  • People != Resources

    - by eddraper
    Ken Tabor’s blog post “They Are not Resources – We Are People” struck a chord with me.  I distinctly remember hearing the term “resources” within the context of “people” for the first time back in the late 90’s.  I was in a meeting at Compaq and a manager had been faced with some new scope for an IT project he was managing.  His response was that he needed more “resources” in order to get the job done.  As I knew the timeline for the project was fixed and the process for acquiring additional funding would almost certainly extend beyond his expected delivery date, I wondered what he meant.  After the meeting, I asked him what he meant… his response was that he needed some more “bodies” to get the job done.  For a minute, my mind whirred… why is it so difficult to simply say “people?”  This particular manager was neither a bad person nor a bad manager… quite the contrary.  I respected him quite a bit and still do.  Over time, I began to notice that he was what could be termed an “early adopter” of many “Business speak” terms – such as “sooner rather than later,” “thrown a curve,” “boil the ocean” etcetera.  Over time, I’ve discovered that much of this lexicon can actually be useful, though cliché and overused.  For example, “Boil the ocean” does serve a useful purpose in distilling a lot of verbiage and meaning into three simple words that paint a clear mental picture.  The term “resources” would serve a similar purpose if it were applied to the concept of time, funding, or people.  The problem is that this never happened.  “Resources”, “bodies”, “ICs” (individual contributors)… this is what “people” have become in the IT business world.  Why?  We’re talking about simple word choices here.  Why have human beings been deliberately dehumanized and abstracted in this manner? What useful purpose does it serve other than to demean and denigrate?

  • Test-Driven Development with plain C: manage multiple modules

    - by Angelo
    I am new to test-driven development, but I'm loving it. There is, however, a main problem that prevents me from using it effectively. I work for embedded medical applications, plain C, with safety issues. Suppose you have module A that has a function A_function() that I want to test. This function call a function B_function, implemented in module B. I want to decouple the module so, as James Grenning teaches, I create a Mock module B that implements a mock version of B_function. However the day comes when I have to implement module B with the real version of B_function. Of course the two B_function can not live in the same executable, so I don't know how to have a unique "launcher" to test both modules. James Grenning way out is to replace, in module A, the call to B_function with a function pointer that can have the value of the mock or the real function according to the need. However I work in a team, and I can not justify this decision that would make no sense if it were not for the test, and no one asked me explicitly to use test-driven approach. Maybe the only way out is to generate different a executable for each module. Any smarter solution? Thank you

  • Life Is Full Of Changes (Part 1)

    - by Brian Jackett
    Today will be my last day with Sogeti.  I’ve been with Sogeti USA for just over 4 years.  In that time I’ve gotten to work on some great projects, develop relationships with some brilliant and passionate people, participate in the .Net developer and SharePoint communities, and grow my skills in a number of areas I’m passionate about.     As with all good things they must come to an end though.  I’ve accepted a position with another company and will provide more details once the transition has completed.  This decision was a difficult one to make but it provides a great career opportunity on many levels.  As much as my new schedule allows I plan to continue participating in local user groups, speaking at conferences, and blogging.     Speaking of which, you may have noticed my reduced blogging activity in the past few months.  In addition to a career change I’m also in the process of moving to a new residence (only a few miles from my current residence, so I’ll still be in Columbus.)  Searching for a new place, filling out paperwork, and all of the other work associated with this move has taken away a good chunk of the time I used to devote to blogging.  Once everything gets settled out with the move and job change I’ll re-evaluate how much time I can devote to blogging.     A big thanks to Sogeti and everyone who has been so supportive over my time with them.  It’s hard to move on, but I am excited for the prospects that the future will bring.         -Frog Out

  • Beginners guide to developing optimization software

    - by Florenc
    I am novice in "serious" programming i.e. applications that deal with real-life applications and software projects that go beyond school assignments. My interests include optimization, operations research, algorithms and lately i discovered how much I do like software design/development/engineering. I have already developed some simple desktop applications for some "famous" problems like TSP using heuristc approaches, a VRP solver (in progress) and so on. While developing this kind of software I actually used basic concepts taught at school such as object-orientation analysis and design. But, I found these courses rather elementary and quite boring (for my expectations). So I decided to go a little further and start developing "real" software (and this is where I realized how important and interesting software engineering/design is.) Now, here's my issue: I can not find a "study guide" for developing software of this kind. Currently, there are numerous resources out there (books, websites, tutorials) in designing and developing complex IS, web applications, smartphone apps but I can't find a book for example entitled "optimization software development". Definetly, someone could claim that "design patterns apply to software in general" but that's not my point. My point is that I could simply use my imagination for "simple" implementations, but what happens, when my imagination can not go further? In other words I'm looking for a guide/path to bridge the gap between: Mathematics-Algorithm Design-Software Engineering-Optimization-Software development

