• Website running JavaScript setInterval starts to fail after ~1day

  - by Martin Clemens Bloch

  I wish I could be more specific here, but unfortunately this might be hard. I basically hope this is some "well"-known timeout or setup issue. We have a website running an (JS/html - ASP.net project) website overview on a screen at a factory. This screen has no keyboard so it should keep refreshing the page forever - years perhaps (though 1 week might be okay). (It is used by factory workers to see incoming transports etc.) This all works perfectly; the site continuously updates itself and gets the new correct data. Then, sometimes, in the morning this "overview" screen has no data and the workers have to manually refresh the site using the simple refresh button or F5 - which fixes everything. I have tried a few things trying to reproduce the error myself including: Cutting the internet connection and MANY other ways of making it timeout (breakpoints, stopping services etc.). Setting the refresh time of setInterval to 100ms and letting the site run 3-5 minutes. (normal timer is 1 minute) setInterval SHOULD run forever according to the internet searching I have done. Checked that "JavaScript frequency" has not been turned down in power saving settings. No matter what; the site resumes correct function WITHOUT a refresh as soon as I plug in the internet cable or whatever again - I can't reproduce the error. The website is dependent on a backend WCF service and project integration, but since the workers are fixing this with a simple refresh I am assuming this has not crashed. EDIT: The browser I tried to reproduce the error in was IE/win7. I will ask about the factory tomorrow, but I am guessing IE/win? also. Is setInterval in fact really infinite or is there something else wrong here? All help much appreciated. 0.5 bitcoin reward for solving answer ;)

• Keepalived for more than 20 virtual addresses

  - by cvaldemar

  I have set up keepalived on two Debian machines for high availability, but I've run into the maximum number of virtual IP's I can assign to my vrrp_instance. How would I go about configuring and failing over 20+ virtual IP's? This is the, very simple, setup: LB01: 10.200.85.1 LB02: 10.200.85.2 Virtual IPs: 10.200.85.100 - 10.200.85.200 Each machine is also running Apache (later Nginx) binding on the virtual IPs for SSL client certificate termination and proxying to backend webservers. The reason I need so many VIP's is the inability to use VirtualHost on HTTPS. This is my keepalived.conf: vrrp_script chk_apache2 { script "killall -0 apache2" interval 2 weight 2 } vrrp_instance VI_1 { interface eth0 state MASTER virtual_router_id 51 priority 101 virtual_ipaddress { 10.200.85.100 . . all the way to . 10.200.85.200 } An identical configuration is on the BACKUP machine, and it's working fine, but only up to the 20th IP. I have found a HOWTO discussing this problem. Basically, they suggest having just one VIP and routing all traffic "via" this one IP, and "all will be well". Is this a good approach? I'm running pfSense firewalls in front of the machines. Quote from the above link: ip route add $VNET/N via $VIP or route add $VNET netmask w.x.y.z gw $VIP Thanks in advance. EDIT: @David Schwartz said it would make sense to add a route, so I tried adding a static route to the pfSense firewall, but that didn't work as I expected it would. pfSense route: Interface: LAN Destination network: 10.200.85.200/32 (virtual IP) Gateway: 10.200.85.100 (floating virtual IP) Description: Route to VIP .100 I also made sure I had packet forwarding enabled on my hosts: $ cat /etc/sysctl.conf net.ipv4.ip_forward=1 net.ipv4.ip_nonlocal_bind=1 Am I doing this wrong? I also removed all VIPs from the keepalived.conf so it only fails over 10.200.85.100.

