  • Is there a simple way to convert MySQL data into Title Case?

    - by john.designop.us
    I have a MySQL table where all the data in one column was entered in UPPERCASE, but I need to convert in to Title Case, with recognition of "small words" akin to the Daring Fireball Title Case script. I found this excellent solution for transforming strings to lowercase, but the Title Case function seems to have been left out of my version of MySQL. Is there an elegant way to do this?

  • Managing Cisco programatically; Telnet vs SNMP?

    - by MikeHerrera
    I was recently approached by a network-engineer, co-worker who would like to offload his minor network admin duties to a junior-level helpdesk tech. The specific location in need of management acts as an ISP for tenants on its single-site property, so there's a lot of small adjustments being made on a daily basis. I am thinking it would be helpful to write him a winform app to manage the 32 Cisco devices, on-site. I'd like to initially provide functionality which could modify access control lists, port VLAN assignments, and bandwidth limitations per VLAN... adding more to the list as its deemed valuable. My initial thought was to emulate a telnet session with the network device; utilizing my network-engineer's familiarity with the command-line / IOS interaction. Minimal time would be required to learn Cisco IOS conventions, myself. Though while searching for solutions, it appears that most people favor SNMP. That, or, their specific circumstances pushed them in the direction of SNMP. I wanted to know if I've overlooked an obvious benefit of SNMP. Should I be using SNMP? Why or why not?

  • How to do Basic Authentication using FireWatir on Ubuntu Linux?

    - by lotharsmash
    Hi, I'm trying to use FireWatir (1.6.5) to access a site using Basic Authentication and I've been unable to find a solution that works on Firefox in Linux. Does FireWatir 1.6.5 support Basic Authentication on Linux? I've been searching the web for 2 days and can't get a straight answer anywhere as to how to do this. The only thread I found that seemed helpful was this one ( http://groups.google.com/group/watir-general/browse_thread/thread/d8ab9a177d282ce4/fc1bf2319fb387d8?lnk=gst&q=basic+authentication#fc1bf2319fb387d8). Aedorn Varanis says " Angrez's fork had the solution so I'm using that now. Thanks Angrez, works perfectly!", but he doesn't mention what he did to get things working. Initially I tried to bypass the authentication dialog box by using: browser.goto('http://admin:[email protected]') However, this generates a "Confirm" dialog which says: "You are about to log in to the site "172.20.1.1" with the username "admin"." [Cancel, OK] This dialog blocks, and the goto call won't return until I click "OK". Then I tried adding: browser.startClicker("ok") browser.goto('http://admin:[email protected]') But this ALSO generates the same "Confirm" dialog. I tested out the startClicker functionality using the unit test /var/ lib/gems/1.8/gems/firewatir-1.6.5/unittests/html/JavascriptClick.html and it worked fine, which makes me think that using the startClicker method is NOT the correct way to take care of the Confirm dialog. Anybody else found a way to get Basic Auth to work, or how to click the OK on the confirm dialog? I'm at my wits end...

  • Running Hadoop example in psuedo-distributed mode on vm

    I have set-up Hadoop on a OpenSuse 11.2 VM using Virtualbox.I have made the prerequisite configs. I ran this example in the Standalone mode successfully.

  • Padding is invalid and cannot be removed

    - by Ajay
    I have hosted an asp.net 2.0 site. Everyday, i am getting an error "Padding is invalid and cannot be removed" 2-3 times. Backend used is sql server 2005. the site is controlled via plesk 9.2 CP. Pooling is enabled with timeout as 120 Minutes, in IIS. Can it be the reason for this? I have not used any encryption except for the stored passwords(MD5) The error message is : " Base Exception = : Padding is invalid and cannot be removed. - Source : System.Web - TargetSite :Void ThrowError(System.Exception, System.String, System.String, Boolean)Message : Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

  • ActiveRecord + CodeIgniter - Return single value from query, not in array form.

    - by txmail
    Say you construct an activerecord query that will always just return a single value, how do you just address that single value instead of getting an array in return? For instance I am using an ActiveRecord query to return the SUM of a single column, it will only return this one single SUM, instead of having to parse the array is there a way to assign the value as a function return equal to that value instead of getting an array?

  • HTML5 <video> callbacks?

