• Should I limit my type name suffix vocabulary when using OOP?

  - by Den

  My co-workers tend to think that it is better to limit non-domain type suffixes to a small fixed set of OOP-pattern inspired words, e.g.: *Service *Repository *Factory *Manager *Provider I believe there is no reason to not extend that set with more names, e.g. (some "translation" to the previous vocabulary is given in brackets): *Distributor (= *DistributionManager or *SendingService) *Generator *Browser (= *ReadonlyRepositoryService) *Processor *Manipulator (= *StateMachineManager) *Enricher (= *EnrichmentService) (*) denotes some domain word, e.g. "Order", "Student", "Item" etc. The domain is probably not complex enough to use specialized approaches such as DDD which could drive the naming.

• is there a way to prespecify to overwrite files with same name?

  - by Celeritas

  Connections to network drives are ridiculously slow (e.g. 15kb/sec on really good days) and when I'm copying files I leave my desk. My problem is when there is a file with the same name to be overwritten, is there a way to specify in advanced to overwrite files? I know it has the option "do same for next x conflicts" but that doesn't popup until (in some cases) a long time after the files start copying. See my dilemma? Example: copying 500 files, estimated time 2 hours, I leave, after 10 minutes message comes up about file with same name and asks if it should overwrite (in this time copying stalls), I come back 30 minutes latter to find only the files in the 10 minutes copied. Out of curiosity how could the network speed be so bad? I asked the boss and he said because it gets routed around a lot and is just bad :(

• Is there a specific name for the ".\" (dot-slash) shorthand used to log onto a Windows machine?

  - by HopelessN00b

  I guess the title just about says it all. And yes, .\, not that obsolete \. thing. :) For those who don't know, .\ is a shorthand way of saying "this computer" in Windows at a logon screen, which comes in very handy when you don't know or care about the local computer name but need to authenticate against it anyway, such as through RDP or scripting against a set of shared local users and passwords or even locally, if you're unlucky enough to have to physically go to a machine. Anyway, does this have an actual name, and if so, what is it? I feel kind of stupid saying the dot-slash thing, which is how I've been referring to this.

• How to transform a csv to combine matching rows?

  - by Christian Wolf

  I have a CSV file with some transaction data. Let's say date, volume, price and direction (sell/buy). Additionally there is a ID for each transaction and on each closing transaction (the newer one) there is a reference to the corresponding transaction. Classical database referencing. Now I want to do some statistics and draw some plots. This could be done via Octave, LaTeX/TikZ, Gnuplot or whatever. To do this I need both buy and sell price in one row. My thought was to preprocess the CSV to get another CSV containing the needed information and then to do the statistics. In the end I'd like to have a solution based on scripts and not on a spreadsheet as data might change often (exported from online DB). My actual solution (see http://paste.ubuntu.com/6262822/ ) is a bash script that parses the CSV line by line and checks if there exists a corresponding transaction. If found, a new row is written to the destination CSV. If not a warning is printed. The bad news: For each row in the source file I have to read the whole file a few times. This causes long running times of 10sec for 300 lines. As the line number might rise soon (10k lines), this is not perfect. I am aware, that there are many shells to be opened in the script which might cause the performance problems. Now my questions: Is bash/awk/sed/.... a good way to do things? Should I first import all data into a "real" local database to use SQL? Is there an easy way to achieve the desired results?

• unable to send mail from postfix on Ubuntu 12.04

  - by gilmad

  I'm trying to send an email through Google from my localhost. (via PHP5.3) But Google keeps on blocking my requests. I tried to follow the solutions given to a few similar questions, but for some reason they do not work.

• SEO penalty for "duplicate" content when a site's also accessible via another domain name?

  - by tog22

  While testing searches for keywords on my site, I notice that a mirror of it at http://a8.8d.344a.static.theplanet.com/ sometimes appears at the top result rather than my primary domain. It looks like this is an alternative address for my server. Will the presence of identical content at this domain and at my primary domain result in a Google penalty? If so, what can I do about it? Thanks for any help...

