  • Les mardis sont les journées les plus dangereuses en ligne, une étude révèle les pics de prolifération des différentes menaces du Web

    Les mardis sont les journées les plus dangereuses en ligne, une étude révèle les pics de prolifération des différentes menaces du Web Une étude menée par SonicWall a révélé des conclusions surprenantes. Le mardi serait la pire journée pour les menaces informatiques, ce serait ces jours là que les plus hauts taux de trafic en lien avec des actions malveillantes seraient enregistrés, et ce, dans le monde entier. Juste derrière, viendrait le lundi, lui aussi animé pour de nombreux exploits et attaques. En revanche, la pire journée à l'échelle britannique se trouve être le vendredi, tout du moins en novembre 2010 (mois dont les données ont été analysées pour obtenir ce résultat). La période ...

  • Firefox s'acharne contre les plug-ins périmés et avertit plus sérieusement ses utilisateurs pour les mettre à jour

    Firefox s'acharne contre les plug-ins périmés Et avertit plus sérieusement ses utilisateurs pour les mettre à jour Les utilisateurs de Firefox risquent à l'avenir d'être harcelés par les notifications de mises à jour fréquentes des plug-ins périmés, ces sources inépuisables de problèmes de sécurité. En effet, Firefox compte appeler plus fermement à l'installation de ces mises à jour, et ce à partir de chaque page qui y fait appel, alors qu'il faut actuellement aller expressément sur le gestionnaire des extensions. Selon les développeurs de Firefox, cela concerne les versions obsolètes de Silverlight, Adobe Reader, Adobe Flash et autres, mais cette vérification n'est disponible pour le mom...

  • Wisdom of merging 100s of Oracle instances into one instance

    - by hoytster
    Our application runs on the web, is mostly an inquiry tool, does some transactions. We host the Oracle database. The app has always had a different instance of Oracle for each customer. A customer is a company which pays us to provide our service to the company's employees, typically 10,000-25,000 employees per customer. We do a major release every few years, and migrating to that new release is challenging: we might have a team at the customer site for a couple weeks, explaining new functionality and setting up the driving data to suit that customer. We're considering going multi-client, putting all our customers into a single shared Oracle 11g instance on a big honkin' Windows Server 2008 server -- in order to reduce costs. I'm wondering if that's advisable. There are some advantages to having separate instances for each customer. Tell me if these are bogus, please. In my rough guess about decreasing importance: Our customers MyCorp and YourCo can be migrated separately when breaking changes are made to the schema. (With multi-client, we'd be migrating 300+ customers overnight!?!) MyCorp's data can be easily backed up and (!!!) restored, without affecting other customers. MyCorp's data is securely separated from their competitor YourCo's data, without depending on developers to get the code right and/or DBAs getting the configuration right. Performance is better because the database is smaller (5,000 vs 2,000,000 rows in ~50 tables). If MyCorp's offices are (mostly) in just one region, then the MyCorp's instance can be geographically co-located there, so network lag doesn't hurt performance. We can provide better service to global clients, for the same reason. In MyCorp wants to take their database in-house, then we can easily export their instance, to get MyCorp their data. Load-balancing is easier because instances can be placed on different servers (this is with a web farm). When a DEV or QA instance is needed, it's easier to clone the real instance and anonymize the data, because there's much less data. Because they're small enough, developers can have their own instance running locally, so they can work on code while waiting at the airport and while in-flight, without fighting VPN hassles. Q1: What are other advantages of separate instances? We are contemplating changing the database schema and merging all of our customers into one Oracle instance, running on one hefty server. Here are advantages of the multi-client instance approach, most important first (my WAG). Please snipe if these are bogus: Less work for the DBAs, since they only need to maintain one instance instead of hundreds. Less DBA work translates to cheaper, our main motive for this change. With just one instance, the DBAs can do a better job of optimizing performance. They'll have time to add appropriate indexes and review our SQL. It will be easier for developers to debug & enhance the application, because there is only one schema and one app (there might be dozens of schema versions if there are hundreds of instances, with a different version of the app for each version of the schema). This reduces costs too. The alternative is having to start every debug session with (1) What version is this customer running and (2) Let's struggle to recreate the corresponding development environment, code and database. (We need a Virtual Machine that includes the code AND database instance for each patch and release!) Licensing Oracle is cheaper because it's priced per server irrespective of heft (or something -- I don't know anything about the subject). The database becomes a viable persistent store for web session data, because there is just one instance. Some database operations are easier with one multi-client instance, like finding a participant when they're hazy about which customer they (or their spouse, maybe) works for: all the names are in one table. Reporting across customers is straightforward. Q2: What are other advantages of having multiple clients in one instance? Q3: Which approach do you think is better (why)? Instance per customer, or all customers in one instance? I'm concerned that having one multi-client instance makes migration near-impossible, and that's a deal killer... ... unless there is a compromise solution like having two multi-client instances, the old and the new. In that case case, we would design cross-instance solutions for finding participants, reporting, etc. so customers could go from one multi-client instance to the next without anything breaking. THANKS SO MUCH for your collective advice! This issue is beyond me -- but not beyond the collective you. :) Hoytster

