  • Online image resizer

    - by Happy
    Searching for some script or service for online image resizing. I should have the ability to throw my imagelink, like http://site.com/bigimage.jpg, and it must give me this image after resizing like http://site-were-image-resized.com/sdf4234f21f.png. It would be amazing, if I can give some values, like height and width. If I upload script on my own site, it should have the ability to resize external images from some domains. Tryed to use http://www.darrenhoyt.com/demo/timthumb/, but it doesn't work with external images.

  • This Week in Geek History: Gmail Goes Public, Deep Blue Wins at Chess, and the Birth of Thomas Edison

    - by Jason Fitzpatrick
    Every week we bring you a snapshot of the week in Geek History. This week we’re taking a peek at the public release of Gmail, the first time a computer won against a chess champion, and the birth of prolific inventor Thomas Edison. Gmail Goes Public It’s hard to believe that Gmail has only been around for seven years and that for the first three years of its life it was invite only. In 2007 Gmail dropped the invite only requirement (although they would hold onto the “beta” tag for another two years) and opened its doors for anyone to grab a username @gmail. For what seemed like an entire epoch in internet history Gmail had the slickest web-based email around with constant innovations and features rolling out from Gmail Labs. Only in the last year or so have major overhauls at competitors like Hotmail and Yahoo! Mail brought other services up to speed. Can’t stand reading a Week in Geek History entry without a random fact? Here you go: gmail.com was originally owned by the Garfield franchise and ran a service that delivered Garfield comics to your email inbox. No, we’re not kidding. Deep Blue Proves Itself a Chess Master Deep Blue was a super computer constructed by IBM with the sole purpose of winning chess matches. In 2011 with the all seeing eye of Google and the amazing computational abilities of engines like Wolfram Alpha we simply take powerful computers immersed in our daily lives for granted. The 1996 match against reigning world chest champion Garry Kasparov where in Deep Blue held its own, but ultimately lost, in a  4-2 match shook a lot of people up. What did it mean if something that was considered such an elegant and quintessentially human endeavor such as chess was so easy for a machine? A series of upgrades helped Deep Blue outright win a match against Kasparov in 1997 (seen in the photo above). After the win Deep Blue was retired and disassembled. Parts of Deep Blue are housed in the National Museum of History and the Computer History Museum. Birth of Thomas Edison Thomas Alva Edison was one of the most prolific inventors in history and holds an astounding 1,093 US Patents. He is responsible for outright inventing or greatly refining major innovations in the history of world culture including the phonograph, the movie camera, the carbon microphone used in nearly every telephone well into the 1980s, batteries for electric cars (a notion we’d take over a century to take seriously), voting machines, and of course his enormous contribution to electric distribution systems. Despite the role of scientist and inventor being largely unglamorous, Thomas Edison and his tumultuous relationship with fellow inventor Nikola Tesla have been fodder for everything from books, to comics, to movies, and video games. Other Notable Moments from This Week in Geek History Although we only shine the spotlight on three interesting facts a week in our Geek History column, that doesn’t mean we don’t have space to highlight a few more in passing. This week in Geek History: 1971 – Apollo 14 returns to Earth after third Lunar mission. 1974 – Birth of Robot Chicken creator Seth Green. 1986 – Death of Dune creator Frank Herbert. Goodnight Dune. 1997 – Simpsons becomes longest running animated show on television. Have an interesting bit of geek trivia to share?

  • Why Haven’t NFC Payments Taken Off?