• Korn shell wraparound

  - by allenratcliff

  Okay, I'm sure this is simple but it is driving me nuts. I recently went to work on a program where I've had to step back in time a bit and use Redhat 9. When I'm typing on the command line from a standard xterm running Korn shell, when I reach the end of the line the screen slides to the right (cutting off the left side of my command) instead of wrapping the text around to a new line. This makes things difficult for me because I can't easily copy and paste from the previous command straight from the command line. I have to look at the history and paste the command from there. In case you're wondering, I do a lot of command-line awk scripts that cause the line to get quite long. Is there a way to force the command line to wrap instead of shifting visibility to the right side of the command I'm typing? I've poured through man page options with no luck. I'm running XFree86 4.2.99.903(174) and KSH 5.2.14. Thanks.

• Choosing a method for a webservice

  - by Wrikken

  I'm asked to set up a new webservice which should be easily usable in whatever language (php, .NET, Java, etc.) possible. Of course rolling my own can be done, accepting different content-types (xml / x-www-form-urlencoded (normal post) / json / etc.), but an existing method or mechanism would of course be prefered, cutting down time spent on development for the consumers of the service. The webservice does accept modifications / sets (it is not only simply data retrieval), but those will most likely be quite a lot less then gets (we estimate about 2.5% sets, 97.5 gets). The term webservice here indicates the protocol should go over HTTP, not being able to implement it totally client sided (javascript in the end-users browser etc.), as it needs specific user authentication. Both gets and sets are pretty light on the parameter count (usually 1 to 4). Methods like REST (which I'd prefer for only gets), XML-RPC & SOAP (might be a bit overkill, but has the advantage of explicitly defined methods and returns) are the usual suspects. What in your opinion / experience is the most widely 'spoken' and most easily implementable protocol in different languages (seen from the consumers' viewpoint) which could fullfill this need?

• What would you write in a Constitution (law book) for a programmers' country? [closed]

  - by Developer Art

  After we have got our great place to talk about professional matters and sozialize online - on SO, I believe the next logical step would be to found our own country! I invite you all to participate and bring together your available resources. We will buy an island, better even a group of islands so that we could establish states like .NET territories, Java land, Linux republic etc. We will build a society of programmers (girls - we need you too). To the organizational side, we're going to need some sort of a Constitution or a law book. I suggest we write it together. I make it a wiki as it should be a cooperative effort. I'll open the work. Section 1. Programmers' rights. Every citizen has a right to an Internet connection 24/7. Every citizen can freely choose the field of interest Section 2. Programmers' obligations. Every citizen must embrace the changing nature of the profession and constanly educate himself Section 3. Law enforcement. Code duplication when can be avoided is punished by limiting the bandwith speed to 64Kbit for a period of one week. Using ugly hacks instead of refactoring code is punished by cutting the Internet connection for a period of one month. Usage of technologies older than 5/10 years is punished by restricting the web access to the sites last updated 5/10 years ago for a period of one month. Please feel free to modify and extend the list. We'll need to have it ready before we proceed formally with the country foundation. A purchase fund will be established shortly. Everyone is invited to participate.

• How to get the dynamic generated content of an external ASP file using PhP?

  - by theCrius

  This is the situation: I've a PhP login page that check is an external ASP page has generated something (nickname). For example: i'm logged? So opening directly the asp page will display "nickname:thecrius" and nothing more. I'm not logged? So opening the ASP page will display nothing. Now i've to catch the "thecrius" string with a PhP page. Using file_get_contents only return me "nickname:", the "static" part of the asp page. What i'm doing wrong? Some codes: $aspSource = "http://www.domain.com/inc/whois.asp"; //ASP external $file = file_get_contents($aspSource); //get content of the asp page $start = strpos($file, "username:") + 9; //cutting off the "nickname:" $username = substr($file, $start); //get the username echo "URL-> $aspSource<br>Content-> $file<br>Start-> $start<br>Username-> $username<br>END"; But the result is only URL-> http://www.domain.com/inc/whois.asp Content-> username: Start-> 9 Username-> END Thanks in advance to anyone will help!

