• Are Uninterruptible Power Supply (UPS) at home really a worthwhile investment for home computing? [c

  - by Jian Lin

  Possible Duplicate: Is a UPS a good investment for a home machine? I have 2 Uninterruptible power supplies at home, but they seem to expire after 5 years or so. During this 5 years, it maybe saved the computer from turning off twice. But I wonder, I often save my documents every 10 minutes. So the most I can lose is 10 minute worth of work. Not to mention that, I may not be editing anything when the power is out. Also, when the UPS expires, one of them will give out beeping sound once in a while, probably signaling the changing of the battery. So I can either buy 2 new UPS or just buy 2 power outlets instead. 2 UPS, costing $160 to $250 roughly, can it be really worth it if it can save your computer from powering off for just 2 times? What are the alternatives?

• Database version control resources

  - by Wes McClure

  In the process of creating my own DB VCS tool tsqlmigrations.codeplex.com I ran into several good resources to help guide me along the way in reviewing existing offerings and in concepts that would be needed in a good DB VCS.  This is my list of helpful links that others can use to understand some of the concepts and some of the tools in existence.  In the next few posts I will try to explain how I used these to create TSqlMigrations.   Blogs entries Three rules for database work - K.

• Is Perl still a useful, viable language?

  - by Bob

  I know it may have been asked before, but here goes nothing... Is Perl still something that would be considered useful? If someone was a new programmer (either completely new to programming or just a few month/years of experience) would Perl be something to be considered worthwhile to learn? Is Perl still used with frequency? Is it still popular? Or is Perl dying out compared to languages like Python, Ruby, PHP, ASP, .NET, etc.? Basically it boils down to this: Is it still used/is it still used frequently? If yes, is it dying? If no, will it make a come back? Is it something that would be worth learning? How does it compare in demand to languages like Python in both popularity and usability/viability? Could languages like Python or Ruby be considered replacements for Perl? Also, will newer versions of Perl really bring a large improvement to the Perl community, and perhaps bring Perl back to centerstage compared to other languages? EDIT: Okay, I suppose here's a better, reworded question: Is Perl still growing, or is it "dying"? Is it still a language worth learning and using? What projects does it really "shine" in compared to other languages? What makes Perl a language to choose? Essentially: is Perl growing obsolete compared to other languages, and if so, do you expect that to change, or to continue? And thank you to everyone who has answered so far, the discussion has been really interesting!

• Advise on how to move from a .net developer role to a web developer role

  - by dermd

  I've been working primarily as a .net developer for the past 4 years for a financial services company. I've worked on .net 1.1, 2.0, 3.5 and have done the 3.5 enterprise app developer cert (not that that's worth a whole lot!). Before that I worked as a java developer with a bit of Flex thrown in for just over a year. My educational background is an Electronic and computer engineering degree, a higher diploma in systems analysis as well as one in web development (this was mainly java - JSP, Spring, etc) and a science masters in software design and development. I really feel like a change and would like to move to a different field to experience something different. I've done some courses in RoR and played around with it a bit in my spare time. Similarly I've done various web and mobile courses and done up some mobile webapps along with android and ios equivalents (haven't tried pushing them up to the app stores yet but may be worth tidying them up and doing that). I currently work long enough hours so find it hard to find time to work on too many side projects to get a decent portfolio together. But when I do work on the web stuff I do find it really enjoyable so think it's something I'd like to do full time. However, since my experience is pretty much all .net and financial services I find it very hard to get my foot in the door anywhere or get past a phone screen unless their specifically looking for someone with .net knowledge. What is the best way to move into a web development role without starting from scratch again. I do think a lot of the skills I have translate over but I seem to just get paired with .net jobs whenever I look around? Apart from js, jquery, html5, objective C are there any other technologies I should be looking into?

• What's the value of a Facebook fan?