    - by David Dorf
    With the EMV 2015 milestone approaching rapidly, there’s been renewed interest in smartcards, those credit cards with an embedded computer chip.  Back in 1996 I was working for a vendor helping Visa introduce a stored-value smartcard to the US.  Visa Cash was debuted at the 1996 Olympics in Atlanta, and I firmly believed it was the beginning of a cashless society.  (I later worked on MasterCard’s system called Mondex, from the UK, which debuted the following year in Manhattan). But since you don’t have a Visa Cash card in your wallet, it’s obvious the project never took off.  It was convenient for consumers, faster for merchants, and more cost-effective for banks, so why did it fail?  All emerging payment systems suffer from the chicken-and-egg dilemma.  Consumers won’t carry the cards if few merchants accept them, and merchants won’t install the terminals if few consumers have cards. Today’s emerging payment providers are in a similar pickle.  There has to be enough value for all three constituents – consumers, merchants, banks – to change the status quo.  And it’s not enough to exceed the value, it’s got to be a leap in value, because people generally resist change.  ATMs and transit cards are great examples of this, and airline kiosks and self-checkout systems are to a lesser extent. Although Google Wallet and ISIS, the two leading NFC payment platforms in the US, have shown strong commitment, there’s been very little traction.  Yes, I can load my credit card number into my phone then tap to pay, but what was the incremental value over swiping my old card?  For it to be a leap in value, it has to offer more than just payment, which I can do very easily today.  The other two ingredients are thought to be loyalty programs and digital coupons, but neither Google nor ISIS really did them well. Of course a large portion of the mobile phone market doesn’t even support NFC thanks to Apple, and since it’s not in their best interest that situation is unlikely to change.  Another issue is getting access to the “secure element,” the chip inside the phone where accounts numbers can be held securely.  Telco providers and handset manufacturers own that area, and they’re not willing to share with banks.  (Host Card Emulation, which has been endorsed by MasterCard and Visa, might be a solution.) Square recently gave up on its wallet, and MCX (the group of retailers trying to create a mobile payment platform) is very slow out of the gate.  That leaves PayPal and a slew of smaller companies trying to introduce easier ways to pay. But is it really so cumbersome to carry and swipe (soon to insert) a credit card?  Aren’t there more important problems to solve in the retail customer experience?  Maybe Apple will come up with some novel way to use iBeacons and fingerprint identification to make payments, but for now I think we need to focus on upgrading to Chip-and-PIN and tightening security.  In the meantime, NFC payments will continue to struggle.

  • Comparing Isis, Google, and Paypal

    - by David Dorf
    Back in 2010 I was sure NFC would make great strides, but here we are two years later and NFC doesn't seem to be sticking. The obvious reason being the chicken-and-egg problem.  Retailers don't want to install the terminals until the phones support NFC, and vice-versa. So consumers continue to sit on the sidelines waiting for either side to blink and make the necessary investment.  In the meantime, EMV is looking for a way to sneak into the US with the help of the card brands. There are currently three major solutions that are battling in the marketplace.  All three know that replacing mag-stripe alone is not sufficient to move consumers.  Long-term it's the offers and loyalty programs combined with tendering that make NFC attractive. NFC solutions cross lots of barriers, so a strong partner system is required.  The solutions need to include the carriers, card brands, banks, handset manufacturers, POS terminals, and most of all lots of merchants.  Lots of coordination is necessary to make the solution seamless to the consumer. Google Wallet Google's problem has always been that only the Nexus phone has an NFC chip that supports their wallet.  There are a couple of additional phones out there now, but adoption is still slow.  They acquired Zavers a while back to incorporate digital coupons, but the the bulk of their users continue to be non-NFC.  They have taken an open approach by not specifying particular payment brands.  Google is piloting in San Francisco and New York, supporting both MasterCard PayPass and stored value. I suppose the other card brands may eventually follow.  There's no cost for consumers or merchants -- Google will make money via targeted ads. Isis Not long after Google announced its wallet, AT&T, Verizon, and T-Mobile announced a joint venture called Isis.  They are in the unique position of owning the SIM in the phones they issue.  At first it seemed Isis was a vehicle for the carriers to compete with the existing card brands, but Isis later switched to a generic wallet that supports the major card brands.  Isis reportedly charges issuers a $5 fee per customer per year.  Isis will pilot this summer in Salt Lake City and Austin. PayPal PayPal, the clear winner in the online payment space beyond traditional credit cards, is trying to move into physical stores.  After negotiations with Google to provide a wallet broke off, PayPal decided to avoid NFC altogether, at least for now, and focus on payments without any physical card or phone.  By avoiding NFC, consumers don't need an NFC-enabled phone and merchants don't need a new reader.  Consumers must enter their phone number and PIN in the merchant's existing device, or they can enter their PIN in the PayPal inStore app running on their phone, then show the merchant a unique barcode which authorizes payment. Paypal is free for consumers and charges a fee for merchants.  Its not clear, at least to me, how PayPal handles fraudulent transactions and whether the consumer is protected. The wildcard is, of course, Apple.  Their mobile technologies set the standard, so incorporating NFC chips would certainly accelerate adoption of many payment solutions.  Their announcement today of the iOS Passbook is a step in the right direction, but stops short of handling payments. For those retailers that have invested in modern terminals, it seems the best strategy is to support all the emerging solutions and let the consumers choose the winner.