  • Craziest JavaScript behavior I've ever seen

    - by Dan Ray
    And that's saying something. This is based on the Google Maps sample for Directions in the Maps API v3. <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> <title>Google Directions</title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var directionDisplay; var directionsService = new google.maps.DirectionsService(); var map; function initialize() { directionsDisplay = new google.maps.DirectionsRenderer(); var myOptions = { zoom:7, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); directionsDisplay.setMap(map); directionsDisplay.setPanel(document.getElementById("directionsPanel")); } function render() { var start; if(navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { start = new google.maps.LatLng(position.coords.latitude,position.coords.longitude); }, function() { handleNoGeolocation(browserSupportFlag); }); } else { // Browser doesn't support Geolocation handleNoGeolocation(); } alert("booga booga"); var end = '<?= $_REQUEST['destination'] ?>'; var request = { origin:start, destination:end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { if (status == google.maps.DirectionsStatus.OK) { directionsDisplay.setDirections(response); } }); } </script> </head> <body style="margin:0px; padding:0px;" onload="initialize()"> <div><div id="map_canvas" style="float:left;width:70%; height:100%"></div> <div id="directionsPanel" style="float:right;width:30%;height 100%"></div> <script type="text/javascript">render();</script> </body> </html> See that "alert('booga booga')" in there? With that in place, this all works fantastic. Comment that out, and var start is undefined when we hit the line to define var request. I discovered this when I removed the alert I put in there to show me the value of var start, and it quit working. If I DO ask it to alert me the value of var start, it tells me it's undefined, BUT it has a valid (and accurate!) value when we define var request a few lines later. I'm suspecting it's a timing issue--like an asynchronous something is having time to complete in the background in the moment it takes me to dismiss the alert. Any thoughts on work-arounds?

  • Google TV Gets Bad Reception. Can Media Center Pull in the Signal?