  - by David Dorf

  In his blog posting titled "Why Each Facebook Fan Is Worth $2,000 to J. Crew," Joe Skorupa lays out a simplistic calculation for assigning a value to social media efforts within Facebook. While I don't believe the metric, at least its a metric that can be applied consistently. Trying to explain the ROI to management to start a program, then benchmarking to show progress isn't straightforward at all. Social media isn't really mature enough to have hard-and-fast rules around valuation (yet). When I'm asked by retailers how to measure social media efforts, I usually fess-up and say I can't show an ROI but the investment is so low you might was well take a risk. Intuitively, it just seems like a good way to interact with consumers, and since your competition is doing it, you better do it as well. Vitrue, a social media management company, has calculated a fan as being worth $3.60 per year based on impressions generated in Facebook's news feed. That means a fan base of 1 million translates into at least $3.6 million in equivalent media over a year. Don't believe that number either? Fine, Vitrue now has a tool that let's you adjust the earned media value of a fan. Jump over to http://evaluator.vitrue.com/ and enter your brand's Facebook URL to get an assessment of the current value and potential value. For fun, I compared Abercrombie & Fitch (1,077,480 fans), Gap (567,772 fans), and Wet Seal (294,479 fans). The image below shows the results assuming the default $5 earned media value for a fan. The calculation is more complicated than just counting fans. It also accounts for postings and comments. Its possible for a brand with fewer fans to have a higher value based on frequency and relevancy of posts. The tool gathers data via the Social Graph API for the past 30 days of activity. I'm not sure this tool assigns the correct value either, but hey, its a great start.

• What have you learnt that has a steep learning curve?

  - by Jonathan Khoo

  Recently, I've invested time in learning the intricacies of Git and it has got me thinking about time and learning. (My previous experience with version control systems was only limited use of CVS and SVN.) It took me a whole day's worth of reading to be able to understand the concepts and differences of Git. There are an infinite number of things available for us to learn. Some, more useful than others. I don't know Fortran - I'm relatively young. But looking back at the preceding years of my life, I notice that I'm busier and busier as time goes on. The amount of things I have to get through in a day is increasingly out of my control. It doesn't take a genius to extrapolate that information and realise I'll have even less time in the future - unless I get fired, but I have no strong plans relating to that idea for now. So, given that I have much more time and energy now than I will have in the future: what have you learnt, that has a steep learning curve, that you would possibly recommend to a fellow programmer? Edit: I've stumbled upon the excellent question What programming skills have provided you the best return on investment? and hav realised that my way of approaching how to spend learning time was naive - it doesn't matter if ten useful concepts can be learnt in the time of one if they're worth it.

• Useful certifications for a young programmer

  - by Alain

  As @Paddyslacker elegantly stated in Are certifications worth it? The main purpose of certifications is to make money for the certifying body. I am a fairly young developer, with only an undergraduate degree, and my job is (graciously) offering to sponsor some professional development of my choice (provided it can be argued that it will contribute to the quality of work I do for them). A search online offers a slew of (mostly worthless) certifications one can attain. I'm wondering if there are any that are actually recognized in the (North American) industry as an asset. My local university promoted CIPS (I.S.P., ITCP) at the time I was graduating, but for all I can tell it's just the one that happened to get its foot in the door. It's certainly money grubbing - with a $205 a year fee. So are there any such certifications that provide useful credentials? To better define 'useful' - would it benefit full time developers, or is it only something worth while to the self-employed? Would any certifications lead me to being considered for higher wages, or can that only be achieved with more experience and an higher-level degree?

• Thumbs Up or Thumbs Down – Intel Debuts Prototype Palm-Reading Tech to Replace Passwords [Poll]

  - by Asian Angel

  This week Intel debuted prototype palm-reading tech that could serve as a replacement for our current password system. Our question for you today is do you think this is the right direction to go for better security or do you feel this is a mistake? Photo courtesy of Jane Rahman. Needless to say password security breaches have been a hot topic as of late, so perhaps a whole new security model is in order. It would definitely eliminate the need to remember a large volume of passwords along with circumventing the problem of poor password creation/selection. At the same time the new technology would still be in the ‘early stages’ of development and may not work as well as people would like. Long-term refinement would definitely improve its performance, but would it really be worth pursuing versus the actual benefits? From the blog post: Intel researcher Sridhar Iyendar demonstrated the technology at Intel’s Developer Forum this week. Waving a hand in front of a “palm vein” detector on a computer, one of Iyendar’s assistants was logged into Windows 7, was able to view his bank account, and then once he moved away the computer locked Windows and went into sleeping mode.

