cerbero | Get validation error from database constraint | Validation library

kandi X-RAY | cerbero Summary
Uniqueness validation does not guarantee uniqueness. Only the database constraints do this. But there is a flaw - when database constraints fail, an exception is thrown, and even when we catch it, the validation error is not set. This gem solves the issue. It catches the database constraints exception, revalidates and returns false from save. To use it, you should set both validation and database constraint. Then even if uniqueness validation mistakenly let you in, it will break the database constraint, then revalidate and the validation will tell you the truth.

QUESTION
I am trying to compile gstreamer 1.14.4 to take advantage of the webrtc module. I was able to successfully compile it using cerbero on my raspberry pi but I have an issue where when testing my webrtc application I get a segfault after I send an offer and the pipeline has started playing:

Answered 2018-Dec-31 at 18:04Answer is here:
you essentially have to remove the python3-gi and python3-gobject packages then install them via pip. Afterwards you have to replace the systems libffi with the one you built using cerbero.

I'm trying to do the following:

QUESTION
So I am trying to use makefiles. In the sequence of subsequent makefiles, I have one with the following code:
...ANSWER
Answered 2018-Feb-26 at 13:31There can be lots of different pattern rules to build a single target (consider how many different ways there are to build an object file!) So, if GNU make needs to build a target it will go through all the pattern rules to see if they match. If one doesn't match it's not an error: GNU make simply goes to the next one. If none match, you get the error you see.
For a pattern rule to match, first the target has to match the pattern. Second, all the prerequisites have to either exist, or be buildable using other rules. Since you have a pattern rule where the target matches, if it's reporting that the rule doesn't match it must mean that one or more of the prerequisites don't exist and can't be built.
You don't say what the value of the TARGET variable is, but the prerequisite avr-micropnp.$(TARGET) apparently doesn't exist and can't be built.
If you can't figure out why, you can run make with the -d option. It generates a ton of output but if you search through it you will find out why make ignores this pattern rule.
QUESTION
Goodmorning my dears, I'm going crazy with nodejs. I'm trying to realize the backend for a simple user management webapp powered by NodeJS, using Passport-Local and Sequelize libraries. Right now I just designed the user model. The main problem I have is that the signup process gives me an error: it looks like that I'm working on an undefined object. Could please someone help me in figuring out what's going on?
here is my code (merged with some solutions I found on internet - obviously nothing works, according to Murphy's laws).
Could please Javascript programmers forgive me if the code literally sucks. My excuse is that it is my first programming attempt in Javascript, I MUST do it for a project and last (excuse) but not least I grew up with C and microchips.
ERROR:

QUESTION
In a conversion project, I have modified and remodified an existing makefile chain but managed to break it. The makefiles need to follow a different chain for when I'm compiling for an AVR project without Contiki and one with (and some extensions on top). The one without works, the one with does not anymore, since it also needs to take into account the makefiles of Contiki. I'll try to be complete but leave out unneccessary details.
Using the terminal from /CerberOS/uJ/Build/, I execute the following command:

Answered 2017-Apr-14 at 08:18I have solved this problem myself.
That's right, it's the tool chain's problem, but the tool chain in {ndkroot}/toolchains can not be used directly, otherwise various compiling errors would follow.
Firstly I make my own toolchain with the tool given by ndk:
QUESTION
I want to build a manual sandbox to analyze malwares on Windows systems. I mean a manual environment, not something automated like Cuckoo Sandbox.
There are many tools and I selected some of them, but I can't really see if each of this tool is worth it or not. Can you say me what you think and if these tools are useful for my sandbox?
First I consider some of them are unavoidables like IDA, winDBG, Wireshark, npcap, an HTTP Proxy like Fiddler, the Sysinternals suite, Volatility, maybe Foremost.
Then there are others tools I never really tried but which seems to be interesting. About static analysis, I have spotted the following tools and I would like to have an eventual feedback about it : Log-MD (a tool which look at the system using advanced Windows audit policies), Cerbero Profiler, Pestudio, Unpacker (it seems it is an automated tool to unpack binaries, seems faster but I am bit skeptical but I'm not a RE specialist, if you know this tool...), oledump.py by Didier Stevens (to identify various elements like heuristic patterns, IP, strings)...
About dynamic analysis, I noted Hook Analyzer (statically analyze elements with heuristic patterns and allow you to hook applications), Malheur (detect "malicious behavior"), ViperMonkey (detect VBA macro in Microsoft Office documents and emulate their behavior.
Do you have any recommandations about my setup and tools I could have forgotten? I want to analyze classic malicious elements (PE, PDF, various scripts, Office documents, ...).
About malware evasion, is there a risk a malware refuse to be analyzed while detecting RE and analysis tools?
Finally should I use Internet in the sandbox? Most of malwares today use C&C server and I see that some sandboxes are built with simulators like iNetSim but since the connection is not real, will I lost some information?
Thank's!
...ANSWER
Answered 2017-Mar-29 at 08:18You might want to consider the SEE framework to build your analysis platform.
Its plugins based design will allow you to integrate scanning tools in a pretty flexible manner.
Bear in mind that lots of malware inspect the execution environment and, if any RE tool will be spotted, will refuse to run.
For what concerns the Internet connection, it depends on how much information you want to gather. It is indeed true that lots of malware communicate with C&C nowadays, yet they must ensure their persistence on the target machine.
Therefore, the injection mechanism will still be executed even if Internet connection is absent. My 2 cents on the matter is to run without Internet by default and activate it only when necessary.