• Word wrap in multiline textbox after 35 characters

  - by Kanavi

  <asp:TextBox CssClass="txt" ID="TextBox1" runat="server" onkeyup="CountChars(this);" Rows="20" Columns="35" TextMode="MultiLine" Wrap="true"> </asp:TextBox> I need to implement word-wrapping in a multi-line textbox. I cannot allow users to write more then 35 chars a line. I am using the following code, which breaks at precisely the specified character on every line, cutting words in half. Can we fix this so that if there's not enough space left for a word on the current line, we move the whole word to the next line? function CountChars(ID) { var IntermediateText = ''; var FinalText = ''; var SubText = ''; var text = document.getElementById(ID.id).value; var lines = text.split("\n"); for (var i = 0; i < lines.length; i++) { IntermediateText = lines[i]; if (IntermediateText.length <= 50) { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } else { while (IntermediateText.length > 50) { SubText = IntermediateText.substring(0, 50); FinalText += SubText + "\n"; IntermediateText = IntermediateText.replace(SubText, ''); } if (IntermediateText != '') { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } } } document.getElementById(ID.id).value = FinalText; $('#' + ID.id).scrollTop($('#' + ID.id)[0].scrollHeight); } Edit - 1 I have to show total max 35 characters in line without specific word break and need to keep margin of two characters from the right. Again, the restriction should be for 35 characters but need space for total 37 (Just for the Visibility issue.)

• Reading a binary file in perl: Bad File Descriptor

  - by Magicked

  I'm trying to read a binary file 40 bytes at a time, then check to see if all those bytes are 0x00, and if so ignore them. If not, it will write them back out to another file (basically just cutting out large blocks of null bytes). This may not be the most efficient way to do this, but I'm not worried about that. However, right now I'm getting a "Bad File Descriptor" error and I cannot figure out why. my $comp = "\x00" * 40; my $byte_count = 0; my $infile = "/home/magicked/image1"; my $outfile = "/home/magicked/image1_short"; open IN, "<$infile"; open OUT, ">$outfile"; binmode IN; binmode OUT; my ($buf, $data, $n); while (read (IN, $buf, 40)) { ### Problem is here ### $boo = 1; for ($i = 0; $i < 40; $i++) { if ($comp[$i] != $buf[$i]) { $i = 40; print OUT $buf; $byte_count += 40; } } } die "Problems! $!\n" if $!; close OUT; close IN; I marked with a comment where it is breaking.

• Rails: Multiple "types" of one model through related models?

  - by neezer

  I have a User model in my app, which I would like to store basic user information, such as email address, first and last name, phone number, etc. I also have many different types of users in my system, including sales agents, clients, guests, etc. I would like to be able to use the same User model as a base for all the others, so that I don't have to include all the fields for all the related roles in one model, and can delegate as necessary (cutting down on duplicate database fields as well as providing easy mobility from changing one user of one type to another). So, what I'd like is this: User -- first name -- last name -- email --> is a "client", so ---- client field 1 ---- client field 2 ---- client field 3 User -- first name -- last name -- email --> is a "sales agent", so ---- sales agent field 1 ---- sales agent field 2 ---- sales agent field 3 and so on... In addition, when a new user signs up, I want that new user to automatically be assigned the role of "client" (I'm talking about database fields here, not authorization, though I hope to eventually include this logic in my user authorization as well). I have a multi-step signup wizard I'm trying to build with wizardly. The first step is easy, since I'm simply calling the fields included in the base User model (such as first_name and email), but the second step is trickier since it should be calling in fields from the associated model (like--per my example above--the model client with fields client_field_1 or client_field_2, as if those fields were part of User). Does that make sense? Let me know if that wasn't clear at all, and I'll try to explain it in a different way. Can anyone help me with this? How would I do this?

• What is the fastest way to find duplicates in multiple BIG txt files?

