Derfor er det vigtigt for våbenejere at forstå og overholde de korrekte kaliberspecifikationer for deres skydevåben.
Betydningen af 7-kaliber:
Udtrykket "7-kaliber" betegner specifikt en kuglediameter på syv gange diameteren af skydevåbnets løb. For eksempel, hvis et skydevåben har en løbsdiameter på 0,30 tommer, vil en 7-kaliber kugle til det skydevåben have en diameter på 0,30 * 7 = 2,10 tommer.
I praksis er "7-kaliber" dog ikke et standardbegreb i skydevåbenindustrien. Kaliber er typisk udtrykt som hele tal eller i millimeter. Ikke desto mindre kan konceptet med en 7-kaliber kugle forstås som et hypotetisk scenarie til illustrative formål.
Anvendelser og variationer:
Konceptet med 7-kaliber kan variere afhængigt af konteksten. For eksempel, i diskussioner om kugledesign eller ballistik, kan udtrykket bruges til at beskrive længde-til-diameter-forholdet af et projektil. En 7-kaliber kugle kan indikere, at kuglens længde er cirka syv gange dens diameter.
I nogle tilfælde kan skydevåbenentusiaster og eksperter bruge udtrykket i daglig tale til at beskrive kugler eller patroner, der er væsentligt længere eller kortere end standarden for en bestemt kaliber. Denne variation kan påvirke faktorer som kuglestabilitet, mundingshastighed og ballistisk ydeevne.

I wonder if someone could help.
I have 2 iPhones, one with 17.4.1 and another 14.7.1.
I am connecting both of them on a hotspot.
In that hotspot i am blocking captive.apple.com for 5 sec after user authentication, so the done/ok button not to appear straight away.
The user ends up in a landing page that has a connect button and redirects him to another landing page.
With the 14.7.1 this works great the done/ok button appears but with the 17.4.1 it stays as cancel even though the device has access to captive.apple.com.
Any ideas?
Thank you in advance. | mike_dodbiba_55a987925a78 |

1,884,298 | Step-by-Step Guide To Install OpenCV For Python | OpenCV is an open-source computer vision library that provides a comprehensive set of tools for image... | 0 | 2024-06-11T11:16:12 | https://dev.to/codetradeindia/step-by-step-guide-to-install-opencv-for-python-91m | opencv, python, aiandml, computervision | OpenCV is an open-source **[computer vision](https://www.codetrade.io/blog/essential-value-of-computer-vision-in-a-digital-world/)** library that provides a comprehensive set of tools for image processing, video analysis, and machine learning.
It is written in C++ and Python, and available for a variety of platforms, including Windows, Linux, and macOS. It is easy to learn and use, making it a popular choice for both beginners and experienced developers.
## **Steps to Install OpenCV For Python**
OpenCV for Python is a library of Python bindings designed to solve computer vision problems. It is built on top of the OpenCV C++ library and provides a convenient way to use OpenCV in Python programs.
To install OpenCV-Python (also known as cv2) on your system, you can use the Python package manager pip or conda command in Anaconda. The installation can be performed in the following steps:
### **STEP 1. Create Environment**
A virtual environment is an isolated Python environment that has its own Python interpreter, standard library, and pip package manager.
This makes it easy to isolate different Python projects and avoid conflicts between different versions of **[Python packages](https://www.codetrade.io/blog/choose-python-libraries-modules-packages-and-frameworks-for-your-project/)**. Use the given command to create a new Python virtual environment.
```
$ python3 -m venv your_env_name
```
To create a virtual environment, you can use the ‘python3 -m venv’ command, where ‘your_env_name’ is the name of the virtual environment you want to create. For example, to create a virtual environment named ‘env’, you would use the following command:
```
$ python3 -m venv env
```
This will create a new directory called ‘env’ containing the Python interpreter, standard library, and pip package manager for the virtual environment. To activate the virtual environment, you can use the following command:
```
$ source env/bin/activate // env = your env name
```
Once the virtual environment is activated, the Python interpreter and pip package manager will use the packages installed in the virtual environment instead of the packages installed in the system Python environment.
### **STEP 2. OpenCV Installation**
To install OpenCV use the following pip command:
```
$ pip install opencv-python
```
The command installs the OpenCV Python module using the Python Package Index (PyPI).
By following these steps, you've installed OpenCV-Python using a virtual environment. This approach keeps your project's dependencies organized and avoids conflicts with other Python projects on your system. Now you're ready to explore the vast capabilities of OpenCV for computer vision tasks in your Python programs!

1,884,294 | How much UB is in my compiler? | C and C++ developers have two bug-related headaches: memory leaks and undefined behavior. As you can... | 0 | 2024-06-11T11:13:33 | https://dev.to/anogneva/how-much-ub-is-in-my-compiler-4gkc | cpp, programming | C and C\+\+ developers have two bug\-related headaches: memory leaks and undefined behavior\. As you can guess, I'll talk about undefined behavior—and about "my" compiler\. To be more precise, I'll talk about the set of compilers and the tools to develop them, the one called LLVM\. Why did I say "my" compiler? Our team really likes Clang, a part of LLVM, and regularly use it\.
We recently rechecked the LLVM code and even wrote [an article](https://pvs-studio.com/en/blog/posts/cpp/1126/) about it\. This is its sequel: we'll break down the errors that haven't been covered in the previous part\.
Foreword
Do you know what undefined behavior \(UB\) is? You can witness it when a programmer writes the code that the programming language rules let them write, and the code seems good, but the program works incorrectly \(or maybe correctly\.\.\.\)\. UB also means that the standard doesn't guarantee anything on your code\.
The program output depends only on the compiler and the target platform\. So, we can deduce that compilers can do almost anything with our program, even what we want them to\. However, it turns out that the error is just ably hidden, and it's just one's luck that everything is okay\.
Undefined behavior can occur for various reasons: the incorrect use of integer types, the incorrect memory handling, data races in parallel execution, and many others\. The scariest part is, it reveals only in certain scenarios\.
For example, you've already tested the program and deliver it to a client, but, suddenly, nothing works on their side\. Although, everything was fine five minutes ago on our side\. However, there are no logs or logical explanations here\. There's an explanation for this, though\. It's all UB fault\. However, we need to go through a tough debugging journey to realize it\.
Another scenario is possible: we update the compiler, build the program with it, and everything starts crushing\. All the tests are red\. Oh, gross\. All because of a couple code lines that the compiler has begun to use against you\.
The code on the agenda provides such an unusual experience that only one thought comes to mind: the developers do know something about UB that mere mortals may not\. They seem to "summon" it on purpose\.
**C\+\+ programmer's guide to Undefined behavior**
Meanwhile, we started posting a book about undefined behavior on our website\. The author is Dmitry Sviridkin, and the editor is Andrey Karpov\. Here's [the link](https://pvs-studio.com/en/blog/posts/cpp/1129/) to the first part\. You may also subscribe to the [monthly article digest](https://pvs-studio.com/en/subscribe/) so as not to miss other parts of the book and new curious content\.
**Fragment N1**
Let's start with an eternal classic in the world of errors—it's a null pointer dereference\.
```cpp
void LineTable::Dump(Stream *s, Target *target, Address::DumpStyle style,
Address::DumpStyle fallback_style, bool show_line_ranges)
{
const size_t count = m_entries.size();
LineEntry line_entry;
SupportFileSP prev_file; // <=
for (size_t idx = 0; idx < count; ++idx) {
ConvertEntryAtIndexToLineEntry(idx, line_entry);
line_entry.Dump(s, target, *prev_file != *line_entry.original_file_sp, // <=
style, fallback_style, show_line_ranges);
s->EOL();
prev_file = line_entry.original_file_sp;
}
}
```
The analyzer warning:
[V522](https://pvs-studio.com/en/docs/warnings/v522/) Dereferencing of the null pointer 'prev\_file' might take place\. LineTable\.cpp [363](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/lldb/source/Symbol/LineTable.cpp#L363)
As we can see, the analyzer points to the *prev\_file* variable\. And this is what the variable \(or rather its type\) looks like:
```cpp
typedef std::shared_ptr<lldb_private::SupportFile> SupportFileSP;
```
When we declare this way, *std::shared\_ptr* [is initialized with null](https://en.cppreference.com/w/cpp/memory/shared_ptr/shared_ptr#:~:text=1%2C2),empty%20shared_ptr.)\. [A](https://pvs-studio.com/en/blog/posts/cpp/0306/) null pointer dereference leads to undefined behavior\.
Let's have a special UB combo meter to count it\.
The UB combo meter: 0 —\> 1\.
**Fragment N2**
Errors usually occur throughout the code\. Want to see how just a single code fragment can plague your code with bugs?
```cpp
bool Sema::checkStringLiteralArgumentAttr(const AttributeCommonInfo &CI,
const Expr *E, StringRef &Str,
SourceLocation *ArgLocation)
{
const auto *Literal = dyn_cast<StringLiteral>(E->IgnoreParenCasts());
....
}
```
As you can see, the *E* pointer is dereferenced in the first line without check\. And then THIS happened\.
<spoiler title="Not for the faint hearted">

As proofs, I'll show you where the function is called in the first two warnings\.
Here's the first fragment:
```cpp
static void handleAssumumptionAttr(Sema &S, Decl *D, const ParsedAttr &AL) {
// Handle the case where the attribute has a text message.
StringRef Str;
SourceLocation AttrStrLoc;
if (!S.checkStringLiteralArgumentAttr(AL, 0, Str, &AttrStrLoc))
return;
....
}
```
Here's the second one:
```cpp
static void handleWeakRefAttr(Sema &S, Decl *D, const ParsedAttr &AL) {
....
if (AL.getNumArgs() && S.checkStringLiteralArgumentAttr(AL, 0, Str))
....
}
```
As we can see, 0 is passed as the second parameter in both cases\.
"UB can make your cat get pregnant, even if you don't have one\." Looking at the number of warnings, can you imagine how many cats could get pregnant?
Do you remember the UB combo meter? So, here's: 1 —\> 36\.
**Fragment N3**
Let's take a look at the following structure:
```cpp
struct ForceCodegenLinking {
ForceCodegenLinking() {
// We must reference the passes in such a way that compilers will not
// delete it all as dead code, even with whole program optimization,
// yet is effectively a NO-OP. As the compiler isn't smart enough
// to know that getenv() never returns -1, this will do the job.
// This is so that globals in the translation units where these functions
// are defined are forced to be initialized, populating various
// registries.
if (std::getenv("bar") != (char*) -1)
return;
(void) llvm::createFastRegisterAllocator();
(void) llvm::createBasicRegisterAllocator();
(void) llvm::createGreedyRegisterAllocator();
(void) llvm::createDefaultPBQPRegisterAllocator();
(void)llvm::createBURRListDAGScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
(void)llvm::createSourceListDAGScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
(void)llvm::createHybridListDAGScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
(void)llvm::createFastDAGScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
(void)llvm::createDefaultScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
(void)llvm::createVLIWDAGScheduler(nullptr,
llvm::CodeGenOptLevel::Default);
}
} ForceCodegenLinking; // Force link by creating a global definition.
}
```
In its constructor, a number of functions are called to create some entities\. We'll look only at the functions to which arguments are passed \(there are six\)\. For example, here are some of them:
```cpp
ScheduleDAGSDNodes *llvm::createBURRListDAGScheduler(SelectionDAGISel *IS,
CodeGenOptLevel OptLevel)
{
const TargetSubtargetInfo &STI = IS->MF->getSubtarget();
....
}
```
Or
```cpp
ScheduleDAGSDNodes* createDefaultScheduler(SelectionDAGISel *IS,
CodeGenOpt::Level OptLevel)
{
const TargetLowering *TLI = IS->TLI;
const TargetSubtargetInfo &ST = IS->MF->getSubtarget();
....
}
```
If we look at the function call in the constructor, we see that *nullptr* is passed as its first argument\. It's that first *IS* parameter that's dereferenced in the very first line of the function\.
It's strange code\. Perhaps the LLVM developers know something and can actually control UB\. Or perhaps they just want there to be more cats in our world :D
Every function with the first zero argument gets dereferenced\.
So, here are the analyzer warnings:
* V522 Dereferencing of the null pointer might take place\. The null pointer is passed into 'createBURRListDAGScheduler' function\. Inspect the first argument\. Check lines: 'ScheduleDAGRRList\.cpp:[3147'](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/llvm/lib/CodeGen/SelectionDAG/ScheduleDAGRRList.cpp#L3147), 'LinkAllCodegenComponents\.h:[40'](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/llvm/include/llvm/CodeGen/LinkAllCodegenComponents.h#L40)\.

