• Editing assemblies using ReflexIL

  - by nmarun

  I have known ReflexIL for quite some time, so I thought I’ll write a line or two about this simple and yet power tool. This tool runs as a plug-in for Red Gate’s Reflector . I’m not sure if I can cover all the features of this tool, but there are a couple that I really liked that we’ll just see those. In order to get it working, you unzip the contents of the file to some folder. In Reflector, under Tools->Add-Ins add the path to the Reflexil.Reflector.dll. And, you’re set. To bring up the add...(read more)

  - by Onaiza

  I am not sure whether this is possible can i have a fan gate between two pages of a website, so that before a visitor can access a particular url it would be mandatory to like our fan page on facebook? Scenario I have a travel website puneritraveller.com, and for each destination featured in the website i have listed hotels, with a direct link to the website of the hotel. for example i have featured a destination 'Alibaug' with a hotels page - puneritraveller.com/alibaug-hotels.html , in this page i have given banner ads for a few hotels for example Yellow house which on clicking redirects to www.yellowhousealibag.com What i want to achieve is, when someone clicks on the banner ad for Yellow house they should be redirected to a page with a like button to facebook.com/puneritraveller and once he/she clicks on the like button should be redirected to www.yellowhousealibag.com Is this possible? Please help

• Generating a twitter OAuth access key - the semi-manual way

  - by Piet

  [UPDATE] Apparently someone at Twitter was listening, or I’m going senile/blind. Let’s call it a combination of both. Instead of following all the steps below, you could just login with the Twitter account you want to use on http://dev.twitter.com, register your application and then click ‘Edit Details’ on the application overview page at http://dev.twitter.com/apps. Next click the ‘Application detail’ button on the right, followed by the ‘My Access Token’ button in order to get your Access Token and Access Token Secret. This makes the old post below rather obsolete. Clearly a case of me thinking everything is a nail and ruby is a hammer (don’t they usually say this about java coders?) [ORIGINAL POST] OAuth is great! OAuth allows your application to use your user’s data without the need to ask for their password. So Twitter made the API much safer for their and your users. Hurray! Free pizza for everyone! Unless of course you’re using the Twitter API for your own needs like running your own bot and don’t need access to other user’s data. In such cases a simple username/password combination is more than enough. I can understand however that the Twitter guys don’t really care that much about these exceptions(?). Most such uses for the API are probably rather spammy in nature. !!! If you have a twitter app that uses the API to access external user’s data: look for another solution. This solution is ONLY meant when you ONLY need access to your own account(s) through the API. Other Solutions Mr Dallas Devries posted a solution here which involves requesting and scraping a one-time PIN. But: I like to minimize the amount of calls I make to twitter’s API or pages to lessen my chances of meeting the fail whale. Also, as soon as the pin isn’t included in a div called ‘oauth_pin’ anymore, this will fail. However, mr Devries’ post was a starting point for my solution, so I’m much obliged to him posting his findings. Authenticating with the Twitter API: old vs new Acessing The Twitter API the old way: require ‘twitter’ httpauth = Twitter::HTTPAuth.new('my_account','my_secret_password') client = Twitter::Base.new(httpauth) client.update(‘Hurray!’) The OAuth way: require 'twitter' oauth = Twitter::OAuth.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY') oauth.authorize_from_access('123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis', 'fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh') client = Twitter::Base.new(oauth) client.update(‘Hurray!’) In the above case, ve4whatafuzzksaMQKjoI is the ‘consumer key’ (sometimes also referred to as ‘consumer token’) and KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY is the ‘consumer secret’. You’ll get these from Twitter when you register your app. 123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis is the ‘access token’ and fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh is the ‘access secret’. This combination gives the registered application access to your account. I’ll show you how to obtain these by following the steps below. (Basically you’ll need a bunch of keys and you’ll have to jump a bit through hoops to obtain them for your server/bot. ) How to get these keys 1. Surf to the twitter apps registration page go to http://dev.twitter.com/apps to register your app. Login with your twitter account. 