  • Corona SDK: Quality of support and resources?

    - by Nick Wiggill
    I've not used Corona SDK before and am looking into it for a friend. (He is also considering Unity.) I wonder what the support is like for Corona? While Unity has a great many customers and so the Unity team can often not address issues directly, the community at large is very helpful and there are many excellent resources: tutorials, forum posts, code resources. What is Corona like in this regard, and by comparison?

  • Can anyone explain to me what problem Core Data solves?

    - by Curtis Sumpter
    Core Data seems to add a needless layer of complexity. If you want to save data created natively by the user in an app why not just use an object and then write the data all to SQLite or back to a server using a RESTful script if necessary. Android doesn't have Core Data (though if it has something similar I haven't seen it.). What the heck is the point of buggy CD except useless needless overhead for people who can't write SQL or CGI scripts?

  • Recover harddrive data

    - by gameshints
    I have a dell laptop that recently "died" (It would get the blue screen of death upon starting) and the hard drive would make a weird cyclic clicking noises. I wanted to see if I could use some tools on my linux machine to recover the data, so I plugged it into there. If I run "fdisk" I get: Disk /dev/sdb: 20.0 GB, 20003880960 bytes 64 heads, 32 sectors/track, 19077 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Disk identifier: 0x64651a0a Disk /dev/sdb doesn't contain a valid partition table Fine, the partition table is messed up. However if I run "testdisk" in attempt to fix the table, it freezes at this point, making the same cyclical clicking noises: Disk /dev/sdb - 20 GB / 18 GiB - CHS 19078 64 32 Analyse cylinder 158/19077: 00% I don't really care about the hard drive working again, and just the data, so I ran "gpart" to figure out where the partitions used to be. I got this: dev(/dev/sdb) mss(512) chs(19077/64/32)(LBA) #s(39069696) size(19077mb) * Warning: strange partition table magic 0x2A55. Primary partition(1) type: 222(0xDE)(UNKNOWN) size: 15mb #s(31429) s(63-31491) chs: (0/1/1)-(3/126/63)d (0/1/32)-(15/24/4)r hex: 00 01 01 00 DE 7E 3F 03 3F 00 00 00 C5 7A 00 00 Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) (BOOT) size: 19021mb #s(38956987) s(31492-38988478) chs: (4/0/1)-(895/126/63)d (15/24/5)-(19037/21/31)r hex: 80 00 01 04 07 7E FF 7F 04 7B 00 00 BB 6F 52 02 So I tried to mount just to the old NTFS partition, but got an error: sudo mount -o loop,ro,offset=16123904 -t ntfs /dev/sdb /mnt/usb NTFS signature is missing. Ugh. Okay. But then I tried to get a raw data dump by running dd if=/dev/sdb of=/home/erik/brokenhd skip=31492 count=38956987 But the file got up to 59885568 bytes, and made the same cyclical clicking noises. Obviously there is a bad sector, but I don't know what to do about it! The data is still there... if I view that 57MB file in textpad... I can see raw data from files. How can I get my data back? Thanks for any suggestions, Solution: I was able to recover about 90% of my data: Froze harddrive in freezer Used Ddrescue to make a copy of the drive Since Ddrescue wasn't able to get enough of my drive to use testdisk to recover my partitions/file system, I ended up using photorec to recover most of my files

  • Dealing with blackhat SEO companies and low quality link building competitors [closed]

    - by Mikko Ohtamaa
    I have often faced a case where the competitors of my client use SEO blackhat tactics where they contact a SEO company to do link building for their websites and products. Here is an example of a typical case of a fake blog created only for link building purposes A very low content article http://marshallfab.com/fundus-camera-explained.html in obvious fake blog: no author information, partially machine generated text, all blog posts are solely about link building Following the link you get to the promoted company page http://www.patternless.com/ ... which, unsurprisingly, links the SEO company homepage in the footer text http://www.affordableseofl.com/ ... who are not shy to advertise their Extremely aggressive SEO plan Does Google have any feedback channel where one could submit cases like this, so that Google would punish the link builders? Are there any means to bring these blackhat companies to pushame to damage their reputation?

  • Requesting quality analysis test cases up front of implementation/change

    - by arin
    Recently I have been assigned to work on a major requirement that falls between a change request and an improvement. The previous implementation was done (badly) by a senior developer that left the company and did so without leaving a trace of documentation. Here were my initial steps to approach this problem: Considering that the release date was fast approaching and there was no time for slip-ups, I initially asked if the requirement was a "must have". Since the requirement helped the product significantly in terms of usability, the answer was "If possible, yes". Knowing the wide-spread use and affects of this requirement, had it come to a point where the requirement could not be finished prior to release, I asked if it would be a viable option to thrash the current state and revert back to the state prior to the ex-senior implementation. The answer was "Most likely: no". Understanding that the requirement was coming from the higher management, and due to the complexity of it, I asked all usability test cases to be written prior to the implementation (by QA) and given to me, to aid me in the comprehension of this task. This was a big no-no for the folks at the management as they failed to understand this approach. Knowing that I had to insist on my request and the responsibility of this requirement, I insisted and have fallen out of favor with some of the folks, leaving me in a state of "baffledness". Basically, I was trying a test-driven approach to a high-risk, high-complexity and must-have requirement and trying to be safe rather than sorry. Is this approach wrong or have I approached it incorrectly? P.S.: The change request/improvement was cancelled and the implementation was reverted back to the prior state due to the complexity of the problem and lack of time. This only happened after a 2 hour long meeting with other seniors in order to convince the aforementioned folks.