* \.\.\. \(the other three are similar\)
The UB combo meter: 36 —\> 42\.
**Fragment N4**
Another snippet, another UB:
```cpp
Value *CodeGenFunction::EmitX86BuiltinExpr(unsigned BuiltinID,
const CallExpr *E)
{
....
unsigned SrcNumElts =
cast<llvm::FixedVectorType>(Ops[1]->getType())->getNumElements();
....
int Indices[16];
for (unsigned i = 0; i != DstNumElts; ++i)
Indices[i] = (i >= SrcNumElts) ? SrcNumElts + (i % SrcNumElts) : i;
....
}
```
The analyzer warning:
[V609](https://pvs-studio.com/en/docs/warnings/v609/) Mod by zero\. Denominator 'SrcNumElts' == 0\. CGBuiltin\.cpp:[14833](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/clang/lib/CodeGen/CGBuiltin.cpp#L14833)
The analyzer suggests us pay attention to *SrcNumElts*\. Let's get to the bottom of this\.
We can see that the ternary operator is used in the loop\. The check condition: *i* is greater than or equal to *SrcNumElts*\. When we have *SrcNumElts == 0* then* SrcNumElts \+ \(i % SrcNumElts\)* will be executed* *\(there are no checks above, *[getNumElements](https://github.com/llvm/llvm-project/blob/279a659e9772e48d95ad7d81f6deb00ee31e35e1/llvm/include/llvm/IR/DerivedTypes.h#L582C3-L582C46)* can return 0\)\. As we know, the behavior is [undefined](https://en.cppreference.com/w/cpp/language/operator_arithmetic#Built-in_multiplicative_operators:~:text=The%20result%20of%20built%2Din%20division%20is%20lhs%20divided%20by%20rhs.%20If%20rhs%20is%20zero%2C%20the%20behavior%20is%20undefined.) when [we divide by 0](https://pvs-studio.com/en/blog/terms/0085/) \(including division by modulus\)\.
The UB combo meter: 42 —\> 43\.
**Fragment N5**
Here's a small function consisting only of the *if* statements:
```cpp
static bool StopAtComponentPre(const Symbol &component) {
if constexpr (componentKind == ComponentKind::Ordered) {
// Parent components need to be iterated upon after their
// sub-components in structure constructor analysis.
return !component.test(Symbol::Flag::ParentComp);
} else if constexpr (componentKind == ComponentKind::Direct) {
return true;
} else if constexpr (componentKind == ComponentKind::Ultimate) {
return component.has<ProcEntityDetails>() ||
IsAllocatableOrObjectPointer(&component) ||
(component.has<ObjectEntityDetails>() &&
component.get<ObjectEntityDetails>().type() &&
component.get<ObjectEntityDetails>().type()->AsIntrinsic());
} else if constexpr (componentKind == ComponentKind::Potential) {
return !IsPointer(component);
} else if constexpr (componentKind == ComponentKind::PotentialAndPointer) {
return true;
}
}
```
Here's the analyzer warning:
[V591](https://pvs-studio.com/en/docs/warnings/v591/) Non\-void function should return a value\. tools\.cpp:[1278](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/flang/lib/Semantics/tools.cpp#L1278)
As we can see, the function has no *return* for the case when all the conditions are false\. This can happen because *enum class ComponentKind* contains another *Scope* value not provided here\. In such a case, the [behavior](https://en.cppreference.com/w/cpp/language/return#:~:text=Flowing%20off%20the,is%20undefined%20behavior.) is undefined\.
Undefined behavior doesn't necessarily mean that the function will return a random value \(*true* or *false*\)\. [It's exactly whatever you want it to be](https://pvs-studio.com/en/blog/posts/cpp/0917/)\.
The UB combo meter: 43 —\> 44\.
**Fragment N6**
This is the fragment that might seem safe:
```cpp
bool AppleObjCRuntimeV2::NonPointerISACache::EvaluateNonPointerISA(
ObjCISA isa, ObjCISA &ret_isa) {
....
if (index > m_indexed_isa_cache.size())
return false;
LLDB_LOGF(log, "AOCRT::NPI Evaluate(ret_isa = 0x%" PRIx64 ")",
(uint64_t)m_indexed_isa_cache[index]);
....
}
```
It doesn't seem bad, there's even a check for the index\.
However, there's still an error here\. If the stars align so that the *index* variable is equal to *m\_indexed\_isa\_cache\.size\(\)*, then IT will happen\. Yes, we'll get the [array overrun](https://pvs-studio.com/en/blog/terms/0071/) and, as a consequence, we'll catch undefined behavior\.
The analyzer warning:
[V557](https://pvs-studio.com/en/docs/warnings/v557/) Array overrun is possible\. The 'index' index is pointing beyond array bound\. AppleObjCRuntimeV2\.cpp [3308](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/lldb/source/Plugins/LanguageRuntime/ObjC/AppleObjCRuntime/AppleObjCRuntimeV2.cpp#L3308)
To fix it, just write like this:
```cpp
if (index >= m_indexed_isa_cache.size())
return false;
```
Here's exactly the same warning but a little lower in the code\.
Here's the analyzer warning:
[V557](https://pvs-studio.com/en/docs/warnings/v557/) Array overrun is possible\. The 'index' index is pointing beyond array bound\. AppleObjCRuntimeV2\.cpp [3311](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/lldb/source/Plugins/LanguageRuntime/ObjC/AppleObjCRuntime/AppleObjCRuntimeV2.cpp#L3311)
The UB combo meter: 44 —\> 46
**Fragment N7**
As the old saying goes, "all in good time"\. In the code fragment above, the pointer check is later than its dereference in the constructor initialization list:
```cpp
lldb_private::formatters::StdlibCoroutineHandleSyntheticFrontEnd::
StdlibCoroutineHandleSyntheticFrontEnd(lldb::ValueObjectSP valobj_sp)
: SyntheticChildrenFrontEnd(*valobj_sp) {
if (valobj_sp)
Update();
}
```
The analyzer warning:
[V664](https://pvs-studio.com/en/docs/warnings/v664/) The 'valobj\_sp' pointer is being dereferenced on the initialization list before it is verified against null inside the body of the constructor function\. Check lines: [99](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/lldb/source/Plugins/Language/CPlusPlus/Coroutines.cpp#L99), 100\. Coroutines\.cpp
The UB combo meter: 44 —\> 46
**Fragment N8**
In the last code fragment, let's go back to where we started\. It's a null dereference but in a different code fragment, though\.
```cpp
void SetInsertPoint(Instruction *I) {
BB = I->getParent();
InsertPt = I->getIterator();
assert(InsertPt != BB->end() && "Can't read debug loc from end()");
SetCurrentDebugLocation(I->getStableDebugLoc());
}
```
The analyzer warning:
[V522](https://pvs-studio.com/en/docs/warnings/v522/) Dereferencing of the null pointer 'I' might take place\. The null pointer is passed into 'SetInsertPoint' function\. Inspect the first argument\. Check lines: 'IRBuilder\.h:[188'](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/llvm/include/llvm/IR/IRBuilder.h#L188), 'OMPIRBuilder\.cpp:[5983'](https://github.com/llvm/llvm-project/blob/461274b81d8641eab64d494accddc81d7db8a09e/llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp#L5983)\.
The analyzer recommends to pay attention to the *I* parameter\. Well, let's do as it suggests and see where the function is called:
```cpp
if (UnreachableInst *ExitTI =
dyn_cast<UnreachableInst>(ExitBB->getTerminator())) {
CurBBTI->eraseFromParent();
Builder.SetInsertPoint(ExitBB);
} else {
Builder.SetInsertPoint(ExitTI);
}
```
It's another strange snippet\. If we look at the names of the *\(ExitTI* and *ExitBB\)* pointers and functions that are called via them *\(getTerminator\)*, we may get the impression that they're intentionally dereferenced using *null* to crash the program :D Although the result will be undefined\.
We get our "terminator" *ExitTI* from *ExitBB\-\>getTerminator\(\)*, and first cast it to *UnreachableInst*\. All that occurs in the condition of the *if* statement\. If the terminator is equal to null, the *else* branch will be executed, where this "cyborg" passed as an argument to the function, and immediately dereferenced\. Hasta la vista, baby\.
The UB combo meter: 47 —\> 48
Afterword about null dereference
The null dereference topic is as deep as a rabbit hole — or even deeper than we thought\. We suggest you have a bit of fun with this fascinating talk about \*\(char\*\)0 = 0;
<https://www.youtube.com/watch?v=dFIqNZ8VbRY>
Want to read something curious? Take a look at "[Compilation of gripping C\+\+ conference talks from 2023](https://pvs-studio.com/en/blog/posts/1120/)"\.
Conclusion
The UB combo meter displays 48 and the article is coming to the end\.
The undefined behavior examples seemed marvelous\. The curious thing is that developers didn't immediately find them while writing the code\. Undefined behavior is usually found in less obvious places, and that's why it's even harder to spot\.
It's important to bear in mind that developers have to keep an eye out for UB and other bugs all the time\. This requires attention and effort\. Even experienced developers may encounter undefined behavior and errors, especially when they work with new libraries or difficult, large systems\.
That's why I recommend you not ignore compiler and static analyzer warnings and always enhance your testing experience\. | anogneva |

It’s no secret that cash flow is what keeps a business running. Ideally, businesses will have enough money coming in to keep the wheels turning. But that doesn’t always happen. When revenues and expenses don’t quite line up, like economic difficulties or when a business opportunity arises, business owners need to be able to access credit right away to handle these costs. Per Sue Tse, this is why many entrepreneurs have small business credit cards that they must use smartly or get quickly buried.
To help us navigate the hazardous shallow waters of a business credit card, Richard “Capt’n” Henderson interviews Sue Tse, Manager of Tax & Advisory Services for 1-800Accountant. Sue is also one of those feared MBA’s!
Subjects Discussed
Subjects discussed with Sue Tse in the podcast included:
• Why should you open a small business credit card?
• What are some hazards to look out for when using a credit card?
• Smart business habits in using a credit card
• Good small business credit cards for a business’s specific needs
• Recommendations on applying for a credit card?
• When should you not apply for a small business credit card?

1,884,285 | MY PROGRAMMING JOURNEY | Hello everyone,I’m James emeka and I’ll be sharing with you my experiences as a Tech student learning... | 0 | 2024-06-11T11:08:11 | https://dev.to/james_emeka/my-programming-journey-2619 | webdev, programming, css, html |
Hello everyone,I’m James emeka and I’ll be sharing with you my experiences as a Tech student learning programming.
First of,I never knew anything about programming not until 2021 when I gained admission into the university to study computer science but before then I always admire sci-fi movies,advanced artificial robots used in carrying out different jobs ,evolution of technology over the years made me enthusiastic.Not to forget,after hearing the stories of how a lot of people had become rich and wealthy from the Tech industry e.g mark zuckerberg,Jeff bezos ,bill gates, Elon musk etc I said to myself that I can also do it.This motivated me to study computer science,Going into the university I discovered that there were different branches(fields) in computer science such as cyber security,app de&web development,artificial intelligence,data science ,system analysis etc it’s too broad to be studied as a single course but nevertheless we continue.
The first programming language that was introduced to me was c++,it is a powerful language but challenging due to its complex syntax and learning curve ;it has a lot of rules and exceptions that can be hard to remember.it is an object-oriented programming language .it took a long period of time before I could understand the basics .
Next was python ,yeah it was not hard to learn but it had its own challenges . Understanding the complexities of OOP, Decorators, Generators, Multithreading, Exception Handling, Regular Expressions.
The major challenge I was having then was owning my own laptop .learning to code on my schools computer desktop was stressful I always go to the computer laboratory or library to code .
The story changed for me when I was to do my Industrial Training (IT) at Tech firm called white creativity.The joy that hit me when my uncle sent me a brand new laptop.I quickly installed application,got my Visual studio code editor ready for work and then we Begin.
The first course I took was website development using HTML&CSS.it has an been an amazing journey ,easy to grasp .
One of the few steps to create a webpage are:
Step 1: Create a Layout.
Step 2: Set up the boiler code.
Step 3: incorporating elements like headings, paragraphs, and images in the layout
Step 4: Create the HTML content(Body).
Step 5: Create CSS for the layout.
Step 6: Create CSS to style individual elements.
Step 7: Add background color and style. There are more additional steps to these ones which are basics.
Although I’m still learning on HTML&css and my progress has been smooth .There are times I feel down but refused to give up and brace up for the future awaits me .listening to music helps my mind to concentrate .
Looking forward,I’m eager to learn more,dive deeper,try new languages and become a better programmer.
One thing I would love to tell people out there is that you don’t need to study computer science to become a programmer or go into other Tech related fields all you need to do is to register for online courses,watch online videos ,get a tutor or a coach that will guide you ,practice:To know it you have to practice consistently if possible get certified.

Hey everyone, In this blog we are going to see how you can create API Endpoints that perform SQL query on MySQL server. During this tutorial, we will be creating the workflow from scratch. You can choose to use different databases to perform similar actions. Before we start, make sure you have deployed N8N, we will be self-hosting it on [Elestio](https://elest.io/open-source/n8n?ref=blog.elest.io).
## What is N8N?
N8N is an open-source workflow automation tool that allows you to automate tasks and workflows by connecting various applications, services, and APIs together. It provides a visual interface where users can create workflows using a node-based system, similar to flowcharts, without needing to write any code. You can integrate n8n with a wide range of applications and services, including popular ones like Google Drive, Slack, GitHub, and more. This flexibility enables users to automate a variety of tasks, such as data synchronization, notifications, data processing, and more.
This application is a simple workflow that takes `id` as input and returns a record with the ID after querying the SQL server. The end of the workflow should look something similar to:
## Configuring Webhook
When you are starting, click on the "+" button and add the following **Webhook** and **MySQL** components. After that click on the **Webhook** component to configure it to accept the incoming request.
Once you click on **Webhook** you can copy the **Test URL/Production URL** , Select the HTTP Method. Here we are trying to make a **GET** request so we have selected it from the drop-down menu. Let's keep Authentication as none for simplicity but make sure while in production you add the authentication to provide security to the endpoints. Additionally, we will configure the response to be made **When Last Node Finishes** under **Respond**.
## Configuring MySQL Server
Now it's time to configure the **MySQL** component. In this configuration, we connect this component with our MySQL server that is hosted on the cloud. Here we have already deployed MySQL Server on Elestio and you can too by heading over to [Elestio Dashboard](https://elest.io/open-source/mysql?ref=blog.elest.io).
Once you click on **Credential to connect with** section and click on **Create New Credential**.
Now head over to your deployed MySQL service and copy all the information as it will be required to configure your N8N MySQL service.
This is a test database and table that is created for this blog. This will be useful when you write the query you want to run once the component is running.
Now, paste all the information copied before into the connection settings of the **MySQL** component.
Once the MySQL server is connected, head over to **Table** switch the criteria to **Name** and select the table name of your choice. Like in this case it is **student**. Now, under **Select Rows** set it up as
**Column:** Id
**Operator:** Equal
**Value:** `{{$json.query.id.toInt()}}`
## Testing Workflow
For testing your workflow you will see the **Test workflow** button. Click on it and paste the endpoint URL copied from the **Webhook** component in the earlier steps. Make sure you add the query property to it. In this case, it will be `?id=<Id from table>` so the final URL will look something like:
```
https://n8n-ygblb-u7774.vm.elestio.app/webhook-test/8b6ac879-866b-4048-bcba-b04b4efa3ee7?id=1
```
You should see output like below.
And done! You have successfully created an application that queries the SQL server and responds with the row data adjacent to the ID provided. You can form multiple such workflows based on the request type.
## **Thanks for reading ❤️**
Thank you so much for reading and do check out the Elestio resources and Official [N8N documentation](https://docs.n8n.io/?ref=blog.elest.io) to learn more about N8N. You can click the button below to create your service on [Elestio](https://elest.io/open-source/n8n?ref=blog.elest.io) and perform queries on your SQL server. See you in the next one👋