2. Register your application Enter something for Application name, Description, website,… as I said: they make you jump through hoops. If you plan on using the API to post tweets, Your application name and website will be used in the ‘5 minutes ago via…’ line below your tweet. You could use the this to point to a page with info about your bot, or maybe it’s useful for SEO purposes. For application type I choose ‘browser’ and entered http://www.hadermann.be/callback as a ‘Callback URL’. This url returns a 404 error, which is ideal because after giving our account access to our ‘application’ (step 6), it will redirect to this url with an ‘oauth_token’ and ‘oauth_verifier’ in the url. We need to get these from the url. It doesn’t really matter what you enter here though, you could leave it blank because you need to explicitely specify it when generating a request token. You probably want read&write access so set this at ‘Default Access type’. 3. Get your consumer key and consumer secret On the next page, copy/paste your ‘consumer key’ and ‘consumer secret’. You’ll need these later on. You also need these as part of the authentication in your script later on: oauth = Twitter::OAuth.new([consumer key], [consumer secret]) 4. Obtain your request token run the following in IRB to obtain your ‘request token’ Replace my fake consumer key and consumer secret with the one you obtained in step 3. And use something else instead http://www.hadermann.be/callback: although this will only give a 404, you shouldn’t trust me. irb(main):001:0> require 'oauth' irb(main):002:0> c = OAuth::Consumer.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY', {:site => 'http://twitter.com'}) irb(main):003:0> request_token = c.get_request_token(:oauth_callback => 'http://www.hadermann.be/callback') irb(main):004:0> request_token.token => "UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1" This (UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1) is the request token: Copy/paste this token, you will need this next. 5. Authorize your application surf to https://api.twitter.com/oauth/authorize?oauth_token=[the above token], for example: https://api.twitter.com/oauth/authorize?oauth_token=UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1 This will bring you to the ‘An application would like to connect to your account’- screen on Twitter where you can grant access to the app you just registered. If you aren’t still logged in, you need to login first. Click ‘Allow’. Unless you don’t trust yourself. 6. Get your oauth_verifier from the redirected url Your browser will be redirected to your callback url, with an oauth_token and oauth_verifier parameter appended. You’ll need the oauth_verifier. In my case the browser redirected to: http://www.hadermann.be/callback?oauth_token=UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1&oauth_verifier=waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag Which returned a 404, giving me the chance to copy/paste my oauth_verifier: waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag 7. Request an access token Back to irb, use the oauth_verifier to request an access token, as follows: irb(main):005:0> at = request_token.get_access_token(:oauth_verifier => 'waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag') irb(main):006:0> at.params[:oauth_token] => "123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis" irb(main):007:0> at.params[:oauth_token_secret] => "fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh" We’re there! 123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis is the access token. fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh is the access secret. Try it! Try the following to post an update: require 'twitter' oauth = Twitter::OAuth.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY') oauth.authorize_from_access('123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis', 'fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh') client = Twitter::Base.new(oauth) client.update(‘Cowabunga!’) Now you can go to your twitter page and delete the tweet if you want to.

