  • Convert Chrome Bookmark Toolbar Folders to Icons

    - by Asian Angel
    So you have your regular bookmarks reduced to icons but what about the folders? With our little hack and a few minutes of your time you can turn those folders into icons too. Condensing the Folders Reducing bookmark folders to icons is a little more tricky than regular bookmarks but not hard to do. Right click on the folder and select “Rename…”. The folder’s name should already be highlighted/selected as shown here. Delete the text…notice that the “OK Button” has become unusable for the moment. Now what you will need to do is: Hold down the “Alt Key” Type in “0160” (without the quotes) using the numbers keypad on the right side of your keyboard Release the “Alt Key” after you have finished typing in the number above Once you have released the “Alt Key” you will notice two things…the “cursor” has moved further into the text area and you can now click on the “OK Button” again. There is our folder after editing. And it works just as well as before but without taking up so much room. Here is how our “iconized” folder looks next to our bookmarks. Perfect! What if you want to reduce multiple folders to icons? Perform the same exact steps shown above for each folder and pack your “Bookmarks Toolbar” full of folder goodness! As seen here the folders will have a little more space between them in comparison with singular bookmarks due to the “blank name” for each folder. For those who may be curious this is what your bookmarks will look like in the “Bookmark Manager Page”. Note: If you export your bookmarks all bookmarks contained in multiple blank name folders will be combined into a single folder. Conclusion With just a little bit of work you can pack a lot of goodness into your “Bookmarks Toolbar”. No more wasted space… Similar Articles Productive Geek Tips Condense the Bookmarks in the Firefox Bookmarks ToolbarAccess Your Bookmarks with a Toolbar Button in Google ChromeAdd the Bookmarks Menu to Your Bookmarks Toolbar with Bookmarks UI ConsolidatorAdd a Vertical Bookmarks Toolbar to FirefoxReduce Your Bookmarks Toolbar to a Toolbar Button 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 DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 OutlookStatView Scans and Displays General Usage Statistics How to Add Exceptions to the Windows Firewall Office 2010 reviewed in depth by Ed Bott FoxClocks adds World Times in your Statusbar (Firefox) Have Fun Editing Photo Editing with Citrify Outlook Connector Upgrade Error