    - by andrewbrust
    The news hit Monday morning that Google has decided to delay the release of its Google TV platform, and has asked its OEMs to delay any products that embed the software.  Coming just about two weeks prior to the 2011 Consumer Electronics Show (CES), Google’s timing is about the worst imaginable.  CES is where the platform should have had its coming out party, especially given all the anticipation that has built up since its initial announcement came 7 months ago. At last year’s CES, it seemed every consumer electronics company had fashioned its own software stack for Internet-based video programming and applications/widgets on its TVs, optical disc players and set top boxes.  In one case, I even saw two platforms on a single TV set (one provided by Yahoo and the other one native to the TV set). The whole point of Google TV was to solve this problem and offer a standard, embeddable platform.  But that won’t be happening, at least not for a while.  Google seems unable to get it together, and more proprietary approaches, like Apple TV, don’t seem to be setting the world of TV-Internet convergence on fire, either. It seems to me, that when it comes to building a “TV operating system,” Windows Media Center is still the best of a bad bunch.  But it won’t stay so for much longer without some changes.  Will Redmond pick up the ball that Google has fumbled?  I’m skeptical, but hopeful.  Regardless, here are some steps that could help Microsoft make the most of Google’s faux pas: Introduce a new Media Center version that uses XBox 360, rather than Windows 7 (or 8), as the platform.  TV platforms should be appliance-like, not PC-like.  Combine that notion with the runaway sales numbers for Xbox 360 Kinect, and the mass appeal it has delivered for Xbox, and the switch form Windows makes even more sense. As I have pointed out before, Microsoft’s Xbox implementation of its Mediaroom platform (announced and demoed at last year’s CES) gets Redmond 80% of the way toward this goal.  Nothing stops Microsoft from going the other 20%, other than its own apathy, which I hope has dissipated. Reverse the decision to remove Drive Extender technology from Windows Home Server (WHS), and create deep integration between WHS and Media Center.  I have suggested this previously as well, but the recent announcement that Drive Extender would be dropped from WHS 2.0 creates the need for me to a) join the chorus of people urging Microsoft to reconsider and b) reiterate the importance of Media Center-WHS integration in the context of a Google compete scenario. Enable Windows Phone 7 (WP7) as a Media Center client.  This would tighten the integration loop already established between WP7, Xbox and Zune.  But it would also counter Echostar/DISH Network/Sling Media, strike a blow against Google/Android (and even Apple/iOS) and could be the final strike against TiVO. Bring the WP7 user interface to Media Center and Kinect-enable it.  This would further the integration discussed above and would be appropriate recognition of WP7’s Metro UI having been built on the heritage of the original Media Center itself.  And being able to run your DVR even if you can’t find the remote (or can’t see its buttons in the dark) could be a nifty gimmick. Microsoft can do this but its consumer-oriented organization, responsible for Xbox, Zune and WP7, has to take the reins here, or none of this will likely work.  There’s a significant chance that won’t happen, but I won’t let that stop me from hoping that it does and insisting that it must.  Honestly, this fight is Microsoft’s to lose.

  • Download YouTube Videos the Easy Way

    - by Trevor Bekolay
    You can’t be online all the time, and despite the majority of YouTube videos being nut-shots and Lady Gaga parodies, there is a lot of great content that you might want to download and watch offline. There are some programs and browser extensions to do this, but we’ve found that the easiest and quickest method is a bookmarklet that was originally posted on the Google Operating System blog (it’s since been removed). It will let you download standard quality and high-definition movies as MP4 files. Also, because it’s a bookmarklet, it will work on any modern web browser, and on any operating system! Installing the bookmarket is easy – just drag and drop the Get YouTube video link below to the bookmarks bar of your browser of choice. If you’ve hidden the bookmark bar, in most browsers you can right-click on the link and save it to your bookmarks. Get YouTube video   With the bookmarklet available in your browser, go to the YouTube video that you’d like to download. Click on the Get YouTube video link in your bookmarks bar, or in the bookmarks menu, wherever you saved it earlier. You will notice some new links appear below the description of the video. If you download the standard definition file, it will save as “video.mp4” by default. However, if you download the high definition file, it will save with the same name as the title of the video. There are many methods of downloading YouTube videos…but we think this is the easiest and quickest method. You don’t have to install anything or use up resources, but you can still get a link to download an MP4 with one click. Do you use a different method to download Youtube videos? Let us know about it in the comments! javascript:(function(){if(document.getElementById(’download-youtube-video’))return;var args=null,video_title=null,video_id=null,video_hash=null;var download_code=new Array();var fmt_labels={‘18′:’standard%20MP4′,’22′:’HD%20720p’,'37′:’HD%201080p’};try{args=yt.getConfig(’SWF_ARGS’);video_title=yt.getConfig(’VIDEO_TITLE’)}catch(e){}if(args){var fmt_url_map=unescape(args['fmt_url_map']);if(fmt_url_map==”)return;video_id=args['video_id'];video_hash=args['t'];video_title=video_title.replace(/[%22\'\?\\\/\:\*%3C%3E]/g,”);var fmt=new Array();var formats=fmt_url_map.split(’,');var format;for(var i=0;i%3Cformats.length;i++){var format_elems=formats[i].split(’|');fmt[format_elems[0]]=unescape(format_elems[1])}for(format in fmt_labels){if(fmt[format]!=null){download_code.push(’%3Ca%20href=\”+(fmt[format]+’&title=’+video_title)+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}elseif(format==’18′){download_code.push(’%3Ca%20href=\’http://www.youtube.com/get_video?fmt=18&video_id=’+video_id+’&t=’+video_hash+’\'%3E’+fmt_labels[format]+’%3C/a%3E’)}}}if(video_id==null||video_hash==null)return;var div_embed=document.getElementById(’watch-embed-div’);if(div_embed){var div_download=document.createElement(’div’);div_download.innerHTML=’%3Cbr%20/%3E%3Cspan%20id=\’download-youtube-video\’%3EDownload:%20′+download_code.join(’%20|%20′)+’%3C/span%3E’;div_embed.appendChild(div_download)}})() Similar Articles Productive Geek Tips Watch YouTube Videos in Cinema Style in FirefoxDownload YouTube Videos with Cheetah YouTube DownloaderStop YouTube Videos from Automatically Playing in FirefoxImprove YouTube Video Viewing in Google ChromeConvert YouTube Videos to MP3 with YouTube Downloader TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional 15 Great Illustrations by Chow Hon Lam Easily Sync Files & Folders with Friends & Family Amazon Free Kindle for PC Download Stretch popurls.com with a Stylish Script (Firefox) OldTvShows.org – Find episodes of Hitchcock, Soaps, Game Shows and more Download Microsoft Office Help tab