• Big Data&rsquo;s Killer App&hellip;

  - by jean-pierre.dijcks

  Recently Keith spent  some time talking about the cloud on this blog and I will spare you my thoughts on the whole thing. What I do want to write down is something about the Big Data movement and what I think is the killer app for Big Data... Where is this coming from, ok, I confess... I spent 3 days in cloud land at the Cloud Connect conference in Santa Clara and it was quite a lot of fun. One of the nice things at Cloud Connect was that there was a track dedicated to Big Data, which prompted me to some extend to write this post. What is Big Data anyways? The most valuable point made in the Big Data track was that Big Data in itself is not very cool. Doing something with Big Data is what makes all of this cool and interesting to a business user! The other good insight I got was that a lot of people think Big Data means a single gigantic monolithic system holding gazillions of bytes or documents or log files. Well turns out that most people in the Big Data track are talking about a lot of collections of smaller data sets. So rather than thinking "big = monolithic" you should be thinking "big = many data sets". This is more than just theoretical, it is actually relevant when thinking about big data and how to process it. It is important because it means that the platform that stores data will most likely consist out of multiple solutions. You may be storing logs on something like HDFS, you may store your customer information in Oracle and you may store distilled clickstream information in some distilled form in MySQL. The big question you will need to solve is not what lives where, but how to get it all together and get some value out of all that data. NoSQL and MapReduce Nope, sorry, this is not the killer app... and no I'm not saying this because my business card says Oracle and I'm therefore biased. I think language is important, but as with storage I think pragmatic is better. In other words, some questions can be answered with SQL very efficiently, others can be answered with PERL or TCL others with MR. History should teach us that anyone trying to solve a problem will use any and all tools around. For example, most data warehouses (Big Data 1.0?) get a lot of data in flat files. Everyone then runs a bunch of shell scripts to massage or verify those files and then shoves those files into the database. We've even built shell script support into external tables to allow for this. I think the Big Data projects will do the same. Some people will use MapReduce, although I would argue that things like Cascading are more interesting, some people will use Java. Some data is stored on HDFS making Cascading the way to go, some data is stored in Oracle and SQL does do a good job there. As with storage and with history, be pragmatic and use what fits and neither NoSQL nor MR will be the one and only. Also, a language, while important, does in itself not deliver business value. So while cool it is not a killer app... Vertical Behavioral Analytics This is the killer app! And you are now thinking: "what does that mean?" Let's decompose that heading. First of all, analytics. I would think you had guessed by now that this is really what I'm after, and of course you are right. But not just analytics, which has a very large scope and means many things to many people. I'm not just after Business Intelligence (analytics 1.0?) or data mining (analytics 2.0?) but I'm after something more interesting that you can only do after collecting large volumes of specific data. That all important data is about behavior. What do my customers do? More importantly why do they behave like that? If you can figure that out, you can tailor web sites, stores, products etc. to that behavior and figure out how to be successful. Today's behavior that is somewhat easily tracked is web site clicks, search patterns and all of those things that a web site or web server tracks. that is where the Big Data lives and where these patters are now emerging. Other examples however are emerging, and one of the examples used at the conference was about prediction churn for a telco based on the social network its members are a part of. That social network is not about LinkedIn or Facebook, but about who calls whom. I call you a lot, you switch provider, and I might/will switch too. And that just naturally brings me to the next word, vertical. Vertical in this context means per industry, e.g. communications or retail or government or any other vertical. The reason for being more specific than just behavioral analytics is that each industry has its own data sources, has its own quirky logic and has its own demands and priorities. Of course, the methods and some of the software will be common and some will have both retail and service industry analytics in place (your corner coffee store for example). But the gist of it all is that analytics that can predict customer behavior for a specific focused group of people in a specific industry is what makes Big Data interesting. Building a Vertical Behavioral Analysis System Well, that is going to be interesting. I have not seen much going on in that space and if I had to have some criticism on the cloud connect conference it would be the lack of concrete user cases on big data. The telco example, while a step into the vertical behavioral part is not really on big data. It used a sample of data from the customers' data warehouse. One thing I do think, and this is where I think parts of the NoSQL stuff come from, is that we will be doing this analysis where the data is. Over the past 10 years we at Oracle have called this in-database analytics. I guess we were (too) early? Now the entire market is going there including companies like SAS. In-place btw does not mean "no data movement at all", what it means that you will do this on data's permanent home. For SAS that is kind of the current problem. Most of the inputs live in a data warehouse. So why move it into SAS and back? That all worked with 1 TB data warehouses, but when we are looking at 100TB to 500 TB of distilled data... Comments? As it is still early days with these systems, I'm very interested in seeing reactions and thoughts to some of these thoughts...

• Silverlight for Windows Embedded Tutorial (step 5 and a bit of Windows Phone 7)