• unit level testing, agile, and refactoring

  - by dsollen

  I'm working on a very agile development system, a small number of people with my doing the vast majority of progaming myself. I've gotten to the testing phase and find myself writing mostly functional level testing, which I should in theory be leavning for our tester (in practice I don't entirely...trust our tester to detect and identify defects enough to leave him the sole writter of functional tests). In theory what I should be writing is Unit level tests. However, I'm not sure it's worth the expense. Unit testing takes some time to do, more then functional testing since I have to set up mocks and plugs into smaller units that weren't design to run in issolation. More importantly, I find I refactor and redesign heavily-part of this is due to my inherriting code that needed heavy redesign and is still being cleaned up, but even once I've finished removing parts that need work I'm sure in the act of expanding the code I'll still do a decent amount of refactoring and redesign. It feels as if I will break my unit tests, forcing wasted time to refactor them as well, often due to unit test, by definition, having to be coupled so closely to the code structure. So.is it worth all the wasted time when functional tests, that will never break when I refactor/redesign, should find most defects? Do unit tests really provide that much extra defect detetection over through functional? and how does one create good unit tests that work with very quick and agile code that is modified rapidly? ps, I would be fine/happy with links to anything one considers an excellent resource for how to 'do' unit testing in a highly changing enviroment. edit: to clarify I am doing a bit of very unoffical TDD, I just seem to be writing tests on what would be considered a functional level rather then unit level. I think part of this is becaus I own nearly all of the project I don't feel I need to limit the scope as much; and part of it is that it's daunting to think of trying to go back and retroactively add the unit tests needed to cover enough code that I can feel comfortable testing only a unit without the full functionality and trust that unit still works with the rest of the units.

• Big AdventureWorks2012

  - by jamiet

  Last week I launched AdventureWorks on Azure, an initiative to make SQL Azure accessible to anyone, in my blog post AdventureWorks2012 now available for all on SQL Azure. Since then I think its fair to say that the reaction has been lukewarm with 31 insertions into the [dbo].[SqlFamily] table and only 8 donations via PayPal to support it; on the other hand those 8 donators have been incredibly generous and we nearly have enough in the bank to cover a full year’s worth of availability. It was always my intention to try and make this offering more appealing and to that end I have used an adapted version of Adam Machanic’s make_big_adventure.sql script to massively increase the amount of data in the database and give the community more scope to really push SQL Azure and see what it is capable of. There are now two new tables in the database: [dbo].[bigProduct] with 25200 rows [dbo].[bigTransactionHistory] with 7827579 rows The credentials to login and use AdventureWorks on Azure are as they were before: Server mhknbn2kdz.database.windows.net Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly Remember, if you want to support AdventureWorks on Azure simply click here to launch a pre-populated PayPal Send Money form - all you have to do is login, fill in an amount, and click Send. We need more donations to keep this up and running so if you think this is useful and worth supporting, please please donate.   I mentioned that I had to adapt Adam’s script, the main reasons being: Cross-database queries are not yet supported in SQL Azure so I had to create a local copy of [dbo].[spt_values] rather than reference that in [master] SELECT…INTO is not supported in SQL Azure The 1GB limit of SQLAzure web edition meant that there would not be enough space to store all the data generated by Adam’s script so I had to decrease the total number of rows. The amended script is available on my SkyDrive at https://skydrive.live.com/redir.aspx?cid=550f681dad532637&resid=550F681DAD532637!16756&parid=550F681DAD532637!16755 @Jamiet

• I've been hired on as a entry-level game developer at a company and have little/no experience in API programming, what should I expect?