  • Photoshop alternative with same keyboard shorcuts

    - by user292254
    tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

  • Static pages for large photo album

    - by Phil P
    I'm looking for advice on software for managing a largish photo album for a website. 2000+ pictures, one-time drop (probably). I normally use MarginalHack's album, which does what I want: pre-generate thumbnails and HTML for the pictures, so I can serve without needing a dynamic run-time, so there's less attack surface to worry about. However, it doesn't handle pagination or the like, so it's unwieldy for this case. This is a one-time drop for pictures from a wedding, with a shared usercode/password for distribution to the guests; I don't wish to put the pictures in a third-party hosting environment. I don't wish to use PHP, simply because that's another run-time to worry about, I might relent and use something dynamic if it's Python or Perl based (as I can maintain things written in those). I currently have: Apache serving static files, Album-generated, some sub-directories to divide up the content to be a little more manageable. Something like Album but with pagination already handled would be great, but I'm willing to have something a little more dynamic, if it lets people comment or caption and store the extra data in something like an sqlite DB. I'd want something light-weight, not a full-blown CMS with security updates every three months. I don't want to upload pictures of other peoples' children into a third-party free service where I don't know what the revenue model is. (For my site: revenue is none, costs out of pocket). Existing server hosting is *nix, Apache, some WSGI. Client-side I have MacOS. Any advice?

  • Wired connection to windows ISC stopped working

    - by cmpickle
    I have had my Linux box connected to the internet through a Windows computer by wiring them together with a cat5 cable then the Windows is connected wireless to a router. This setup has worked since I got the Linux box but just yesterday stopped working. The changes that occurred were: I changed networking so that I was connecting the Linux box and Windows computer through a second router so during that time the Linux box went through a router to connect to the Windows computer that was still connected wireless to the first router. The Internet didn't work on the Linux box at the time they second router was involved when I removed it and directly connected the Linux box and Windows the Internet worked again. Another thing that changed was that I had disconnected my Windows computer from all network connections and deleted them to make my Ethernet work better. Also at that time my dad had I connect the Windows to a third router and changed some settings in it. After reconnecting this time the connection between the router and the windows would not establish. If anyone has any ideas as to why this is I would greatly appreciate it!

  • Why is apt-cache so slow?

    - by Damn Terminal
    After upgrade to Trusty (14.04) from Saucy (13.10), all apt operations are very slow. Even those that do not include downloading anything, or connecting to any servers. For example, displaying the apt policy # time apt-cache policy [...] real 0m8.951s user 0m5.069s sys 0m3.861s takes almost ten seconds! Mostly a weird lag right after issuing the command. And it's the same even if I issue the same command again. On another system it doesn't take a tenth of a second real 0m0.096s user 0m0.070s sys 0m0.023s The other system is a little beefier but there was no noticeable difference before the upgrade. It's the same with apt-get, anything apt-related. How do I find out the source of this lag and fix it? Additional info: # cat /etc/nsswitch.conf # /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed, try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis BTW is my understanding of how apt-cache works correct? It doesn't make any network connections when I run apt-cache policy, right? In case I'm wrong and it matters, here are my sources https://gist.github.com/anonymous/02920270ff68e23fc3ec

  • Can it be a good idea to lease a house rather than a standard office-space for a software development shop? [closed]

