• Best Practice to return responses from service

  - by A9S6

  I am writing a SOAP based ASP.NET Web Service having a number of methods to deal with Client objects. e.g: int AddClient(Client c) = returns Client ID when successful List GetClients() Client GetClientInfo(int clientId) In the above methods, the return value/object for each method corresponds to the "all good" scenario i.e. A client Id will be returned if AddClient was successful or a List< of Client objects will be returned by GetClients. But what if an error occurs, how do I convey the error message to the caller? I was thinking of having a Response class: Response { StatusCode, StatusMessage, Details } where Details will hold the actual response but in that case the caller will have to cast the response every time. What are your views on the above? Is there a better solution?

• Brightness fn key adjustment problems

  - by npCoder

  My brightness function key controls work after setting grub boot parameter to "acpi_osi=" but using them I cannot adjust the brightness higher than around 70% (there is empty bar left over and I can't adjust higher) unless I go to Brightness & Lock settings manually than I can use the slider to adjust it higher... I primarily use intel_backlight to adjust my backlight and I am running Linux kernel 3.14.1 on Ubuntu 14.04 LTS on an ASUS X550LA Laptop when I try: cd /sys/class/backlight/intel_backlight cat max_brightness 937 cat brightness 811 It seems that I can only adjust to a maximum of 811 using the fn brightness controls If I instead do cd /sys/class/backlight/acpi_video0 cat max_brightness 10 cat brightness 4 cat actual_brightness 10 With the FN keys actual_brightness is not equal to the value returned from brightness on acip_video0 (which is always 4) but on intel_backlight actual_brightness = brightness The adjustment problem seemingly arises because both intel_backlight and acpi_video0 are trying to adjust brightness

• What is the general definition of something that can be included or excluded?

  - by gutch

  When an application presents a user with a list of items, it's pretty common that it permits the user to filter the items. Often a 'filter' feature is implemented as a set of include or exclude rules. For example: include all emails from [email protected], and exclude those emails without attachments I've seen this include/exclude pattern often; for example Maven and Google Analytics filter things this way. But now that I'm implementing something like this myself, I don't know what to call something that could be either included or excluded. In specific terms: If I have a database table of filter rules, each of which either includes or excludes matching items, what is an appropriate name of the field that stores include or exclude? When displaying a list of filters to a user, what is a good way to label the include or exclude value? (as a bonus, can anyone recommend a good implementation of this kind of filtering for inspiration?)

• What Is the Experience Revolution – and Why Does it Matter?

  - by Charles Knapp

  Customer experience is how your customer perceives the sum of their interactions with your organization throughout their buying, service delivery, and ownership experiences. In our highly connected online, phone, social, and mobile interactions, it’s easy to lose a dissatisfied customer – who can readily dissuade future customers. Nevertheless, great brand experiences still deliver top margins and low-cost repeat business. The Experience Revolution seamlessly connects customer-facing interactions with employee-facing CRM transactions. While your organization has invested in some of these capabilities, how well do the pieces work for your customers? Is it time for your organization to join the Experience Revolution? We invite you to join Oracle President Mark Hurd for an incredible, educational evening on June 25, from 6:00 – 9:00 p.m. in New York City.  Attend to see and learn: What leading brands do to win over customers How to unlock the value of customer experiences The bottom-line effect of great experiences Why doing nothing is not an option

• Naming conventions for newtype deconstructors (destructors?)

  - by Petr Pudlák

  Looking into Haskell's standard library we can see: newtype StateT s m a = StateT { runStateT :: s -> m (a, s) } newtype WrappedMonad m a = WrapMonad { unwrapMonad :: m a } newtype Sum a = Sum { getSum :: a } Apparently, there (at least) 3 different prefixes used to unwrap a value inside a newtype: un-, run- and get-. (Moreover run- and get- capitalizes the next letter while un- doesn't.) This seems confusing. Are there any reasons for that, or is that just a historical thing? If I design my own newtype, what prefix should I use and why?

• Debugging-Setting Consoles in Games

  - by ShrimpCrackers

  Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

• Is it bad style to redundantly check a condition?

  - by mcwise

  I often get to positions in my code where I find myself checking a specific condition over and over again. I want to give you a small example: suppose there is a text file which contains lines starting with "a", lines starting with "b" and other lines and I actually only want to work with the first two sort of lines. My code would look something like this (using python, but read it as pseudocode): # ... clear_lines() # removes every other line than those starting with "a" or "b" for line in lines: if (line.startsWith("a")): # do stuff if (line.startsWith("b")): # magic else: # this else is redundant, I already made sure there is no else-case # by using clear_lines() # ... You can imagine I won't only check this condition here, but maybe also in other functions and so on. Do you think of it as noise or does it add some value to my code?

• Should the English website use href="x-default" when it doesn't auto-redirect to the user's language or country?

  - by Noam

  For each URL on my site, I'm auto-redirecting according to header accept language. The site arch is English version: http://mydomain.com/page Spanish version http://es.mydomaina.com/page etc.. The english version is displayed unless I'm seeing a specific language other than en and that I support in the header, and then a redirect occurs. Google says this: For language/country selectors or auto-redirecting homepages, you should add an annotation for the hreflang value "x-default" as well: My pages aren't language selectors, nor are they the homepage. But I am auto-redirecting. My question is, should my english version be hreflang="x-default" or/and hrefland="en"?

• SEO for images: can I use a different (cookieless) domain?

