  • Secure Yourself by Using Two-Step Verification on These 16 Web Services

    - by Chris Hoffman
    Two-factor authentication, also known as 2-step verification, provides additional security for your online accounts. Even if someone discovers your password, they’ll need a special one-time code to log in after you enable two-factor authentication on these services. Notably absent from this list are banks and other financial institutions. It’s a shame that you can use two-factor authentication to protect your in-game currency in an MMORPG, but not the real money in your bank account.

  • Sell Yourself! Presentation

    - by Mike C
    Thanks to everyone who attended my "Sell Yourself!" presentation at SQLSaturday #61 in Washington, D.C., and thanks to NOVA SQL for setting up the event!

This deck includes a new section on recruiters and a little more information on the resume. BTW, if you're rewriting your resume I highly recommend the book Elements of Resume Style by S. Bennett.

  • How do you stop yourself from programming?

    - by dan
    Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

  • Trouble with go tour crawler exercise

    - by David Mason
    I'm going through the go tour and I feel like I have a pretty good understanding of the language except for concurrency. On slide 71 there is an exercise that asks the reader to parallelize a web crawler (and to make it not cover repeats but I haven't gotten there yet.) Here is what I have so far: func Crawl(url string, depth int, fetcher Fetcher, ch chan string) { if depth <= 0 { return } body, urls, err := fetcher.Fetch(url) if err != nil { ch <- fmt.Sprintln(err) return } ch <- fmt.Sprintf("found: %s %q\n", url, body) for _, u := range urls { go Crawl(u, depth-1, fetcher, ch) } } func main() { ch := make(chan string, 100) go Crawl("http://golang.org/", 4, fetcher, ch) for i := range ch { fmt.Println(i) } } The issue I have is where to put the close(ch) call. If I put a defer close(ch) somewhere in the Crawl method, then I end up writing to a closed channel in one of the spawned goroutines, since the method will finish execution before the spawned goroutines do. If I omit the call to close(ch), as is shown in my example code, the program deadlocks after all the goroutines finish executing but the main thread is still waiting on the channel in the for loop since the channel was never closed.

  • How to check function parameters in Go

    - by deamon
    Guava Preconditions allows to check method parameters in Java easily. public void doUsefulThings(Something s, int x, int position) { checkNotNull(s); checkArgument(x >= 0, "Argument was %s but expected nonnegative", x); checkElementIndex(position, someList.size()); // ... } These check methods raise exceptions if the conditions are not met. Go has no exceptions but indicates errors with return values. So I wonder how an idiomatic Go version of the above code would look like.

  • What are the advantages of learning Go?

    - by Pangea
    What is so unique about Go? Over the 11 years of my career I've learnt Pascal, C, C++, COBOL and then Java. I always felt that going from C to C++ to Java was a incremental and value added progression. Now I see a proliferation of functional programming languages and I understand the benefit of learning few of them (like actors in scala etc). Now I was going through the Go programming language and was wondering why would I want to learn this? Is this going to simplify how I have been writing the code? What are its use cases? How can I make a case to promote it in my team? What is the next programming language that a Java team that builds business applications like us can benefit from? Appreciate your comments on this.

  • Go, AppEngine: How to structure templates for application

    - by laslowh
    How are people handling the use of templates in their Go-based AppEngine applications? Specifically, I'm looking for a project structure that affords the following: Hierarchical (directory) structure of templates and partial templates Allow me to use HTML tools/editors on my templates (embedding template text in xxx.go files makes this difficult) Automatic reload of template text when on dev server Potential stumbling blocks are: template.ParseGlob() will not traverse recursively. For performance reasons it has been recommended not to upload your templates as raw text files (because those text files reside on different servers than executing code). Please note that I am not looking for a tutorial/examples of the use of the template package. This is more of an app structure question. That being said, if you have code that solves the above problems, I would love to see it. Thanks in advance.

  • Motivating yourself to actually write the code after you've designed something

    - by dpb
    Does it happen only to me or is this familiar to you too? It's like this: You have to create something; a module, a feature, an entire application... whatever. It is something interesting that you have never done before, it is challenging. So you start to think how you are going to do it. You draw some sketches. You write some prototypes to test your ideas. You are putting different pieces together to get the complete view. You finally end up with a design that you like, something that is simple, clear to everybody, easy maintainable... you name it. You covered every base, you thought of everything. You know that you are going to have this class and that file and that database schema. Configure this here, adapt this other thingy there etc. But now, after everything is settled, you have to sit down and actually write the code for it. And is not challenging anymore.... Been there, done that! Writing the code now is just "formalities" and makes it look like re-iterating what you've just finished. At my previous job I sometimes got away with it because someone else did the coding based on my specifications, but at my new gig I'm in charge of the entire process so I have to do this too ('cause I get payed to do it). But I have a pet project I'm working on at home, after work and there is just me and no one is paying me to do it. I do the creative work and then when time comes to write it down I just don't feel like it (lets browse the web a little, see what's new on P.SE, on SO etc). I just want to move to the next challenging thing, and then to the next, and the next... Does this happen to you too? How do you deal with it? How do you convince yourself to go in and write the freaking code? I'll take any answer.