  • Master Data Management Implementation Styles

    - by david.butler(at)oracle.com
    In any Master Data Management solution deployment, one of the key decisions to be made is the choice of the MDM architecture. Gartner and other analysts describe some different Hub deployment styles, which must be supported by a best of breed MDM solution in order to guarantee the success of the deployment project.   Registry Style: In a Registry Style MDM Hub, the various source systems publish their data and a subscribing Hub stores only the source system IDs, the Foreign Keys (record IDs on source systems) and the key data values needed for matching. The Hub runs the cleansing and matching algorithms and assigns unique global identifiers to the matched records, but does not send any data back to the source systems. The Registry Style MDM Hub uses data federation capabilities to build the "virtual" golden view of the master entity from the connected systems.   Consolidation Style: The Consolidation Style MDM Hub has a physically instantiated, "golden" record stored in the central Hub. The authoring of the data remains distributed across the spoke systems and the master data can be updated based on events, but is not guaranteed to be up to date. The master data in this case is usually not used for transactions, but rather supports reporting; however, it can also be used for reference operationally.   Coexistence Style: The Coexistence Style MDM Hub involves master data that's authored and stored in numerous spoke systems, but includes a physically instantiated golden record in the central Hub and harmonized master data across the application portfolio. The golden record is constructed in the same manner as in the consolidation style, and, in the operational world, Consolidation Style MDM Hubs often evolve into the Coexistence Style. The key difference is that in this architectural style the master data stored in the central MDM system is selectively published out to the subscribing spoke systems.   Transaction Style: In this architecture, the Hub stores, enhances and maintains all the relevant (master) data attributes. It becomes the authoritative source of truth and publishes this valuable information back to the respective source systems. The Hub publishes and writes back the various data elements to the source systems after the linking, cleansing, matching and enriching algorithms have done their work. Upstream, transactional applications can read master data from the MDM Hub, and, potentially, all spoke systems subscribe to updates published from the central system in a form of harmonization. The Hub needs to support merging of master records. Security and visibility policies at the data attribute level need to be supported by the Transaction Style hub, as well.   Adaptive Transaction Style: This is similar to the Transaction Style, but additionally provides the capability to respond to diverse information and process requests across the enterprise. This style emerged most recently to address the limitations of the above approaches. With the Adaptive Transaction Style, the Hub is built as a platform for consolidating data from disparate third party and internal sources and for serving unified master entity views to operational applications, analytical systems or both. This approach delivers a real-time Hub that has a reliable, persistent foundation of master reference and relationship data, along with all the history and lineage of data changes needed for audit and compliance tracking. On top of this persistent master data foundation, the Hub can dynamically aggregate transaction data on demand from different source systems to deliver the unified golden view to downstream systems. Data can also be accessed through batch interfaces, published to a message bus or served through a real-time services layer. New data sources can be readily added in this approach by extending the data model and by configuring the new source mappings and the survivorship rules, meaning that all legacy data hubs can be leveraged to contribute their records/rules into the new transaction hub. Finally, through rich user interfaces for data stewardship, it allows exception handling by business analysts to keep it current with business rules/practices while maintaining the reliability of best-of-breed master records.   Confederation Style: In this architectural style, several Hubs are maintained at departmental and/or agency and/or territorial level, and each of them are connected to the other Hubs either directly or via a central Super-Hub. Each Domain level Hub can be implemented using any of the previously described styles, but normally the Central Super-Hub is a Registry Style one. This is particularly important for Public Sector organizations, where most of the time it is practically or legally impossible to store in a single central hub all the relevant constituent information from all departments.   Oracle MDM Solutions can be deployed according to any of the above MDM architectural styles, and have been specifically designed to fully support the Transaction and Adaptive Transaction styles. Oracle MDM Solutions provide strong data federation and integration capabilities which are key to enabling the use of the Confederated Hub as a possible architectural style approach. Don't lock yourself into a solution that cannot evolve with your needs. With Oracle's support for any type of deployment architecture, its ability to leverage the outstanding capabilities of the Oracle technology stack, and its open interfaces for non-Oracle technology stacks, Oracle MDM Solutions provide a low TCO and a quick ROI by enabling a phased implementation strategy.

  • How do I clear xmodmap settings?

    - by Wayne Werner
    Exactly what the title asks. How do I clear xmodmap settings? I have an IBM model M, and somehow xkeycaps got it into its head that my "End" key was not any key at all. xev reports keypresses when I use it, so I know the event is being generated by the keyboard. Also, xkeycaps thinks that my arrow keys are all wonky, and apparently the scrollbar is broken so it only scrolls down - so I can't scroll up to find an IBM keyboard that just maybe is close to my map so I can fix my keys. So I'm trying to reset my keyboard to the default settings, but the xmodmap manpage is woefully devoid of "reset all" or "clear all" or anything of that nature (that I was able to find). Help would be greatly appreciated!

  • How to know which fields of a record are updated in saving the edit? [closed]

    - by Luiz Maffort
    I'm recording in a log table all that is changed in a given table, so this need to know when for example the User to change the status from active to inactive. With this information I will write in my log table information of which record was changed, by whom and what was the value of old and new. If I instantiate an object before: db.Entry(chamados).State = EntityState.Modified; I can even compare, but this error appears at runtime. *An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. * Podem me ajudar por favor?

  • How to send credentials to linkedIn website and get oauth_verifier without signing in again [closed]

    - by akash kumar
    I am facing a problem sending credentials to another website so that I can login the user (automatically, not clicked on sign in here) and get an oauth_verifier value. I want to send the email address and the password through a form (submit button) from my website (e.g. a Liferay portal) to another website (e.g. LinkedIn), so that it automatically returns an oauth_verifier to my website. That means I don't want the user of my website to submit his email and password to LinkedIn again. My goal is to take the email and password of the user in my website and show the user his LinkedIn connection, message, job posting (again, in my website, not LinkedIn). I dont want the user redirected to the LinkedIn website to sign in there and then come back to my website. I have taken a consumer key and a secret key from LinkedIn for my web aplication. I am using the LinkedIn API and getting oauth_verifier for access token but in order to login, I have to take user to LinkedIn to sign in, while I want it to happen in the backend.

  • How do I fix postfix TLS?

