a complete failure. Good thing about failures though, you know what NOT to do next time! Anyway, I’ve been writing some sort of code since I was about 10 years old; so I sometimes take for granted the effort some people have to go through to learn a new technology. I guess if I had to say I was an “expert” in one thing it would be learning (and getting “stuff” done) in new technologies. Maybe that’s why I’ve embraced SharePoint and the SharePoint community. SharePoint is the first technology I haven’t been able to master or get everything done without help from other people. I KNOW I’ll never know it all and I learn something new every day.  It keeps it interesting, it keeps me motivated, and keeps me involved. So, what some people may consider a downside of SharePoint, I definitely consider a plus. Crap.. I’m rambling. Where was I? Oh yeah… me trying to be helpful. Like I said, I am able to quickly and effectively pick up new languages, technology, etc. and put it to good use. Am I just brilliant? Well, my mom thinks so.. but maybe not. Maybe I’ve just been doing it for a long time…. 25 years in some form or fashion… wow I’m old… Anyway, what I lack in depth I make up for in breadth and being the “go-to” guy wherever I work when someone needs to “get stuff done”.  Let’s see if I can take some of that experience and put it to practical use to help new people get up to speed faster, learn things more effectively, and become that go-to guy. First off…  make sure you… Know The Basics I don’t have the time to teach new developers the basics, but you gotta know them. I’ve only been “taught” two languages.. Fortran 77 and C… everything else I’ve picked up from “doing”. I HAD to know the basics though, and all new developers need to understand the very basics of development.  97.23% of all languages will have the following: Variables Functions Arrays If statements For loops / While loops If you think about it, most development is “if this, do this… or while this, do this…”.  “This” may be some unique method to your language or something you develop, but the basics are the basics. YES there are MANY other development topics you need to understand, but you shouldn’t be scratching your head trying to figure out what a ”for loop” is… (Also learn about classes and hashtables as quickly as possible). Once you have the basics down it makes it much easier to… Learn By Doing This may just apply to me and my warped brain.  I don’t learn a new technology by reading or hearing someone speak about it. I learn by doing. It does me no good to try and learn all of the intricacies of a new language or technology inside-and-out before getting my hands dirty. Just show me how to do one thing… let me get that working… then show me how to do the next thing.. let me get that working… Now, let’s see what I can figure out on my own. Okay.. now it starts to make sense. I see how the language works, I can step through the code, and before you know it.. I’m productive in a new technology. Be careful here though…. make sure you… Don’t Reinvent The Wheel People have been writing code for what… 50+ years now? So, why are you trying to tackle ANYTHING without first Googling it with Bing to see what others have done first? When I was first learning C# (I had come from a Java background) I had to call a web service.  Sure! No problem! I’d done this many times in Java. So, I proceeded to write an HTTP Handler, called the Web Service and it worked like a charm!!!  Probably about 2.3 seconds after I got it working completely someone says to me “Why didn’t you just add a Web Reference?” Really? You can do that?  oops… I just wasted a lot of time. Before undertaking the development of any sort of utility method in a new language, make sure it’s not already handled for you… Okay… you are starting to write some code and are curious about the possibilities? Well… don’t just sit there… Try It And See What Happens This is actually one of my biggest pet peeves. “So… ‘x++’ works in C#, but does it also work in JavaScript?”   