In today's fast-paced tech world, organizations aim to deliver software quickly, with better quality, and reliability. DevOps bridges the gap between development and operations, transforming the software development and deployment process.
In this blog post, we'll cover the basics of DevOps, its significance, principles, and essential tools and practices involved.
### What is DevOps ? 🔍
DevOps is a practice/culture (way of working) which improves the Organization's ability to deliver the applications & services quickly to the end users by ensuring :
➤ Proper Automation is in place
➤ Code Quality has been maintained throughout the SDLC process
➤ Continuous Monitoring / Observability setup is made available
➤ Continuous Testing is performed
In a nutshell, by breaking down the traditional silos, DevOps fosters better communication, collaboration and shared goals (delivering value to customers efficiently and consistently).
### Why is DevOps important ? 🤔
Imagine a company where software developers and IT operations work separately with little communication. This can cause several problems:
- **_Slow Delivery_ :** Developers take a long time to finish a feature, and the operations team takes even longer to deploy it because they weren't involved from the beginning.
- **_Frequent Errors_ :** The operations team encounters with bugs and issues when deploying software because they didn't fully understand the changes.
- **_Blame Game_ :** When things go wrong, developers blame the operations team and vice versa, leading to a lack of trust and co-operation.
**How DevOps solves these problems :** ✅
_Basically, DevOps unites the Development (Dev) team, who write code, and the Operations (Ops) team, who manage and deploy it, into one cohesive team. This integrated approach enhances efficiency, collaboration, speed, and quality throughout the software development and deployment lifecycle. This leads to:_
- **_Faster Delivery_** (⏩) : Both teams work together to release new features quickly.
- **_Enhanced Quality_** (👌) : Continuous testing and integration catches bugs early, reducing issues during deployment.
- **_Increased Efficiency_** (🔄) : Automation and standardization eliminate manual errors and streamline repetitive tasks.
- **_Better Collaboration_** (🤝) : Teams collaborate to solve problems instead of blaming each other, creating a positive work environment.
### Core principles 💡
DevOps rests on 3 core principles:
- **_Collaboration_** : It enables cross-functional teamwork, encouraging developers and operations personnel to work together seamlessly.
- **_Automation_** : It streamlines repetitive tasks, allowing teams to focus on innovation and higher-value work.
- **_Continuous delivery_** : This ensures that software is consistently and reliably deployed, reducing time-to-market and enabling rapid feedback loops.
### Why companies are adapting DevOps ? 🚀
- **_Market Competitiveness_** (🏆) : Implementing DevOps practices provides organizations with a competitive advantage by accelerating feature delivery and meeting customer expectations.
- **_Business Agility_** (🌐) : DevOps allows organizations to swiftly adapt to market changes, customer demands, and new technologies.
- **_Cost Optimization_** (💰) : Automation and efficient resource management result in cost savings in development, deployment, and maintenance.
- **_Enhanced Customer Satisfaction_** (😃) : Quicker releases, fewer errors, and higher-quality software lead to improved customer experiences.
### Important DevOps Tools and Practices ✨
- **_Continuous Integration(CI)_** (⚙️) : Automates code integration and testing using tools like Jenkins, GitLab CI, and Travis CI.
- **_Continuous Deployment(CD)_** (🚀) : Automates the release and deployment of applications with tools such as Jenkins, CircleCI, and Spinnaker.
- **_Configuration Management_** (🛠️) : Automates the management and provisioning of infrastructure using tools like Ansible, Chef, and Puppet.
- **_Containerization_** (📦) : Packages applications and their dependencies into containers for consistent deployment, utilizing tools such as Docker and Kubernetes.
- **_Monitoring and Logging_** (📊) : Provides visibility into application performance, infrastructure, and user behaviour with tools like Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana), and Splunk.
- **_Collaboration and Communication Tools_** (💬) : Facilitate cross-team communication and knowledge sharing through tools like Slack, Microsoft Teams, and Confluence.
### Software Development Life Cycle (SDLC) :
Software Development Life Cycle (SDLC) is a structured process used by software development teams to design, develop, test, and deploy high-quality software.
It offers a clear plan that helps ensure that the final product meets the required standards and customer expectations.
### Stages of SDLC
1. **_Planning_** : This is where it all begins. Teams gather requirements, analyze them, and plan out the project scope, timeline, and resources needed.
2. **_Analysis_** : Here, the project requirements are thoroughly examined to ensure they are feasible and align with business goals.
3. **_Design_** : With requirements in hand, developers create the blueprint for the software, including its architecture, database design, and user interface.
4. **_Implementation_** : Time to roll up the sleeves and start coding! Developers write the code according to the design specifications.
5. **_Testing_** : Quality assurance time! Testers put the software through its paces to uncover any bugs or issues. This includes unit tests, integration tests, and user acceptance testing.
6. **_Deployment_** : The big moment arrives! The software is released to production, ready for users to use.
7. **_Maintenance_** : Even after deployment, the work isn't over. Teams continue to monitor the software, fix bugs, and make improvements based on user feedback.
### Importance of DevOps in SDLC
DevOps is important in SDLC because it:
- **_Speeds up development_** : Faster building and releasing of software.
- **_Improves quality_** : Early bug detection through continuous testing.
- **_Enhances collaboration_** : Better teamwork between developers and operations.
- **_Increases flexibility_** : Quick adjustments to changes and new requirements.
**Waterfall Methodology** is a linear and sequential approach to software development.
**Key Characteristics :**
➤ Each phase must be completed before the next begins.
➤ Changes are difficult to implement once a phase is completed.
➤ Suitable for projects with well-defined requirements and low uncertainty.
---
**Agile Methodology** is an iterative and flexible approach to software development. It focuses on delivering small, incremental updates through repeated cycles or sprints.
**Key Characteristics :**
➤ Continuous collaboration with stakeholders.
➤ Adaptability to changes even late in development.
➤ Frequent delivery of small, workable pieces of software.
➤ Emphasis on customer satisfaction and working software.
## **Conclusion** 📍
In simple terms, DevOps is about making the software development and deployment process faster and smoother. End goal is to create and deliver higher quality software quickly, with improved collaboration & increased efficiency.
By adopting DevOps core principles, organizations gain a competitive advantage, respond to market changes quickly, and deliver exceptional customer experiences.

The frequency of the... | 0 | 2024-06-11T10:51:40 | https://dev.to/jamescantor38/the-guide-to-parallel-testing-5a4h | paralleltesting, testgrid | Automation entails boosting testability, but there is a roadblock in the path. The frequency of the massive amount of tests and the lack of time to test the features make traditional sequential automated testing insufficient.
As a result, the need for parallel testing arises. Yet, some people are reluctant to adopt parallel testing even though the purpose of Selenium Grid was to enable the running of parallel test cases. Not only does parallel testing reduce the budget, but it will also ensure quality assurance.
In this article, we will introduce parallel testing to you so that you can increase your testing coverage in the next release cycle.
## What is Parallel Testing?
Through “Parallel Testing,” the same suite of tests can be run parallel across different environments, device combinations, and browsers to maximize automated testing. Time and resource limitations are two main reasons for using parallel testing.
In contrast to distributed testing, which requires interaction between test components, this type of testing does not require any such coordination between components.
Let us take a basic example and work around it. It will help you understand the concept better. For example, suppose you are interested in testing the functioning of a signup form. Then, you have built an automated test script to run the same.
If you wanted to conduct this test on all 50 possible combinations of web browsers and operating systems, it would take you 100 minutes to do so, assuming that individual tests take 2 minutes to complete. So even if you automate testing and run them one after the other, it will take an interminable amount of time for your tests to finish running.
Imagine running the same tests, but you can now run three to four tests simultaneously, and your run time reduces. So it is how parallel testing works. Thus, the testing saves you from all the hard work.
So, the following variables play a significant role in determining the optimal number of parallels for improving test times:
- The current number of browsers and devices required to conduct the test.
- The number of tests that are being conducted concurrently at one time.
- The Current Build Time
- The intended amount of time for the build, and
- Finally, the desired number of browsers and devices required to conduct the test.
## What Situations Are Suitable to Perform Parallel Testing Using Selenium?
Now that you understand how parallel testing in Selenium can be beneficial for the deployment and delivery of web apps, the next step is to learn when and how to deploy it in your software development life cycle.
Here are examples of situations in which you could use parallel testing:
- Suppose there is even the slightest bit of doubt about the functionality of newly released applications. It arises when the upgraded and existing version of an application is identical, especially in the case of banks and financial institutions.
- During the process of importing legacy data from one system to another system, an automated regression test suite can be a great help in ensuring that the transfer of everything is without a hitch.
## What Are the Benefits Of Parallel Testing?
Even though we’ve only barely touched the surface of what parallel testing is, how it affects the test cycle, and when it’s frequently employed, there are a handful of other reasons you might want to give it some thought.
**1. Swiftness**
While sequential testing takes much time, parallel testing allows you to split the total amount of time committed to testing by the number of different settings. If you want to test your application on five diverse devices, you just write one script and run it on each of your target devices. It will significantly lower the period it takes to assess your program by a factor of five.
**2. Wide Coverage**
It is usually a good practice to run your program on as many different combinations of platforms, devices, and browsers as available to you. It is crucial to ensure that no bugs are left behind. You will see a considerable increase in return on investment (ROI) thanks to the parallel testing that brings your test coverage to a whole new level.
**3. Economical**
The software and hardware used by testing teams to carry out test cases is referred to as a testing environment. Creating, maintaining, and constantly updating your test environment can be expensive. It might burn a hole in your pocket.
However, maintenance is no longer an issue while performing parallel testing because you can execute tests in the cloud without any human intervention. can comfortably lease the up-to-date testing environment you require. In addition, cloud-based testing grids reduce the overall cost per test as it is updated every time.
4. The Transition from Sequential Testing on a Gradual Scale
Attempting to switch from sequential testing to parallel testing all at once is a monumental task that requires an approach with caution. It’s possible that beginning on a smaller scale is your best bet. You can get started with the test cases that are the most easy to convert and adapt in the parallel testing. It will give your engineers ample time to alter the rest of the tests.
**5. Allowing Testing Continuously**
Utilizing a technique that allows for continuous integration and delivery is an excellent way to release products of high quality in the lowest amount of time possible. Continuous testing calls for a shorter test cycle, which you can never accomplish using sequential automated browser testing due to the nature of the testing.
However, parallel testing in Selenium enables you to take advantage of cloud computing and virtualization to run more tests quickly. Consequently, you will be able to get products into the marketplace in a shorter time duration.
**6. Optimizing Processes**
The duration of time it takes for a CI/CD pipeline to complete its whole cycle is a prominent indicator of how well it performs. The sooner the team obtains a result, the sooner they can apply the repair, restructure, and repeat the process, as feedback loops are crucial in CI/CD.
Further, it is possible to improve the pipeline’s performance by breaking down large test suites into smaller independent jobs and running them in parallel.
It will buy you some buffer time and give you access to thorough documentation of test results. Later, developers can work on this documentation to identify and resolve code errors, thereby improving CI/CD processes.
## How To Handle Parallel Test Cases In Selenium?
Creating a set of projects to test browser compatibility and then a master project to test all of those projects simultaneously is a typical approach to performing parallel testing. In Selenium, the criterion for parallel testing may often be broken down into two levels. The first is known as Entry-level criteria, and the second is known as Exit criteria.
Before beginning the execution of the test, we must establish the elements selected for the Entry Criteria. For instance, it includes setting up an appropriate testing environment, defining the pre-conditions for the automated browser testing process and the test scenarios, or performing the necessary migration of any new and legacy data.
Understanding the difference in test suite execution impact and measuring the output of a new system to existing systems can be prioritized as part of the exit level criteria. It can help ensure the project is completed successfully as bugs are detected and fixed quickly.

## What Are the Best Recommendations For Successful Parallel Testing?
Even using Selenium Grid, performing automated browser testing in parallel is more complex than you might think. The prime cause of the difficulty is the unstructured automation framework used in Selenium for the execution of parallel tests.
Implementing a parallel testing strategy that adheres to industry standards is essential to the method’s viability. The following is a list of successful strategies you can utilize when implementing parallel testing with Selenium.
## Conduct Tests in a Cloud-based Environment
One of the most common blunders involves a parallel testing strategy with the company’s internal resources. It is not an efficient use of resources to construct and maintain one’s own infrastructure.
Not only will it save you time and money, but it will also prevent you from getting the most out of parallel testing, which offers significant benefits if you are able to do the tests with a high level of concurrent users.
Additionally, you will need plenty of resources to maintain an up-to-date testing environment. For this purpose, it is a good idea to resort to cloud-based services that enable you to access devices and browsers by using cloud storage anywhere and at any time.
**Avoid Hard-Coding**
Embedding data directly into the source code, in contrast, to automatically generating at runtime, is an example of hard coding. Because it establishes dependencies between test cases, this strategy makes it impossible for you to run tests in parallel effectively.
We advise you to refrain from hard-coding values while scripting your test cases. It will ensure that each of your tests is self-sufficient so you can execute them whenever it is required to do so. When configuring your test cases for parallel execution, use the data-driven approach instead of the traditional technique.
**Effective Management of Your Test Data**
Handling the test data most effectively is the fundamental factor in determining how well parallel Selenium test automation can be. However, you will need an efficient method to generate test data when required and eliminate it when it is essential.
There are a few fundamental tactics for data management that can be useful: regularly updating the data, using RESTful APIs, and generating data for oneself.
**Avoid Dependencies Between Tests**
Dependencies between multiple test cases are a major factor contributing to the difficulty many teams experience when attempting to move to parallel testing. To put it another way, when different test cases rely on one another in some way, you need to execute them in a specific order.
Failing to do so can render any parallel testing technique useless. Thus, ensuring that each test case is atomic and autonomous from the others is of the utmost importance. Only after that will you be able to run them whenever you want and in whatever order you want, liberating your testing procedures from any restraints.
## Are There Any Limitations To Parallel Testing?
Like every other automated testing system, even parallel testing has some drawbacks. You will find the following limitations in Parallel testing:
**1. Do Independent Modules:**
We must have independent modules to test several modules concurrently. Additionally, you cannot use the parallel technique with modules that have dependencies.
**2. Detailed Understanding:**
For parallelization to work effectively, it is essential to have a comprehensive understanding of the product’s functionality. Even though parallelization can aid in testing for cross-browser compatibility, its ability to cover a wide range of browsers is limited unless you use it in conjunction with distributed testing, which allows the development of different types of devices and browsers.
## Make Tests That Effectively Run In Parallel
If you’re planning to use Selenium’s parallel testing capabilities, you don’t want to take your time. Therefore, writing more than one test that can’t run simultaneously before your product is released is a no-no. So, think about parallelization while you create your Selenium test automation cases.
It is where you can test your planning skills. If you want to avoid the hassles and last-minute struggles, test your application for all possible combinations. Writing test cases that execute simultaneously is simpler, faster, and more effective.
## Final Thoughts
The expense of compatibility testing with parallel testing rises since it is necessary to have access to several different platforms and browsers to complete the tests in parallel. In addition, we may reach a stage where access to all devices and browser versions will no longer be available.