  • Good DBAs Do Baselines

    - by Louis Davidson
    One morning, you wake up and feel funny. You can’t quite put your finger on it, but something isn’t quite right. What now? Unless you happen to be a hypochondriac, you likely drag yourself out of bed, get on with the day and gather more “evidence”. You check your symptoms over the next few days; do you feel the same, better, worse? If better, then great, it was some temporal issue, perhaps caused by an allergic reaction to some suspiciously spicy chicken. If the same or worse then you go to the doctor for some health advice, but armed with some data to share, and having ruled out certain possible causes that are fixed with a bit of rest and perhaps an antacid. Whether you realize it or not, in comparing how you feel one day to the next, you have taken baseline measurements. In much the same way, a DBA uses baselines to gauge the gauge health of their database servers. Of course, while SQL Server is very willing to share data regarding its health and activities, it has almost no idea of the difference between good and bad. Over time, experienced DBAs develop “mental” baselines with which they can gauge the health of their servers almost as easily as their own body. They accumulate knowledge of the daily, natural state of each part of their database system, and so know instinctively when one of their databases “feels funny”. Equally, they know when an “issue” is just a passing tremor. They see their SQL Server with all of its four CPU cores running close 100% and don’t panic anymore. Why? It’s 5PM and every day the same thing occurs when the end-of-day reports, which are very CPU intensive, are running. Equally, they know when they need to respond in earnest when it is the first time they have heard about an issue, even if it has been happening every day. Nevertheless, no DBA can retain mental baselines for every characteristic of their systems, so we need to collect physical baselines too. In my experience, surprisingly few DBAs do this very well. Part of the problem is that SQL Server provides a lot of instrumentation. If you look, you will find an almost overwhelming amount of data regarding user activity on your SQL Server instances, and use and abuse of the available CPU, I/O and memory. It seems like a huge task even to work out which data you need to collect, let alone start collecting it on a regular basis, managing its storage over time, and performing detailed comparative analysis. However, without baselines, though, it is very difficult to pinpoint what ails a server, just by looking at a single snapshot of the data, or to spot retrospectively what caused the problem by examining aggregated data for the server, collected over many months. It isn’t as hard as you think to get started. You’ve probably already established some troubleshooting queries of the type SELECT Value FROM SomeSystemTableOrView. Capturing a set of baseline values for such a query can be as easy as changing it as follows: INSERT into BaseLine.SomeSystemTable (value, captureTime) SELECT Value, SYSDATETIME() FROM SomeSystemTableOrView; Of course, there are monitoring tools that will collect and manage this baseline data for you, automatically, and allow you to perform comparison of metrics over different periods. However, to get yourself started and to prove to yourself (or perhaps the person who writes the checks for tools) the value of baselines, stick something similar to the above query into an agent job, running every hour or so, and you are on your way with no excuses! Then, the next time you investigate a slow server, and see x open transactions, y users logged in, and z rows added per hour in the Orders table, compare to your baselines and see immediately what, if anything, has changed!

  • Solving Diophantine Equations Using Python

    - by HARSHITH
    In mathematics, a Diophantine equation (named for Diophantus of Alexandria, a third century Greek mathematician) is a polynomial equation where the variables can only take on integer values. Although you may not realize it, you have seen Diophantine equations before: one of the most famous Diophantine equations is: We are not certain that McDonald's knows about Diophantine equations (actually we doubt that they do), but they use them! McDonald's sells Chicken McNuggets in packages of 6, 9 or 20 McNuggets. Thus, it is possible, for example, to buy exactly 15 McNuggets (with one package of 6 and a second package of 9), but it is not possible to buy exactly 16 nuggets, since no non- negative integer combination of 6's, 9's and 20's adds up to 16. To determine if it is possible to buy exactly n McNuggets, one has to solve a Diophantine equation: find non-negative integer values of a, b, and c, such that 6a + 9b + 20c = n. Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n"

  • Dojo addOnLoad, but is Dojo loaded?

    - by adamrice32
    I've encountered what seems like a chicken & egg problem, and have what I think is a logical solution. However, it occurred to me that others must have encountered something similar, so I figured I'd float it out there for the masses. The situation is that I want to use dojo's addOnLoad function to queue up a number of callbacks which should be executed after the DOM has completed rendering on the client side. So what I'm doing is as follows: <html> <head> <script type="text/javascript" src="dojo.xd.js"></script> ... </head> <body> ... <script type="text/javascript"> dojo.addOnLoad( ... ); dojo.addOnLoad( ... ); ... </script> </body> </html> Now, the issue is that I seem to be calling dojo.addOnLoad before the entire Dojo library has been downloaded the browser. This makes sense in a way, because the inline SCRIPT contents should be executed before the entire DOM is loaded (and the normal body onload callback is triggered). My question is this - is my approach sound, or would it make more sense to register a normal/standard body onload JavaScript callback to call a function, which does the same work that each of the dojo.addOnLoads is doing in the SCRIPT block. Of course, this begs the question, why would you ever then use dojo.addOnLoad if you're not guaranteed that the Dojo library will be loaded prior to using the library? Hopefully this situation makes sense to someone other than me. Seems like someone else may have encountered this situation. Thoughts? Best Regards, Adam Rice