Really? Did you just ask me that? In the time it spent for you to type that email, press the send button, me receive the email, get around to reading it, and replying with “yes” you could have tested it 47 times and know the answer! Just TRY it! See what happens! You aren’t doing brain surgery. You aren’t going to kill anyone, and you BETTER not be developing in production. So, you are not going to crash any production systems!! Seriously! Get off your butt and just try it yourself. The extra added benefit is that it doesn’t work, the absolute best way to learn is to… Learn From Your Failures I don’t know about you… but if I screw up and something doesn’t work, I learn A LOT more debugging my problem than if everything magically worked. It’s okay that you aren’t perfect! Not everyone can be me? In the same vein… don’t ask someone else to debug your problem until you have made a valiant attempt to do so yourself. There’s nothing quite like stepping through code line by line to see what it’s REALLY doing… and you’ll never feel more stupid sometimes than when you realize WHY it’s not working.. but you realize... you learn... and you remember. There is nothing wrong with failure as long as you learn from it. As you start writing more and more and more code make sure that you ALWAYS… Develop for Production You will soon learn that the “prototype” you wrote last week to show as a “proof of concept” is going to go directly into production no matter how much you beg and plead and try to explain it’s not ready to go into production… it’s going to go straight there.. and it’s like herpes.. it doesn’t go away and there’s no fixing it once it’s in there.  So, why not write ALL your code like it will be put in production? It MIGHT take a little longer, but in the long run it will be easier to maintain, get help on, and you won’t be embarrassed that it’s sitting on a production server for everyone to use and see. So, now that you are getting comfortable and writing code for production it is important to to remember the… KISS Principle… Learn It… Love It… Keep It Simple Stupid Seriously.. don’t try to show how smart you are by writing the most complicated code in history. Break your problem up into discrete steps and write each step. If it turns out you have some redundancy, you can always go back and tweak your code later.  How bad is it when you write code that LOOKS cocky? I’ve seen it before… some of the most abstract and complicated classes when a class wasn’t even needed! Or the most elaborate unreadable code jammed into one really long line when it could have been written in three lines, performed just as well, and been SOOO much easier to maintain. Keep it clear and simple.. baby steps people. This will help you learn the technology, debug problems, AND it will help others help you find your problems if they don’t have to decipher the Dead Sea Scrolls just to figure out what you are trying to do…. Really.. don’t be that guy… try to curb your ego and… Keep an Open Mind No matter how smart you are… how fast you type… or how much you get paid, don’t let your ego get in the way. There is probably a better way to do everything you’ve ever done. Don’t become so cocky that you can’t think someone knows more than you. There’s a lot of brilliant, helpful people out there willing to show you tricks if you just give them a chance. A very super-awesome developer once told me “So what if you’ve been writing code for 10 years or more! Does your code look basically the same? Are you not growing as a developer?” Those 10 years become pretty meaningless if you just “know” that you are right and have not picked up new tips, tricks, methods, and patterns along the way. Learn from others and find out what’s new in development land (you know you don’t have to specifically use pointers anymore??). Along those same lines… If it’s not working, first assume you are doing something wrong. You have no idea how much it annoys people who are trying to help you when you first assume that the help they are trying to give you is wrong. Just MAYBE… you… the person learning is making some small mistake? Maybe you didn’t describe your problem correctly? Maybe you are using the wrong terminology? “I did exactly what you said and it didn’t work.”  Oh really? Are you SURE about that? “Your solution doesn’t work.”  Well… I’m pretty sure it works, I’ve used it 200 times… What are you doing differently? First try some humility and appreciation.. it will go much further, especially when it turns out YOU are the one that is wrong. When all else fails…. Try Professional Training Some people just don’t have the mindset to go and figure stuff out. It’s a gift and not everyone has it. If everyone could do it I wouldn’t have a job and there wouldn’t be professional training available.  So, if you’ve tried everything else and no light bulbs are coming on, contact the experts who specialize in training. Be careful though, there is bad training out there. Want to know the names of some good places? Just shoot me a message and I’ll let you know. I’m boycotting endorsing Andrew Connell anymore until I get that free course dangit!! So… that’s it.. that’s all I got right now. Maybe you thought all of this is common sense, maybe you think I’m smoking crack. If so, don’t just sit there, there’s a comments section for a reason. Finally, what about you? What tips do you have to help this aspiring to learn the dark arts??