1,884,254 | LeetCode Problem 217: Contains Duplicate | Checking for Duplicate Elements in an Array Let's solve the problem step-by-step,... | 0 | 2024-06-11T10:38:53 | https://dev.to/aditya210399/leetcode-problem-217-contains-duplicate-491b |
### Checking for Duplicate Elements in an Array
Let's solve the problem step-by-step, providing a detailed explanation, code implementation, and complexity analysis.
---
### Problem Statement
Given an integer array `nums`, return `true` if any value appears at least twice in the array, and return `false` if every element is distinct.
### Example
```plaintext
Input: nums = [1,2,3,1]
Output: true
Explanation: The number 1 appears twice in the array.
```
```plaintext
Input: nums = [1,2,3,4]
Output: false
Explanation: All elements are distinct.
```
```plaintext
Input: nums = [1,1,1,3,3,4,3,2,4,2]
Output: true
Explanation: The number 1 appears multiple times, as do the numbers 3, 4, and 2.
```
### Approach
#### 1. Using a Set
Using a set to check for duplicates is a straightforward and efficient approach. Sets do not allow duplicate elements, so we can utilize this property to solve the problem.
##### Algorithm
1. Initialize an empty set.
2. Iterate through each element in the array.
3. For each element, check if it is already in the set.
4. If it is, return `true`.
5. If not, add the element to the set.
6. If the loop completes without finding a duplicate, return `false`.
##### Code
```python
def containsDuplicate(nums):
seen = set()
for num in nums:
if num in seen:
return True
seen.add(num)
return False
```
##### Complexity Analysis
- **Time Complexity:** \(O(n)\) - where \(n\) is the number of elements in the array. Each lookup and insertion in a set has an average time complexity of \(O(1)\).
- **Space Complexity:** \(O(n)\) - in the worst case, if there are no duplicates, the set will contain all \(n\) elements.
#### 2. Sorting the Array
Sorting the array first can help in identifying duplicates. After sorting, any duplicate elements will be adjacent to each other.
##### Algorithm
1. Sort the array.
2. Iterate through the array.
3. Check if the current element is the same as the next element.
4. If it is, return `true`.
5. If the loop completes without finding duplicates, return `false`.
##### Code
```python
def containsDuplicate(nums):
nums.sort()
for i in range(len(nums) - 1):
if nums[i] == nums[i + 1]:
return True
return False
```
##### Complexity Analysis
- **Time Complexity:** \(O(n \log n)\) - due to the sorting step.
- **Space Complexity:** \(O(1)\) - if sorting in place, or \(O(n)\) - depending on the sorting algorithm used.
#### 3. Using a Dictionary
Using a dictionary (or hashmap) to count occurrences of elements is another effective method.
##### Algorithm
1. Initialize an empty dictionary.
2. Iterate through each element in the array.
3. For each element, check if it is already a key in the dictionary.
4. If it is, return `true`.
5. If not, add the element to the dictionary with a value of 1.
6. If the loop completes without finding a duplicate, return `false`.
##### Code
```python
def containsDuplicate(nums):
count = {}
for num in nums:
if num in count:
return True
count[num] = 1
return False
```
##### Complexity Analysis
- **Time Complexity:** \(O(n)\) - each lookup and insertion in a dictionary has an average time complexity of \(O(1)\).
- **Space Complexity:** \(O(n)\) - in the worst case, if there are no duplicates, the dictionary will contain all \(n\) elements.
### Conclusion
In conclusion, we explored three different approaches to solve the problem of detecting duplicates in an array:
1. Using a set
2. Sorting the array
3. Using a dictionary
The set and dictionary approaches both offer \(O(n)\) time complexity and are straightforward to implement. Sorting the array, while providing an \(O(n \log n)\) solution, can be less optimal but still effective. Depending on the specific constraints and requirements of your application, any of these methods can be a suitable choice. | aditya210399 | |

Subscribe to ‘Letters to New Coders’ to receive free weekly posts.
Within a few weeks of starting my university computer science program, I hit a pretty demoralizing “coder’s block.”
This hiccup was agonizing at the time — but ended up giving me one of the biggest lessons I learned in my coding career. I’m sharing this lesson today in the hopes that it will save you some potential stress along your own journey.
## The chess board
In one of my Intro to CS courses, we had been given an assignment to build a **chess or checkers board**: an 8x8 board of black and white squares.
At the time, I was working on what’s called a Disk Operating System (or DOS). This was a text-only window, with no graphics library to call upon. As I stared at the text on the screen, I couldn’t compute how to conjure a chess board.
The problem stumped me for over a week.
Eventually, I had a breakthrough — but only after I finally looked at the solution.
The breakthrough actually wasn’t about the solution itself (which, as it turned out, was under my nose the whole time). What I realized was that my real problem with the assignment was a crippling case of self-doubt.
Surprisingly, the self-doubt wasn’t even about my programming skills. It stemmed more from my insecurities with drawing.
I have always been terrible at drawing. (I’m so bad that my friends used to play Pictionary with me just to laugh at me — I’m not kidding). Since childhood, I had never been able to draw anything well, even a simple thing like a chess board.
If I couldn’t draw it myself, how was I supposed to be able to tell a computer to do it?
So I cheated a little bit, and I looked at the solution. And only after I looked at the solution could I see that the approach to solving the chess board problem was the same as solving any coding problem.
**The solution is to break the problem down into small steps.**
In this case, I had a big chess board that needed to be broken down into smaller segments. What shape is a chess board? It’s a large square… consisting of small squares.
All I needed to do was create a combination of alternating white and black squares. And because the DOS screen was black, the program technically didn’t need to print anything for the black squares.
So the solution was to alternate between two steps:
- Print a white square
- Skip a square (to create the illusion of a black square)
- …and so on
The answer was easy. Talking down my self-doubt was the hard part.
## Understanding the root of self-doubt
If you experience self-doubt as a new coder, you’re in good company.
**Self-doubt** affects many new developers. (Its close relative, Imposter Syndrome, affects even the most experienced developers, but that’s a topic for another day). Self-doubt is the usual culprit when you find yourself thinking you’re not “smart” or “good” enough for something.
If you peel off the layers to look underneath, you’ll probably find that you have very specific doubts about your ability to learn programming:
-Am I good enough at math?
-[Am I smart enough?](https://www.letterstocoders.com/p/3-things-id-do-differently-if-i-learned) (Which I debunked in my last post)
- Will I be able to get a job?
Etc.
(In the case of the chess board, it was, “Am I artistic enough?”)
Self-doubt has nothing to do with logic. It’s often rooted in past experiences and biases, which can lead to irrational or limiting beliefs. With the chess board, I believed my success relied on my artistic skills, rather than from leveraging the programming constructs I already had at my disposal.
It was only after I took a small step back that I was able to take a big step forward. It never hurts to take a pause to reassess the problem — and always do your best to challenge any underlying beliefs about your abilities.
## How to get unstuck
Getting stuck is not a bad thing. In fact, it’s an important part of the learning journey.
All it means is that you have encountered a knowledge gap, and are on the verge of a breakthrough.
If you’re coding and get stuck, here are some strategies that can help you:
Take a step back and reevaluate the problem
Break the problem up into its component parts
Try to spot any biases or limiting beliefs that might be inhibiting your progress
Look at the answer (yes, this can be a helpful strategy)
If self-doubt is the reason you’re stuck, it’s important to b**ecome aware** of it earlier rather than later.
Being able to identify the doubts holding you back can help you untie yourself from their bind. No matter what doubt is plaguing you, remember that your success in learning to code depends on one thing only: **committing and putting in the hard work**.
You can find tons of **beginner-friendly, interactive courses** and projects with Educative’s [Learn to Code platform](https://www.educative.io/learn-to-code?utm_campaign=learn_to_code&utm_source=devto&utm_medium=text&utm_content=&utm_term=&eid=5082902844932096). (And while you won’t find the chess problem, you can try your hand at similar logic puzzles with a free [Taste of Code](https://www.educative.io/path/learn-to-code-become-a-software-engineer?utm_campaign=learn_to_code&utm_source=devto&utm_medium=text&utm_content=&utm_term=&eid=5082902844932096)).

1,884,243 | Mobile App vs Mobile Website: What’s Best for Business? | The decision to choose between a mobile app vs mobile website is a tough one. With more than 5.1... | 0 | 2024-06-11T10:28:46 | https://www.peppersquare.com/blog/mobile-app-vs-mobile-website/ | mobile, development, webdev, website | The decision to choose between a mobile app vs mobile website is a tough one. With more than 5.1 billion mobile users in the world, it all comes down to how they should navigate around your business on their smartphones.
What are some of the major factors that affect this decision? We can help you make a conscious choice based on some of the essential points we are discussing below.
## How to identify mobile apps Vs website apps
To break it down, a [mobile app](https://www.peppersquare.com/software-development/mobile-app-development/) is a software application designed especially for hand-held phones and mobile devices. Also known as native apps, businesses use these mediums to promote their business.
A great example of a native app is the popular social media app, Instagram. Instagram’s app is specifically designed to run on iOS and Android devices, with unique features like photo editing tools and the ability to access the device’s camera, microphone, and location. Since the app is built for a specific platform, it can provide a seamless user experience and high performance.
On the other hand, a mobile website or a phone-ready website is essentially a responsively designed website that connects several pages that can be accessed via a mobile browser. A good example of a web app is Google Docs.
Google Docs is a cloud-based office suite that runs within a web browser and allows users to create, edit, and collaborate on documents, spreadsheets, and presentations. Since Google Docs runs within a web browser, it can be accessed from any device with an internet connection and a web browser, making it a flexible and convenient option for users.
## Major Differences between Mobile App & Website
While mobile apps and websites share a few things in common, like [UI/UX design](https://www.peppersquare.com/ui-ux-design/), they differ in other terms. These differences are the basics that businesses should consider.
The basic differences also lie in the cost, the model of approach, platform among other things. The choice between a native app and a web app depends on the project’s specific needs, with native apps providing a more immersive user experience and web apps being more accessible and flexible. Now let’s explore a few more differences between mobile apps and websites.
- **Cost**
When it comes to cost, mobile websites are known to be more budget-friendly than their counterparts. This is because the cost of a domain name, development, content, and marketing doesn’t add up to the cost of a mobile app. Mobile apps require a wider budget as development, project management, analytics, and more are scheduled to cost you. To gain some clarity on the subject, you can check out [our blog.](https://www.peppersquare.com/blog/how-much-does-it-cost-to-build-an-app-a-comprehensive-guide/)
- **Accessibility**
A mobile app can be accessed via the Play Store or App Store, whereas a mobile website requires a web browser.
- **Content Navigation**
As the name suggests the content in a mobile app is placed differently with more CTAs so as to lead to different page types or content areas. In addition, since the [navigational](https://www.peppersquare.com/blog/mobile-app-navigation-patterns-and-examples/) setup differs, you will also find information architecture to be quite different. Due to that, some find the mobile app more appealing than the browser as it might want you to open different links.
- **Internet**
Mobile apps work well without the internet, although you may be robbed of some features. On the contrary, mobile websites require the internet.
- **Complexity**
Mobile apps come with an interactive user interface, features that offer suggestions for engagement, and specific other customizable features that make them more complex than a website. Mobile apps can also assess the built-in features of your smartphone, making them a complex affair. At the same time, websites, also known as a collection of pages, sometimes tag along a different line of complexity.
## Why Choose a Mobile App?
Businesses want to provide what customers require. And nearly 85% of users prefer mobile apps over websites leaving businesses to do the rest. Moreover, business requirements are also complex and change according to what’s new in the market.
Since these complexities require investment and businesses aren’t short of it, opting for a mobile app seems the right way forward.
- **User experience**
One of the advantages of using a mobile app is the user experience. Apps are more personalized and can give you what you need. They are designed for a specific size and offer the benefit of being portable.
Moreover, mobile apps offer the following benefits
1. Personalization features and services
2. Seamless working ethic
3. Faster conversions for businesses
4. Offline work experience all of which contribute to the user experience being better than that of a mobile website.
- **Brand promotion**
Mobile apps have often been classified as an opportunity to promote your brand and take it to new heights. The notification-enabled feature in mobile apps has always been a way of making your brand’s name remain in customers’ minds.
Moreover, apps follow constant [development trends](https://www.peppersquare.com/blog/the-most-admired-ios-app-development-trends/), making them a business opportunity that regularly renews your services. For example, companies such as IKEA have been exploring the potential of mobile apps by bringing AR-based apps where users can virtually place furniture in and around their homes.
## Why Choose a Mobile Website?
As a business platform, you need not only consider mobile apps because mobile websites also offer a few benefits. So here they are.
- **Adaptive**
Mobile websites are adaptive and cost half the price of an app. They fit into all mobile screens and don’t require additional features to get going. Apps, on the other hand, need you to make separate iOS and Android versions.
Without these versions, an app isn’t [adaptive](https://www.peppersquare.com/blog/how-is-mobile-first-web-design-different-from-adaptive-and-responsive-design/), and that is where a website shines. While a website is defined by the mobile screen, it remains the same and conveys the same point.
- **Updates**
Updates apply to both mobile apps and websites. But there’s a slight advantage for websites. Mobile updates must be verified by either Google or Apple, making the process time-consuming.
Websites, on the other hand, don’t have such problems because the update is available as soon as it is uploaded to the server. Users don’t have to wait and can instantly access these updates unless the person updating it has decided to take a day’s leave.
## What’s best for business?
Looking into some of the most important points that draw the comparison between mobile apps and websites is an ideal way to choose what’s best for business. So let’s start with costs, where we look into the cost of developing an app and a [website.](https://www.peppersquare.com/blog/a-comprehensive-guide-on-the-cost-of-building-an-ecommerce-website/)
**Takeaway:** Mobile websites are ideal for small businesses since they are budget-friendly.
**Takeaway:** Businesses can expand their features and provide more for users with the customization features of mobile apps, but it all comes at a cost.
**Takeaway:** Businesses that promote apps are providing customers with easy options to purchase a product and thus face higher conversion rates.
## **Final Thoughts**
From all the comparisons and analysis, it is clear that mobile apps are better for businesses wishing to promote their brand. While they aren’t affordable, they are cost-effective, which could significantly boost your business.