  - by user2950750

  I am really in deep water here and I need a lifeline. I have 10 txt files. Each file has up to 100.000.000 lines of data. Each line is simply a number representing something else. Numbers go up to 9 digits. I need to (somehow) scan these 10 files and find the numbers that appear in all 10 files. And here comes the tricky part. I have to do it in less than 2 seconds. I am not a developer, so I need an explanation for dummies. I have done enough research to learn that hash tables and map reduce might be something that I can make use of. But can it really be used to make it this fast, or do I need more advanced solutions? I have also been thinking about cutting up the files into smaller files. To that 1 file with 100.000.000 lines is transformed into 100 files with 1.000.000 lines. But I do not know what is best: 10 files with 100 million lines or 1000 files with 1 million lines? When I try to open the 100 million line file, it takes forever. So I think, maybe, it is just too big to be used. But I don't know if you can write code that will scan it without opening. Speed is the most important factor in this, and I need to know if it can be done as fast as I need it, or if I have to store my data in another way, for example, in a database like mysql or something. Thank you in advance to anybody that can give some good feedback.

• Resource placement (optimal strategy)

  - by blackened

  I know that this is not exactly the right place to ask this question, but maybe a wise guy comes across and has the solution. I'm trying to write a computer game and I need an algorithm to solve this question: The game is played between 2 players. Each side has 1.000 dollars. There are three "boxes" and each player writes down the amount of money he is going to place into those boxes. Then these amounts are compared. Whoever placed more money in a box scores 1 point (if draw half point each). Whoever scores more points wins his opponents 1.000 dollars. Example game: Player A: [500, 500, 0] Player B: [333, 333, 334] Player A wins because he won Box A and Box B (but lost Box C). Question: What is the optimal strategy to place the money? I have more questions to ask (algorithm related, not math related) but I need to know the answer to this one first. Update (1): After some more research I've learned that these type of problems/games are called Colonel Blotto Games. I did my best and found few (highly technical) documents on the subject. Cutting it short, the problem I have (as described above) is called simple Blotto Game (only three battlefields with symmetric resources). The difficult ones are the ones with, say, 10+ battle fields with non-symmetric resources. All the documents I've read say that the simple Blotto game is easy to solve. The thing is, none of them actually say what that "easy" solution is.

• Are Java developers really paid more than .Net developers? Also, should I just try and work with C?(

  - by Jon

  Ok, so I graduated about a year and a half ago. In college days I used to be really good (and keen) on C/C++. I've even done some multithreading and socket programming in C. Created networked GUI apps for linux using GTK etc.Now,I've been working since I graduated and well, let's say, I've been stereotyped with .net. That's all I have experience with in these years (Vb.net,asp.net,javascript). I'm pretty comfortable with all of the above and also SQL server.a)Cutting to the chase, I've begun to notice how .net jobs don't seem to pay all that well as Java. Jobs seeking similar number of yrs of experience offer almost twice for java developers. Does it mean I should consider switching?b)My heart still goes out for C. As a surrogate I've tried working with VC++ 6.0 (I know they aren't the same!). I've tried my hand with DDK,SDK,COM etc. Should I try finding jobs there or am I too inexperienced. Somehow, I can't find any openings for C. Where are they? Sometimes I get frustrated and feel that maybe I should just go for MS or something. Possibly that'll help me in landing with 'fatter paying jobs' in the field that I wish to work.