  • 6 Prominent Features of New GMail User Interface

    - by Gopinath
    GMail’s user interface has got a big make over today and the new user interface is available to everyone. We can switch to the new user interface by click on “Switch to the new look” link available at the bottom right of GMail (If you are on IE 6 or similar type of bad browsers, you will not see the option!). I switched to the new user interface as soon I noticed the link and played with it for sometime. In this post I want to share the prominent features of all new GMail interface. 1. All New Conversations Interface GMail’s threaded conversations is a game changing feature when it was first introduced by Google. For  a long time we have not seen much updates to the threaded conversation views. In the new GMail interface, threaded conversation sports a great new look – conversations are always visible in a horizontal fashion as opposed to stack interface of earlier version. When you open a conversation, you get a quick glance of individual thread without expanding the thread. Readability is improved a lot now.  Check image after the break 2. Sender Profile Photos In Email Threads Did you observe the above screenshot of conversations view? It has profile images of the participants in the thread. Identifying person of a thread is much more easy. 3. Advanced Search Box Search is the heart of Google’s business and it’s their flagship technology. GMail’s search interface is enhanced to let you quickly find the required e-mails. Also you can create mail filters from the search box without leaving the screen or opening up a new popup. 4. Gmail Automatically Resizing To Fit Multiple Devices There is no doubt that this is post PC era where people started using more of tablets and big screen smartphones than ever. The new user interface of GMail automatically resizes itself to fit the size of screen seamlessly. 5. HD Images For Your Themes, Sourced from iStockphoto Are you bored with minimalistic GMail interface and the few flashy themes? Here comes GMail HD themes backed by stock photographs sourced from iStockPhoto website. If you have a widescreen HD monitor then decorate your inbox with beautiful themes. 6. Resize Labels & Chat Panels Now you got a splitter between Labels & Chat panel that lets resize their height as you prefer. Also Label panel auto expands its height when you mouse over to show you hidden labels if any. Video – overview of new GMail features This article titled,6 Prominent Features of New GMail User Interface, was originally published at Tech Dreams.