    - by hamlin11
    Our lease is up on our US-based office-space in July, so it's back on my radar to evaluate our office-space situation. Two of our partners rather like the idea of leasing a house rather than standard office-space. We have 4 partners and one employee. I'm against the idea at this moment in time. Pros, as I see them Easier to get a good location (minimize commutes) All partners/employees have dogs. Easier to work longer hours without dog-duties pulling people back home More comfortable bathroom situation Residential Internet Rate Control of the thermostat Clients don't come to our office, so this would not change our image The additional comfort-level should facilitate a significantly higher-percentage of time "in the zone" for programmers and artists. Cons, as I see them Additional bills to pay (house-cleaning, yard, util, gas, electric) Additional time-overhead in dealing with bills (house-cleaning, yard, util, gas, electric) Additional overhead required to deal with issues that maintenance would have dealt with in a standard office-space Residential neighbors to contend with The equation starts to look a little nasty when factoring in potential time-overhead, especially on issues that a maintenance crew would deal with at a standard office complex. Can this be a good thing for a software development shop?

  • For a large website developed in PHP, is it necessary to have a framework?

    - by Martin
    I am wondering if it is necessary to have a framework or if it is a must-have if I plan to make a large website. Large website could mean a lot of things: in other words, multiple dynamic web pages (40-50 dynamic pages, mysql content) and a lot of visitors (+- a million hits per month). The site will be hosted in a dedicated server environment. I know that it could simplify coding for a developer team, that it includes libraries and a lot of advantages. But I just feel that I don't need that. I think that learning how it works, managing it and installing it would take more time and I could use that time to code. I write PHP the simplest way I could (with performance in mind) and I try to reuse my code/functions/classes most of the time and I make sure that if another developer joins the team, that he won't be lost in the code. I am also planning to use MemCached or another Cache for PHP. As I said, the site will be hosted in a dedicated server environment but will be entirely managed by the hosting company. I am pretty sure the control panel for me to control the basic stuff will be Cpanel. For a developer like me that only knows PHP, Javascript, HTML, CSS, MYSQL and really basic server management, I feel that it seems to complicated to have a framework. Am I wrong? Is it worth the time to learn all about it? Thank you for your opinions and suggestions.

  • Is there any kind of established architecture for browser based MMO games?

    - by black_puppydog
    I am beginning the development of a broser based game in which players take certain actions at any point in time. Big parts of gameplay will be happening in real life and just have to be entered into the system. I believe a good kind of comparison might be a platform for managing fantasy football, although I have virtually no experience playing that, so please correct me if I am mistaken here. The point is that some events happen in the program (i.e. on the server, out of reach for the players) like pulling new results from some datasource, starting of a new round by a game master and such. Other events happen in real life (two players closing a deal on the transfer of some team member or whatnot - again: have never played fantasy football) and have to be entered into the system. The first part is pretty easy since the game masters will be "staff" and thus can be trusted to a certain degree to not mess with the system. But the second part bothers me quite a lot, especially since the actions may involve multiple steps and interactions with different players, like registering a deal with the system that then has to be approved by the other party or denied and passed on to a game master to decide. I would of course like to separate the game logic as far as possible from the presentation and basic form validation but am unsure how to do this in a clean fashion. Of course I could (and will) put some effort into making my own architectural decisions and prototype different ideas. But I am bound to make some stupid mistakes at some point, so I would like to avoid some of that by getting a little "book smart" beforehand. So the question is: Is there any kind of architectural works that I can read up on? Papers, blogs, maybe design documents or even source code? Writing this down this seems more like a business application with business rules, workflows and such... Any good entry points for that?

  • How to handle the different frame rate on different devices?

    - by Fenwick
    I am not quite sure how frame per second works on a web page. I have a Canvas game that involves in moving an image from point A to B, and measuring the time elapsed. The code can be as simple as: var timeStamp = Date.now(); function update(){ obj.y += obj.speed; text = "Time: "+ (Date.now() - timeStamp) + "ms"; } The function update() is called every frame. The problem is that the time elapsed is different from device to device. It is pretty short on my PC, but get longer on my iPad, and is much longer on my cell phone. I thought it is because the FPS is smaller on mobile devices, so instead of calling update() every frame, I call it every 1ms by using a setInterval. But this does not solve the problem. In my understanding, the function for setInterval is invoked based on the increment in system time, other than frame rate, so it should fix the problem. Am I missing anything here? If the setInterval function is called based on FPS, is there any way to get around with the FPS difference across devices? On a side note, I have sort of a "water simulator" on the same canvas. It involves in redrawing about 60 objects which can be 600x600 pixels for every frame, so it could be a frame rate killer. I am using Phaser.js but not really using much of its functionalities, if that helps.