  • Running mysql 5.5 on centos 5.9

    - by gerrytan
    I installed mysql using yum install mysql-server on centos 5.9 and realized it's version 5.0. I need version 5.5 so then I did yum install mysql55-server however I couldn't find a way to start server version 5.5 instead of 5.0. service mysqld start will start 5.0 server and removing mysql 5.0 doesn't help either because service mysqld start fail to find mysqld service Update 1 Nov 2013: I noticed mysql55 package was being installed to /opt/rh/mysql55/root/usr/bin, so I appended that into the start of my PATH env var but service mysqld start still runs 5.0 server. If I tried running the server using mysqld_safe located on above mysql55 path but it says [root@***** bin]# mysqld_safe Use "scl enable mysql55 'service ...'" invocation Not quite sure what it means. I checked the running mysql version by connecting to it using mysql command line client. [root@***** bin]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.0.95 Source distribution

  • HTTP response time profiling

    - by Sparsh Gupta
    Hello I have a nginx reverse proxy. The server is close to serving 600-700 requests per second. I have a Munin HTTP load time plugin which is outputting this: http://monitor.wingify.com/munin/visualwebsiteoptimizer.com/lb1.visualwebsiteoptimizer.com-http_loadtime.html Now, the problem is I am seeing some spikes in the graph. Expected response times should always be under 200ms. I am keeping an eye on syslog and messages but I am unable to figure out the actual cause of this. I was wondering if there is any good HTTP response time profiling system which I can install / embed with this nginx server and get a detailed reports / logs on the breakup of time taken by different things and what exactly is the cause of the spikes. The profiling system would also help me understand bottlenecks and how can I further optimize the latency. Most important right now is to investigate the cause of the spikes in the HTTP load time graphs (similar pattern is reported by external monitors - Pingdom) and to fix it to get consistent response times Thanks

  • Add an objective @property attribute in objective-c

    - by morticae
    Does anyone know of a way to add additional attribute types to the @property keyword without modifying the compiler? Or can anyone think of another way to genericize getter/setter creation? Basically, I have a lot of cases in a recent project where it's handy for objects to lazily instantiate their array properties. This is because we have "event" objects that can have a wide variety of collections as properties. Subclassing for particular events is undesirable because many properties are shared, and it would become a usability nightmare. For example, if I had an object with an array of songs, I'd write a getter like the following: - (NSMutableArray *)songs { if (!songs) { songs = [[NSMutableArray alloc] init]; } return songs; } Rather than writing dozens of these getters, it would be really nice to get the behavior via... @property (nonatomic, retain, lazyGetter) NSMutableArray *songs; Maybe some fancy tricks via #defines or something? Other ideas?

  • Uninitialized constant Encoding with sqlite3-ruby on windows

    - by Ben Scheirman
    On a new machine, installed ruby with the 1-click installer for windows. Installed rails 2.3.2 and all associated gems, then I installed the sqlite3 binaries (into the c:\ruby\bin folder). Lastly I did gem install sqlite3-ruby -v=1.2.3 (which is apparently the latest version that works with windows) This error happens when I run rake db:migrate or when any ActiveRecord object is touched at runtime. The error looks like this: ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate rake aborted! **uninitialized constant Encoding** <---- Any help resolving this error would be greatly appreciated!

  • Linux Server Performance Monitoring

    - by Jon
    I'm looking to monitor performance on my Linux servers (which happen to be Centos). What are the best tools for monitoring things in realtime such as: Disk Performance I/O, swapping etc.. CPU Performance Looking for low level tools, rather than web based tools such as Nagios, Ganglia etc... n.b. I'd like to know exactly what each tool does rather than just having a list of random toolnames if possible please. Why the tool is a better option than others would be good also.

  • which performance counters mainly matter for windows server performance?

    - by Karl Cassar
    We have a website which is sometimes performing slowly, and / or completely hangs. I have setted up temporarily the default system performance data collector in Performance Monitor, to see if this can shed some light. However, the default Data Collector set collects a huge amount of counters, as well as generates huge logs files. Just 8 hours of data resulted in 4GB of data. Which performance counters matter the most, when judging server load? Also, is it a performance concern if one leaves such data-collectors running indefinitely? Obviously, I will not know when the server will experience slow performance, so I need the logs there so that I can check them out. Any other specific guidelines on monitoring server performance would be greatly appreciated. OS is a Windows Server 2008 R2 (Web Edition).

  • Visual Studio 2010 Beta start without debugging Console wont stay open

    - by CousinVinny
    I want to keep the console (output) window open to view the output of the project I am working on. I have enabled the start without debugging option and added the button to the debugging toolbar, but alas it fails to keep it open nicely like in visual studio 2008. I have to add cin.getline() etc etc etc to get it to stay open, but I don't want to type it. Any suggestions as to alter it Visual Studio 2010 to keep it open, or any debugging tricks to make it easier to view output for longer than a flash. Visual Studio used to have a "Press any key to continue prompt" I want it back...