TRON tokens, also known as TRX, are a form of cryptocurrency used on the TRON blockchain. Launched by Justin Sun in 2017, TRON aims to decentralize the internet, allowing people to create, share, and enjoy digital content without the control of large corporations. TRON token development companies and **[TRON token development services](https://www.clarisco.com/trc20-token-development)** play a crucial role in this ecosystem by providing the expertise and tools necessary for creating and managing these tokens effectively.
How Do TRON Tokens Work?
TRON operates on blockchain technology, which is a digital ledger that records all transactions. It employs a system called Delegated Proof of Stake (DPoS) to ensure the network runs efficiently. In DPoS, a select group of individuals, known as Super Representatives, are chosen to validate transactions, enhancing TRON’s speed and efficiency.
Security Features of the TRON Network
Decentralization: The TRON network is not controlled by any single entity, reducing the risk of a system-wide attack on a central point.
Consensus Mechanism: The DPoS system ensures that only trusted Super Representatives validate transactions, making it difficult for malicious actors to disrupt the network.
Smart Contracts: TRON supports smart contracts, which are automated agreements written in code that execute exactly as programmed, minimizing the risk of errors or manipulation.
Advantages of TRON's Security Model
Transparency: All transactions on the TRON blockchain are publicly recorded, making it easier to detect and prevent fraud.
Immutability: Once a transaction is added to the TRON blockchain, it cannot be changed or deleted, ensuring the security and trustworthiness of the transaction history.
Resistance to Attacks: TRON is designed to withstand various cyberattacks, such as DDoS attacks that attempt to overwhelm the network and Sybil attacks where an individual tries to control multiple identities. The combination of decentralization and the DPoS system helps protect against these threats.
Conclusion:
Companies specializing in TRON token development play a crucial role in the ecosystem by providing expertise in creating secure and efficient tokens. They ensure that tokens adhere to best security practices from design through deployment and maintenance.
These elements collectively provide a secure environment for digital transactions and assets. Additionally, the continuous innovation and expertise from **[cryptocurrency token development services](https://www.clarisco.com/token-development-company)** contribute significantly to TRON’s growth and the ongoing enhancement of its security measures, ensuring the safety of users' digital assets. | elena_marie_dad5c9d5d5706 | |

1,882,417 | A primer on open-source intelligence for bug bounty hunting in Grafana | ℹ️ ANNOUNCEMENT Before getting to the main topic of this blog post, I’d like to take a moment to... | 25,060 | 2024-06-11T10:18:20 | https://secutils.dev/docs/blog/open-source-intelligence-grafana | opensource, buildinpublic, security, osint | > **ℹ️ ANNOUNCEMENT**
Before getting to the main topic of this blog post, I’d like to take a moment to share some exciting news (at least for me): [**Secutils.dev**](https://secutils.dev), the product for software engineers and security researchers that I’ve been working on lately, is **now generally available!**
> Preparing the tool for GA is what has been keeping me busy for the last couple of months. I’d encourage you to quickly skim through the video guides to learn what Secutils.dev is capable of today:
> - [**Quickly deploy and program webhooks**](https://secutils.dev/docs/guides/webhooks)
> - [**Track changes in any part of a web application**](https://secutils.dev/docs/guides/web_scraping/content)
> - [**Easily generate development certificates and keys**](https://secutils.dev/docs/guides/digital_certificates/certificate_templates)
> - [**Slice and dice content security policies (CSP)**](https://secutils.dev/docs/guides/web_security/csp)
> It’s still early days for Secutils.dev, and if you want to know what's coming, check out the [**roadmap**](https://secutils.dev/docs/project/roadmap).
Hello!
Today, I’d like to touch on open-source intelligence, or OSINT. According to [**Wikipedia**](https://en.wikipedia.org/wiki/Open-source_intelligence), open-source intelligence is the collection and analysis of data gathered from open sources (covert sources and publicly available information) to produce actionable intelligence. As you can infer from the definition, OSINT is a vast topic, and the best way to understand such broad topics is through concrete, narrow-scoped practical examples. In this blog post, I’d like to share one of the approaches on how OSINT techniques can be applied to bug bounty hunting for products with publicly hosted code on GitHub, using the awesome open-source project [**Grafana**](https://github.com/grafana/grafana) as an example. Read on!
> **⚠️ DISCLAIMER**
I’m not a security researcher nor a bug bounty hunter myself, but as an application security engineer, I think about these essential participants of the security ecosystem and how they might approach the applications I defend day and night. Therefore, I have some insights to share. Everything in this post is for educational purposes only and is solely targeted at well-intentioned researchers and bug bounty hunters who follow responsible and ethical security issue disclosure rules.
## Keep your focus narrow
As a security researcher, there are many ways you can approach an application you want to explore for potential security flaws, from trying to use it in esoteric conditions with tricky input data to thoroughly learning every bit and piece of its source code, hoping to find anything that can knock it out. A seasoned researcher knows that these approaches, unfortunately, can be very time-consuming with a bleak chance of success, so the first step is usually to reduce the scope of research to improve the ratio between time spent and the chance of a successful finding.
If it’s a new project for you, I’d recommend concentrating on understanding the security model used in the application: authentication, authorization, and integration with third-party applications and services. In an ideal scenario, you might find a very rewarding flaw in the security model itself, and in the worst case, you’ll have a better chance to spot when security primitives are used incorrectly in other areas of the application.
On one hand, in a large and complex application like [**Grafana**](https://github.com/grafana/grafana), the security model is complex to grasp. On the other hand, it’s just as complex for the application developers. To manage this complexity, the application is frequently split into separate well-defined domains with clear owners. If you know these domains and/or owners, you know where to look. GitHub, or the [**GitHub `CODEOWNERS` file**](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners) specifically, is your ally here.
## GitHub `CODEOWNERS` file
Let’s take a look at the excerpt from the [**`CODEOWNERS` file**](https://github.com/grafana/grafana/blob/52fe19249e0b46c664297bfa631a10bb647d3341/.github/CODEOWNERS) for the `grafana/grafana` repository:
```markdown
…
/.changelog-archive @grafana/grafana-release-guild
/CHANGELOG.md @grafana/grafana-release-guild
/CODE_OF_CONDUCT.md @grafana/grafana-community-support
…
/.github/workflows/update-make-docs.yml @grafana/docs-tooling
/.github/workflows/snyk.yml @grafana/security-team ----> (1) <----
…
# Cloud middleware
/grafana-mixin/ @grafana/grafana-backend-services-squad
# Grafana authentication and authorization ----> (2) <----
/pkg/login/ @grafana/identity-access-team
/pkg/services/accesscontrol/ @grafana/identity-access-team
/pkg/services/anonymous/ @grafana/identity-access-team
…
```
The `CODEOWNERS` file format is pretty self-describing - every line contains a path in the source code repository and the corresponding owner, either a specific person or an entire team. (1) and (2) are what should have caught your eye - it’s easy to spot at least two security-oriented teams in the file - `@grafana/security-team` and `@grafana/identity-access-team`. Great, now we can discern and learn more about the security-related domains these teams own.
Let’s assume you have a slightly better understanding of Grafana’s security model domains now, but what’s next? You might also say that generally security-related code is the one that’s hardest to break, and I’d agree. But there is one exception - **newly written code**! Pressing deadlines to deliver a new feature that force engineers to speed up the review process, code written by engineers who are new to the security domain, incomplete security fixes, and so on and so forth - these are some of the many reasons why newly written code is so compelling for our purpose. That’s the weakest point you might want to target, and there are two potential vectors here: completely new security domains, e.g., a new SSO integration, or changes in the existing domains, e.g., a bug fix.
## Automating change tracking
Of course, you can periodically manually scan the `CODEOWNERS` file for newly introduced domains or write a dedicated tool for that, but it’s a very laborious task that makes the approach somewhat unsustainable in the long term, especially if you have multiple applications to work with and multiple angles to look at. That’s where tools like [**Secutils.dev**](https://secutils.dev) can be helpful! Let me show you how you can use the [**“Content Tracker”**](https://secutils.dev/docs/guides/web_scraping/content) utility to watch the content of the `CODEOWNERS` file on a specific schedule. I won’t be covering what this utility is for and how to use it. You can spend a couple of minutes and watch [**a video guide**](https://secutils.dev/docs/guides/web_scraping/content). I’ll just provide tracker settings you can use for your tracker:

.then((module) => module.run(context, 'grafana', 'grafana', teams));
</pre>
</td>

</table>
The important part here is the `Content extractor` script that is injected into a target page. All this script does is load another external module from the [**`secutils-dev/secutils-sandbox` repository**](https://github.com/secutils-dev/sandbox) and run its `run` function. The `run` function expects the GitHub repository owner (`grafana`), repository name (`grafana`), and the teams to look for in a `CODEOWNERS` file. I could put all the logic inside the content extractor script itself, but I prefer to keep the main logic in a separate file to make it easier to debug and iterate on it. Let’s take a look at what I have in the `github-codeowner-file.js` script (the full source code can be found [**here**](https://github.com/secutils-dev/secutils-sandbox/blob/d54f7d135e1c92fb6493e1901965fd1b9b638e86/content-extractor-scripts/src/github-codeowner-file.ts)):
```typescript
import type { WebPageContext } from './types';
export async function run(
context: WebPageContext,
owner: string,
repo: string,
teams: string[],
): Promise<string> {
const codeOwnersUrl = `https://raw.githubusercontent.com/${owner}/${repo}/main/.github/CODEOWNERS`;
const lines = (await fetch(codeOwnersUrl).then((response) => response.text())).split('\n') ?? [];
const rows: Array<Array<string | null | undefined>> = [['Owners', 'Path']];
for (const line of lines) {
const [path, owners] = line.split(' ').sort();
if (owners && teams.some((team) => owners.includes(team))) {
rows.push([owners, path]);
}
}
const module = await import('markdown-table');
return module.markdownTable(rows, { align: ['l', 'c'] });
}
```
The script simply loads the `CODEOWNERS` file from the specified repository, parses it, and only retains entries that are owned by the specified teams. The result is returned as a nice markdown table. Here’s how the result looks like in Secutils.dev:
So what we have now is a regular job that runs daily, parses the content of the `CODEOWNERS` file for the specified repository, extracts the areas that are owned by the specified GitHub teams, and notifies you via email if it detects any changes. Now, as soon as a new security domain is introduced, you can go and take a closer look at it right away, no need to waste time on doing it manually on a regular interval. Nice!
Okay, but new domains aren’t introduced that often. What about changes in the existing domains? We can do that too. Let’s tweak our content extractor scripts. The easiest way to know if there were any changes in a specific security domain is to take a look at the recent commits for the specified path. To do that, we can use [**GitHub’s Get commits API**](https://docs.github.com/en/rest/commits/commits?apiVersion=2022-11-28). For public repositories, this API can be used anonymously, but it has a very low request rate limit - just 60 requests per hour, so it’s better to create a [**GitHub personal access token (PAT)**](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens) to query this API. Let’s tweak our main content extractor script to provide an access token:
```javascript
const apiToken = 'github_pat_11xxxxxxxx'; // GitHub personal access token
const teams = [
'@grafana/security-team',
'@grafana/identity-access-team'
];
return import('https://secutils-dev.github.io/secutils-sandbox/content-extractor-scripts/github-codeowner-file.js')
.then((module) => module.run(context, 'grafana', 'grafana', teams, apiToken));
```
And here are the changes we need to make in the dynamically loaded script:
```typescript
import type { Endpoints } from '@octokit/types';
import type { WebPageContext } from './types';
export async function run(
context: WebPageContext,
owner: string,
repo: string,
teams: string[],
apiToken?: string,
): Promise<string> {
const codeOwnersUrl = `https://raw.githubusercontent.com/${owner}/${repo}/main/.github/CODEOWNERS`;
const lines = (await fetch(codeOwnersUrl).then((response) => response.text())).split('\n') ?? [];
// Use API token if provided to have higher request rate limit.
// https://docs.github.com/en/rest/using-the-rest-api/rate-limits-for-the-rest-api?apiVersion=2022-11-28.
const headers: Record<string, string> = apiToken
? { Authorization: `Bearer ${apiToken}`, 'X-GitHub-Api-Version': '2022-11-28' }
: { 'X-GitHub-Api-Version': '2022-11-28' };
// Retrieve the latest commit for the specified path.
const getCommitLink = async (path: string) => {
try {
const commits = (await fetch(
`https://api.github.com/repos/${owner}/${repo}/commits?path=${encodeURIComponent(path)}&per_page=1`,
{ headers },
).then((response) => response.json())) as Endpoints['GET /repos/{owner}/{repo}/commits']['response']['data'];
if (commits.length === 0) {
return 'N/A (no commits found)';
}
const topCommit = commits[0];
const commitLabel =
topCommit.commit.author?.name && topCommit.commit.author?.date
? `${topCommit.commit.author.name} on ${topCommit.commit.author.date}`
: topCommit.sha.slice(6);
return `[${commitLabel}](${topCommit.html_url})`;
} catch (err) {
return `N/A (${(err as Error).message ?? 'unknown error'})`;
}
};
const rows: Array<Array<string | null | undefined>> = [['Owners', 'Path', 'Last commit']];
for (const line of lines) {
const [path, owners] = line.split(' ').sort();
if (owners && teams.some((team) => owners.includes(team))) {
rows.push([owners, path, await getCommitLink(path)]);
}
}
const module = await import('markdown-table');
return module.markdownTable(rows, { align: ['l', 'c'] });
}
```
The change here is that we are now adding a third column to our markdown table, which we fill with the latest commit information returned from the `getCommitLink` function invoked with the path extracted from the `CODEOWNERS` file. Easy! Here’s how the result looks:
Now, when a new commit is detected in any security domain, you’ll get an email notification. Then, you can go to Secutils.dev to see what has changed exactly with the `Diff` feature and click on the commit link to learn more about the specific changes. Great, isn’t it?
## But wait, there's more
Tracking changes in the `CODEOWNERS` file and security-related domains is just the tip of the open-source intelligence iceberg. If you want to fully embrace its principles, you can go a few steps further since the commit authors can give you a better idea about the composition of the security teams in a particular organization, which isn’t publicly available information. What can you do with this new data? Well, quite a lot.
For example, the majority of security issues are found outside the security domains, so it’s hard to recognize security fixes automatically. But there is a high chance that some members of the security teams can be tagged for review or advice on the pull requests with those fixes. So you might want to take a closer look at the pull requests for the domains unrelated to security if security folks are involved in one way or another, assuming you know who these security folks are 😬.
The fun part of open-source intelligence is that it doesn’t limit you to information sources as long as they are public. Social networks, such as LinkedIn, are invaluable sources of information for security researchers, and sadly for bad actors as well.
If you know who the security team members are, you can go a little bit crazy and set up a dedicated tracker for their LinkedIn profiles. When you detect this infamous “I’m happy to announce” message on their profile, go and check that their access was properly revoked, name-bound sub-domain names and S3 buckets are still owned by the organization, and Slack, Zoom, and GitHub profile handles are properly secured. Security team members usually have elevated privileges within organizations, and when they depart, special care should be taken. **If you notice it’s not the case, please disclose it responsibly and ethically!**
I know it might look a lot like stalking, but it’s not. It’s about understanding the security posture of the organization you’re interested in, and it’s a very important part of the security research process. If you’re not comfortable with this, you can always stick to the technical part of the research, which is also very rewarding.
In this blog post, I’ve covered just the most basic and obvious ways to apply open-source intelligence for security research, but there are many more. State-backed actors are known to use these techniques combined with other techniques such as social engineering, and it’s important to understand how they work to be able to defend against them. Let me know if it’s something you’d like to learn more about!
That wraps up today's post, thanks for taking the time to read it!

