  • How can I restore a corrupted Shotwell db?

    - by Yann Dìnendal
    While I was importing photos from a SD card in Shotwell, my laptop has crashed (shutdown because of over-heating). Now, I can no longer launch Shotwell: $ shotwell ** ERROR:x86_64-linux-gnu/db/VersionTable.c:104:version_table_construct: assertion failed: (res == SQLITE_OK) If I move the .db file ~/.shotwell/data/photo.db elsewhere so it is no longer present (but backed-up), shotwell will launch, but will rebuild its library, which will be empty. I can re-import the folders shotwell creates, but I lose nearly all meta-data (most importantly the "folders", or events, and their main picture) Is there a way to repair/rebuild/restore photo.db? How can I see what's inside? how bad it's damaged? Or is there another way to get back my events and imports?

  • Inline Image in ASP.NET

    - by Ricardo Peres
    Inline images is a technique that, instead of referring to an external URL, includes all of the image’s content in the HTML itself, in the form of a Base64-encoded string. It avoids a second browser request, at the cost of making the HTML page slightly heavier and not using cache. Not all browsers support it, but current versions of IE, Firefox and Chrome do. In order to use inline images, you must write the img element’s src attribute like this: 1: <img src="data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub/ 2: /ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcpp 3: V0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7" 4: width="16" height="14" alt="embedded folder icon"/> The syntax is: data:[<mediatype>][;base64],<data> I developed a simple control that allows you to use inline images in your ASP.NET pages. Here it is: 1: public class InnerImage: Image 2: { 3: protected override void OnInit(EventArgs e) 4: { 5: String imagePath = this.Context.Server.MapPath(this.ImageUrl); 6: String extension = Path.GetExtension(imagePath).Substring(1); 7: Byte[] imageData = File.ReadAllBytes(imagePath); 8:  9: this.ImageUrl = String.Format("data:image/{0};base64,{1}", extension, Convert.ToBase64String(imageData)); 10:  11: base.OnInit(e); 12: } 13: } Simple, don’t you think?

  • What is the best way to work with large databases in Java depending on context?

    - by Singletony
    Hi guys. We are trying to figure out the best practice for working with very large DBs in Java. What we do is a kind of BI, i.e analyzing very large DBs, and using them to create intermediate DBs that represent intelligent knowledge of the DBs. We are currently using JDBC, and just preforming queries using a ResultSet. As more and more data is being created, we are wondering whether more appropriate ways exist for parsing and manipulating these large DBs: We need to support 'chunk' manipulation and not an entire DB at once(e.g. limit in JDBC, very poor performance) We do not need to be constantly connected since we are just pulling results and creating new tables of our own. We want to understand JDBC alternatives, with respect to advantages and disadvantages. Whether you think JDBC is the way to go or not, what are the best practices to go by depending on context (e.g. for large DBs queried in chunks) ? If my question is not clear, I will gladly elaborate! THANK YOU SO MUCH!

  • CRM + Invoicing/Billing + Ticketing for a small web design company

    - by Mike
    Hi everyone, I am currently using ActiveCollab but it lacks the typical CRM features. I can't even keep notes about a customer saved in one place. What I am looking for is a simple but efficient CRM application that allows me to store all the (potential) customers along with their phone calls noted down, contracts, agreements. On the billing end, I should be able to keep track of invoices and payments, along with a bit of sales reports. A great extra would be a ticket support feature but not really necessary I looked at VTiger and SugarCRM at first. Though, they look too complex on the sales/campaigns end but completely lack the billing side. Do you have some good apps/services to suggest? :) Any programming language or OS would do. Both paid and free. Thanks Mike

  • How to represent a tree structure in NoSQL

    - by Vlad Nicula
    I'm new to NoSQL and have been playing around with a personal project on the MEAN stack (Mongo ExpressJs AngularJs NodeJs). I'm building a document editor of sorts that manages nodes of data. Each document is actually a tree. I have a CRUD api for documents, to create new trees and a CRUD api for nodes in a given document. Right now the documents are represented as a collection that holds everything, including nodes. The children parent relationship is done by ids. So the nodes are an map by id, and each node has references to what nodes are their children. I chose this "flat" approach because it is easier to get a node by id from a document. Being used to having a relation table between nodes and documents, a relation table between nodes and children nodes I find it a bit weird that I have to save the entire "nodes" map each time I update a node. Is there a better way to represent such a data type in NoSQL?