  - by Valter Minute

  If you haven’t spent the last week in the middle of the Sahara desert or traveling on a sled in the north pole area you should have heard something about the launch of Windows Phone 7 Series (or Windows Phone Series 7, or Windows Series Phone 7 or something like that). Even if you are in the middle of the desert or somewhere around the north pole you may have been reached by the news, since it seems that WP7S (using the full name will kill my available bandwidth!) is generating a lot of buzz in the development and IT communities. One of the most important aspects of this new platform is that it will be programmed using a new set of tools and frameworks, completely different from the ones used on older releases of Windows Mobile (or SmartPhone, or PocketPC or whatever…). WP7S applications can be developed using Silverlight or XNA. If you want to learn something more about WP7S development you can download the preview of Charles Petzold’s book about it: http://www.charlespetzold.com/phone/index.html Charles Petzold is also the author of “Programming Windows”, the first book I ever read about programming on Windows (it was Windows 3.0 at that time!). The fact that even I was able to learn how to develop Windows application is a proof of the quality of Petzold’s work. This book is up to his standards and the 150pages preview is already rich in technical contents without being boring or complicated to understand. I may be able to become a Windows Phone developer thanks to mr. Petzold. Mr. Petzold uses some nice samples to introduce the basic concepts of Silverlight development on WP7S. On this new platform you’ll use managed code to develop your application, so those samples can’t be ported on Windows CE R3 as they are, but I would like to take one of the first samples (called “SilverlightTapHello1”) and adapt it to Silverlight for Windows Embedded to show that even plain old native code can be used to develop “cool” user interfaces! The sample shows the standard WP7S title header and a textbox with an hello world message inside it. When the user touches the textbox, it will change its color. When the user touches the background (Grid) behind it, its default color (plain old White) will be restored. Let’s see how we can implement the same features on our embedded device! I took the XAML code of the sample (you can download the book samples here: http://download.microsoft.com/download/1/D/B/1DB49641-3956-41F1-BAFA-A021673C709E/CodeSamples_DRAFTPreview_ProgrammingWindowsPhone7Series.zip) and changed it a little bit to remove references to WP7S or managed runtime. If you compare the resulting files you will see that I was able to keep all the resources inside the App.xaml files and the structure of  MainPage.XAML almost intact. This is the Silverlight for Windows Embedded version of MainPage.XAML: <UserControl x:Class="SilverlightTapHello1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phoneNavigation="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Navigation" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="800" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" Width="640" Height="480">   <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneBackgroundBrush}"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions>   <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="SILVERLIGHT TAP HELLO #1" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="main page" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid>   <!--ContentGrid is empty. Place new content here--> <Grid x:Name="ContentGrid" Grid.Row="1" MouseLeftButtonDown="ContentGrid_MouseButtonDown" Background="{StaticResource PhoneBackgroundBrush}"> <TextBlock x:Name="TextBlock" Text="Hello, Silverlight for Windows Embedded!" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Grid> </Grid> </UserControl> If you compare it to the WP7S sample (not reported here to avoid any copyright issue) you’ll notice that I had to replace the original phoneNavigation:PhoneApplicationPage with UserControl as the root node. This make sense because there is not support for phone applications on CE 6. I also had to specify width and height of my main page (on the WP7S device this will be adjusted by the OS) and I had to replace the multi-touch event handler with the MouseLeftButtonDown event (no multitouch support for Windows CE R3, still). I also changed the hello message, of course. I used XAML2CPP to generate the boring part of our application and then added the initialization code to WinMain: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { if (!XamlRuntimeInitialize()) return -1;   HRESULT retcode;   IXRApplicationPtr app; if (FAILED(retcode=GetXRApplicationInstance(&app))) return -1; XRXamlSource dictsrc;   dictsrc.SetResource(hInstance,TEXT("XAML"),IDR_XAML_App);   if (FAILED(retcode=app->LoadResourceDictionary(&dictsrc,NULL))) return -1;   MainPage page;   if (FAILED(page.Init(hInstance,app))) return -1;   UINT exitcode;   if (FAILED(page.GetVisualHost()->StartDialog(&exitcode))) return -1;   return exitcode; }   You may have noticed that there is something different from the previous samples. I added the code to load a resource dictionary. Resources are an important feature of XAML that allows you to define some values that could be replaced inside any XAML file loaded by the runtime. You can use resources to define custom styles for your fonts, backgrounds, controls etc. and to support internationalization, by providing different strings for different languages. The rest of our WinMain isn’t that different. It creates an instances of our MainPage object and displays it. The MainPage class implements an event handler for the MouseLeftButtonDown event of the ContentGrid: class MainPage : public TMainPage<MainPage> { public:   HRESULT ContentGrid_MouseButtonDown(IXRDependencyObject* source,XRMouseButtonEventArgs* args) { HRESULT retcode; IXRSolidColorBrushPtr brush; IXRApplicationPtr app;   if (FAILED(retcode=GetXRApplicationInstance(&app))) return retcode;   if (FAILED(retcode=app->CreateObject(IID_IXRSolidColorBrush,&brush))) return retcode;   COLORREF color=RGBA(0xff,0xff,0xff,0xff);   if (args->pOriginalSource==TextBlock) color=RGBA(rand()&0xFF,rand()&0xFF,rand()&0xFF,0xFF);   if (FAILED(retcode=brush->SetColor(color))) return retcode;   if (FAILED(retcode=TextBlock->SetForeground(brush))) return retcode; return S_OK; } }; As you can see this event is generated when a used clicks inside the grid or inside one of the objects it contains. Since our TextBlock is inside the grid, we don’t need to provide an event handler for its MouseLeftButtonDown event. We can just use the pOriginalSource member of the event arguments to check if the event was generated inside the textblock. If the event was generated inside the grid we create a white brush,if it’s inside the textblock we create some randomly colored brush. Notice that we need to use the RGBA macro to create colors, specifying also a transparency value for them. If we use the RGB macro the resulting color will have its Alpha channel set to zero and will be transparent. Using the SetForeground method we can change the color of our control. You can compare this to the managed code that you can find at page 40-41 of Petzold’s preview book and you’ll see that the native version isn’t much more complex than the managed one. As usual you can download the full code of the sample here: http://cid-9b7b0aefe3514dc5.skydrive.live.com/self.aspx/.Public/SilverlightTapHello1.zip And remember to pre-order Charles Petzold’s “Programming Windows Phone 7 series”, I bet it will be a best-seller!