    - by Andrew
    I'm working on a site for a client and they're insistent on using HTML5's video tag as the delivery method for some of their video content. I currently have it up and running with a little help from http://videojs.com/ to handle the Internet Explorer Flash fallback. One thing they've asked me to do is, after the videos finish playing (they're all a different length), fade them out and then fade a picture in place of the video --- think of it like a poster frame after the video. Is this even possible? Can you get the timecode of a currently playing movie via Javascript or some other method? I know Flowplayer (http://flowplayer.org/demos/scripting/grow.html) has an onFinish function, is that the route I should take in lieu of the HTML5 video method? Does the fact that IE users will be getting a Flash player require two separate solutions? Any input would be greatly appreciated. I'm currently using jQuery on the site, so I'd like to keep the solution in that realm if at all possible. Thanks!

  • Source for Names to use in web scraping

    - by PyNEwbie
    Can anyone suggest a good source of names that I can use to help analyze some tables on web pages. The first column of the tables I am scraping have names alone, names and titles or just titles. The names can be as varied as John Smith to Vikram Saksena. I have been poking around for a compiled list of words that can be found in proper names.

  • Simple .HTACCESS Passing Variables

    - by Willie Murray III
    Let's says I have a classifieds site which has a URL structure similar to the one which I have listed below: Ex. http://takarat.com/openclassifieds/?category=iphone&location=tennessee This is what shows up when I click "tennessee" as the location and then click on "iphone" as the category. Now let's say this site has a search box and I wanted a URL which comes up after using this search box to show up as opposed to the previous URL. Let's say that whenever I search for the word "iphone" while WITHIN the iphone CATEGORY the following link shows up: Iphone SEARCH Ex. http://takarat.com/openclassifieds/?s=iphone&category=iphone&location=tennessee Ok, I want THAT iphone SEARCH to come up whenever anyone clicks Tennessee Iphone..How would I do this [by the way, I want this to be dynamic so that I can use the code for different combinations of locations and products etc..I want the code to use the CATEGORY name to conduct the search basically]? I believe that this will involve "Passing varibles" from the original link... I am new to programming so I may have my terminology wrong. Any help would be appreciated. Thanks in advance. TURN THIS: takarat.com/openclassifieds/?category=iphone[var 1]&location=tennessee[var2] INTO THIS: takarat.com/openclassifieds/?s=iphone[var 1]&category=iphone[var 1]&location=tennessee[var2]

  • MySQL table partitioning qn:

    - by JVXR
    I have a table (innodb) that will have billions of records eventually. Every 2nd week I expect ~ 500K records to get dropped into the table. I would want to partition this table based on the date on which the data is imported - luckily this is a field in the table that is of the format yyyy-mm-dd - Is it possible to partition it based on this date column ? I tried looking at the 18th chapter of mysql docs but couldn't figure out if this is possible. -tia

  • How can a not null constraint be dropped?

    - by Tomislav Nakic-Alfirevic
    Let's say there's a table created as follows: create table testTable ( colA int not null ) How would you drop the not null constraint? I'm looking for something along the lines of ALTER TABLE testTable ALTER COLUMN colA DROP NOT NULL; which is what it would look like if I used PostgreSQL. To my amazement, as far as I've been able to find, the MySQL docs, Google and yes, even Stackoverflow (in spite of dozens or hundreds of NULL-related questions) don't seem to lead towards a single simple SQL statement which will do the job.

  • Ajax / Internet Explorer Encoding problem

  • Accessing a file on a network drive

    - by Rekreativc
    Hello. Background: I have an application that has to read from files on a network drive (Z:) This works great in my office domain, however it does not work on site (in a different domain). As far as I can tell the domain users and network drives are set in the same way, however I do not have access to users etc in the customers domain. When I couldn't access the network drive I figured I needed a token for a user. This is how I impersionate the user: [DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); ... const string userName = "Razvoj02"; const string pass = "Programer02"; const string domainName = null; const int LOGON32_PROVIDER_DEFAULT = 0; const int LOGON32_LOGON_INTERACTIVE = 2; IntPtr tokenHandle = new IntPtr(0); bool returnValue = LogonUser(userName, domainName, pass, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref tokenHandle); if (!returnValue) throw new Exception("Logon failed."); WindowsImpersonationContext impersonatedUser = null; try { WindowsIdentity wid = new WindowsIdentity(tokenHandle); impersonatedUser = wid.Impersonate(); } finally { if (impersonatedUser != null) impersonatedUser.Undo(); } Now here is the interesting/weird part. In my network the application can already access the network drive, and if I try to impersonate the active user (exactly the same user, including the same domain) it will not be able to access the network drive. This leaves me helpless since now I have no idea what works and what doesn't, and more to the point, will it work on site? What am I missing?