  - by Mr. Geneth

  So, I've been hired on as an entry level game developer with little/no experience working with any API other than Win32. This will be an overall learning experience for me as a person and I have gone over this multiple times with the boss and he has no problem with my inexperience. He says that if I'm not worth it now, I will be later. This gives me confidence, but I still feel that I should know a lot more before tackling this position. I would be stupid to pass it up. This is one of my favorite places to come for advice and help and have tried to just accept this, but it just keeps bothering that I can't go in knowing how to at least do the basics. I want to give the company its money's worth. Ya know? My questions are: What should I expect from the other programmers in this project (In terms of patience with me and working together, and being taught)? Is this normal? Any other advice on this sort of thing would be wonderful. I just want to feel comfortable with it.

• New Cloud Security Book: Securing the Cloud by Vic Winkler

  - by user12608550

  It's rare that I read a technical book straight through; I usually read key chapters and save the rest for later reference. But Winkler's book, written by an accomplished and highly experienced security professional, was worth a complete read, cover to cover. Of the recently published cloud security books, such as... Cloud Security and Privacy: An Enterprise Perspective on Risks and Compliance, by Tim Mather, Subra Kumaraswamy, and Shahed Latif; O'Reilly Media Inc, 2009; Cloud Computing: Implementation, Management, and Security, by John Rittenhouse and James Ransome; CRC Press 2010; Cloud Security: A Comprehensive Guide to Secure Cloud Computing, by Ronald Krutz and Russell Vines; Wiley Publishing Inc, 2010 ...Securing the Cloud is the most useful and informative about all aspects of cloud security. Clearly, through his experience, the author has thought through many practical issues of securing large, virtualized IT installations. His Chapter 6 on Best Practices and Chapter 9 with its valuable checklists are worth the price of the book. If you are among the many new cloud computing professionals, Securing the Cloud is an essential reference for your work.

• Hallmarks of a Professional PHP Programmer

  - by Scotty C.

  I'm a 19 year old student who really REALLY enjoys programming, and I'm hoping to glean from your years of experience here. At present, I'm studying PHP every chance I get, and have been for about 3 years, although I've never taken any formal classes. I'd love to some day be a programmer full time, and make a good career of it. My question to you is this: What do you consider to be the hallmarks or traits of a professional programmer? Mainly in the field of PHP, but other, more generalized qualifications are also more than welcome, as I think PHP is more of a hobbyist language and may not be the language of choice in the eyes of potential employers. Please correct me if I'm wrong. Above all, I don't want to wast time on something that isn't worth while. I'm currently feeling pretty confident in my knowledge of PHP as a language, and I know that I could build just about anything I need and have it "work", but I feel sorely lacking in design concepts and code structure. I can even write object oriented code, but in my personal opinion, that isn't worth a hill of beans if it isn't organized well. For this reason, I bought Matt Zandstra's book "PHP Objects, Patterns, and Practice" and have been reading that a little every day. Anyway, I'm starting to digress a little here, so back to the original question. What advice would you give to an aspiring programmer who wants to make an impact in this field? Also, on a side note, I've been working on a project with a friend of mine that would give a fairly good idea of where I'm at coding wise. I'm gonna give a link, I don't want anyone to feel as though I'm pushing or spamming here, so don't click it if you don't want to. But if you are interested on giving some feedback there as well, you can see the code on github. I'm known as The Craw there. https://github.com/PureChat/PureChat--Beta-/tree/