• Translate SQL to NHibernate Query

  - by Thad

  I have a SQL query that I would like to translate to nhibernate criteria, but I have not found a way to generate the MatchCount field. I tried adding it using a sqlprojection but I could not find a place to set the parameters. SELECT (CASE WHEN LEFT([FirstName], LEN(@Text0)) = @Text0 OR LEFT([FirstName], LEN(@Text1)) = @Text1 OR LEFT([FirstName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([LastName], LEN(@Text0)) = @Text0 OR LEFT([LastName], LEN(@Text1)) = @Text1 OR LEFT([LastName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([PreferredName], LEN(@Text0)) = @Text0 OR LEFT([PreferredName], LEN(@Text1)) = @Text1 OR LEFT([PreferredName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END) AS MatchCount , * FROM [client].[Individual] WHERE ( [FirstName] LIKE @Text0 + '%' OR [FirstName] LIKE @Text1 + '%' OR [FirstName] LIKE @Text2 + '%' OR [LastName] LIKE @Text0 + '%' OR [LastName] LIKE @Text1 + '%' OR [LastName] LIKE @Text2 + '%' OR [PreferredName] LIKE @Text0 + '%' OR [PreferredName] LIKE @Text1 + '%' OR [PreferredName] LIKE @Text2 + '%' ) ORDER BY (CASE WHEN LEFT([FirstName], LEN(@Text0)) = @Text0 OR LEFT([FirstName], LEN(@Text1)) = @Text1 OR LEFT([FirstName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([LastName], LEN(@Text0)) = @Text0 OR LEFT([LastName], LEN(@Text1)) = @Text1 OR LEFT([LastName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END + CASE WHEN LEFT([PreferredName], LEN(@Text0)) = @Text0 OR LEFT([PreferredName], LEN(@Text1)) = @Text1 OR LEFT([PreferredName], LEN(@Text2)) = @Text2 THEN 1 ELSE 0 END) DESC And yes, this is a ugly statement. Hate having a sql statement in the middle of everthing. Note: There is paging involved and I would prefer not returning all the data to the app server before cutting it down.

• Securing NTP: which method to use?

  - by Harry

  Can someone good at NTP configuration please share which method is the best/easiest to implement a secure, tamper-proof version of NTP? Here are some difficulties... I don't have the luxury of having my own stratum 0 time source, so must rely on external time servers. Should I read up on the AutoKey method or should I try to go the MD5 route? Based on what I know about symmetric cryptography, it seems that the MD5 method relies on a pre-agreed set of keys (symmetric cryptography) between the client and the server, and, so, is prone to man-in-the-middle attack. AutoKey, on the other hand, does not appear to work behind a NAT or a masquerading host. Is this still true, by the way? (This reference link is dated 2004, so I'm not sure what is the state of art today.) 4.1 Are public AutoKey-talking time servers available? I browsed through the NTP book by David Mills. The book looks excellent in a way (coming from the NTP creator after all), but the information therein is also overwhelming. I just need to first configure a secure version of NTP and then may be later worry about its architectural and engineering underpinnings. Can someone please wade me through these drowning NTP waters? Don't necessarily need a working config from you, just info on which NTP mode/config to try and may be also a public time server that supports that mode/config. Many thanks, /HS

• Button text loses allignment after clicking

  - by breathe0

  Strange things happen. I have a 4x4 button table layout, which is the following: <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@+id/cerca"> <TableRow android:layout_width = "fill_parent" android:layout_height = "wrap_content"> <Button android:id = "@+id/btn1" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_weight="1" android:text = "Scarica POI da server" android:onClick="downloadFromServer" /> <Button android:id = "@+id/btn2" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_weight="1" android:text = "Aggiungi POI" android:onClick="goCreatePOI" /> </TableRow> <TableRow android:layout_width = "fill_parent" android:layout_height = "wrap_content"> <Button android:id = "@+id/btn3" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_weight="1" android:text = "Rimuovi i POI del server" android:onClick="removeServerPOI" /> <Button android:id = "@+id/btn4" android:layout_width = "wrap_content" android:layout_height = "wrap_content" android:layout_weight="1" android:text = "Rimuovi i POI personali" android:onClick="removePersonalPOI" /> </TableRow> </TableLayout> This table layout is nested inside a relative layout, which is nested in a scrollview. Now, whenever i click on one of them, everytime the text inside the button change allignment: if before clicking was centered and displayed on two lines, after the click it loses its alignment and is displayed only in one row (cutting off some part of the text). Am I doing something wrong, or maybe it's a bug?