  • WPF - How do I get an object that is bound to a ListBoxItem back

    - by JonBlumfeld
    Hi there here is what I would like to do. I get a List of objects from a database and bind this list to a ListBox Control. The ListBoxItems consist of a textbox and a button. Here is what I came up with. Up to this point it works as intended. The object has a number of Properties like ID, Name. If I click on the button in the ListBoxItem the Item should be erased from the ListBox and also from the database... <ListBox x:Name="taglistBox"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="HorizontalAlignment" Value="Stretch"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <ContentPresenter HorizontalAlignment="Stretch"/> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="Tag" Value="{Binding TagSelf}"></Setter> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Grid HorizontalAlignment="Stretch"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Button Grid.Column="0" Name="btTag" VerticalAlignment="Center" Click="btTag_Click" HorizontalAlignment="Left"> <Image Width="16" Height="16" Source="/WpfApplication1;component/Resources/104.png"/> </Button> <TextBlock Name="tbtagBoxTagItem" Margin="5" Grid.Column="1" Text="{Binding Name}" VerticalAlignment="Center" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The Textblock.Text is bound to object.Name and the ListBoxItem.Tag to object.TagSelf (which is just a copy of the object itself). Now my questions If I click the button in the listboxItem how do I get the listboxitem and the object bound to it back. In order to delete the object from the database I have to retrieve it somehow. I tried something like ListBoxItem lbi1 = (ListBoxItem)(taglistBox.ItemContainerGenerator.ContainerFromItem(taglistBox.Items.CurrentItem)); ObjectInQuestion t = (ObjectInQuestion) lbi1.Tag; Is there a way to automatically update the contents of the ListBox if the Itemssource changes? Right now I'm achieving that by taglistBox.ItemsSource = null; taglistBox.ItemsSource = ObjectInQuestion; I'd appreciate any help you can give :D Thanks in advance

  • ai: Determining what tests to run to get most useful data

    - by Sai Emrys
    This is for http://cssfingerprint.com I have a system (see about page on site for details) where: I need to output a ranked list, with confidences, of categories that match a particular feature vector the binary feature vectors are a list of site IDs & whether this session detected a hit feature vectors are, for a given categorization, somewhat noisy (sites will decay out of history, and people will visit sites they don't normally visit) categories are a large, non-closed set (user IDs) my total feature space is approximately 50 million items (URLs) for any given test, I can only query approx. 0.2% of that space I can only make the decision of what to query, based on results so far, ~10-30 times, and must do so in <~100ms (though I can take much longer to do post-processing, relevant aggregation, etc) getting the AI's probability ranking of categories based on results so far is mildly expensive; ideally the decision will depend mostly on a few cheap sql queries I have training data that can say authoritatively that any two feature vectors are the same category but not that they are different (people sometimes forget their codes and use new ones, thereby making a new user id) I need an algorithm to determine what features (sites) are most likely to have a high ROI to query (i.e. to better discriminate between plausible-so-far categories [users], and to increase certainty that it's any given one). This needs to take into balance exploitation (test based on prior test data) and exploration (test stuff that's not been tested enough to find out how it performs). There's another question that deals with a priori ranking; this one is specifically about a posteriori ranking based on results gathered so far. Right now, I have little enough data that I can just always test everything that anyone else has ever gotten a hit for, but eventually that won't be the case, at which point this problem will need to be solved. I imagine that this is a fairly standard problem in AI - having a cheap heuristic for what expensive queries to make - but it wasn't covered in my AI class, so I don't actually know whether there's a standard answer. So, relevant reading that's not too math-heavy would be helpful, as well as suggestions for particular algorithms. What's a good way to approach this problem?
