Let me preface this by explaining why I’m asking. I have a very inexpensive prepaid cellular plan, but the drawback to it being cheap is that the access point is located in Hong Kong, meaning all the data on that line must go through at least one server in Hong Kong. The plan allows you to change the APN settings, meaning in theory (I may be wrong here, I don’t know much about this), any access point reachable from the network could be used to route data. If this assumption is correct, I am interested in running my own access point, to make my connection faster, by avoiding the need to route through servers across the world. I tried searching this on google, but to no avail. Does anyone know if this is possible? Or what software I could use, if it exists?
(Also, I’m sorry if this is the wrong forum, but it seemed like the best match based on other things when searching for “cellular”)
Thank you.

thank you all for reading my question~
Before asking some (2~3) questions, I will briefly explain what I am trying to do. I am trying to build a turn based multiplayer (1 vs 1) game. I have a little knowledge of Swift/IOS development, mysql, html, and jsp. I am planning to learn php since many people say combination of mysql and php is good for ios back-end programming.
Here are actual questions:
Do I need to get a droplet from places like Digital Ocean and deploy my own server? Or is it possible to use web hosting such as bluehost for this purpose?
This is the part which I have no clue about... How do I actually develop a multiplayer game? I can guess that this has something to do with tcp/ip socket programming. My experience with tcp/ip programming did not require mysql or something similar if I remember it correctly. In that vein, what's the role of some database like mysql when it comes to developing a multiplayer game? Of course it becomes handy when saving scores and achievement; however, I do not know why it is required for finding a match and establishing a connection. Wouldn't a private server needed instead for receiving and sending sockets? Does this mean I have to lease a dedicated server and setup everything by myself?
It seems like there are more than three questions... sorry for asking too many questions. I am a noob programmer and needs many advice from experts!
Is is necessary for me to deploy a web application for handling all backend stuffs? By the way, I am trying to avoid having users make an account. As a result, if I have to manage each user, maybe keeping each user's unique phone id can help me distinguish each user?
I have looked into both Google's and Apple's free game match system... It is very tempting to use them, but my friends designed game match screen and separate ranking systems. As so, I need to come up with a way to solve this conundrum. Please help me!!! Thank you all for reading my question again and help a poor soul here...
I Program my local schools program launcher which allows students to get on the internet with an randomly generated key provided by a teacher. This is done by changing the proxy in Internet explorer to the one needed for the internet and the wb filter.
With the schools website and learning resources gradually moving to offsite hosting the internet key is needed for the students to access them. What the school would like is a way to enable these websites without unblocking the rest of the internet unless the internet key is given to the student.
The two ways ive come up with doing this by googleing is to block all websites in IE content adviser exept those that are allowed wthout the key. Or to create anouther proxy in delphi which the program can make ie point to and will only allow certain websites through to the real proxy.
I am reasonble fluent in simple delphi functions with an a level in computing but dont have a clue where to start with this and would appreciate any help.
Don't go through the DIY path - use a proxy with blacklist/whitelist functionalities, you can also set up a "transparent proxy" through which all internet traffic is routed and doesn't require to setup the proxy in browsers. You can also use proxy authentication to setup who can access what.
In Delphi you will end up to write a proxy with the same functionalities. If you don't have a very good rason to write your own proxy, it's far better to go through an already existing solutions, which also is already tested by a lot of users. There are commercial and opensource/free ones.
If you really like to write a proxy in Delphi:
A good knowledge of how TCP, HTTP(S), and a proxy works is required.
The application needs to be a service, and should be robust or accessing the Internet may be become impossible.
The application will have to serve concurrent requests, thereby it needs to be multithreaded (Indy offers a basic HTTP proxy component - how well it scales I do not know, and it implements basic features only).
If you need authentication, knowledge of authentication methods and if integrated authentication is needed, how Windows auhtentication works.
It should be tested with all the browser type used.
Although a very interesting app to write from scratch if you liked to learn about that all, if you have a "business need" it's better to use an already existing one.
+1 and the proxy may cache some of the Internet resources, so the whole Internet experience will be smoother with such a tool.
I'll recommend using a linux box (some old PC can be revamped into this) with Squid, just to separate your students network to the Internet. There is a lot of info on the Internet about that, and also dedicated linux distributions: a lot of schools around the world had the same problem!
OpenDNS is the best place to start. Put that up, set all PCs to use it, and that'll take care of most of your problems.
The nature of our business often has 2-3 remote developers working on a single project (mostly Rails), and each one currently has carte blanche access to source so they can checkout, run, and develop locally.
The problem is any one of them could ship the whole base out the back door. Overseas legal action seems futile.
I'm guessing the best way would be separation of duty type of strategy where a contractor only gets specific portions of code - but how can they run and test the full project?
I'm looking for advice, strategies, or even software solutions to mitigate this risk.
Thanks a ton.
You should really allow only trusted people to handle your family jewels. I can't think of any stronger sign of trust a software company can show than to give someone complete access to their source.
That being said, a few ideas come to mind.