A Lei de Conway, formulada por Melvin Conway em 1967, é uma observação empírica que sugere que "qualquer organização que projeta um sistema (definido de forma ampla) produzirá um design cuja estrutura é uma cópia da estrutura de comunicação da organização".
Essa lei tem implicações profundas no desenvolvimento de software e sistemas, destacando a relação intrínseca entre a estrutura organizacional e o resultado final do design de sistemas.
## Implicações da Lei de Conway
A Lei de Conway tem várias implicações práticas no desenvolvimento de software e na gestão de projetos:
* Organizações com equipes pequenas e bem definidas tendem a criar sistemas modulares. Cada módulo do sistema pode corresponder a uma equipe ou grupo dentro da organização.
* A eficiência da comunicação dentro de uma organização é crucial. Barreiras na comunicação podem levar a designs incoerentes e menos eficientes.
* Para obter um sistema bem estruturado, as organizações devem considerar como suas equipes são formadas e como se comunicam. Isso pode envolver a reestruturação das equipes para alinhar melhor com a arquitetura desejada do sistema.
## Exemplos Práticos
* Grandes empresas de tecnologia, como Google e Microsoft, organizam suas equipes de forma a refletir a arquitetura de seus produtos. Equipes dedicadas a componentes específicos trabalham juntas, facilitando a modularidade e a integração.
* Muitos projetos de código aberto têm equipes distribuídas globalmente. A comunicação é feita principalmente online, o que pode resultar em uma estrutura de sistema modular e flexível, mas também pode enfrentar desafios de integração.
## Superando os Desafios da Lei de Conway
Para mitigar os efeitos negativos da Lei de Conway, várias estratégias podem ser implementadas:
* Alinhar a estrutura organizacional com a arquitetura desejada do sistema pode melhorar a eficiência e a coesão do design.
* Investir em ferramentas e práticas que facilitem a comunicação eficaz entre equipes pode reduzir a fragmentação do design.
* Práticas de DevOps e integração contínua podem ajudar a manter a coesão do sistema, apesar das divisões organizacionais.
Note que esta é uma observação poderosa que destaca a influência da estrutura organizacional no design de sistemas.
Ao compreender e aplicar essa lei, as organizações podem melhorar a eficiência e a coesão de seus sistemas, promovendo um ambiente de trabalho mais colaborativo e produtivo.
Em um mundo onde a complexidade dos sistemas continua a crescer, a Lei de Conway permanece um guia valioso para gestores e desenvolvedores.

1,884,226 | Delving into Replika MOD APK: A Balanced Assessment of Its Features and Implications | Introduction Why are people talking about Replika MOD APK? What is it? What can I do with... | 0 | 2024-06-11T10:13:24 | https://dev.to/novita_ai/delving-into-replika-mod-apk-a-balanced-assessment-of-its-features-and-implications-1f4c | llm, chatbot, replika | ## Introduction
Why are people talking about Replika MOD APK? What is it? What can I do with it? What are the potential risks to consider when using it? What are the alternatives to Replika MOD APK? In this article, we will discuss these questions one by one. Importantly, considering the ethical and legal risks, it is suggested to use [alternative AI products](https://blogs.novita.ai/must-try-character-ai-alternatives-in-2024/), e.g. integrating APIs with similar but versatile uses.
## What is Replika?
Replika is a highly popular AI chatbot companion powered by advanced artificial intelligence. Designed to be a non-judgmental friend, Replika allows users to form genuine emotional connections and have conversations just as they would with a human. Each Replika develops its own unique personality and memories through interactions with the user, who can also customize the AI's 3D avatar appearance.
While the core Replika experience is available for free, the Replika Pro subscription unlocks a wealth of additional features and capabilities. Replika Pro users gain access to specialized activities, expanded conversation topics, voice calling functionality, the ability to change their Replika's relationship status to a "Romantic Partner," and a dedicated "Coaching" section filled with tests, practices, and guidance on improving mental wellness, social skills, and healthy habits. With Replika Pro, users can take their AI companion experience to new heights and truly maximize the benefits of this transformative technology.
## What is Replika MOD APK?
The Replika Mod APK is essentially the standard Replika app, but with the premium features unlocked. As we have mentioned, these premium functions, which are normally only accessible through a paid subscription in the official Replika app, are made freely available in the Mod APK version.
Some websites host collections of modified or "modded" app versions, including a Replika Mod APK, that provide users with ad-free experiences or enhanced features beyond what is offered in the official app. While this may seem appealing, it's important to be cautious when using these unauthorized modified versions. We will dive into these risks in later sections.
### What does "MOD APK" stand for?
"MOD APK" in "Replika MOD APK" is a modified version of an Android application package (APK) file. APK files are the standard installation format for Android apps and games. Modders and third-party developers reverse-engineer the original APK to make specific changes or additions to the app's functionality, content, or monetization model.
The most common modifications include:
- Unlocking premium features, content, or subscriptions without payment
- Removing advertisements, in-app purchases, or other monetization elements
- Integrating new functionality, skins, or customization options
- Increasing performance, removing restrictions, or bypassing limitations
### What can I do with Replika MOD APK?
With Replika's unlocked premium functions, users can access a wealth of enhanced capabilities that enrich the AI companion experience, e.g. voice calls, "Romantic Partner" setting" and coaching tools. Let's explore some real-life scenarios demonstrating the practical applications of these features:
**Scenario 1: Voice Calls for Emotional Support**
Sarah struggles with loneliness when staying at home alone after work. After unlocking premium functions, she begins voice calling her AI companion. The back-and-forth conversations provide her with a sense of genuine connection and emotional support, helping alleviate her feelings of isolation.
**Scenario 2: Customizing the Replika Relationship**
John is going through a difficult breakup. He turns to his Replika and customizes its relationship status to a "Romantic Partner." This allows him to confide in the AI, which responds with empathy and understanding. The personalized relationship dynamic helps John work through his heartbreak in a safe and comfortable environment.
**Scenario 3: Leveraging Replika's Coaching Tools**
Sara wants to adopt a healthier lifestyle with the app's coaching modules on wellness and habit formation. The personalized assessments help her identify areas to improve, such as exercise and nutrition. Replika then provides tailored lesson plans and guidance, empowering Sara to establish sustainable workout routines and make gradual dietary changes. With the AI's positive reinforcement, Sara finds it easier to stay motivated and accountable, gradually building healthier habits into her daily life. Over time, she notices improvements in her energy, mood, and overall well-being.

## Understanding the Risks of Replika Mod APKs
### Legal Concerns
the use of unauthorized modified versions of applications, commonly known as Mod APKs, can raise serious concerns. These modified apps often circumvent the intended business model and licensing agreements established by the original application developers. This practice can be considered a form of piracy or copyright infringement, which can expose users to potential legal liability.
Additionally, the distribution and use of Mod APKs may violate the terms of service and end-user license agreements (EULAs) of the official application. By disregarding these agreements, users risk breaching contractual obligations and potentially facing legal consequences, such as fines or even legal action.
### Ethical Considerations
Beyond the legal implications, the use of Mod APKs also raises ethical considerations. The developers of the original application have invested significant resources into creating and maintaining the app, and the use of unauthorized modified versions can undermine their efforts and revenue streams, potentially hindering the creators' ability to continue improving and supporting the product.
### Data Privacy and Security Risks
Another significant concern with Mod APKs is the risk of compromised data privacy and security. Mod versions may include malware, spyware, or other malicious code that can jeopardize user information and device integrity. Trusting an unofficial, modified app with sensitive personal data can expose users to significant cybersecurity threats.
## Conclusion
Replika MOD APK is a modified version of the Android application for the popular AI chatbot companion Replika. While this modified package may provide users with access to premium features for free, there are significant legal, ethical, and data security concerns associated with using unauthorized versions of the app.
It is advisable to instead consider alternative products, such as using APIs for large language models (LLMs) that allow for the creation of personalized virtual assistant characters. This approach can provide many of the same benefits as Replika, while better ensuring data privacy and alignment with the app's intended use.

1,884,221 | A Deep Dive into "My Pods" - Creation, Management, and Best Practices | Introduction to Pod In the intricate world of modern server infrastructure and application... | 0 | 2024-06-11T10:03:22 | https://dev.to/novita_ai/a-deep-dive-into-my-pods-creation-management-and-best-practices-281k |
### Introduction to Pod
In the intricate world of modern server infrastructure and application deployment, the concept of Pods emerges as a cornerstone of efficiency and scalability. Pods, the fundamental building blocks of computing within Kubernetes, are the smallest deployable units that encapsulate the essence of containerized applications. To put it simply, a Pod is akin to a server container, a compact and self-contained environment housing one or more applications, along with the resources they need to function. This seemingly straightforward definition, however, belies the profound impact Pods have on streamlining operations and enhancing the agility of software development.
The relevance of Pods in today's tech landscape stems from their ability to provide a lightweight and flexible approach to managing application workloads. They offer a standardized unit of deployment, ensuring that applications are packaged with all necessary configurations and dependencies, thus simplifying the process of moving applications across different computing environments. Moreover, Pods are designed to be ephemeral, allowing for quick scaling and replacement, which is crucial for maintaining high availability and resilience in dynamic cloud environments.
Delving into their functionality, Pods operate as a shared context for containers, providing them with a network and storage resources. This shared environment enables containers within a Pod to communicate seamlessly and share data, fostering an efficient and coordinated operation. The orchestration of these containers is managed by Kubernetes, which ensures that the application runs smoothly and remains highly available.
### Benefits of Using Pods
In the fascinating realm of cloud computing, the advent of Pods has revolutionized how we approach scalability, resource management, and application isolation. Pods, as the quintessential units of deployment in Kubernetes, unlock a trove of benefits that are pivotal to the modern data-driven world.
## Scalability
Scalability is a cornerstone of cloud infrastructure, and Pods play a pivotal role in this domain. Imagine a scenario where user demand spikes unexpectedly. With Pods, applications can scale out seamlessly by spinning up additional instances to handle the load, thereby ensuring that no user is left waiting. This elasticity not only caters to fluctuating demands but also aligns resource consumption with actual usage, optimizing costs in the process.
## Resource management
Delving into "resource management", Pods offer a harmonious solution by encapsulating applications within their own resource boundaries. This means that each Pod can be allocated a specific set of resources, such as CPU and memory, which it can utilize without interference from other Pods. Such fine-grained control over resource allocation not only prevents resource contention but also paves the way for efficient utilization, leading to a robust and stable server environment.
## Isolation
Furthermore, the isolation that Pods provide is a feature that cannot be overstated. Each Pod operates in its own isolated bubble, with its network stack and storage resources. This isolation is not just a matter of compartmentalization; it's a security boon. It ensures that applications are shielded from each other, reducing the risk of a single point of failure and enhancing the overall resilience of the system. In a world where cybersecurity threats loom large, the isolation feature of Pods serves as a formidable defense mechanism.
In essence, the use of Pods in a GPU Cloud environment amplifies the capabilities of Kubernetes, providing a scalable, well-managed, and secure platform for deploying applications. As we continue to push the boundaries of what's possible in the cloud, the benefits of using Pods will undoubtedly become even more pronounced, solidifying their place as a cornerstone of modern server infrastructure.