    - by Savanni D'Gerinel
    STARTTLS was working with my system earlier today. Without me altering the system in any way, it spontaneously broke. I've now been trying to fix it for a couple of hours, to no success. When I connect to the server, this is what I get: savanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.sasavanni@Orolo:~$ telnet apps.savannidgerinel.com 25 Trying 129.121.182.135... Connected to apps.savannidgerinel.com.

Okay, obviously STARTTLS isn't present in this list. So I've been digging through my configuration files and working through the tutorials again, and that has done me no good at all. Here's my tls-related configuration: smtp_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtp_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtp_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_tls_CAfile = /etc/ssl/certs/savannidgerinel_com_CA.pem smtpd_tls_cert_file = /etc/ssl/certs/apps.savannidgerinel.com.pem smtpd_tls_key_file = /etc/ssl/private/apps.savannidgerinel.com.key.pem smtpd_tls_loglevel = 3 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache tls_random_source = dev:/dev/urandom All of the certificate files are present, the server private key is present, the server CA is present, and the smtpd_scache.db and smtp_scache.db files are both present. All are accessible to the postfix user. Speaking of which, here are the processes running: savanni@apps:/var/lib/postfix$ ps aux | grep postfix root 3525 0.0 0.1 25112 1680 ?

  • My Reference for Amy Lewis

    - by Denise McInerney
    The 2013 election campaign for the PASS Board of Directors is underway. There are seven qualified candidates running this year. They all offer a wealth of experience volunteering for PASS and the SQL Server community. One of these candidates, Amy Lewis, asked me to write a reference for her to include on her candidate application. I have a lot of experience working with Amy and was pleased to provide this reference: I enthusiastically support Amy Lewis as a candidate for the PASS Board of Directors. I have known and worked with Amy in various PASS' volunteer capacities for years, starting when we were both leaders of SIGs (the precursors to the Virtual Chapters.) In that time I have seen Amy grow as a leader, taking on increasing responsibility and developing her leadership skills in the process. From the Program Committee to the BI Virtual Chapter to her local user group's SQL Saturday Amy has demonstrated a capacity to organize and lead volunteers. A successful leader delivers results, and does so in a way that encourages and empowers the people she is working with; Amy embodies this leadership style. As Director for Virtual Chapters I have most recently worked with Amy in her capacity of DW/BI VC Leader. This VC is one of our largest and most active, and Amy's leadership is a key contribution to that success. I was pleased to see that Amy was also thinking about succession and prepared other volunteers to take over the chapter leadership. Amy has shown an understanding of PASS' strategic goals and has focused her volunteer efforts to help us reach those goals. For the past couple of years we have been trying to expand PASS reach and relevance to SQL communities around the world. The VCs are a key vehicle for this expansion. Amy embraced this idea and organized the VC to engage volunteers in Europe & Australia and provide content that could reach SQL professionals in those regions. A second key strategy for PASS is expanding into the data analytics space. Again Amy rose to the occasion helping to shape the program for our first Business Analytics Conference and leveraging the BI VC to promote the event. By all measures I think Amy is prepared to serve on the Board and contribute in a positive way.

  • Monogame - Input secuence game (Scripting?)

    - by user2662567
    I'm starting to program my very first game, it's a clone of DDR/Stepmania done for research purposes and learning. I (at this early stage) get most of the UI/Music/input work that should be done, but what i still can't grasp is scripting, i've read about Lua and that you shouldn't use it with XNA/Monogame as C# is capable enough, but i cannot get the utility of it. Assuming the needs of my game, ¿What would be the ideal way to implement the input secuences it needs?, i thought of XML/Json, let's say Stage 1 <game> <level id="1"> <step id="1" key="up" time="00:00:01"/> <step id="2" key="left" time="00:00:02"/> </level> </game> Is that a correct implementation? or are there better ways with more benefits?

  • Connecting a LAN to an OpenVPN server via a windows 7 client gateway

    - by user705142
    I've got OpenVPN set up between my windows 7 client and linux server. The goal is that I'll get secure access to a webapp running on the server from any computer on the client LAN. I'm using ccd to assign static ip addresses to each client connection, with key authentication. It's working on my client machine (10.83.41.9), and when you go to the gateway IP address (10.83.41.1), it loads up the webapp. Now I really need the other computers on the client LAN to be able to connect to the webapp as well, via the windows machine.