• Specific Shopping Cart Recommendations

  - by Dean J

  I'm trying to suggest a solution for a friend who owns an existing web shop. The current solution isn't cutting it. The new solution needs to have a few things that look like they're enterprise-only if I go with Magento, and $12k a year for a store with maybe $20k in stock just doesn't work. The site should have items, which have one or more categories. Each category may have a parent category. Items have MSRP, and a discount rate by supplier, brand, and sometimes additional discount by product. When a user buys something, it should automatically setup a shipping label with UPS or USPS, depending on user's choice, and build two invoices; one to go in the box, one to go into records. This is crucial; it's low profit per item, so it needs to minimize labor here. Need to be able to have sales (limited by time), discount codes/coupon codes. Ideally would have private sales and/or members-only rates as well. It needs a payment gateway; Paypal/GCheckout-only isn't going to fly. Must be able to accept Visa/MC. Suggestions? I'm debating just building this myself in Java or PHP, but wanted to point my friend to a reasonable-cost solution that already exists if I can. This all seems pretty straightforward to code, save working with the UPS/USPS/Visa/MC APIs, and doing CSS for it.

• Fitting Text into an Image

  - by Abs

  Hello all, I have a function which takes in a font (ttf or otf file) and generates an image of text in different fonts. The problem I have is trying to work out how I can make the text fit in the image regardless of the font-size, type of font, and amount of text. I have tried to make the image rectangle variable so that it contains the text of different fonts without cutting a bit of the text since the image is not long or wide enough. Here is the function that I currently have, I have tried using the number of characters to determine the width of the image, but in some cases for some fonts and sizes, it still gets cut off. function generate_image($save_path, $text, $font_path){ $length = strlen($text) * 15; // Create the image $im = imagecreatetruecolor($length, 40); $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $length, 40, $white); $font = $font_path; imagettftext($im, 30, 0, 0, 25, $black, $font, $text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thank you all for any help

• Saving a single entity instead of the entire context - revisited

  - by nite

  I’m looking for a way to have fine grained control over what is saved using Entity Framework, rather than the whole ObjectContext.SaveChanges(). My scenario is pretty straight forward, and I’m quite amazed not catered for in EF – pretty basic in NHibernate and all other data access paradigms I’ve seen. I’m generating a bunch of data (in a WPF UI) and allowing the user to fine tune what is proposed and choose what is actually committed to the database. For the proposed entities I’m: getting a bunch of reference entities (eg languages) via my objectcontext, creating the proposed entities and assigning these reference entities to them (as navigation properties), so by virtue of their relationship to the reference entities they’re implicitly added to the objectconext Trying to create & save individual entites based on the proposed entities. I figure this should be really simple & trivial but everything I’ve tried I’ve hit a brick wall, either I set up another objectcontext & add just the entity I need (it then tries to add the whole graph and fails as it’s on another objectcontext). I’ve tried MergeOptions = NoTracking on my reference entities to try to get the Attach/AddObject not to navigate through these to create a graph, no avail. I've removed the navigation properties from the reference entities. I've tried AcceptAllChanges, that works but pretty useless in practice as I do still want to track & save other entities. In a simple test, I can create 2 of my proposed entities, AddObject the one I want to save and then Detach the one I dont then call SaveChanges, this works but again not great in practice. Following are a few links to some of the nifty ideas which in the end don’t help in the end but illustrate the complexity of EF for something so simple. I’m really looking for a SaveSingle/SaveAtomic method, and think it’s a pretty reasonable & basic ask for any DAL, letalone a cutting edge ORM. http://stackoverflow.com/questions/1301460/saving-a-single-entity-instead-of-the-entire-context www.codeproject.com/KB/architecture/attachobjectgraph.aspx?fid=1534536&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=3071122&fr=1 bernhardelbl.spaces.live.com/blog/cns!DB54AE2C5D84DB78!238.entry

• Localisable Resources: how can (should one?!) wrap a UI layer source as a BL layer service?