Here's what I've tried and the outcomes: assign icache_ram_rw = 1'b0; ( declarative lvalue or port sink reg icache_ram_rw must be a wire ) icache_ram_rw <= 1'b0; ( instance gate/name for type "icache_ram_rw" expected - <= read ) How do I do it after all?!

• How to safely store encryption key in a .NET assembly

  - by Alex

  In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?

  I'm reading about Red Gate SQL Backup, and I liked the concept of creating a database backup compressed and writing on disk the compressed backup directly without an intermediate SQL Server native backup. And I'm wondering how this type of software make backups. It accesses the database files directly? It uses some sort of SQL Server or Windows API? Windows Shadow Copy?

• High Load mysql on Debian server

  - by Oleg Abrazhaev

  I have Debian server with 32 gb memory. And there is apache2, memcached and nginx on this server. Memory load always on maximum. Only 500m free. Most memory leak do MySql. Apache only 70 clients configured, other services small memory usage. When mysql use all memory it stops. And nothing works, need mysql reboot. Mysql configured use maximum 24 gb memory.

• Blank black screen with cursor after login -- RHEL5

  - by Sean O.

  I have a RHEL 5 machine here which is a Dell Precision T3500. I'm an Ubuntu guy, but I'm having a heck of a time with this machine. After processing its first security update, we cannot log in via the gdm greeter. A new kernel was installed; then I installed the nVidia drivers for our Quadro NVS 295. I know the X configuration is valid because the gdm greeter does display; however, upon login all we can get is a blank, black screen with a cursor. I thought perhaps our python installation was corrupted but a reinstall via yum has not helped. I have searched & googled extensively for a potential fix for this and can find nothing. Below are outputs from uname, a tail of an error in /var/log/messages, and the Xorg.conf. Can anyone suggest a course of action?

• VPN with wrong subnet mask

  - by Philipp Schmid

  I followed these instructions on www.hottonetworking.com to set up VPN on a clean install of Windows Server 2008 SP2 (not R2 yet). When I then establish a VPN connection to that machine from a client machine (running Windows 7 RC), everything succeeds (it seems since I get a 'Connected' state in the network sharing center window), but I end up with a subnet mask (according to ipconfig /all) of 255.255.255.255 instead of 255.255.255.0. The net effect is that I don't have local network or internet capability. What additional configuration steps do I have to do to get VPN with the proper subnet mask working? Update: Using the steps outlined in the Technet article mentioned by Mr. Nimble, I was able to get internet connection. Apparently the subnet mask is not an issue as my coworker was able to connect using his VPN connection and ping the server machine by name as well.

• How does DNS "get stuck"?

  - by Muhammad Mussnoon

  I recently registered a domain and got hosting from Dreamhost. But when even after three days, the website was not accessible, I contacted support about it. This is the response the support person gave me: "My apologies! The DNS had gotten stuck, so I went ahead and pushed that through for you. Please allow 2-3 hours for the DNS to propagate." Now I have to say that my knowledge regarding these things is virtually zero, and I couldn't understand what the support person meant, so I ran a search and it seemed that Mr. Google knew just as much as I did regarding this. Can someone tell me what "dns getting stuck" means?