• FULL LIST Difference Edubuntu over Ubuntu

  - by Richard Kemp

  I have always used Edubuntu rather than Ubuntu because I have many children including home educated ones who casually use the education offerings. I appreciate many but not all of the extra offerings. I never got beyond 8.04.4 LTS, so am considering updating. I note now with Edubuntu 12.04 it is 2GB i.e.4 times bigger, even apparently using squashfs. I do now have to consider whether the extra resources are worth it in each computer in my household. I am sick of reading over and over again 'Edubuntu is Unbuntu with extras such as blah blah', and in a different place the same thing but with a different blah blah. I downloaded Edubuntu 12.04 and ran it 'live'. Can't say I got on at all with the Unity Interface (this can be changed when installed), but the apparent education stuff seemed quite small and pathetic, I am obviously not finding it. Is there anywhere a FULL LIST of what Edubuntu has pre-installed has over Ubuntu, so a sensible decision can be made whether to go for it, or just add packages that look relevant to me to Ubuntu. Is there truly no other difference between Unbuntu/Edubuntu but the extra educational packages? (I for example have no school server, but if I understood exactly what is involved, with the number of computers in the house, it may be worth creating one!) Please advise. Thank You.

• Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

  - by user12611315

  The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

• How do I make money from my FOSS while staying anonymous?

  - by user21007

  Let's say that: You have created a FOSS project that other people find useful, perhaps useful enough to donate to or pay for modifications to be done. It is a perfectly legitimate and innocuous software project. It has nothing to do with cryptography as munitions, p2p music, or anything likely to lead to a search warrant or being sued. You want your involvement to stay anonymous or pseudonymous. You would like to receive some money for your efforts, if people are willing. Is that possible, and if so, how could it be done? When I talk about anonymity, I realize that it is necessary to define the extent. I am not talking about Wikileaks style 20 layers of proxies worth of anonymity. I would expect a 3 letter agency to be able to identify the person easily. What is wanted is shielding from commercial competitors or random people, who would not be expected to be able to get the financial intermediary to divulge your details just by asking for them. Why would you want to stay anonymous? I can think of several valid reasons, maybe you operate a stealth mode startup and don't want to give your competitors clues as to the technology you are using. Maybe it is a project that has nothing to do with your daily job, is not developed there, but the company you work for has an unfair (and possibly unenforceable) policy stating that any coding you do is owned by them. Maybe you just value your privacy. For what it's worth, you intend to pay the relevant taxes in your country on any donations.

• Recommended storage scheme for home server? (LVM/JBOD/RAID 5...)

  - by j-g-faustus

  Are there any guidelines for which storage scheme(s) makes most sense for a multiple-disk home server? I am assuming a separate boot/OS disk (so bootability is not a concern, this is for data storage only) and 4-6 storage disks of 1-2 TB each, for a total storage capacity in the range 4-12 TB. The file system is ext4, I expect there will be only one big partition spanning all disks. As far as I can tell, the alternatives are individual disks pros: works with any combination of disk sizes; losing a disk loses only the data on that disk; no need for volume management. cons: data management is clumsy when logical units (like a "movies" folder) are larger than the capacity of any single drive. JBOD span pros: can merge disks of any size. cons: losing a disk loses all data on all disks LVM pros: can merge disks of any size; relatively simple to add and remove disks. cons: losing a disk loses all data on all disks RAID 0 pros: speed cons: losing one drive loses all data; disks must be same size RAID 5 pros: data survives losing one disk cons: gives up one disk worth of capacity; disks must be same size RAID 6 pros: data survives losing two disks cons: gives up two disks worth of capacity; disks must be same size I'm primarily considering either LVM or JBOD span simply because it will let me reuse older, smaller-capacity disks when I upgrade the system. The runner-up is RAID 0 for speed. I'm planning on having full backups to a separate system, so I expect the extra redundancy from RAID levels 5 or 6 won't be important. Is this a fair representation of the alternatives? Are there other considerations or alternatives I have missed? And what would you recommend?