  • MVC pattern synchronisation

    - by Hariprasad
    I am facing a problem in synchronizing my model and view threads I have a view which is table. In it, user can select a few rows. I update the view as soon as the user clicks on any row since I don't want the UI to be slow. This updating is done by a logic which runs in the controller thread below. At the same time, the controller will update the model data too, which takes place in a different thread. i.e., controller puts the query in a queue, which is then executed by the model thread - which is a single-threaded interface. As soon as the query executes, controller will get a signal. Now, In order to keep the view and model synchronized, I will update the view again based on the return value of the query (the data returned by model) - even though I updated the view already for that user action. But, I am facing issues because, its taking a lot of time for the model to return the result, by that time user would have performed multiple clicks. So, as a result of updating the view again based on the information from model, the view sometimes goes back to the state in which the previous clicks were made (Suppose user clicks thrice on different rows. I update the view as soon as the click happens. Also, I update the view when I get data back from the model - which is supposed to be same as the already updated state of the view. Now, when the user clicks third time, I get data for the first click from model. As a result, view goes back to a state which is generated by the first click) Is there any way to handle such a synchronization issue?

  • Improved Customer Experience, but at what Cost? See the DELL Computer experience with RTD

    - by Richard Lefebvre
    We can all probably agree that improving your customers' experience is a good thing. But a key question many people are asking is will it help your organization and, in particular, what are the financial benefits? That's a good question, especially when companies ARE experiencing phenomenal return on investment (ROI). Of course, there are many factors that impact ROI or other measures of success, but we'd like to share some success stories as examples of customer experience in action and delivering positive results. If you would like to learn more about the economics of customer experience, see Brian Curran's presentation at the Oracle Customer Experience Summit last month. In this series of blog posts, we'll share actual customer stories. Today's example is Dell, which uses Oracle Real-Time Decisions (RTD) and Siebel CRM as part of their customer experience portfolio to better understand their customers' needs and wants and provide consistent interactions. Regular readers of this blog are probably familiar with Siebel, but RTD may be new to many of you. RTD is a complete decision management solution that delivers real-time decisions and recommendations and automatically renders decisions within a business process to create tailored messaging for every customer interaction. What does that mean? In the video below, Dell describes how customer experience is important not just for one interaction channel, but across all "vehicles." RTD is helping Dell understand customer behavior and communicate with the customer in a more relevant manner, across all communication  or interaction channels including sales and service call centers, email marketing and online. Dell continues to expand use of RTD because the benefits are showing up in sales, service and marketing results including 19% increase in close rates, faster issue resolution and 40% improvement in revenue per click in email marketing.

  • Advantages of Scala vs. Groovy with JAVA EE 6 Applications.

    - by JAVA EE Wannabe
    Please let me first emphasize that I am not looking for flare wars. I just want advices from people who have real experiences. I started learning JAVA EE 6 as real newbie and am having had time choosing what tools to use. First problem is what is the advantage of using Scala vs. Groovy with Java EE 6 apps over Java? I've seen on some blogs people mentioning you gonna write less code but as a newbie I don't know what other advantages and disadvantages are there. Second problem is Netbeans 6.9 or Helios 3.6.1? I realized that with eclipse I can easily mix EE 6 applications with Groovy or Scala without any problems (I only did this by displaying a String message from Scala and Groovy classes.). With Netbeans the only I can think of is having separate Java project libraries and using the jars in my web app. But also realize to the extent of my little knowledge Netbeans has better support for Java EE 6. Please need your expert advice. Thanks.

  • handling multiple interviews / offers [closed]

    - by farble1670
    What's the best way to handle a situation where you have, or expect to have multiple offers? The ideal situation is that your several offers come in about the same time, and you make a choice. this is not how it happens though. You may have an offer, and several near-final interviews lined up for the following days or weeks. One way to handle it would be to ask for a longer time to decide on the first offers you receive. 2 weeks? This gives time to rush the rest of the things you have going through to an end. i question whether asking for 2 weeks to decide is reasonable though. My guess is that an employer would see through that and force your hand. Another way to handle it would be to accept the first offer, and ask for a reasonable period before your start date, then simply "quit" the first position before you ever start if something better comes along. On one hand, employment is at-will, and employers exercise this fact regularly. On the other hand, it seems morally the wrong thing, and has the potential to burn some bridges. And of course the last option is to simply evaluate each offer in isolation, and accept or reject within the given time frame. any thoughts?