  - by Ciel

  A service that returns localised strings could be wrapped in a service, so that it could be used both locally (eg in an MVC app) and remotely (eg possibly Silverlight). But...if sticking with the standard practice of creating resources in the UI assembly, that would in effect make a lower layer (BL/Services) have to have a ref on a higher layer (UI)...a definite no-no. And whereas a lot of AppWide resources (eg: AppName, OK, Cancel, etc.) could be defined in a Common cross-cutting assembly, and the BL/ResourceSerouce could ref and wrap those, that doesn't work in a a Modular App, where the Core app should have no binding to/knowledge of any Module. One solution could be to have each module, once mounted in mem, 'register' their Resource files with the service, who would then return it to the service (rather a long round trip, but at least consistent as a service, and potentially resources/images could be shared with other resources). Secondly, that may work in a web app...but not sure how that pattern could be extended to a Silverlight modular app (the round tripping becomes prohibitive). ie...what are best practices for allowing Resources to be to be defined by the UI designer, in a higher level, but served from the lower BL layer, as a Service? Or is there a better way of understanding/solving the problem?

• Avoiding resource (localizable string) duplication with String.Format

  - by Hrvoje Prgeša

  I'm working on a application (.NET, but not relevant) where there is large potential for resource/string duplication - most of these strings are simple like: Volume: 33 Volume: 33 (dB) Volume 33 dB Volume (dB) Command - Volume: 33 (dB) where X, Y and unit are the same. Should I define a new resource for each of the string or is it preferable to use String.Format to simplify some of these, eg.: String.Format("{0}: {1}", Resource.Volume, 33) String.Format("{0}: {1} {2}", Resource.Volume, 33, Resource.dB) Resource.Volume String.Format("{0} ({1})", 33, Resource.dB) String.Format("{0} ({1})", Resource.Volume, Resource.dB) String.Format("Command - {0}: {1} {2}", Resource.Volume, 33, Resource.dB) I would also define string formats like "{0}: {1}" in the resources so there would be a possibility of reordering words... I would not use this approach selectivly and not throughout the whole application.. And how about: String.Format("{0}: {1}", Volume, Resource.Muted_Volume) // = Volume: Muted Resource.Muted_Volume String.Format("{0}: {1} (by user {2})", Volume, Resource.Muted_Volume, "xy") // = Volume: Muted (by user xy) The advantage is cutting the number of resource by the factor of 4-5. Are there any hidden dangers of using this approach? Could someone give me an example (language) where this would not work correctly?

• How to remove empty tables from a MySQL backup file.

  - by user280708

  I have multiple large MySQL backup files all from different DBs and having different schemas. I want to load the backups into our EDW but I don't want to load the empty tables. Right now I'm cutting out the empty tables using AWK on the backup files, but I'm wondering if there's a better way to do this. If anyone is interested, this is my AWK script: EDIT: I noticed today that this script has some problems, please beware if you want to actually try to use it. Your output may be WRONG... I will post my changes as I make them. # File: remove_empty_tables.awk # Copyright (c) Northwestern University, 2010 # http://edw.northwestern.edu /^--$/ { i = 0; line[++i] = $0; getline if ($0 ~ /-- Definition/) { inserts = 0; while ($0 !~ / ALTER TABLE .* ENABLE KEYS /) { # If we already have an insert: if (inserts > 0) print else { # If we found an INSERT statement, the table is NOT empty: if ($0 ~ /^INSERT /) { ++inserts # Dump the lines before the INSERT and then the INSERT: for (j = 1; j <= i; ++j) print line[j] i = 0 print $0 } # Otherwise we may yet find an insert, so save the line: else line[++i] = $0 } getline # go to the next line } line[++i] = $0; getline line[++i] = $0; getline if (inserts > 0) { for (j = 1; j <= i; ++j) print line[j] print $0 } next } else { print "--" } } { print }