  • Chrome Web Browser Messages: Some Observations

    - by ultan o'broin
    I'm always on the lookout for how different apps handle errors and what kind of messages are shown (I probably need to get out more), I use this 'research' to reflect on our own application error messages patterns and guidelines and how we might make things better for our users in future. Users are influenced by all sorts of things, but their everyday experiences of technology, and especially what they encounter on the internet, increasingly sets their expectations for the enterprise user experience too. I recently came across a couple of examples from Google's Chrome web browser that got me thinking. In the first case, we have a Chrome error about not being able to find a web page. I like how simple, straightforward messaging language is used along with an optional ability to explore things a bit further--for those users who want to. The 'more information' option shows the error encountered by the browser (or 'original' error) in technical terms, along with an error number. Contrasting the two messages about essentially the same problem reveals what's useful to users and what's not. Everyone can use the first message, but the technical version of the message has to be explicitly disclosed for any more advanced user to pursue further. More technical users might search for a resolution, using that Error 324 number, but I imagine most users who see the message will try again later or check their URL again. Seems reasonable that such an approach be adopted in the enterprise space too, right? Maybe. Generally, end users don't go searching for solutions based on those error numbers, and help desk folks generally prefer they don't do so. That's because of the more critical nature of enterprise data or the fact that end users may not have the necessary privileges to make any fixes anyway. What might be more useful here is a link to a trusted source of additional help provided by the help desk or reputable community instead. This takes me on to the second case, this time more closely related to the language used in messaging situations. Here, I first noticed by the using of the (s) approach to convey possibilities of there being one or more pages at the heart of the problem. This approach is a no-no in Oracle style terms (the plural would be used) and it can create translation issues (though it is not a show-stopper). I think Google could have gone with the plural too. However, of more interest is the use of the verb "kill", shown in the message text and as an action button label. For many writers, words like "kill" and "abort" are to be avoided as they can give offense. I am not so sure about that judgment, as really their use cannot be separated from the context. Certainly, for more technical users, they're fine and have been in use for years, so I see no reason to avoid these terms if the audience has accepted them. Most end users too, I think would find the idea of "kill" usable and may even use the term in every day speech. Others might disagree--Apple uses a concept of Force Quit, for example. Ultimately, the only way to really know how to proceed is to research these matter by asking users of differing roles and expertise to perform some tasks, encounter these messages and then make recommendations based on those findings for our designs. Something to do in 2011!

  • Why would Copying a Large Image to the Clipboard Freeze a Computer?

    - by Akemi Iwaya
    Sometimes, something really odd happens when using our computers that makes no sense at all…such as copying a simple image to the clipboard and the computer freezing up because of it. An image is an image, right? Today’s SuperUser post has the answer to a puzzled reader’s dilemna. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Original image courtesy of Wikimedia. The Question SuperUser reader Joban Dhillon wants to know why copying an image to the clipboard on his computer freezes it up: I was messing around with some height map images and found this one: (http://upload.wikimedia.org/wikipedia/commons/1/15/Srtm_ramp2.world.21600×10800.jpg) The image is 21,600*10,800 pixels in size. When I right click and select “Copy Image” in my browser (I am using Google Chrome), it slows down my computer until it freezes. After that I must restart. I am curious about why this happens. I presume it is the size of the image, although it is only about 6 MB when saved to my computer. I am also using Windows 8.1 Why would a simple image freeze Joban’s computer up after copying it to the clipboard? The Answer SuperUser contributor Mokubai has the answer for us: “Copy Image” is copying the raw image data, rather than the image file itself, to your clipboard. The raw image data will be 21,600 x 10,800 x 3 (24 bit image) = 699,840,000 bytes of data. That is approximately 700 MB of data your browser is trying to copy to the clipboard. JPEG compresses the raw data using a lossy algorithm and can get pretty good compression. Hence the compressed file is only 6 MB. The reason it makes your computer slow is that it is probably filling your memory up with at least the 700 MB of image data that your browser is using to show you the image, another 700 MB (along with whatever overhead the clipboard incurs) to store it on the clipboard, and a not insignificant amount of processing power to convert the image into a format that can be stored on the clipboard. Chances are that if you have less than 4 GB of physical RAM, then those copies of the image data are forcing your computer to page memory out to the swap file in an attempt to fulfil both memory demands at the same time. This will cause programs and disk access to be sluggish as they use the disk and try to use the data that may have just been paged out. In short: Do not use the clipboard for huge images unless you have a lot of memory and a bit of time to spare. Like pretty graphs? This is what happens when I load that image in Google Chrome, then copy it to the clipboard on my machine with 12 GB of RAM: It starts off at the lower point using 2.8 GB of RAM, loading the image punches it up to 3.6 GB (approximately the 700 MB), then copying it to the clipboard spikes way up there at 6.3 GB of RAM before settling back down at the 4.5-ish you would expect to see for a program and two copies of a rather large image. That is a whopping 3.7 GB of image data being worked on at the peak, which is probably the initial image, a reserved quantity for the clipboard, and perhaps a couple of conversion buffers. That is enough to bring any machine with less than 8 GB of RAM to its knees. Strangely, doing the same thing in Firefox just copies the image file rather than the image data (without the scary memory surge). Have something to add to the explanation? Sound off in the comments.

