  • Is type safety worth the trade-offs?

    - by Prof Plum
    I began coding in in Python primarily where there is no type safety, then moved to C# and Java where there is. I found that I could work a bit more quickly and with less headaches in Python, but then again, my C# and Java apps are at much higher level of complexity so I have never given Python a true stress test I suppose. The Java and C# camps make it sound like without the type safety in place, most people would be running into all sorts of horrible bugs left an right and it would be more trouble than its worth. This is not a language comparison, so please do not address issues like compiled vs interpreted. Is type safety worth the hit to speed of development and flexibilty? WHY? to the people who wanted an example of the opinion that dynamic typing is faster: "Use a dynamically typed language during development. It gives you faster feedback, turn-around time, and development speed." - http://blog.jayway.com/2010/04/14/static-typing-is-the-root-of-all-evil/

  • Safety using $_SERVER variables

    - by DiogoNeves
    Hi all, I'm working on a system that relies in $_SERVER['REMOTE_ADDR'] to get the user address and check it against a white list of addresses. Is this approach safe? Or is there a way of forcing values in superglobal variables? Thank you, Diogo

  • flickr, other account types not appearing in online-accounts

    - by Fen
    Using Shotwell, I discovered that to publish to Flickr I need to set up an online account. But the online-accounts system settings only has support for Google, Facebook, Windows Live, Microsoft Exchange and Enterprise Login (Kerberos). How do I add account types? These appear to be properly installed (dpkg-reconfigure returns silently): gnome-control-center-signon is already the newest version. account-plugin-yahoo is already the newest version. account-plugin-flickr is already the newest version. Here's the config file (I think): > cat /usr/share/applications/gnome-online-accounts-panel.desktop [Desktop Entry] Name=Online Accounts Comment=Manage online accounts Exec=gnome-control-center online-accounts Icon=goa-panel Terminal=false Type=Application StartupNotify=true Categories=GNOME;GTK;Settings;DesktopSettings;X-GNOME-Settings-Panel;X-GNOME-PersonalSettings; OnlyShowIn=GNOME;XFCE X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=gnome-control-center X-GNOME-Bugzilla-Component=Online Accounts X-GNOME-Bugzilla-Version=3.4.2 X-GNOME-Settings-Panel=online-accounts # Translators: those are keywords for the online-accounts control-center panel Keywords=Google;Facebook;Flickr;Twitter;Yahoo;Web;Online;Chat;Calendar;Mail;Contact; X-Ubuntu-Gettext-Domain=gnome-control-center-2.0 History: Started out with Ubuntu (64-bit), then in 12.04 installed xubuntu-desktop and have been using that.

  • Google adwords API - credit card safety question

    - by anon
    Hi, Google is asking me to fax credit card xerox in order to activate adwords API in MCC. This really sucks imo... they could have had prepaid option. In any case, my questions: 1) Are there alternatives to this - is there a 3rd party provider who will give me this service without me sending them the credit card info? 2) How secure is it to send my credit card fax via some online fax service? 3) Do you think they will reject the application if I hide my CVV number in the fax? Any other thoughts appreciated :) thanks

  • What are the safety benefits of a type system?

    - by vandros526
    In Javascript: The Good Parts by Douglas Crockford, he mentions in his inheritance chapter, "The other benefit of classical inheritance is that it includes the specification of a system of types. This mostly frees the programmer from having to write explicit casting operations, which is a very good thing because when casting, the safety benefits of a type system are lost." So first of all, what actually is safety? protection against data corruption, or hackers, or system malfunctions, etc? What are the safety benefits of a type system? What makes a type system different that allows it to provide these safety benefits?

  • NRF Online Merchandising Workshop: Where Online Retailers Are Focusing for Holiday and Beyond