  • self referencing object in JPA

    - by geoaxis
    Hello, I am trying to save a SystemUser entity in JPA. I also want to save certain things like who created the SystemUser and who last modified the system User as well. @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoCreated; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeCreated; @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoLastModified; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeLastModified; I also want to ensure that these values are not null when persisted. So If I use the NotNull JPA annotation, that is easily solved (along with reference to another entity) The problem description is simple, I cannot save rootuser without having rootuser in the system if I am to use a DataLoader class to persist JPA entity. Every other later user can be easily persisted with userWhoModified as the "systemuser" , but systemuser it's self cannot be added in this scheme. Is there a way so persist this first system user (I am thinking with SQL). This is a typical bootstrap (chicken or the egg) problem i suppose.

  • 'Forward-Compatible' Program Design

    - by Jeffrey Kern
    The majority of my questions I've asked here so far on StackOverflow have been how to implement individual concepts and techniques towards developing a software-based NES clone via the XNA environment. The small samples that I've thrown together on my PC work relatively great and everything. Except I hit a brick wall. How do I merge all of these samples together. Having proof-of-concept is amazing, except when you need it to go beyond just that. I now have samples strewn about that I'm trying to merge, some of them incomplete. And now I'm stuck with the chicken-and-the-egg situation of where I would like to incorporate these samples together, to make sure they work, but I cannot without test data. And I don't have tools to create test data, because they'd need to be based off of the individual pieces that need to be put together. In my mind, I'm having nightmares with circular reference. For my sample data, I am hoping to save it in XML and write a specification - and then make sample data by hand - but I'm too paranoid of manually creating an XML file full of incorrect data and blaming it on my code, or vice-versa. It doesn't help that the end-result of my work is graphic-oriented, which makes it interseting how a graphic on the screen can be visualized in XML Nodes. I guess, my question is this: What design patterns and disciplines exist in the coding world that address this type of concern? I've always relied on brute-force coding and restarting a project with a whole new code base in attempts to further along my goals, but I doubt that would be the best way to do so. Within my college career, the majority of my programming was to work on simple projects that came out of a book, or with a given correct data set and a verifyable result. I don't have that, as my own design documents that I am going by could be terribly wrong.

  • Overriding content_type for Rails Paperclip plugin

    - by Fotios
    I think I have a bit of a chicken and egg problem. I would like to set the content_type of a file uploaded via Paperclip. The problem is that the default content_type is only based on extension, but I'd like to base it on another module. I seem to be able to set the content_type with the before_post_process class Upload < ActiveRecord::Base has_attached_file :upload before_post_process :foo def foo logger.debug "Changing content_type" #This works self.upload.instance_write(:content_type,"foobar") # This fails because the file does not actually exist yet self.upload.instance_write(:content_type,file_type(self.upload.path) end # Returns the filetype based on file command (assume it works) def file_type(path) return `file -ib '#{path}'`.split(/;/)[0] end end But...I cannot base the content type on the file because Paperclip doesn't write the file until after_create. And I cannot seem to set the content_type after it has been saved or with the after_create callback (even back in the controller) So I would like to know if I can somehow get access to the actual file object (assume there are no processors doing anything to the original file) before it is saved, so that I can run the file_type command on that. Or is there a way to modify the content_type after the objects have been created.

  • getting OSGI Bundle from Eclipse IConfigurationElement

    - by Hayden Marchant
    Hi there, I am looking for extensions that implement a specific extension point, and am using the following acceptable method to do this: IExtensionRegistry extensionRegistry = Platform.getExtensionRegistry(); if (extensionRegistry == null) { return TEMPLATES; } IConfigurationElement[] config = extensionRegistry.getConfigurationElementsFor("com.ibm.im.launchpoint.templates.template"); I then would like to get the version of the defining bundle. I would use the following API, but the API for PluginVersionIdentifier is deprecated: for (IConfigurationElement e : config) { BlueprintTemplate template = new BlueprintTemplate(); IExtension declaringExtension = e.getDeclaringExtension(); PluginVersionIdentifier versionIdentifier = declaringExtension.getDeclaringPluginDescriptor().getVersionIdentifier(); I could not find an alternative in the new API - i.e. from a IConfigurationElement, how do I get the version id descriptor of the bundle. Obviously, from the Bundle I can get the version using the Bundle.getHeaders(), getting the Bundle-Version value - but how do I get the Bundle in the first place??? Platform.getBundle(bundleId) is not enough since I might have multiple versions of same bundle installed, and I need to know who I am. At the moment I have a chicken & egg situation, and the only solution I have is the above deprecated API.