  • Some non-generic collections

    - by Simon Cooper
    Although the collections classes introduced in .NET 2, 3.5 and 4 cover most scenarios, there are still some .NET 1 collections that don't have generic counterparts. In this post, I'll be examining what they do, why you might use them, and some things you'll need to bear in mind when doing so. BitArray System.Collections.BitArray is conceptually the same as a List<bool>, but whereas List<bool> stores each boolean in a single byte (as that's what the backing bool[] does), BitArray uses a single bit to store each value, and uses various bitmasks to access each bit individually. This means that BitArray is eight times smaller than a List<bool>. Furthermore, BitArray has some useful functions for bitmasks, like And, Xor and Not, and it's not limited to 32 or 64 bits; a BitArray can hold as many bits as you need. However, it's not all roses and kittens. There are some fundamental limitations you have to bear in mind when using BitArray: It's a non-generic collection. The enumerator returns object (a boxed boolean), rather than an unboxed bool. This means that if you do this: foreach (bool b in bitArray) { ... } Every single boolean value will be boxed, then unboxed. And if you do this: foreach (var b in bitArray) { ... } you'll have to manually unbox b on every iteration, as it'll come out of the enumerator an object. Instead, you should manually iterate over the collection using a for loop: for (int i=0; i<bitArray.Length; i++) { bool b = bitArray[i]; ... } Following on from that, if you want to use BitArray in the context of an IEnumerable<bool>, ICollection<bool> or IList<bool>, you'll need to write a wrapper class, or use the Enumerable.Cast<bool> extension method (although Cast would box and unbox every value you get out of it). There is no Add or Remove method. You specify the number of bits you need in the constructor, and that's what you get. You can change the length yourself using the Length property setter though. It doesn't implement IList. Although not really important if you're writing a generic wrapper around it, it is something to bear in mind if you're using it with pre-generic code. However, if you use BitArray carefully, it can provide significant gains over a List<bool> for functionality and efficiency of space. OrderedDictionary System.Collections.Specialized.OrderedDictionary does exactly what you would expect - it's an IDictionary that maintains items in the order they are added. It does this by storing key/value pairs in a Hashtable (to get O(1) key lookup) and an ArrayList (to maintain the order). You can access values by key or index, and insert or remove items at a particular index. The enumerator returns items in index order. However, the Keys and Values properties return ICollection, not IList, as you might expect; CopyTo doesn't maintain the same ordering, as it copies from the backing Hashtable, not ArrayList; and any operations that insert or remove items from the middle of the collection are O(n), just like a normal list. In short; don't use this class. If you need some sort of ordered dictionary, it would be better to write your own generic dictionary combining a Dictionary<TKey, TValue> and List<KeyValuePair<TKey, TValue>> or List<TKey> for your specific situation. ListDictionary and HybridDictionary To look at why you might want to use ListDictionary or HybridDictionary, we need to examine the performance of these dictionaries compared to Hashtable and Dictionary<object, object>. For this test, I added n items to each collection, then randomly accessed n/2 items: So, what's going on here? Well, ListDictionary is implemented as a linked list of key/value pairs; all operations on the dictionary require an O(n) search through the list. However, for small n, the constant factor that big-o notation doesn't measure is much lower than the hashing overhead of Hashtable or Dictionary. HybridDictionary combines a Hashtable and ListDictionary; for small n, it uses a backing ListDictionary, but switches to a Hashtable when it gets to 9 items (you can see the point it switches from a ListDictionary to Hashtable in the graph). Apart from that, it's got very similar performance to Hashtable. So why would you want to use either of these? In short, you wouldn't. Any gain in performance by using ListDictionary over Dictionary<TKey, TValue> would be offset by the generic dictionary not having to cast or box the items you store, something the graphs above don't measure. Only if the performance of the dictionary is vital, the dictionary will hold less than 30 items, and you don't need type safety, would you use ListDictionary over the generic Dictionary. And even then, there's probably more useful performance gains you can make elsewhere.

  • cannot use sudo on ubuntu server passwordless authentication?