    - by Rose Spicer-Oracle
    0 0 1 1204 6863 Oracle Corporation 57 16 8051 14.0 Normal 0 false false false EN-US JA X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:Cambria; mso-ascii-font-family:Cambria; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Cambria; mso-hansi-theme-font:minor-latin;} Last month we attended the NRF Online Merchandising Workshop in LA, and it was a great opportunity to catch up with our customers, meet new retailers, and hear some great presentations from VF Corporation, Zazzle, Julep Beauty, Backcountry, eBags and more. The one-on-one conversations with Merchants and the keynote presentations carry the same themes across companies of all sizes and across verticals. With only 125 days left (and counting) until Black Friday, these conversations provided some great insight in to what’s top of mind for retailers during the most stressful time of their year, and a sneak peek in to what they will deliver this holiday season.  Some of the most popular topics were: When to start promoting for holiday: seems like a funny conversation to have in July, but a number of retailers said they already had their holiday shopping gift guides live on their site, and it was attracting a significant portion of their onsite traffic. When it comes to timing, most retailers were questioning when to begin their holiday promotions -- carefully balancing when to release pricing and specials, and knowing that customers are holding out for last-minute deals and price drops. Many retailers noted the frustrations around transparent pricing by Amazon and a few other mega-retailers last year, publishing their “lowest prices of the season” as early as October – ensuring shoppers that those prices were the best they could get all season long. Many retailers felt their hands were forced to drop prices. Others kept their set pricing with negative customer reaction, causing some to miss their holiday goals. The pressure is on, and most retailers identified November 1 as their target start date for the holiday promotions blitz. Some are even waiting for the big guys to release their “lowest prices of the season” guides and will then follow suit.      Attribution is tough – and a huge focus: understanding the path to conversion is a tough nut to crack, especially in the new omnichannel world where consumers use multiple touchpoints to make a single purchase, and internal management wants to know hard data. This has lead many retailers to invest in attribution; carefully tracking their online marketing efforts to determine what gets “credit” for the sale, instead of giving credit to the “last click.” Retailers noted that it is very difficult to determine the numbers when online and offline worlds collide – like when a shopper uses digital channels for research and then makes a purchase in a store. As one of the presenters from The North Face mentioned in her keynote, a key to enabling better customer service and satisfaction when it comes to converged online and offline sales is training the in-store staff, and creating a culture where it eventually “doesn’t matter what group gets the credit” if they all add to the sale. No doubt, the area of attribution will be a big area of retail investment in the coming years.      How to plan for the converged world: planning to ensure inventory gets where it needs to be was another concern. In conversations with retailers, we advised them to analyze customer patterns: where shoppers purchase items, where the items were sourced from and even where items are returned. This analysis is very valuable in determining inventory plans. From there, retailers can more accurately plan and allocate inventory to support both the online and offline customer behavior. As we head into the holiday season, the need for accurate enterprise-wide inventory visibility, and providing that information to associates, is even more critical to the brand-wide customer experience.       Improving the search / navigation / usability of the site(s): Aside from some of the big ideas and standard holiday pricing pressure, most conversations we had centered around continuing to improve the basics of the site. Reinvesting in search and navigation came up time and time again (FitForCommerce blogged about what a big topic it was at the event as well). Obviously getting shoppers on their path quickly and allowing them to find what they need fast is critical, but it was definitely interesting to hear just how much effort is still going in to honing the search and navigation experience. Adding new elements to search and navigation like typeahed, inventive navigation refinements, and new navigation categories like gift guides, specialized boutiques and flash sales were top of mind, in addition to searchandising and making search-driven product recommendations. (Oracle can help!)       Reducing cart abandonment: always a hot topic that is top of mind for every online retailer. Getting shoppers to the cart is often less then half the battle; getting them to click “buy” and complete the transaction is much more difficult. While retailers carefully study the checkout process and where shoppers tend to bounce, they know that how they design their checkout page is critical. We’re all online shoppers in our personal lives and we know how frustrating it can be when total prices are not transparent (i.e. shipping, processing, taxes is not included until the very last possible screen before clicking that buy button). Online retailers are struggling with where in the checkout process to surface the total price to be charged to reduce cart abandonment, while not showing the total figure too early in the process that it keeps shoppers from getting to checkout altogether. Recent research shows that providing total pricing prior to the checkout process dramatically reduces cart abandonment – as it serves as a filter to those shopping within a specific price band. Much of the cart abandonment discussion leads us to…       The free shipping / free returns question: it’s no secret that because of Amazon and programs like Prime, consumers expect free shipping, much to the chagrin of the smaller retailer. The reality is that if you’re not a mega-retailer, shipping is an expensive part of doing business that doesn’t allow most retailers to keep their prices low and offer free shipping. This has many retailers venturing out on the “free returns” path, especially in apparel. A number of retailers we spoke with are testing a flat rate shipping fee with free returns to see if they can crack the price threshold where shoppers are willing to pay for shipping with an added service. But, free shipping remains king.      Social ads and retargeting: they are working, but do they turn off consumers? That’s the big question. Every retailer we spoke with during a roundtable on the topic said that social ads and retargeting (where that pair of boots you’re been eyeing on a site magically follows you around the Internet) work and are meeting campaign goals. The larger question many retailers are asking is if this type of tactic is turning off a large number of shoppers, even if these campaigns are meeting their early goals. Retailers also mentioned that Facebook ads are working very well for them, especially when it comes to new customer acquisition, serving as a complimentary a channel to SEO when it comes to engaging new customers. While there are always new things to experiment with in retail, standard challenges are top of mind as retailers scramble to get ready for holiday. It will undoubtedly be another record-breaking online shopping season, but as retailers get more and more advanced with each Black Friday, expect some exciting things. This excitement needs to be backed by sound solutions and optimized operations. Then again, consumers are expecting more than ever, so I don’t doubt that retailers are already thinking about the possibilities of holiday 2015… and beyond.