  • Help yourself . if you like

    - by rachelp
    At Red Gate we enjoy talking to our customers. Really! If you've read recent blog posts by members of some of our customer-facing teams, you'll have spotted the pleasure they take in their work. In case you missed those posts, here they are: From our Finance team: Finance: Friends, not foes! From our reception desk: The Front line of Communication However, we recognise that sometimes our customers would like to be able to solve their problems or answer their questions without talking to us - they're in a hurry, it's outside office hours . or perhaps they just prefer not to pick up the phone and call.   Self-service customer care So we've begun a programme of work to enable more self-service; whether it's finding the answer to a "how do i.?" question or getting access to a record of what product licenses they own, we want to make it much easier for our customers to get hold of this information for themselves. If they want to.   Phase 1: make it easier to find information We decided to start by tackling findability. We've got loads of useful information on our website, but it's sometimes difficult to find, so we've been working on improving our site search. Step 1 has been to replace the search engine, clean up the search UI, and make it consistent across the site. We're nearly there! The idea is that if we improve the site search it will be easier - and much more pleasant - for people to find the information they need. The new search will go live some time in April, and then we'll be gathering feedback, looking at web analytics (more about this in an earlier article), and working out what improvements we still need to make. We'd love to hear what you think, so do give your feedback or drop us a line. Or pick up the phone and call, if you like.   What do you think? While I've got your attention, I'd love to hear what people think about self-service customer care. Do you like to call, email, live chat . or do you prefer to dig around and find out answers yourself? Who's getting it right: what self-service sites do you like? p.s. Watch this space for news of phase 2.

  • Go - How to read/write to file?

    - by Seth Hoenig
    I've been trying to learn Go / Golang on my own, but I've been stumped on trying read and write to ordinary files. I can get as far as: inFile,_ := os.Open(INFILE,0,0); but actually getting the content of the file doesn't make sense, since the read function takes a []byte as a parameter?? func (file *File) Read(b []byte) (n int, err Error)

  • Help me choose between Go and Io

    - by Robert Smith
    During the following months I'll have some spare time so I thought of picking up a new programming language.I've been reading some articles about Go and Io and both of them look interesting and very promising so I'm stuck making a decision about which one to pick up next. I'm mainly interested in distributed systems and concurrency. Any help is greatly appreciated. Thanks.

  • How to pass arguments to Go program?

    - by oraz
    I can't see arguments for main() in package main. How to pass arguments from command line in Go? A complete program, possibly created by linking multiple packages, must have one package called main, with a function func main() { ... } defined. The function main.main() takes no arguments and returns no value.

  • Go - Data types for validation

    - by nevalu
    How to create a new data type for Go which to can check/validate its schema when is created a new variable (of that type)? By example, to validate if a string has 20 characters, I tried: // Format: 2006-01-12T06:06:06Z func date(str string) { if len(str) != 20 { fmt.Println("error") } } var Date = date() type Account struct { domain string username string created Date } but it fails because Date is not a type.

  • Go Channels in Ruby

    - by Julius Eckert
    In the Go programming language, you can send Messages around using a construct called "Channels". http://golang.org/doc/effective_go.html#channels I would love to use something like that in Ruby, especially for IPC. Pseudocode of what I want: channel = Channel.new fork do 3.times{ channel.send("foo ") } exit! end Thread.new do 3.times{ channel.send("bar ") } end loop do print channel.recv end # ~> bar foo foo bar bar foo Is there any construct, library or equivalent for Ruby which works like that ? If not: What is the best way to build such an abstraction?

  • Porting Java app to Go - any advice?

    - by Devrim
    We want to rewrite kodingen.com backend with Go which currently is Java, running as daemon using jsvc. I have never touched any C in my life, am only experienced in Java so I don't know if this is something that I should even start. However, task is pretty simple read shell commands from mysql database queue and execute them in parallel save each shell output to the database that's it. So these simple requirements gives me hope that I can start using this wonderful language. What would you advise?

  • Unix Sockets in Go

    - by marketer
    I'm trying to make a simple echo client and server that uses Unix sockets. In this example, the server can receive data from the client, but it can't send the data back. If I use tcp connections instead, it works great: Server package main import "net" import "fmt" func echoServer(c net.Conn) { for { buf := make([]byte, 512) nr, err := c.Read(buf) if err != nil { return } data := buf[0:nr] fmt.Printf("Received: %v", string(data)) _, err = c.Write(data) if err != nil { panic("Write: " + err.String()) } } } func main() { l, err := net.Listen("unix", "/tmp/echo.sock") if err != nil { println("listen error", err.String()) return } for { fd, err := l.Accept() if err != nil { println("accept error", err.String()) return } go echoServer(fd) } } Client package main import "net" import "time" func main() { c,err := net.Dial("unix","", "/tmp/echo.sock") if err != nil { panic(err.String()) } for { _,err := c.Write([]byte("hi\n")) if err != nil { println(err.String()) } time.Sleep(1e9) } }