  • Automated Website Testing/Sanity/Quality

    - by Jeff
    I am thinking about building a tool that starts from the root of a webpage and traverses the entire website gathering a list of resources such as CSS/HTML/Javascript files and then runs CSS/Javascript Lint + HTML Validator + Broken Link Finder. Before I start building something like this, I was wondering if this exists already? Thanks. I already searched Google quite a bit and couldn't find much.

  • How to reduce errors in dynamic language such as python, and improve my code quality

    - by Martin Luo
    I post the origin question in stackoverflow, some people suggest me to post here I've always have trouble with dynamic language like Python. Several problems: Typo error, I can use pylint to reduce some of these errors. But there's still some errors that pylint can not figure out. Object type error, I often forgot what type of the parameter is, int? str? some object? Also, forgot the type of some object in my code. Unit test might help me sometimes, but I'm not always have enough time to do UT. When I need a script to do a small job, the line of code are 100 - 200 lines, not big, but I don't have time to do the unit test, because I need to use the script as soon as possible. So, many errors appear. So, any idea on how to reduce the number of these problems?

  • Shooting Print Quality Pictures with a Camera Phone [Video]

    - by Jason Fitzpatrick
    Camera phones get a lot of grief for being underpowered but in this video tutorial the crew at SLR Lounge shows how basic technique and a good eye overcome all. Last year over at the photo blog FStoppers they put together a video showing off how you could use the iPhone as a fashion camera–essentially arguing that the camera wasn’t as important as the photographer. A lot of people said “Well yeah, but you had professional models and thousands of dollars in lighting equipment!” in reaction to the video. In turn the crew at SLR Lounge decided to make their own video showing that using only an iPhone camera and two reflectors (as well as an attractive but informal model). It of course helps to have some side kicks to help hold up your reflectors but the point still stands about modern camera phones being perfectly capable of good photos.

  • High quality/performance shared hosting (in northern Europe)

    - by Bente
    I work as a web developer on almost all levels. However, my typical customer is a 1-5 guys running some sort of consulting business. They have (or want) a web page with some kind of CMS so the can perform most (or all) editing themselves. I normally opt for Concrete5 as my default CMS because it's the most user friendly (and free) CMS I have found. My good recurring customers I host on my own server as a service, but I need a good host for the customers where I want to deliver a product and not be responsible for whatever may happen in the future. However, I still struggle with hosting! Experience shows that the typical ~1$ shared hosting is waaay to slow to run concrete5 smoothly, and a VPS is out of the question because I don't want to maintain it. So, where can I find as fast (from northern Europe), reliable, shared host where I can put a site and don't have to worry about the server going down or being unmaintained. I expect this should cost around $10-$20 but I'm open to all kinds of suggestions because different customers have different budgets.

  • migrating product and team from startup race to quality development

    - by thevikas
    This is year 3 and product is selling good enough. Now we need to enforce good software development practices. The goal is to monitor incoming bug reports and reduce them, allow never ending features and get ready for scaling 10x. The phrases "test-driven-development" and "continuous-integration" are not even understood by the team cause they were all in the first 2 year product race. Tech team size is 5. The question is how to sell/convince team and management about TDD/unit testing/coding standards/documentation - with economics. train the team to do more than just feature coding and start writing test units along - which looks like more work, means needs more time! how to plan for creating units for all backlog production code

  • PS2 Eyetoy Recording Quality

    - by Fire
    I have Ubuntu 12.04 LTS and a PS2 eyetoy "Namtai". Don't worry - this is not the sterotypical " how do I get my eyetoy working" question. My eyetoy works fine on Cheese, gucview and various other media software like VLC. However, It seems like I am capped by 25fps. If I recall, the eyetoy is much better than this (~60fps) but cannot find any way to fix this. The best program that I have have found is VLC because its advanced options allow you to change many settings but the framerate setting appears to have no effect. What software or settings can I use to take full advantage of my eyetoy? To give you the full information I wish to attach multiple eyetoys to the system and record from all of them. (Security software like motion and zoneminder, I couldn't get installed correctly on my system- so I haven't tried those yet). edit - I tried the same camera on a Windows system and the frame rate is much better in VLC compared to the Ubuntu system. Mind you with default settings in Windows VLC, the resolution isn't great. However, in Skype for example the resolution is amazing and the framerate is good. It seems there must be some settings I am missing somewhere because it doesn't appear to be a hardware problem...