• How to focus on one topic? [closed]

  - by Brian

  I have a huge problem while reading computer books. Every couple pages I'll end up googling something I want to learn more about, but then I'll find something on that page that I'll want to learn more about and google that (sometimes programming related, sometime hardware related). Normally after wasting around 3 hours going into different subjects I'll return to the original text only to repeat the process a few pages later. Any advice for sticking to one subject and learning that in-depth? I have tons of programming books I've read half-way through since I'll become interested in other languages/topics (not that I'm not interested in the books I've started). Also, what would be worth focusing on in depth? I've gone into Python in the most depth but for classes I'm learning Java and assembly (ARM and Motorola 68000). Also, I've taken a class on C++. Lately I've been spending most of my time learning about Linux instead of programming though. I'm not sure what would be worth focusing on the most to get a job. In other words, how can you focus on one topic and not let curiosity about everything else get in the way? Thanks in advance, Brian

• share distribution question

  - by facebook-100000781341887

  Hi, I just developed a facebook game(mifia like), but the graphic I make is not good, because it is reference with some existing photo, trace with AI, and coloring it. Therefore, I invite my friend to join me, he is a graphic designer, own a company with his friend (I know both of them), for the share, I expect at least 70% for me, and at most 30% for them (both of them want to join). Therefore, they give me a counter offer, 60% for me and 40% for them, of course, I feel their counter offer is unacceptable because they only build the image in part time, and all the other work just like coding, webhosting...etc, is what I do in full time. Why they said they worth 40% is that they will make a good graphic, they can provide a advertise channel(on local magazine), etc... Actually, I don't think the game need advertisement on local magazine because the game is not target for local... Please give me some comments on this issue(is the share fair? what is the importance of the image of the game, is it worth more than 30%), or can anyone share the experience on this. Thanks in advance.

• Computer Science graduate. Master or full-time job? [closed]

  - by Alex

  Possible Duplicate: Is a Master's worth it? I have just gotten my Bachelor's Degree in Computer Science and I have to make choice. Whether to continue with my full-time job I just got or put the job slightly in the background and concentrate on getting a Master's degree. I am currently working as an embedded C developer in a small company. The cool thing is that, because the team is quite small, my engineering ideas really play a part in the final product. Not to mention that I get to work on very different areas of embedded programming: device drivers and development of a Real Time OS. I am very enthusiastic about my job and what I do. On the other hand, in my country there isn't really a master's degree that focuses on embedded development so my gain from getting this degree will mainly in the field of general computer science knowledge. That being said, is it worth giving up all my spare time which I now use to study different areas of embedded devices and work mainly to get a degree rather than pure knowledge and experience in the field I want to work in?

• Making a Living Developing Games

  - by cable729

  I'm in my last year of high school, and I've been looking at colleges. I'm taking a C++ class at a local community college and I don't feel that it's worth it. I could have learned everything in that class in a week. This had me thinking, would a CS degree even be worth it? How much can it teach me if I can learn everything on my own? Even if I do need to learn more advanced subjects, many colleges put their material online AND I can buy a book. Will companies hire me if I don't have a CS degree? If I have a portfolio will I stand a chance? What kind of things are needed in the portfolio? I want to live doing what I love - programming. So I will do it. I'm just not sure that a CS degree will do anything to me. In addition, if there is a benefit to getting a CS degree, what places are the best?

• No root account

  - by user107744

  Okay, here's my problem. I was being an idiot and installed compiz-core on my Xubuntu 12.10. So there I was, trying to figure out how to fix my issue, and I did sudo xfwm4 --replace. Then I was unable to login. So I logging with guest, delete my old account, without deleting the home folder, of course, and I create a new account "michael2". Instead of creating a new home folder for it, I instead instructed the program to use my old home folder. Unfortunately, it completely erased the folder, along with over 150GB worth of downloads and about 200 hours worth of work (I work from home, so, yeah). And to top it all off, whenever I try to use the sudo command, I get the error michael2 is not in the sudoers file. This incident will be reported. I don't know how to fix this, nor can I login to root (I never set the root password, because I never had the need to login as root to do anything). Any help will be appreciated. Is there maybe a way that I can do system restore to restore my previous files and username? I need answers as soon as possible, because I'm literally losing money by the second (the entire work from home kinda thing).