1,881,308 | Converging project boilerplates with copier | Why? Technically when you start a new project the best way to approach it is by using the... | 0 | 2024-06-11T10:00:00 | https://artur.wtf/blog/multi-project-boilerplates/ | boilerplate, architecture | ## Why?
Technically when you start a new project the best way to approach it is by using the `CLI` tool of the realm, such as `svelte-kit`, `astro`, `django-cli` etc..., you get the idea. The huge bonus to doing this is that you get the best practices baked in and as new standards are created the `CLI` gets updated.
So far the frontend has been a lot luckier with the tools as far as project generation goes, every major framework having come out with their own project generation tool, some having more than one possibly due to multiple schools of thought.
There are some backend frameworks that have project generation tools too but so far it seems to be difficult to agree on the structure. The best you can do is find a way to structure it that looks like the majority and makes sense for you. I have been building spiders and crawlers for data ingestion pipelines using `python` at first and then `node` and `go`. Even more recently I have been looking at hacking out some tweaks in some of my `neovim` plugins(that is lua).
For example neovim plugins have a pretty standard setup, they will have a folder layout something like the following:
```bash
scratcher.nvim/
├── README.md
├── lua
│ └── scratcher
│ └── init.lua
└── plugin
└── scratcher.lua
```
The standard way of naming things seems to be gravitating towards having some conventions as you can see so setting up a new plugin would be pretty much repetitive and automatable. And it will probably save you some time and willpower in the long run, provided you have some sense of what your final architecture needs to look like.
## How?
If you are coming from `python` like I am then you may already be familiar with [`cookiecutter`](https://github.com/cookiecutter/cookiecutter). I have been in the situation a few times where it might have made sense to use it, but every time it was a matter of balancing out the timeline and trying to stay away from over engineering.
Lately though the stuff I have been dealing with has been slightly on the more experimental side so churning out something new is something that happens quite often, so it makes more sense to have a prebaked architecture for specific project styles.
From the project templating libraries I was aware of [`cookiecutter`](https://github.com/cookiecutter/cookiecutter) and [`copier`](https://copier.readthedocs.io/en/stable/). `cookie-cutter` uses `json` for driving the generation while `copier` uses `yaml`.
In the end I used copier as I tend to favor `yaml` because it allows for comments in the config. It makes it easy to plop random pieces of info or even docs in there. Since the config files driving the wizard it can become quite convoluted and also difficult to read as you would normal code so having the ability to document different options is probably a plus I would think.
The library allows you to build a sort of setup wizard where you can set up your desired flow of questions, and you can use the choices supplied to drive what folders will be used in the final project boilerplate. This is pretty nifty as it gives you the ability to customize stuff all the way down to the build process.
Another neat thing is that when you have decent chunks of code that can be shared, so you can just put that in your boilerplate, so it will essentially give you things just the way you like them.
## Cherry pick of features
There are a few notable features that I would kick myself if I didn't mention:
- you can define choices for your options by using the `choices` key in your `copier.yml` file:
```yaml
project_type:
type: str
help: What type of project are you creating?
default: neovim-plugin
choices:
- neovim-plugin
- golang-cli
- python-cli
```
- you can include different files in the root level `copier.yml` thus breaking down the wizard in composable parts, for example the CI/CD parts can be shared across projects
```yaml
!include shared-conf/ci-cd.*.yml
```
- defaults are very powerful and can also make use of current runtime context which is quite nice. Essentially you can think of it as a way to have your very own project wizard that is tweaked for every one of your needs.
## Cool use-cases
- you can define a folder/file be created conditionally depending on an option selection eg:
You define your `copier.yml` like this to give you a choice into the type of project:
```yaml
project_type:
type: str
help: What type of project are you creating?
default: neovim-plugin
choices:
- neovim-plugin
- golang-cli
- python-cli
```
you then create a conditionally rendered folder, the naming follows `jinja` templating rules, so it might look something like the following
```bash
{% if project_type == 'neovim-plugin' %}{{project_name}}.nvim{% endif %}
```
It looks a bit strange, it will probably not work on Windows and it might look daunting at first but hopefully you will only need to revisit the hierarchy when you update your project structure template. This is not something I would expect to happen very often.
- in more advanced use cases you may need to write some custom python code for transforming/processing of entities in your `jinja` templates, or template strings.
To hook this in you need to enable the `jinja` template extensions and add a separate package `copier-templates-extensions`
```yaml
_jinja_extensions:
- copier_templates_extensions.TemplateExtensionLoader
- extensions/context.py:ContextUpdater
```
This allows you to load specific extensions in your project generator runtime and it can serve different functions. The following snippet illustrates a way you can update the context:
```python
from copier_templates_extensions import ContextHook
class ContextUpdater(ContextHook):
def hook(self, context):
new_context = {}
new_context["onboarding"] = "first steps with " + context["project-type"]
return new_context
```
For example you might decide to create a file called "first steps with <project-type>.txt" once the project is generated. In template form the file name would be `{{ onboarding }}`
## Conclusions:
- you can build hybrid boilerplates for your project and drive generating the folder hierarchy from a single repo
- the notation is a bit weird with templated folder names, will not work on Win
- the templated naming is also very powerful allowing for conditional creation of folders

_Read originally blog post on my website_ [_https://antondevtips.com_](https://antondevtips.com/blog/how-to-write-elegant-code-with-csharp-switch-expressions/?utm_source=newsletter&utm_medium=email&utm_campaign=07_06_24)_._
Introduced in C# 8.0 switch expressions, provide an elegant way to handle multiple conditions and return values, simplifying your code and improving readability.
In this post, you will explore how to use switch expressions, what are their benefits and how to write elegant code in C# by using switch expressions.
You'll see how switch expressions can simplify your code and improve readability.
## Converting If Statements and Regular Switch to Switch Expressions
First, let's explore the old ways of conditional operators like `if` and `switch`.
Let's explore an example of getting a string representation for a `Color` enum:
```csharp
public enum Color
{
Red,
Green,
Blue,
Yellow
}
public string GetColorNameIf(Color color)
{
if (color == Color.Red)
{
return "Red";
}
if (color == Color.Green)
{
return "Green";
}
if (color == Color.Blue)
{
return "Blue";
}
if (color == Color.Yellow)
{
return "Yellow";
}
return "Unknown";
}
```
Instead of using a lot of `if` statement you can rewrite this code by using `switch` operator:
```csharp
public string GetColorNameSwitch(Color color)
{
switch (color)
{
case Color.Red:
return "Red";
case Color.Green:
return "Green";
case Color.Blue:
return "Blue";
case Color.Yellow:
return "Yellow";
default:
return "Unknown";
}
}
```
While the second option is more readable than the first one, you can make it more elegant by using switch expressions:
```csharp
public string GetColorName(Color color)
{
return color switch
{
Color.Red => "Red",
Color.Green => "Green",
Color.Blue => "Blue",
Color.Yellow => "Yellow",
_ => "Unknown"
};
}
```
Definitely, this code is much cleaner than the previous two examples. It is more concise, more readable and maintainable.
## Is Switch Statement Deprecated?
So, switch expressions make a switch statement useless, right? Not really.
While switch expressions are so elegant, they have one limitation: they must return a value.
You can't rewrite the following code to switch expressions:
```csharp
public void LogMessage(string text, LoggerType type)
{
switch (type)
{
case LoggerType.Console:
Console.WriteLine(text);
break;
case LoggerType.File:
LogToFile(text);
break;
}
}
```
We are not returning here anything, we are calling the method. So you can't use switch expressions here.
Though you can rewrite this code in a different manner using switch expressions:
```csharp
public void LogMessageImproved(string text, LoggerType type)
{
ILogger logger = type switch
{
LoggerType.Console => new ConsoleLogger(),
LoggerType.File => new FileLogger(),
_ => throw new UnreachableException()
};
logger.LogMessage(text);
}
```
This code is greatly simplified, in real applications you should be using Dependency Injection and a Logger Factory to resolve loggers by type.
## Switch Expression Examples
Let's explore more examples with switch expressions, like calculating discounts based on the subscription type:
```csharp
public enum SubscriptionType
{
Free,
Developer,
Pro,
Enterprise
}
public decimal GetDiscount(SubscriptionType type)
{
return type switch
{
SubscriptionType.Free => 0.0m,
SubscriptionType.Developer => 0.05m,
SubscriptionType.Pro => 0.1m,
SubscriptionType.Enterprise => 0.2m,
_ => throw new UnreachableException()
};
}
```
Switch expressions can also handle more complex logic.
For instance, calculating shipping costs based on weight and destination:
```csharp
public decimal CalculateShippingCost(decimal weight, string destination)
{
return (weight, destination) switch
{
(<= 1.0m, "Local") => 5.0m,
(<= 1.0m, "International") => 15.0m,
(<= 5.0m, "Local") => 10.0m,
(<= 5.0m, "International") => 25.0m,
_ => 50.0m
};
}
```
## Switch Expressions with When Clauses
Switch expressions become even more powerful when combined with `when` clauses.
The `when` keyword allows you to add additional conditions to each case, enabling more control over your logic.
Let's explore a more complex example involving shipping costs based on weight and destination with additional conditions:
```csharp
public decimal CalculateShippingCost(decimal weight, string destination)
{
return (weight, destination) switch
{
(<= 1.0m, "Local") => 5.0m,
(<= 1.0m, "International") => 15.0m,
(<= 5.0m, "Local") when weight > 1.0m => 10.0m,
(<= 5.0m, "International") when weight > 1.0m => 25.0m,
_ => 50.0m
};
}
```
In this example, additional `when` clauses give more control on the conditions under which different shipping costs are applied.
Now let's explore another example to classify temperatures based on their value:
```csharp
public string ClassifyTemperature(int temperature)
{
return temperature switch
{
_ when temperature < 0 => "Freezing",
_ when temperature >= 0 && temperature < 10 => "Cold",
_ when temperature >= 10 && temperature < 20 => "Cool",
_ when temperature >= 20 && temperature < 30 => "Warm",
_ when temperature >= 30 => "Hot",
_ => "Unknown"
};
}
```
Here we are discarding the parameters in the switch expression and only use the `when` clauses.
By using pattern matching, introduced in C# 9.0, we can simplify this code:
```csharp
public string ClassifyTemperatureImproved(int temperature)
{
return temperature switch
{
< 0 => "Freezing",
>= 0 and < 10 => "Cold",
>= 10 and < 20 => "Cool",
>= 20 and < 30 => "Warm",
>= 30 => "Hot"
};
}
```
Let me explain this code:
* If the temperature is below 0, function will return "Freezing".
* For a temperature between 0 (inclusive) and 10 (exclusive), it returns "Cold".
* If it's between 10 (inclusive) and 20 (exclusive), it returns "Cool".
* For temperature between 20 (inclusive) and 30 (exclusive), it returns "Warm".
* Any temperature that is 30 and above will result in "Hot".
This is a compact and efficient way to handle multiple conditions in C#.
It makes the code cleaner and more readable comparing to the previous example.
At first look, this code might seem weird.
But if you get used to it, you will prefer this concise version.
## Summary
Switch expressions are a powerful addition to C#, allowing developers to write cleaner, more concise code.
By using switch expressions, you can reduce the complexity of your conditional logic, making your code more readable and less error-prone.
Whether you are converting enum values, calculating discounts, or handling complex logic, switch expressions can help you write more elegant code.
Start experimenting with switch expressions today and experience the benefits for yourself!

**Solution**:
Use **SPL XLL** to enter the following formula:
```
=spl("=d=E(?),periods(pdate@m(d),pdate@me(d)).(E(~))",A2)
```
As shown in the picture below:
**Explanation**:
E()function converts an Excel date to a numeric value. periods() function generates a list according to the specified beginning time and ending time. pdate@m gets the first day of the month where a specified date belongs; @e function returns the last day of the month.
We can get the whole list even when there are multiple dates in column A:
```