  • What is the difference between safety and security?

    - by Lernkurve
    Question What is the difference between safety and security in the context of information management or computer science? Elaboration This could be the canonical answer for people searching for it. Let me know if superuser.com is the wrong site for this question. I have, of course, googled it and haven't found an answer that seemed short and to the point. Wikipedia wasn't very helpful either: safety, information security.

  • Best choice for a personal "online backup" in Europe

    - by marc_s
    I'm looking for an online backup solution for personal use - besides all the usual requirements (like not too expensive, since it's for personal use), I'd like to add two requirements to it: data center should be in Europe (I don't want my personal data stored in the US, when the next crazed president comes along and wants to confiscate and rifle through everybody's files.....) the online backup store should be accessible through a drive letter in cmd.exe So far, I've looked at a few services, but none have totally convinced me: Dropbox is looking ok, but they insist on creating a silly "My Dropbox" directory in my data path - and there's no way I can choose that name. Sorry - "My everything" is for dummies - I don't like that, I like to name my files and folders according to my liking LiveDrive is OK, too - they offer European storage, drive letter and all - but those drive letters are only available in the Windows Explorer - and not on the cmd.exe command line :-( and since I do 99% of my work on the command line, this is a major drawback..... Any other services I haven't looked at worth checking out? Marc

  • Unlimited and multi-computer online storage solutions with automatic backup

    - by JRL
    As the title says, what are the existing online storage solutions that provide: unlimited storage automatic backup and allow for an unlimited number of computers (use not tied to a single computer)? There are several existing questions on this site related to online storage solutions, but none that is specifically targeted to what I want, so I thought I'd ask the question. This wikipedia article lists some of them, are there others? How do they compare in terms of price, feature set and ease of use? Update: Kinda disappointed no one has any answers to this so far. JungleDisk looks promising, anyone have experience with it? Update 2: To answer the comments, what I'm looking for definitely DOES exist. These solutions all seem to fit the bill: BackMii CrashPlan DataPreserve Humyo JungleDisk KeepVault SpiderOak And some of them are quite cheap (CrashPlan is $100 a year). For unlimited space and computers, I'd say that's pretty good. Does anyone have experience with CrashPlan or any other of the above solutions?

  • Online Multiplayer Game Architecture [on hold]

    - by Eric
    I am just starting to research online multiplayer game development and I have a high-level architectural question regarding how online multiple games function. I have server-side and client-side programming experience, and I understand how AJAX-esque transfer protocol operates. What I don't understand yet is how online multiple fits into all of that. For example, an online Tetris multiplayer game. Would both players have the entire Tetris game built out on their client-side and then get pushed "moves" from the other player via some AJAX-esque mechanism, in which case each client would have to be constantly listening via JavaScript for inbound "moves" and update the client appropriately? Or would each client build out the aesthetics and run a virtual server per game to which each client connects and thus pull and push commands in real-time via something like web sockets? I apologize if this question is too high-level and general, but I couldn't find anything online that offered this high-level of a perspective on the topic.

  • How do you troubleshoot Family Safety reports

    - by Klas Mellbourn
    I have set up Microsoft Family Safety in Windows 8 for my daughter's account. At first I got meaningful reports via e-mail each week. But then the e-mails started reporting no activity, even though my daughter still uses the computer. The e-mails are still sent to me, but indicate that she is not using the computer at all. Family Safety is definitely still active on the computer. It limits how long she can use the computer. So only the e-mail reports are buggy. I don't know how to troubleshoot this since the e-mails are generated by Microsoft. Any ideas?

  • Developing online invoicing and inventory application.

    - by Rohit
    My clients are using a desktop version of my inventory solution that I developed using .NET. I want to make an online version so that data is available centrally and clients can work from any location. I searched using Google to find similar tools and found few. I want to know what type of security considerations to take while designing such an application? Some clients can't afford dedicated server cost. What if I use shared hosting only? What are the risks of shared hosting?

  • Online games programming basics

    - by Renkon
    I am writing with regard to an issue I am having nowadays. I have come up with an interesting idea of making an online game in C#, yet I do not have the knowledge to work with more than a player. Basic games like a TIC-TAC-TOE or a SNAKE were done already, and I would like to do a simple, but online, game. Would you mind giving me some tutorials or guides related to that? I would really like to learn how to work online with the client/server structure (though, I do know the basics about that structure). I look forward to reading from you. Yours faithfully, Renkon.