  • dynamic urls and links on one web page

    - by John
    I am trying to figure out how to create dynamic links and urls on a static webpage. What I want to do is the following: I have a single webpage for example: MYWEBPAGEdotCOM/INDEX.HTML that will always look the same, except for one link on the page. the link would be on the page for example: LINK TO AFFILIATE: affiliatedotCOM/my-affiliate_code_here_DYNAMIC_REFERER the only thing would change is the "DYNAMIC_REFERER" with every dynamic url on this page: MYWEBPAGEdotCOM/INDEX.PHP_id=test1 MYWEBPAGEdotCOM/INDEX.PHP_id=test2 MYWEBPAGEdotCOM/INDEX.PHP_id=test3 MYWEBPAGEdotCOM/INDEX.PHP_id=test4 which would only hange the dynamic link on the page to: affiliatedotCOM/my-affiliate_code_here_test1 affiliatedotCOM/my-affiliate_code_here_test2 affiliatedotCOM/my-affiliate_code_here_test3 affiliatedotCOM/my-affiliate_code_here_test4 Can someone tell me how I could go about doing this? I just dont want to have to make 100's of pages, as this would prevent me from having to do so.

  • Robots.txt practices with .htaccess redirections (inherits)

    - by Jayhal
    I have a question regarding how to write robots.txt files for many domains and subdomains with redirects in place. We have a hosting account that enacts primary and add-on domains. All of our domains and subdomains, including the primary domain, is redirected via htaccess 301s to their own subdirectories in the primary domain's root directory. I'm confused about how I would write the robots.txt for certain directories. First, I wanted to confirm I am right in understanding that for domains and subdomains, crawlers will look to the directory that acts as that urls root directory for the crawling rules(robots.txt). Also, that a directory will not be affected by a robots.txt present in their parent directory if the directory has its own domain/subdomain, and that url is the one being accessed by crawlers. (Am pretty sure, but I wanted to confirm I didnt have a fundamentally flawed understanding of robots.txt) In the original root directory on the account(where the primary domain was directed before htaccess was put in place) what should the robots.txt contain? When crawlers look to crawl our primary domain, will they look to the original root directory for the robots.txt or will they reference the file contained in the new subdirectory where all the primary domain's site files are located? If so, what should the root's robot.txt include if anything at all. Would I be right to include a simple 'disallow: /' for all agents, and then include more specific robots.txt files in each subdirectory with more specific instructions. Would that affect the crawling of the directory where the primary domain is now redirected? Any help is greatly appreciated, Thanks!

  • Is dynamic HTML layout good from an SEO perspective?

    - by sll
    Just wondering whether dynamically built HTML layout is fine from SEO perspectives? So let's assume e-commerce engine and its most popular page - products catalog. So 90% of the page is built using AJAX and MVVM library knockoutjs which builds HTML on the fly on the client side. So how search bots would parse such content? Is it fine indexed and would be such effective as server-side built HTML pages from the SEO perspectives?

  • I want to install and get to building a personal MySQL DB

    - by Ari Hall
    So how do I go from installing MySQL from the Software Center to inputing data into fields and bringing in a comma delimited file? I've only had brief experience with MSAccess and OOo Base a long time ago, so details are appreciated, I just want to get up and running. I have Ubuntu 10.10, 64 bit, if that affects much. If you can link me to a howto that does exactly what I'm looking for, that would work. Again, Thanks!

  • Useful code paste site tools

    - by acidzombie24
    I know there are site tools to check if your webpage is alive, has compression, etc but lets not get into that. What are useful sites to paste code in and to share links of? The three i know are http://codepad.org/ shows source and runs code online http://www.pastie.org/ share source with syntax highlighting http://jsfiddle.net/ great for JS help or for the occasional test. What else do you know of? One answer per question. I'll let lints and validators slide since you do paste code into them. Mention a weakness if you do know one so others wont be surprised or disappointed.