  • PHP Debugging

    - by Bob Porter
    Originally posted on: http://geekswithblogs.net/blogofbob/archive/2013/06/25/php-debugging.aspxI have been experimenting setting up a PHP development environment. I have been trying on Windows, Linux (Ubuntu) and Mac OS X. So far my favorite environment is on Mac OS X. I have tried a number of IDE's and debuggers as well.  IDE's Eclipse with the PDT Add On The PDT version of Eclipse Aptana Zend Netbeans  Debuggers Zend XDebug So far the only environments that I could get running quickly were Zend and Netbeans. Eclipse is a nightmare of versions and capabilities. I could only get Eclipse working well on Windows. On Ubuntu I was able to get the debugger working once. Thats it, one session, then it never worked again. I love the Zend tools and environment and it worked well everywhere I tried it, but it was beyond my budget.  Aptana also worked best on Windows, on Mac OS X it was fragile and I never could get debugging to work.  Netbeans worked first time, every time, every where. With one oddity, after several debugging sessions the debugger would refuse to connect. On every platform, I would end having to reboot to restore debugging, which would then work correctly for quite some time. I am sure I will discover that some process is hanging and there is a less intrusive way to clear the issue, but for now rebooting always works. In a future post I will go over how exactly I set my environment up, for now I have decided to stay with OS X. By the way, I did NOT use MAMP or the Zend Server, I stuck with PHP compiled and built from source, as well as Apache and MySQL installed locally. I use Homebrew as a package manager for OS X. I tried PORT but did not like the fact I had to sudo all the time to use it, and it installed things in /opt which I was not used to. Homebrew does sandbox the apps but it is nice enough to symlink them to their "normal" locations usually in /usr/local.

  • two guitexture that do not work together

    - by London2423
    I have two GUITexture that move left and right a cube. Is pretty strange but together they don't work. If I activate only one it works. To be more specific: If I have the left GUItexture alone in the game the cube move left. If I have the right GUITexture activated alone the cube move right. Seems all fine I thought but If I have both of them the cube move only right and not left. Where is the mistake? Here is the code inside the GameObject cube for Right move void OnMousedown () { transform.position += Vector3.right * Time.deltaTime; } For Left move void OnMousedown () { transform.position += Vector3.left * Time.deltaTime; } And this is the left GUITexture code //move the cube left Cube.GetComponent<Left> ().enabled = true; left.transform.position += Vector3.left * Time.deltaTime; This is the right GUITexture //move the cube right Cube.GetComponent<Left> ().enabled = true; right.transform.position += Vector3.right * Time.deltaTime; What is the reason for this? I hope someone can help me.

  • Choosing the correct network protocol for my type of game (its Wc3 Warlock style)

    - by Moritz
    I need to code a little game for a school project. The type of the game is like the Warcraft 3 map "Warlock", if anyone doesnt know it, here is a short description: up to ten players spawn into an arena filled with lava, the goal of each player is to push the other players into the lava with spells (basically variations of missiles, aoe nukes, moba spells etc) http://www.youtube.com/watch?v=c3PoO-gcJik&feature=related we need to provide multiplayer-support over the internet, for that reason I am looking for the best network protocol for this type of game (udp, tcp, lock step, client-server...) what the requirements are: - same/stable simulation on all clients - up to ten players - up to ~100 missiles on the field - very low latency since its reaction based (i dont know the method wc3 used, but it was playable with the old servers) what would be nice (if even possible, since the traffic might be too big): - support for soft bodies over the network (with bullet physics), but this is no real requirement I read several articles about the lock step method used for RTS games, this seems to be great, but does it fit for real-time action games too (ping-related)? If anyone has run into the same problems/questions like me, I would be very happy about any help

  • I don't understand how TDD helps me get a good design if I need a design to start testing it