  • Google Chrome: XMLHttpRequest.send() not working while doing POST.

    - by Dave Van den Eynde
    I'm working on an application that allows the user to send a file using a form (a POST request), and that executes a series of GET requests while that file is being uploaded to gather information about the state of the upload. It works fine in IE and Firefox, but not so much in Chrome and Safari. The problem is that even though send() is called on the XMLHttpRequest object, nothing is being requested as can be seen in Fiddler. To be more specific, an event handler is placed on the "submit" event of the form, that places a timeout function call on the window: window.setTimeout(startPolling, 10); and in this function "startPolling" sequence is started that keeps firing GET requests to receive status updates from a web service that returns text/json that can be used to update the UI. Is this a limitation (perhaps security-wise?) on WebKit based browsers? Is this a Chrome bug? (I'm seeing the same behaviour in Safari though).

  • jQuery load Google Visualization API with AJAX

    - by Curro
    Hello. There is an issue that I cannot solve, I've been looking a lot in the internet but found nothing. I have this JavaScript that is used to do an Ajax request by PHP. When the request is done, it calls a function that uses the Google Visualization API to draw an annotatedtimeline to present the data. The script works great without AJAX, if I do everything inline it works great, but when I try to do it with AJAX it doesn't work!!! The error that I get is in the declaration of the "data" DataTable, in the Google Chrome Developer Tools I get a Uncaught TypeError: Cannot read property 'DataTable' of undefined. When the script gets to the error, everything on the page is cleared, it just shows a blank page. So I don't know how to make it work. Please help Thanks in advance $(document).ready(function(){ // Get TIER1Tickets $("#divTendency").addClass("loading"); $.ajax({ type: "POST", url: "getTIER1Tickets.php", data: "", success: function(html){ // Succesful, load visualization API and send data google.load('visualization', '1', {'packages': ['annotatedtimeline']}); google.setOnLoadCallback(drawData(html)); } }); }); function drawData(response){ $("#divTendency").removeClass("loading"); // Data comes from PHP like: <CSV ticket count for each day>*<CSV dates for ticket counts>*<total number of days counted> // So it has to be split first by * then by , var dataArray = response.split("*"); var dataTickets = dataArray[0]; var dataDates = dataArray[1]; var dataCount = dataArray[2]; // The comma separation now splits the ticket counts and the dates var dataTicketArray = dataTickets.split(","); var dataDatesArray = dataDates.split(","); // Visualization data var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'Tickets'); data.addRows(dataCount); var dateSplit = new Array(); for(var i = 0 ; i < dataCount ; i++){ // Separating the data because must be entered as "new Date(YYYY,M,D)" dateSplit = dataDatesArray[i].split("-"); data.setValue(i, 0, new Date(dateSplit[2],dateSplit[1],dateSplit[0])); data.setValue(i, 1, parseInt(dataTicketArray[i])); } var annotatedtimeline = new google.visualization.AnnotatedTimeLine(document.getElementById('divTendency')); annotatedtimeline.draw(data, {displayAnnotations: true}); }