• Is there a name for the Builder Pattern where the Builder is implemented via interfaces so certain parameters are required?

  - by Zipper

  So we implemented the builder pattern for most of our domain to help in understandability of what actually being passed to a constructor, and for the normal advantages that a builder gives. The one twist was that we exposed the builder through interfaces so we could chain required functions and unrequired functions to make sure that the correct parameters were passed. I was curious if there was an existing pattern like this. Example below: public class Foo { private int someThing; private int someThing2; private DateTime someThing3; private Foo(Builder builder) { this.someThing = builder.someThing; this.someThing2 = builder.someThing2; this.someThing3 = builder.someThing3; } public static RequiredSomething getBuilder() { return new Builder(); } public interface RequiredSomething { public RequiredDateTime withSomething (int value); } public interface RequiredDateTime { public OptionalParamters withDateTime (DateTime value); } public interface OptionalParamters { public OptionalParamters withSeomthing2 (int value); public Foo Build ();} public static class Builder implements RequiredSomething, RequiredDateTime, OptionalParamters { private int someThing; private int someThing2; private DateTime someThing3; public RequiredDateTime withSomething (int value) {someThing = value; return this;} public OptionalParamters withDateTime (int value) {someThing = value; return this;} public OptionalParamters withSeomthing2 (int value) {someThing = value; return this;} public Foo build(){return new Foo(this);} } } Example of how it's called: Foo foo = Foo.getBuilder().withSomething(1).withDateTime(DateTime.now()).build(); Foo foo2 = Foo.getBuilder().withSomething(1).withDateTime(DateTime.now()).withSomething2(3).build();

• How do I get the machine name from an IP via Multicast DNS?

  - by Adam

  I have a list of IP addresses on a network, and most of them support multicast DNS. I'd like to be able to resolve the server name instead of just having the IP address. ping computer.local 64 bytes from 192.168.0.52: icmp_seq=1 ttl=64 time=5.510 ms 64 bytes from 192.168.0.52: icmp_seq=2 ttl=64 time=5.396 ms 64 bytes from 192.168.0.52: icmp_seq=3 ttl=64 time=5.273 ms Works, but I'd like to be able to determine that name from the IP. Also the devices don't necessarily broadcast any services, but definitely do support mDNS broadcast. So looking through services won't work.

• Rename file in XP, only select file name, but show file extension.

  - by RasmusWriedtLarsen

  So if I have a file called: test.txt and I want to rename it, there are two options (depending on the Show already known file extension option): 1) ON: it selects everything (test.txt), meaning I have to manually select "test" and replace it with the new filename. (which is irritating) 2) OFF: Only "test" is editable (and visible). Problem is that I frequently need to change the file extension of a file, but if the option is turned on, it's a pain to change the file name. I know that in Win7 it does something smart: It only selects the file name when you press rename[F2], but also lets you edit the file extension. Is there a way to accomplish this?

• I bought a domain name at GoDaddy and hosting at Dreamhost but the first doesn't work!

  - by janooChen

  I added the Dreamhost's nameservers like 12 hours ago to: I entered to the following panel: Nameservers -> Set Nameservers (I have specific nameservers for my domains) and added Dreamhost's nameservers liek this: Nameserver 1: NS1.DREAMHOST.COM Nameserver 2: NS2.DREAMHOST.COM Nameserver 3: NS3.DREAMHOST.COM So now in the admin panel I see this: Nameservers Nameservers: (Last Update 2/10/2011) NS1.DREAMHOST.COM NS2.DREAMHOST.COM NS3.DREAMHOST.COM But I get this when I run the analysis tools: Attention Required! There are critical issues Accessing Your Web Site Accessing Your Web Site Properly configuring your domain name and hosting account ensures that visitors can access your site. Did I do something wrong or I have to wait 24 to 48 hours? (Dreamhost does display my page because I can access the other domain name I bought together with the hosting) (By the way, if everyone uses the same nameserver, how will go GoDaddy know which is the hosting space that I purchased among all others)? Thanks in advance.

• dedicated domain name VS just folders under a single domain?