If they're consultants, you should see if you can get some kind of business agreement with an entity in the remote country that can take care of local legal hassles for you. US companies with offices in India do this all the time.
Perhaps you can give access to non-important pieces of the software to the untrusted parties and have them work only on that? The unit testing can be done by them on the pieces but the integ. tests that require the entire system have to be done by you.
It might also be possible for them to use the 'important' parts of the code as a service from a server you provide rather than as modules locally. Admittedly, this requires some reengineering but it might be worth it.
The bottom line is what Stephen said. Low priced off-shore contractors come with certain liabilities. If you're not willing to accept that, you'll have to change your mode of working.
I don't think there's much you can do about it. Either take the risk, or don't use off-shore contractors.
But I'd balance this with an honest assessment of how valuable your code is to you and to a supposedly dishonest contractor. If it is really valuable, then you should be able to afford to take legal action to protect it ... even in a difficult legal environment.
Well, if you don't trust your developers enough to let them work with your code, then don't hire them.
I don't see any way you can meaningfully limit their access to code without seriously impacting their productivity. Even if you could compile some of the code, it's very useful to have access to the full source to understand problems and bugs.
At any rate, you may be overestimating the threat: Most kinds of piracy would be possible even with the binary, and without the infrastructure and customers your company provides, the stolen code is probably not worth much.
As part of a web-application I'm building, I need to be able to scan the remote user's machine for viruses / malware, before they can continue using the web-application ... something like the McAfee On-Demand Scan.
I'm assuming that ActiveX would be the way to go (since all the On-Demand scanners of the antivirus companies seem to be ActiveX-based).
I'm a bit stuck on how to solve this problem. I'm hoping I don't have to rustle up something from scratch.
Does anybody have any ideas ? Is it possible to integrate some already available component into my code to do this ?
Do let me know if there's more information you need.
Regards,
Sonal.
Short Answer: Just don't do this.
Long Answer: I would seriously re-evaluate your requirements here. Forcing a virus scan from a webapp is essentially impossible to do properly, and serves no real purpose from the perspective of the webapp. The whole point of the web is that it's a request initiated by the user, and run inside a sandbox. Forcing access to the rest of the machine for something like a virus scan is deliberately the exact opposite of the way it is meant to work
The only thing I can think of which would be sensible would be to offer an on demand scan, for which you would be best to redirect your users to an expert in the area - Panda ActiveScan is probably as good as any. But services such as these rely on downloadable program anyway in the form of java applet, browser plugin or similar - it's not done over the web.
Is the user part of your company? Is this an application that they will be required to use as part of their employment? If not, I can hardly see people visiting your site and saying "Oooh... he wants me to download and run a program on my machine!" Sounds like a great way to get your site on a bunch of "block lists".
Also, do you have a commercial arrangement with a virus scanning company that would allow you to install multiple copies of their commercial software on people's machines? I'm guessing not.
Really, I have to agree with Colin. This idea sounds dead before it even starts.
I have to confirm the detail of my gradutaion project recently.
My setup a goal for myself, that is it should have values( maybe as a opensource project or tools that can be use by others).
Can you suggest some ideas or projects pertaining to one of :
Web architect, Social Media, Ruby, ROR, Testing.
Thanks!:D
First choose something that both interests you and is in the scope of your abilities.
After you have made such a choice, formalize the decision, perform research and, build requirements; at this stage one can still set "how big a bite they can chew". Most professors I have dealt with are understanding of partial implementations as long as the expectations have been previously established.
Finally, decided on the tools/language and approach for implementation that best fits in the requirement and resources (this includes your time, desired level of effort vs payout, and ability).
I personally find web work absolutely dull, but if I were to write something new, by choice, that was "web-related" and "social" it would be a multi-user interactive whiteboard which is in turn an extension of a real-time collaborative document. (I actually used this as one of my own projects, albeit I focused on a specific protocol implementation.)
i just had this thing a while ago .... and i really needed some help with that same problem ....
i gut a couple of ideas, witch i already used one of them, so i'll suggest the other:
its a network monitoring system based on "SNMP" protocol, gets it's data from the snmp agent on the desired machine (witch can be a computer, a router, a printer, ... ,any thing connected to the network), and alert the administrator (when somthing wrong is there like too many ports are open, or denial of service problem, or too many tcp packets, so it might be a tcp ping problem, ...) with any way u would like to (email, sms, a live ajax warning, ...) ...
sorry .... it sounds messy, but basically it will be like the "CACTI" or the "openNMS" systems (just google them), and it's based on alot of technologies ,thing like: ruby, mysql(to save the actions and to have users DB), linux(i would use Debian), SNMP agents, cron (to schedule the basic system working), SSH/telnet (take a reaction of some harmful action), PHP/RubyonRails to build an web interface that can also connect to your database, ...
i know it sounded like a big fat thing to do, but it's not that hard .... i can provide more things if u want, caus i worked some kind of a specification for this thing.
When I was in college, I used to look into a lot of the programming contests (which involved 3-4 months of projects). Recently came across https://tgmc.in/project_scenario.php. Quite possible that you can get some ideas after reading these project descriptions!