    - by Michael Stum
    I'm trying to wrap my head around TDD, specifically the development part. I've looked at some books, but the ones I found mainly tackle the testing part - the History of NUnit, why testing is good, Red/Green/Refactor and how to create a String Calculator. Good stuff, but that's "just" Unit Testing, not TDD. Specifically, I don't understand how TDD helps me get a good design if I need a Design to start testing it. To illustrate, imagine these 3 requirements: A catalog needs to have a list of products The catalog should remember which products a user viewed Users should be able to search for a product At this points, many books pull a magic rabbit out of a hat and just dive into "Testing the ProductService", but they don't explain how they came to the conclusion that there is a ProductService in the first place. That is the "Development" part in TDD that I'm trying to understand. There needs to be an existing design, but stuff outside of entity-services (that is: There is a Product, so there should be a ProductService) is nowhere to be found (e.g., the second requirement requires me to have some concept of a User, but where would I put the functionality to remind? And is Search a feature of the ProductService or a separate SearchService? How would I know which I should choose?) According to SOLID, I would need a UserService, but if I design a system without TDD, I might end up with a whole bunch of Single-Method Services. Isn't TDD intended to make me discover my design in the first place? I'm a .net developer, but Java resources would also work. I feel that there doesn't seem to be a real sample application or book that deals with a real line of business application. Can someone provide a clear example that illustrates the process of creating a design using TDD?

  • How do you keep down your urge to learn many things [closed]

    - by devsundar
    One of the difficulties i have is to lower my urge to learn new things (Languages, tools, frameworks etc.). I know it's good to stay the bleeding edge, but at the same time i want to learn things properly. I really see that i need to strike a balance between staying bleeding edge and knowing things properly. For example: Before choosing Arch (Desktop), Ubuntu(Server) and Knoppix(Portable) -- depending on situation -- as favourite distributions. Virtually i have tried all popular linux distributions. You name any popular linux (Redhat, Ubuntu, Arch, Suse, Knoppix, Slax, Slackware) i have tried it for some time. In fact i have spent few years experimenting the operating systems. Before choosing Python, Javascript (nodejs). I have tried all the languages i cameacross Scala, Haskell, Erlang, Ruby, Python, Perl, Scheme. Same applies for database. All popular db RDBMS (Oracle, Mysql, Postgres, SQLite[Favourite] etc) and NoSQL (Mongo, Couch, Neo4j etc.). Advantages i see: We get a overall picture of the technologies/tools/languages. It's useful to select the right tool for the job. We develop a taste and choose the One we like. Disadvantages: I feel that i spend somuch time and see a need to strike a balance. In summary, for e.g. If i see a blog post in HackerNews about CofeeScript i will try it out irrespective of what i am currently learning (Say Haskell). I switch back to learning Haskell, then again i see DART i check it out. And this continues.. Effectively i take more time to learn Haskell, but learnt about other new stuff on the way. The quetion i have is how do you strike a balance between staying bleeding edge and learning properly.

  • How do you tell if advice from a senior developer is bad?

    - by learnjourney
    Recently, I started my first job as a junior developer and I have a more senior developer in charge of mentoring me in this small company. However, there are several times when he would give me advice on things that I just couldn't agree with (it goes against what I learned in several good books on the topic written by the experts, questions I asked on some Q&A sites also agree with me) and given our busy schedule, we probably have no time for long debates. So far, I have been trying to avoid the issue by listening to him, raising a counterpoint based on what I've learned as current good practices. He raises his original point again (most of the time he will say best practice, more maintainable but just didn't go further), I take a note (since he didn't raise a new point to counter my counterpoint), think about it and research at home, but don't make any changes (I'm still not convinced). But recently, he approached me yet again, saw my code and asked me why haven't I changed it to his suggestion. This is the 3rd time in 2--3 weeks. As a junior developer, I know that I should respect him, but at the same time I just can't agree with some of his advice. Yet I'm being pressured to make changes that I think will make the project worse. Of course as an inexperienced developer, I could be wrong and his way might be better, it may be 1 of those exception cases. My question is: what can I do to better judge if a senior developer's advice is good, bad or maybe it's (good but outdated in today context)? And if it is bad/outdated, what tactics can I use to not implement it his way despite his 'pressures' while maintaining the fact that I respect him as a senior?

  • Should I go with Java or Python for my next project, after using PHP for 5 years? [closed]

    - by vim
    I have a full-time PHP job and I've been working with PHP for 5 years. I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.