  - by Oliver

  Hello, We want to increase the value of some of our important images by means of SEO, and we want to start serving them from a different, i.e. cookieless, domain. We want to go from http://www.example.com/images/1234.jpg to http://www.example.com/germany/bavaria/landscape.jpg which can easily be done via URL rewriting. Then on the other hand, we would like to serve the image from a completely different domain, let's say http://www.examplestatic.com/germany/bavaria/landscape.jpg, to save the overhead of sending the cookie from www.example.com. Somehow I feel that this is not a good idea because I move the image away from the content by putting it on a different domain. Can anyone shed some light on this problem? Naturally, I would just use a different subdomain, e.g. img.example.com, but we already use subdomains for languages and our cookies are valid for all subdomains of example.com, so this won't help. I'd really appreciate any hints. Cheers,

• Importance of certifications for Java programmer without BS degree?

  - by programmx10

  I've read some posts here and other places about how a lot of people don't put much value in certifications but I am beginning to think it may be necessary for me at this point to be able to move to a bigger company, etc. I currently work as a Java programmer with a startup and worked with a small company before that. Now that I'm applying with larger companies the hr people / recruiters have been asking a lot about certifications and some have directly suggested that someone in my position should probably get a few (they were trying to be helpful) since I haven't completed a BS degree yet (I bounced around a bit in college and ended up not finishing but have enough units to finish eventually, just its not something I can do nearly as easily as getting certifications). Anyways, just curious about what people think for someone in my situation where I do have an interested in working for large companies and do not currently have a BS degree (but do have experience already in the field). Any advice on which certifications beyond the SCJP would be appreciated as well

• SSL certificates - best bang for your buck [closed]

  - by Dunnie

  I am in the process of setting up an online store. This is the first project I have attempted which will require a good level of security, so I recognise that an decent SSL certificate is a must. My current (albeit admittedly basic) understanding of the options are: DV SSL - more or less pointless, as provides no verification. OV SSL - better, as provides a basic level of organisational verification. EV SSL - 'better, full' verification, but much more expensive. As this is a new business venture, and budgets are tight, which option provides the best bang for my buck? I have read questions such as EV SSL Certificates - does anyone care? which suggest that EV certificates are a bit of a con. Does this mean that OV certificates offer better value for money, especially for new businesses with shallow pockets?

• Is Unity's Random seeded automatically?

  - by Lohoris

  I seem to recall Unity's Random is automatically seeded; checking the documentation it doesn't say it outright, but a certain interpretation of their words might seem to imply it. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. This prevents the same run of values from occurring each time a game is played and thus avoids predictable gameplay. However, it is sometimes useful to produce the same run of pseudo-random values on demand by setting the seed yourself. (emphasis added)

• What is good side of PageRank?

  - by SharkTheDark

  I am doing research about backlinks/PR/SEO/Search Result position and all I read about is that PageRank is not important, that it worth before but now it's not important at all. Only thing I found useful about it that is "change Search Result position", but ONLY if there are two sites with same keywords and same text content value, then Search Engine will check which site has higher PR and place that site above lowest one. Google counts PR importance as 20% for displaying search rankings, and Yahoo! is like 3%... Correct me if I am wrong... Is there any other good thing from it?

• PeopleTools 8.54 Pre-Release Notes Available

  - by Matthew Haavisto

  PeopleSoft's PeopleTools recently published pre-release notes for PeopleTools 8.54.  Pre-release notes provide more functional and technical details than the release value proposition. This document describes how enhancements function within the context of the greater business process. This added level of detail should enable project teams to answer the following questions: What delivered functionality will change? How will an upgrade or new implementation affect other systems? How will these changes affect the organization? After the project team has reviewed and analyzed the pre-release notes, business decision makers should be able to determine whether to allocate budget and initiate implementation plans. This document covers the following subjects: Platform support enhancements Development tools enhancements System administration tools enhancements Reporting and analytic tools enhancements Integration tools enhancements Lifecycle management tools enhancements Accessibility PeopleSoft Interaction Hub enhancements.

• Why is 2^16 a "special" number?

  OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

• We Heart Discussion Forums (and Know You Do Too)

  - by oracletechnet

  It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

• Security settings for this service require 'Basic' Authentication

  - by Jake Rutherford

  Had an issue calling WCF service today. The following exception was being thrown when service was called:WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/35320229 Exception: System.ServiceModel.ServiceActivationException: The service '/InteliChartVendorCommunication/VendorService.svc' cannot be activated due to an exception during compilation.  The exception message is: Security settings for this service require 'Basic' Authentication but it is not enabled for the IIS application that hosts this service..Ensured Basic authentication was indeed enabled in IIS before getting stumped on what actual issue could be. Turns out it was CustomErrors setting. Value was set to "off" vs "Off". Would have expected different exception from .NET (i.e. web.config parse exception) but it works now either way.

• How to quantify product work in Resume?

  - by mob1lejunkie

  One of things I do in my Resume is try to quantify the impact my work has had in the particular company I was with at the time. The reason is it shows the value my work had added to the business. Is this what you guys do as well or am I the only one? In my previous job this was easy as I worked on short/medium internal applications and it was fairly easy to measure end result. For example, external consulting company quoted $50,000 for an application Business Services department wanted I completed it in 3 days so I say I saved the company $48,000. I have been in my current job for 3 years but all of it has been on 1 single well established product. About 30% work is maintenance and 70% work is on new modules. I have worked on various modules like API (WCF), Security (2 factor authentication), etc. How should I quantify work on modules? Many thanks.