  - by Ben Keating

  I run WordPress-Multisite for several sites. Each of these sites resolve under a single domain, e.g. example.com/foo/, example.com/bar/. I also have domain names for these e.g. foo.com, bar.com. which are currently redirects, so if a user hits foo.com, they are redirected (301) to example.com/foo/. My question is, should it be the other way around? should I use the dedicated domain names directly? What are the pros/cons of putting multiple sites under a single domain vs their own dedicated domains. I guess im asking with SEO and findability in mind.

• Am I missing something about these considerations about Leaderboard's database's schema?

  - by misiMe

  I just finished to develop a mobile game, now I want to implement an online leaerboard using mysql. I'm wondering about the database's schema, I thought about some possibilities: (I didn't got in detail with syntax because my question is just about the logic of it) Name: string; Score: integer I thought to ask the name just the first time. If, in the future, you will modify that, it will call just an update to the name associated with your id. Leaderboard(ID, Name, Score) ID: integer autoincrement, PrimaryKey With this kind of idea maybe the db will grow fast because if you choose everytime a different name for the score, it will add a new entry. Leaderboard(PhoneId, Name, Score) Here PhoneId will be the unique identifier of the phone, PrimaryKey. A con of this choice is that if you want to play with your friends' phone, you can't put a different name for the score. Leaderboard(Name, Score) Here Name is PrimaryKey. With that, if you enter a name that already exists, you will be prompted to choose another one. Do you agree with this considerations? What will you do? Am I missing something?

• How to see the full file name on the Lubuntu Desktop?

  - by vasa1

  If I have a file with several characters in it, only a certain number of initial characters is displayed on the Lubuntu desktop and Xfce desktops. For example, I have a file titled, "interesting-links-on-default-browsers". It shows as "interesting-links-on-def..." with both DEs. However, single-clicking on the file in Xfce shows the full title but the truncated title remains in Lubuntu. It's not a big deal, but if it's just a matter of setting something somewhere to get the full title visible on single-click, I'd be grateful for pointers.

• Can't change folder background

  - by newcomer

  I tried to change via dragging from the Backgrounds and Emblems window, but the icon just goes back to that window rather than changing the folder background.However, I can change the task bar by this drag-n-drop.

• Create and manage child name servers (glue records) within my domain?

  - by basilmir

  Preface I use a top level domain provider that only allows me to add "normal" third-party name servers (a list where i can add "ns1.hostingcompany.com" type entries... nothing else) AND "child name servers" which i can later attach to my parent account ( ns1.myowndomain.com and an ip address). They do not provide other means of linking up. I want to host my own server and dns, even with just one name server (at first). My setup: Airport Extreme - get's a static ip address from my ISP Mac Mini Server - sits behind the Airport and get's a 10.0.1.2 My problem is that i can't seem to configure DNS correctly. I added a "child nameserver" with my airport's external static ip address at the top level provider, so to my understanding i should have all DNS traffic redirected to my Airport. I've opened port 53 UDP to let the traffic in. Now, what i don't get is this. My Mini Server is sitting on a 10.0.1.2 address and i have setup dns correctly, with an A record to point and resolve my server AND a reverse lookup to that 10.0.1.2. So it's ok for "internal stuff". Here is the clicker... How, when a request comes from the exterior for a reverse lookup, does the server "know" ... well look i have everything in 10.0.1.2 but the guy outside needs something from my real address. I can't begin to describe the MX record bonanza... How do i set this "right"? Do i "need" my Mini Server to sit on the external address directly (i can see how this could be the preferred solution, being close to a "real" server i have in my mind). If not... do i need a PTR record on the 10.0.1.2 server but with the external address in there? My dream: I will extend this "setup" with multiple Mini's in different cities where i work. I want a distributed something (Xgrid comes to mind). PS. Be gentle, i've read 2 books and the subject, and bought both the Lynda Essentials and DNS and Networking to boot, still i'm far from being on top of things.

• What is a descriptive name for a web service that responds with plain text?