• How can I speed up my Windows Server 2008 VPN Connection?

  - by Pure.Krome

  So I've installed VPN service that comes with Windows Server 2008. Works perfectly, etc. When a client remote desktops to one of the private servers at the office, via VPN .. it's pretty slow. Now - how long is a piece of string? So before I get all the obligatory checks, I'll list the things from Mr. Obvious: Our modem/router (fritz!box) has a data/graph that shows incoming and outbound bandwidth. Both directions are barely getting used when a client has RDP'd via VPN. Our office internet connection is running at 21,9 Mbit/s download 1,3 Mbit/s upload. I feel like it's maxing at .. modem speeds ?? Is there any tricks I can do to confirm this and possibly even fix this?

• Address bar in Finder?

  - by wag2639

  I'm used to knowing where all my files are (and I'm anal about it -- I don't need Mr Jobs thinking he knows best about where my files should go). Is there a way to get an address bar to show up in Finder in OSX (10.5+) like in Explorer in Windows or Nautilus in Gnome. Edit: I also want to be able to copy the address bar. Perhaps the workflow is different on a Mac, but I'm use to throughly sorting my files under many layers of folders and then when I need to upload or download something, or access a file in command line or etc, I can copy and paste that directly into the file dialog. To clarify, my goal is to have an experience like in Windows: press Ctrl + D (CMD + L) and Ctrl + C.

• Various problems with software raid1 array built with Samsung 840 Pro SSDs

  - by Andy B

  I am bringing to ServerFault a problem that is tormenting me for 6+ months. I have a CentOS 6 (64bit) server with an md software raid-1 array with 2 x Samsung 840 Pro SSDs (512GB). Problems: Serious write speed problems: root [~]# time dd if=arch.tar.gz of=test4 bs=2M oflag=sync 146+1 records in 146+1 records out 307191761 bytes (307 MB) copied, 23.6788 s, 13.0 MB/s real 0m23.680s user 0m0.000s sys 0m0.932s When doing the above (or any other larger copy) the load spikes to unbelievable values (even over 100) going up from ~ 1. When doing the above I've also noticed very weird iostat results: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 1589.50 0.00 54.00 0.00 13148.00 243.48 0.60 11.17 0.46 2.50 sdb 0.00 1627.50 0.00 16.50 0.00 9524.00 577.21 144.25 1439.33 60.61 100.00 md1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 0.00 1602.00 0.00 12816.00 8.00 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 And it keeps it this way until it actually writes the file to the device (out from swap/cache/memory). The problem is that the second SSD in the array has svctm and await roughly 100 times larger than the second. For some reason the wear is different between the 2 members of the array root [~]# smartctl --attributes /dev/sda | grep -i wear 177 Wear_Leveling_Count 0x0013 094% 094 000 Pre-fail Always - 180 root [~]# smartctl --attributes /dev/sdb | grep -i wear 177 Wear_Leveling_Count 0x0013 070% 070 000 Pre-fail Always - 1005 The first SSD has a wear of 6% while the second SSD has a wear of 30%!! It's like the second SSD in the array works at least 5 times as hard as the first one as proven by the first iteration of iostat (the averages since reboot): Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 10.44 51.06 790.39 125.41 8803.98 1633.11 11.40 0.33 0.37 0.06 5.64 sdb 9.53 58.35 322.37 118.11 4835.59 1633.11 14.69 0.33 0.76 0.29 12.97 md1 0.00 0.00 1.88 1.33 15.07 10.68 8.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 1109.02 173.12 10881.59 1620.39 9.75 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.41 0.01 3.10 0.02 7.42 0.00 0.00 0.00 0.00 What I've tried: I've updated the firmware to DXM05B0Q (following reports of dramatic improvements for 840Ps after this update).

Or maybe sdb is doing also something else besides what sda does. Is there some way to find out if sdb is doing more than what sda does? UPDATE Again, as suggested by Mr. Wagner, I have swapped the 2 SSDs. And as he thought it would happen, the problem moved from sdb to sda. So I guess I'll RMA one of the SSDs. I wonder if the cage might be problematic. What is wrong with this array? Please help!