  • Getting functions of inherited functions to be called

    Let's say I have a base class Animal from which a class Cow inherits, and a Barn class containing an Animal vector, and let's say the Animal class has a virtual function scream(), which Cow overrides. With the following code: Animal.h #ifndef _ANIMAL_H #define _ANIMAL_H #include <iostream> using namespace std; class Animal { public: Animal() {}; virtual void scream() {cout << "aaaAAAAAAAAAAGHHHHHHHHHH!!! ahhh..." << endl;} }; #endif /* _ANIMAL_H */ Cow.h #ifndef _COW_H #define _COW_H #include "Animal.h" class Cow: public Animal { public: Cow() {} void scream() {cout << "MOOooooOOOOOOOO!!!" << endl;} }; #endif /* _COW_H */ Barn.h #ifndef _BARN_H #define _BARN_H #include "Animal.h" #include <vector> class Barn { std::vector<Animal> animals; public: Barn() {} void insertAnimal(Animal animal) {animals.push_back(animal);} void tortureAnimals() { for(int a = 0; a < animals.size(); a++) animals[a].scream(); } }; #endif /* _BARN_H */ and finally main.cpp #include <stdlib.h> #include "Barn.h" #include "Cow.h" #include "Chicken.h" /* * */ int main(int argc, char** argv) { Barn barn; barn.insertAnimal(Cow()); barn.tortureAnimals(); return (EXIT_SUCCESS); } I get this output: aaaAAAAAAAAAAGHHHHHHHHHH!!! ahhh... How should I code this to get MOOooooOOOOOOOO!!! (and whatever other classes inheriting Animal wants scream() to be) instead?

  • Is it possible to have a mysql table accept a null value for a primary_key column referencing a diff

    - by Dr.Dredel
    I have a table that has a column which holds the id of a row in another table. However, when table A is being populated, table B may or may not have a row ready for table A. My question is, is it possible to have mysql prevent an invalid value from being entered but be ok with a NULL? or does a foreign key necessitate a valid related value? So... what I'm looking for (in pseudo code) is this: Table "person" id | name Table "people" id | group_name | person_id (foreign key id from table person) insert into person (1, 'joe'); insert into people (1, 'foo', 1)//kosher insert into people (1, 'foo', NULL)//also kosher insert into people(1, 'foo', 7)// should fail since there is no id 7 in the person table. The reason I need this is that I'm having a chicken and egg issue where it makes perfect sense for the rows in the people table to be created before hand (in this example, I'm creating the groups and would like them to pre-exist the people who join them). And I realize that THIS example is silly and I would just put the group id in the person table rather than vice-versa, but in my real-world problem that is not workable. Just curious if I need to allow any and all values in order to make this work, or if there's some way to allow for null.

  • How to run a javascript function before postback of asp.net button?

    - by Curtis White
    I'm using Javascript to create a DIV element and open up a new page by using onclientclick. This works great. Now, I need to write to it from the server side and this element must be created before it is posted back. How do I get the javascript to execute before the postback? Currently, I have to press the button twice because the element doesn't exist to write too on the first click. To be clear, I need this to execute before the "OnClick" of the button. Update: It looks like the Javascript function is called before the postback but the element is not updated until I run the second postback. Hmm Update: Unfortunately it is a bit more complicated then this. I'm creating a div tag in javascript to open a new window. Inside the div tag, I'm using a databinding syntax <%=Preview% so that I can get access to this element on the server side. From the server side, I'm injecting the code. I'm thinking this may be a chicken-egg problem but not sure. UPDATE! It is not the Javascript not running first. It is the databinding mechanism which is reading the blank variable before I'm able to set it. Hmm

  • protect purchased games to be downloaded on other pc

    - by JoJo
    I want to make a downloads managing system on my website, that when you purchase a download, you can always re-download it again for free. (i have read that Steam does something similar) The problem is, that someone would be able to create a account, purchase something and then give the account password to friends and family, so they can all download copies for free. Is there a way to prevent this? Or is it impossible.

  • Use XQuery to Access XML in Emacs

    - by Gregory Burd
    There you are working on a multi-MB/GB/TB XML document or set of documents, you want to be able to quickly query the content but you don't want to load the XML into a full-blown XML database, the time spent setting things up is simply too expensive. Why not combine a great open source editor, Emacs, and a great XML XQuery engine, Berkeley DB XML? That is exactly what Donnie Cameron did. Give it a try.