  • Usability Problems with RDP and Dual Monitors

    - by Stung
    Hi All, When I RDP into a win2k3 machine with the dual mon settings, I've noticed that there are a couple of usability problems: 1) Dialog boxes are popped up right in the middle of both monitors making it hard to read. 2) Windows are maximized to both monitors instead of just one. 3) The task bar spans across two monitors. (This is just a matter of preference. I prefer my task bar to span across just my primary monitor) I know that Splitview is a good tool that solves all these problems, but there's a price-tag to it. To be fair, $39 for a tool like this is not too bad at all. However, before I suggest this tool to my team and manager to get the licenses for it, are there any free alternatives that will solve the 3 above problems? -Steve

  • Mac does not recognize wide screen

    - by DUKE
    I am using Mac OS X Lion 10.7.4 on my Mac mini, with Samsung monitor with default resolution 1360 x 768. My Mac mini is connected to Samsung VGA port by Apple mini port to VGA adapter. When starting, my Mac does not recognize the wide screen resolution and always starts in a 4:3 mode, (but it shows 1360x768 as the resolution in the settings). I have to do one of the following actions to bring my Mac to the wide screen resolution: (1) Changing to some other resolution and bring back to the default resolution. (2) Unplug the Apple mini port to VGA adapter and re-connect again. (3) Put the machine to sleep and wake it up again. I am using Ubuntu 12.04, (in a different partition) in the same hardware, but Ubuntu is perfectly recognizing the display.

  • Apache Unclean shutdown of previous apache run

    - by Darth
    I'm having problem with running Apache2.2 on my Vista machine. When I clean install Apache it works just fine, but after I installed PHP, I'm getting this error message in logs. [Fri Oct 23 21:29:02 2009] [warn] pid file C:/Dev/Apache2.2/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run? Apache service was stopped when installing PHP. I did only one shutdown before instalation via Apache Service Monitor. Deleting httpd.pid and starting again doesn't help. I even tried to lookup process with PID in that file, but there is no such process.

  • Change DPI of one user using W2K3 Remote Desktop / Terminal Server

    - by GvS
    In short: How do I increase the DPI of some (not all) of our customers connected to our RDP server? We are running a W2K3 Terminal Server that our clients connect to to run our application. One of our clients complains that all fonts / icons etc are too small. This user has a high DPI monitor. The DPI of the client OS (XP in this case) is not transferred to the server. To make things worse (or more interesting) the Display properties dialog disables the Advanced button that you can use to change the DPI on normal clients.

  • Linux Server Performance Monitoring

    - by Jon
    I'm looking to monitor performance on my Linux servers (which happen to be Centos). What are the best tools for monitoring things in realtime such as: Disk Performance I/O, swapping etc.. CPU Performance Looking for low level tools, rather than web based tools such as Nagios, Ganglia etc... n.b. I'd like to know exactly what each tool does rather than just having a list of random toolnames if possible please. Why the tool is a better option than others would be good also.

  • Buying replacement Macbook Pro Battery - Genuine vs. eBay

    - by Nicolas Webb
    I'm looking to replace my Macbook Pro's battery (15", last model before the Unibody). It's currently at 55% capacity (as reported in System Information and Battery Health Monitor). I've reset the SMC firmware, calibrated the battery, and it's just not lasting that long anymore. I've seen some genuine replacements that are "pulls" (pulled from used computers) that are rated at least 90% capacity (iFixit, MacSales). I've also seen a variety of batteries on eBay that look more like clones than genuine batteries, but are new. A new battery from Apple is $129, and when I brought my laptop in they ran the Battery test and said if I bought the battery right then they'd give me a discount (around $100). Anyone out there used one of these "OEM Compatible" batteries? Fit/finish good? (I don't want a funky color or a corner that sticks out.) Or, should I just suck it up and get the genuine replacement (for about twice the price)?