  • GWT: reporting crawling errors for non existing links

    - by pixeline
    Google Webmaster Tools is reporting crawl errors for links that never existed, and if i check the "Linked from" tab for a given error link, it shows another that never existed. They all mention joomla/ which is not the cms used on this domain (it's wordpress fyi). Exampled: http://example.com/joomla/index.php/component/user/register Linked from: http://example.com/joomla/component/user/login?return=L2###### What is going on? UPDATE 1 I tried something: I provided one of the faulty urls to the "Fetch as Google" functionality. Instead of returning a 404, it returns a 301 to another Joomla page.

  • SSRS/Sharepoint - Reports made in Report Builder not being list in Sharepoint Web Part

    I followed the steps here to integrate reporting services with sharepoint in native mode. I made a page in Sharepoint with the report explorer web part and everything is working. The issue is when I create a report with the web based report builder tool, it will show up in the report manager page, but not show up in the report explorer web part on the share point page. New reports I upload using report manager do show up. Does anyone have any ideas? I'm really stuck.

  • Permissions & File Structure w/ nginx & multiple sites

    - by Michael
    I am using nginx for the first time as a long time Apache user. I setup a Linode to test everything and to eventually port over my websites. Previously I had /home/user/www (wwwroot) I am looking at doing something similar with /srv/www/domain/www (wwwroot) Rather than using /srv/domain (wwwroot), the reason is many of the sites are WordPress and one of the things I do for security is to move the config file one level above wwwroot and can't have multiple configuration files from multiple domains in the same top level folder. Since I own all the sites, I wasn't going to create a user for each domain. My user is a member of www-data and was going to use 2770 for www and have domain/www for each new domain. www would be owned by group www-data. Is this the best way to handle this?

  • DNS - domain conflict?

    - by Stefanos.Ioannou
    I was given two domains: domain.com & domain.info (they are on GoDaddy). And I was also given two servers, 107.105.38.99 - Rails app and 107.107.90.17 - Wordpress platform, on Digital Ocean. At first, I was instructed to associate domain.com with the 107.107.38.99 (Rails app). Then I was instructed to de-associate this IP with domain.com and associated the 107.107.90.17 with the domain name domain.com. Then I was instructed to associated domain.info with the 107.107.38.99 (Rails app). Right now, when I go to domain.com the WordPress platform (107.107.90.17) loads fine and that is what is expected. But when I go to domain.info for the Rails app (107.107.38.99) I get redirected to domain.com. This is not expected and this is really weird for me. When I ping domain.info I get this: PING domain.info (107.107.38.99): 56 data bytes 64 bytes from 107.107.38.99: icmp_seq=0 ttl=50 time=74.601 ms Which is the expected result showing the correct IP but I don't understand why I get redirected to domain.com...(which when I ping is:) domain 64 bytes from 107.107.90.17: icmp_seq=0 ttl=50 time=75.057 ms The PTR Records on Digital Ocean are as follows: IP Address PTR Record 107.107.38.99 domain.info. 107.107.90.17 domain.com. and the DNS configurations on Digital Ocean are: domain.com A: @ 107.107.90.17 CNAME: * @ domain.info A: @ 107.107.38.99 CNAME: * @ I am not sure what the issue is, if you have any clue please let me know, I will be really grateful. If you need any other info let me know.

  • Can AJAX in a CMS slow down your server

    - by Saif Bechan
    I am currently developing some plugins for WordPress, and I was wondering which route to take. Let's take an example, you want to display the last 3 tweets on your page. Option 1 You do things the normal way inside WordPress. Someone enters the website, while generating the page, you fetch the tweets in php via the twitter api, and just display them where you want. Now the small problem with this is, that you have to wait for the response from twitter. This takes a few ms. NO real problem, but this is question is just out of curiosity. Option 2 Here you don't do anything in WordPress on the initial load, but you do have the API inside. Now you just generate the page, and as soon as the page is done on the client side, you do a small AJAX call back to the server via a WordPress plugin, to fetch your latest tweets. Also called asynchronously. Now the problem with this IMO is that you have much more stress on your server. For starters you have two HTTP requests instead of one. Secondly the WordPress core has to load two times instead of one. Other options Now I know there are a lot of other options: 1) Getting the tweets directly via javascript, no stress on the server at all. 2) Cache the tweets so they are fetched from the DB instead of using the API every time. 3) Getting the tweets from an ajax call that is not a WordPress plugin. 4) Many more. My Question Now my question is if you only compare 1 and 2, which would be a better choice.