    - by Lucas Crijns
    Hello I'm new at the forum and I want to introduce myself: I'm Lucas Crijns and I'm a very happy user of ubuntu server. I was reading about passwordless authentication with ssh. So I made a key and published it to ubuntu server, it worked well and I could login with my private key. But then I locked the account to prevent hacking from my password. After I ran "passwd -l lucas", I was not longer able by my next login to use sudo. Because it was asking for a password and I locked it. I was thinking that sudo would also be without a password. My question is now: is it possible to use sudo? And how can I enable it without a valid password for sudo? Thank you for your help!

  • Keyboard shortcuts get randomly reset

    - by Andrei
    I'm facing a rather weird issue in the past few days after doing a clean install of Ubuntu Oneiric (w/ gnome-shell) on my recently-bought Asus U36SD. I set up my keyboard shortcuts using System Settings Keyboard Shortcuts, and some of them get randomly reset. Most of my shortcuts include the win key (otherwise listed in the keyboard shortcuts as Mod4), but those containing only Mod4 + get reset every two-three reboots. For instance, Mod4 + T (for terminal), gets reset to the standard Ctrl + Alt + T, while Shift + Mod4 + W (for browser) doesn't (I've set up the latter with the Shift key, because it seems that Mod4 + W didn't get intercepted at all. Something similar goes for Mod4 + E for gedit, which only worked once or twice). I have no idea if this is a Ubuntu specific issue, or it's related to gnome-shell or even with my current hardware. Has this happened to any of you? If so, did you manage to fix it?

  • Drawing shapes dynamically on an image through web browser

    - by Tom Beech
    We have a scenario where we create floor plans of locations when we visit. The floor plan is finally shown on the web. It's come to the point now where we want to show floor plans but have a key with various items on them, when an item on the key is clicked, the image should highlight all the areas of the floorplan that have that specific item. I guess we're looking for some sort of open standard javascript lib to deal with SVG (has to work pre IE9 so pure SVG wont cut it) and the floor plans have to be able to be created through a .net application to be deployed on the web. I'd rather stay away from flash if at all possible to be honest. Below are a few conceptual images of what we're trying to achieve.

  • Dead keys in emacs with ibus

    - by Virgile
    I've just upgraded to 13.10 and noticed that dead keys are not working anymore in emacs (a keystroke to ' leads emacs to display <dead-acute> is undefined instead of waiting to the next key. In addition, use of the compose key leads to <Multi_key> is undefined and it is impossible to use keybindings such as <M-^>. Other applications work fine as far as I can tell. A brief search on the internet suggested to (require 'isotransl) to .emacs. This solves the first issue, but not the other ones. Another possible workaround seen on the web is to launch emacs with an empty XMODIFIERS variable, as XMODIFIERS='' emacs, instead of XMODIFIERS= @im=ibus which seems to be the default in 13.10. Then everything works fine, but it looks like a kludge. Is there a way to make emacs work with ibus on this subject?

  • Sending keyboard commands to Ubuntu through Python. Remote for my Blackberry

    - by Rudi Strydom
    I am trying to build a remote control application to control media on my Ubuntu. Does anyone know a way in order to accomplish this. The media keys in particular. Thank you. EDIT 1: I have tried using XTE, but is seems python in truncating the input or there is a limit or something which means that you can't do Ctrl + Key key presses, which wont suit my needs. I also tried uinput, but alas you need to run it as root, which also will not quite my needs. Now I am looking at EVDEV which seems promicing, that is if I can get it working.

  • How can I get six Xbox controllers to provide input to an HTML5 game?

    - by Daniel X Moore
    I'm creating a six player HTML 5 game designed to be played locally (Red Ice). I've previous set up handling 7 Wiimotes using something along the lines of Joy2Key to map each input for each player to a separate keyboard key, but Wiimotes are pretty hard on the hands for these types of games and not very ergonomic so I thought I'd try and get Xbox controller support. I don't believe that any simple key mapping solution will work due to the nature of the directional stick. My inclination is that this will require a browser plugin and if so I'd prefer to write the plugin for Google Chrome. How do I create a Chrome browser plugin to handle multiple Xbox controllers or is there some other way? Please do not answer this question saying it can't be done, because it absolutely can. EDIT: I don't believe any keymapping/mouse simulating solution will work unless it can reliably distinguish six axis of inputs, one per player.