  - by Rich Shealer

  I'm looking for the proper name for a web service that responds with text as opposed to XML. As an example this "cardServer" service will return 5 cards for a poker hand. http://hostname:8080/cardServer/deal/Game=Poker&Qty=5 The result could look like this: Card1=Ad Card2=Kc Card3=Ts Card4=5d Card5=3d The real world example is not as trivial, but the concept is the same. Parameters if any are passed as POST variables. We currently parse the response into a string list and use the values. The process works just fine. What I'm wondering if this service method has a name that has easier tools to deal with the responses and therefore did we reinvent the wheel? For the record the service was provided and maintained by a customer.

• How to direct a Network Solutions domain name to an html website hosted on Google Drive? [on hold]

  - by Air Conditioner

  To begin with, I'd wanted to take advantage of HTML, CSS, and so on to build a website that looks and works just as I'd like it to. I took a look around on how I could make that work, and I soon saw a lifehacker article showing that its possible to host website files on google drive. I then made sure that the folder containing the files was shared publicly throughout the web, and I now have a working 'google drive hosted' domain for the website. However, I did want to have the custom domain, and so I registered one with network solutions. So now, I'm curious on how I should direct my Network Solutions domain to the index.html I'm hosting on google drive. Would anyone have an Idea?

• Why is this MySQL FULLTEXT query returning 0 rows when matching rows are present?

  - by Don MacAskill

  I have a MySQL table with 200M rows which has a FULLTEXT index on two columns (Title,Body). When I do a simple FULLTEXT query in the default NATURAL LANGUAGE mode for some popular results (they'd return 2M+ rows), I'm getting zero rows back: SELECT COUNT(*) FROM itemsearch WHERE MATCH (Title, Body) AGAINST ('fubar'); But when I do a FULLTEXT query in BOOLEAN mode, I can see the rows in question do exist (I get 2M+ back, depending): SELECT COUNT(*) FROM itemsearch WHERE MATCH (Title, Body) AGAINST ('+fubar' IN BOOLEAN MODE); I have some queries which return ~500K rows which are working fine in either mode, so if it's result size related, it seems to crop up somewhere between 500K and a little north of 2M. I've tried playing with the various buffer size variables, to no avail. It's clearly not the 50% threshold, since we're not getting 100M rows back for any result. Any ideas?

• What filesystem comes closest to matching NTFS for support of ACLs, and highly-granular permissioning?

  - by warren

  It seems that most other filesystems handle the basic *nix permissions (ugo±rwx), with maybe an addition here or there. Or can be "made" to handle ACLs through the use of other tools on top of the system. On the wikipedia pages about filesystems (http://en.wikipedia.org/wiki/List%5Fof%5Ffile%5Fsystems & http://en.wikipedia.org/wiki/Comparison%5Fof%5Ffile%5Fsystems), it appears that while some do support extended meta-data, none support natively the level of permissioning that NTFS does. Am I wrong in this understanding?

• In dependency injection, is there a simple name for the counterpart of the injected object?

  - by kostja

  In tutorials and books, I have never seen a single word describing the object that the injected object is injected into. Instead, other terms are used, like "injection point" which don't denote the object containing the injected object. And nothing I can think of sounds right, except maybe "injection target" - but I have never read it anywhere. Is there a single word or a simple expression for it, or is it like the "He-Who-Must-Not-Be-Named" from a recent fantasy book series?

• Windows 7 search for files with special characters in name.

  - by Luke

  I have a rather large source code repository on my machine; it is not indexed by Windows Search. I am trying to find some oddly-named generated files of the form .#name.extension.version where name and extension are normal names and extensions and version is a numeric value (e.g. something like 1.186). On Windows XP I could find these files by searching for .#*; on Windows 7 that just returns every single file and directory. So my question is this: is it possible to find files named like that using the built-in Windows 7 search functionality? I did find this question which is very similar, but the answer doesn't work for me; it seems like any special character I put in the query is either ignored or treated as a wildcard, and as a result it matches every single file and directory. Is there perhaps some registry value I can set to make the search-by-filename feature work with special characters?