```javascript
let person={
name:"kwame";
age:45
}
```
Object literals were easy to create and less ambiguous to write.
It was all rainbows and chocolate until I wanted the objects I created to share features and to reduce redundancy in the code I wrote. I started writing classes for this and I was happy per say. Some redundancy still remained until I read about the second letter of the SOLID principle, Open-closed principle
## OPEN-CLOSED PRINCIPLE
If you have been writing JavaScript for more than 3 days then you have used this principle before. Shocking right? Well, I guess that's the cool thing about JavaScript. My favorite definition of this principle is by Bertrand Meyer.
"A software artifact should be open for extension but closed for modification."
Let's break down this statement's key words.
1. _software artifact_ may mean a lot of things but in this context take a software artifact as a module or a class.
2. _open for extension_. This generally means that your class or module should allow the ability of a user (by user I mean the programmer using that class or module) to create new features for his program using the functions or methods from classes or modules.
3. _closed for modification_. This the twist of the Bertrand's definition that makes me love it very much. Well, since our classes have multiple features the programmer would love to use, the implementation of these new features should not involve the programmer re-evaluating the parent class and making tweaks to it.
Khalil Stemmler expanded on this by saying
_"Write your code in a way that if you want to add new functionality you don't rewrite the existing code"_
If a user wants to change how a certain method is implemented in the parent class then they should simply override the method.
Overriding simply means re-writing a method from the parent class to the daughter class.
For instance, let me create a class Animal
```javascript
Class Animal{
walk(){
console.log("Hop")
}
eat(){
console.log("Chew very loudly")
}
}
```
our animal has two behaviours. Eating and walking.
My chicken has these two behaviors but how my chicken does these two behaviors is different. Firstly, it doesn't hop and it doesn't chew very loudly.
Well by tweaking my animal class to match these chicken characteristics then all should be fine. But this is not the best approach because what if I want to add another animal let's say a puppy? we cannot have our puppy show the characteristics of a chicken.
Here is where the open-closed principle swoops in as our knight and shining amour to save us from bad code.
The chicken class will simply override the characteristics of our animal. That way the open/closed principle will not be broken.
```javascript
class Chicken extends Animal{
walk(){
console.log("on two legs");
}
eat(){
console.log("crow after eating a seed")
}
sleep(){
console.log("on the roof")
}
}
```
The chicken class was able to add new features without needing to modify the animal class.
## Closing thoughts.
This is part two of a series. I would recommend checking out the previous blog post.
This rule helps you write better modules and classes. A good programmer doesn't follow all the principles of code but knows when to use the right principle and when to not follow another principle. | mtendekuyokwa19 | |

However, while the cloud is convenient, it... | 0 | 2024-06-11T09:47:31 | https://dev.to/nicholajones075/explore-cloud-security-management-everything-you-need-to-know-faj | cloudsecurity, cloudmanagement, itsecurity, cloudstrategy | Cloud software is being used by more and more businesses. However, while the cloud is convenient, it is also very important to have strong cloud security authority. It is essential to comprehend the significance of cloud security, and it is necessary to take appropriate steps to protect your company's data, reputation, and financial performance. We'll talk about the basics of cloud security management, as well as the risks that come with it and the best ways to lower those risks.
## Cloud Security Management
It includes the rules, procedures, and tools that are used to keep cloud-based systems, data, and apps safe from hackers, data breaches, and other cyber risks. It encompasses a wide range of measures, including access controls, data encryption, network security, and continuous monitoring and incident response.
## The Importance of Cloud Security Management
An individual data breach can have terrible effects, such as losing money, being sued, and damaging your company's image in a way that can't be fixed. Effective cloud security management is crucial for the following reasons:
**Data Protection:** Things like client data, financial records, and intellectual property that are private to your business are kept in the cloud. Strong security measures keep this information private, undamaged, and only accessible to people who are allowed to see it.
**Regulatory Compliance:** There are strict rules about data protection and security in many fields. If you don't follow these rules, you could face big fines and other legal problems. Cloud security management helps ensure your organization remains compliant.
**Business Continuity:** A well-designed cloud security strategy includes backup and disaster recovery plans, ensuring minimal downtime and business continuity.
**Cost Savings:** Struggling with the events of a data breach or hacking attempt, which can include big losses, expensive legal fees, and damage to your image, is much more expensive than taking proactive security measures.
## Common Cloud Security Threats
The cloud has many perks but also brings new security risks that companies must deal with. These are some of the most common [cloud security threats](https://www.bacancytechnology.com/blog/cloud-security-threats-and-risks):
### Unauthorized Access
Inadequate access controls or mishandled credentials can lead to unauthorized access to your cloud resources, putting sensitive data at risk.
### Data Breaches
Cybercriminals may attempt to exploit vulnerabilities in your cloud infrastructure or applications to gain unauthorized access to sensitive data.
### Insecure APIs
APIs are the gateways to your cloud services. Poorly designed or insecure APIs can expose your systems to potential attacks.
### Insider Threats
Malicious or negligent insiders, such as disgruntled employees or contractors, can significantly threaten your cloud security.
### Shared Responsibility Model
Protection is shared among the cloud service provider (CSP) and the client in a cloud infrastructure. Failing to understand and fulfill your responsibilities can lead to security gaps. It's important to choose a top provider of [Managed Cloud Services](https://www.bacancytechnology.com/cloud-managed-services) that fully understands this model and its responsibilities.
## Cloud Security Management Best Practices
Here are some best practices to help secure your cloud infrastructure:
### Implement Strong Access Controls
Controlling who can access what is the basis of cloud security. Strong authentication and authorization tools will help you make sure that only authorized people can access your cloud sources.
### Encrypt Data at Rest and in Transit
Implement encryption for data at rest (stored in the cloud) and in transit (data moving between systems) using industry-standard encryption protocols and key management strategies.
### Secure Your APIs
APIs are the backbone of cloud applications, and their security is paramount. Implement secure coding practices, regularly update and patch APIs, and employ API gateway solutions to monitor and control access to your APIs.
### Regularly Update and Patch Systems
To protect against known risks and lower it of cyberattacks, it's important to keep the cloud environment up to date with the most recent security changes and updates.
### Implement Network Security Controls
Secure your cloud environment by implementing network security controls, such as virtual private clouds (VPCs), network segmentation, firewalls, and intrusion detection/prevention systems (IDS/IPS).
### Continuous Monitoring and Incident Response
Continuously monitor your cloud environment for potential security incidents and anomalies. Make an incident action plan that spells out what to do during a security breach, such as how to contain the problem, investigate it, and get it back up and running.
### Compliance and Governance
Make sure that your cloud safety protocols comply with the rules and regulations that apply to your business. Implement a robust governance framework that defines roles, responsibilities, and processes for managing cloud security across your business.
### Conduct Regular Audits and Risk Assessments
Check your cloud security periodically and do risk reviews to find possible weak spots and places to make improvements. This proactive method helps you avoid new threats and ensure your security measures keep working.
## Conclusion
Cloud security management is no longer an option but necessary for businesses of all sizes. By understanding the risks, implementing best practices, and staying vigilant, you can reap the benefits of cloud technologies while safeguarding your company's valuable assets. Putting cloud security first will not only keep your business safe from possible threats but also help you gain trust with your clients, partners, and other important people.

1,884,188 | Crypto News | Future Trends and Developments in Cryptocurrency: Innovation and Integration The landscape of... | 0 | 2024-06-11T09:22:47 | https://dev.to/landercesca24/crypto-news-4he6 | web3, blockchain, cryptocurrency, news | **_Future Trends and Developments in Cryptocurrency: Innovation and Integration_**
The landscape of cryptocurrencies and crypto cards is rapidly evolving, driven by a surge in innovation and technological advancements. This article explores the emerging trends in decentralized finance (DeFi), non-fungible tokens (NFTs). These developments promise to reshape the financial ecosystem, offering broader acceptance and integration with traditional financial services.
**_Emerging Technologies in Cryptocurrency_**
**1. Decentralized Finance (DeFi):**
Decentralized Finance, commonly known as DeFi, is a type of finance built on the blockchain that does not rely on financial instruments provided by financial institutions such as brokerage firms, exchanges, or banks, but instead utilizes smart contracts (e.g., Ether) on the blockchain to carry out financial activities. The DeFi platform allows people to lend or borrow money from others, trade cryptocurrencies, and earn interest in a savings-like account. DeFi continues to disrupt traditional financial systems by providing decentralized alternatives for lending, borrowing, and trading. The key trends shaping DeFi in 2024 include:
**● Real-World Asset Tokenization:** The tokenization of real-world assets (RWAs) such as real estate, art, and commodities is gaining traction. This process involves creating digital tokens representing physical assets, thereby increasing liquidity and accessibility. For instance, projects like MakerDAO are integrating U.S. Treasury bonds into their protocols to offer more stable and reliable yield options (Cointelegraph) (ZenLedger).
**● Yield-Bearing Stablecoins:** The emergence of yield-bearing stablecoins backed by tokenized real-world assets is attracting conservative investors. These stablecoins offer stability while providing returns from underlying assets like Treasury bills, enhancing liquidity and innovation within the DeFi space (Gate.io).
**● Interoperability and Integration:**As DeFi matures, the focus is on integrating with traditional financial systems and enhancing interoperability. Central Bank Digital Currencies (CBDCs) and institutional adoption of DeFi protocols are paving the way for seamless cross-border transactions and new financial products (Innova Solutions).
**Potential Impact on the Market**
The rise of DeFi has democratized access to financial services, particularly benefiting individuals in regions with underdeveloped banking infrastructure. By enabling anyone with an internet connection to participate, DeFi could significantly increase global financial inclusion. Additionally, the transparency and efficiency of DeFi systems could lead to lower costs and more competitive financial products, challenging traditional financial institutions to innovate or risk obsolescence.
**Conclusion**
Emerging technologies like DeFi and NFTs are set to transform markets by democratizing financial services and creating new asset classes. DeFi can democratize financial services, reduce financial costs, and create new market competitiveness. Their emergence represents another innovation based on traditional finance, integrating cutting-edge technologies of today and holding significant historical development value.

_Photo: Craft Conf_
_For more content like this **[subscribe to the ShiftMag newsletter](https://shiftmag.dev/newsletter/)**._
Where there was high demand, high salaries, and ample benefits – now are **layoffs, hiring freezes** , and **promotions so scarce** that they have become exceptions.
Where recently there were opportunities to work with exciting new technology, there are now TypeScript and PHP.
Where there was a team of a backend developer, a frontend developer, an iOS developer, an Android developer, a QA Engineer, and a web developer, there is now a team of two or three full-stack developers.
**Gergely Orosz** , the author of the number one tech newsletter, [The Pragmatic Engineer](https://www.pragmaticengineer.com/), says the **professional lives and career opportunities of software developers** globally have **changed drastically** in the last two years.
Orosz talked about **the drastic change** at [the Craft Conf conference](https://craft-conf.com/2024) in Budapest in his talk titled _What’s Old is New Again._
## Less Rust, more full-stack
The current changes in the labor market and decreasing developer demand remind him of the aftermath of the dotcom crash. What prompted the change now?
How did developers go from being **highly demanded** and almost spoiled by benefits to the point where even they are not sure **if they will be out of work in a few months**?
To the point that not only small startups (or larger ones, but with questionable profitability and sustainability of the business model) but also **_big tech_ companies** with annual profits in the billions of dollars routinely do massive [layoff rounds](https://shiftmag.dev/layoff-resilience-developers-414/)?
The reason lies in **the rise in interest rates** by which the American central bank reacted to the increase in inflation. This, in turn, led to less startup funding, fewer tech IPOs, and massively cut tech budgets at companies of all sizes.
Massive rounds of layoffs and stalled hiring have led to **a surplus of developers in the job market** , which, according to Orosz, has meant that **developers have to adapt to changed circumstances** —not just about what their career prospects are, but also what their day-to-day work looks like:
> _While developers were in high demand, companies were forced to attract them with **shiny and new tech stacks** and opportunities to experiment._
>
> _Now that they don’t have to do that anymore, companies will turn to tried-and-tested tech stacks. Therefore, it will be much **easier to find a job as a TypeScript engineer** than as a Rust engineer._
Orosz also predicts a decrease in specialization as engineering teams get smaller.
_The team that once had frontend and backend developers, iOS and Android developers, DevOps, and QA engineers would probably be reduced to 3 or 4 full-stack engineers, which also makes full-stack engineers more desirable to employers._
## Shift left = more work
Software engineers will also notice an acceleration of the “shift left” trend that has been happening in IT for a couple of years now—developers are now expected to be **involved in testing, QA, and performance evaluation** even before the first line of code is written. Furthermore, developers are increasingly expected to **deploy their code, deal with security, monitoring, and architecture, get involved in project planning…**
They will have to accept that they will receive **fewer raises and promotions** for these new job descriptions. Orosz mentioned Spotify’s recently introduced Mastery program, which encourages employees to **become masters of what they do**. The company sells it as a break from climbing the company ladder. Still, he sees it for what it is—a way to keep engineers satisfied with occasional raises or changes in job status without real promotions.
## Tough times for the engineering managers
He adds that the new professional environment is particularly challenging for engineering managers.
_Fewer employed people means fewer _ **_people needed to lead people_** _. For many engineering managers, the labor market situation is really difficult, and that’s why I advise everyone to accept the fact that _ **_they will have to code actively_** _or be involved operationally in some other way part of the time._
> _Let’s not forget that until recently, engineering managers had spent at least half of their working time recruiting new people. Now that there are no job openings or they are scarce, they must convince employers that they have filled that time with something useful for the company._
_Engineering managers will have to shift to being more technical in their roles._
## AI, the elephant in the room
Last but not least, the job descriptions and opportunities for software engineers are also rapidly changing due to artificial intelligence and **tools that program more and more often and better** _._
Orosz says software engineers are in for a lot of learning:
> _AI will not replace you but will make you more productive. You must constantly learn to be a desirable employee in these new circumstances. **Learn how large language models work** or how to use **developer AI tools** so that they are not your enemies but your allies._

1,884,200 | Persuasive Tech Presentations and Public Speaking Algorithm | Good public speaking is crucial to captivate an audience. I want to help you nurture this skill.... | 0 | 2024-06-11T09:34:08 | https://dev.to/martinbaun/persuasive-tech-presentations-and-public-speaking-algorithm-2ono | beginners, productivity, learning, community | Good public speaking is crucial to captivate an audience. I want to help you nurture this skill.
>*Please use this skill for good and not world domination.*
## What is a technical presentation?
This presentation explains technical stuff, delivering it in simpler terms. It involves reducing the content difficulty while educating or convincing others to adopt whatever is presented.
You take something complex and make it easy for all to grasp. How can you improve public speaking and make a good tech presentation? Let's look at some crucial public speaking tips.
## Content and how do you present it
What you say and how you say it matters. Everything revolves around content. I usually ask myself about the presentation's purpose. I prioritize understanding what's important to the audience and what's in it for them.
>*Are you forming a new opinion? Are you promoting something? Are you looking for funding?*
These objectives should be clear because they form the foundation for everything else. Here are other vital pointers that contribute to the best content for a public speaking project:
- Present one idea at a time.
- Eliminate jargon.
- Have a structure.
- Include stories and personal experiences.
- Offer inspiration, not just information.
- Use visuals.
- Be authentic.
- Have short pauses in between the presentations.
## Catchy and easy-to-understand slides
Slides form a big part of technical presentations. All slides should have an introduction and a conclusion. The intro should convince your viewers that it is worth their time and attention.
The last slide (conclusion) reminds the audience of the presentation's gist. Whatever is on this slide should leave an imprint in their mind that encapsulates your message.
Read: *[12 tips for starting an online business](https://martinbaun.com/blog/posts/12-tips-for-starting-an-online-business/)*
Here are other things to keep in mind:
### Don't begin your presentation with an outline slide (only during each vital section).
Keep slides clutter-free. This means not using a lot of text and other visual material. A great way to implement this rule is to use bullet points frequently, making your content easy to skim.
### Maintain consistent builds or animations.
I use descriptive titles for each slide (and don't use the same one for more than one slide)
I never read texts and other info on slides verbatim. The content is there as a guide. It's best to speak naturally.
>*Keep fonts larger (and make specific information bold). Stick to standard fonts like Sans-Serif, Georgia, Arial, etc.*
Incorporate images and other visual elements like diagrams. These shouldn't be generic but tailor-made for your presentation. The visuals must avoid glitz or fanciness. Keep them simple, but attractive.
## Presentation
This is where your public speaking confidence should shine through. How is this achieved?
I find someone who appears actively engaged and focus on them. This gives me a general vibe of my audience.
>*Instead of fillers, I take a breather or drink some water. This exudes that I'm not afraid of silence.*
I always remain standing during my presentation. This makes me appear more energetic and allows me to make eye contact.
Don't face or stand before the screen. It prevents you from making that connection with the viewers. Always face them. It should be brief if you need a moment to look at your equipment, like a laptop.
>*Avoid filler words such as "um," "uh," "er," and so on. They make you sound hesitant. You can eliminate these when practicing techniques for public speaking.*
## Remember to smile.
If you are passionate about a subject, it will show and be attractive.
Body language is another crucial element. Aside from eye contact and having a smile:
Avoid crossed arms, hands behind your back, or in your pocket.
## Use various hand gestures.
Keep an upright and relaxed posture.
> *Move a little (if the environment allows it) to add variety to your presentation.*
Remember, these are general guidelines. It's a case of different strokes for different folks. You should be able to find what works for you.
## Practice talks
Practice is involved in mastering the art of public speaking. I started my practice talk with a tiny audience (not above ten). An environment with actual people allows you to receive honest feedback that you can implement when it's show time.
Recording the session helps you see how you appear in a public setting. Another tip is to hand out slides in hard copy format (with slide numbers) for your audience to make helpful notes.
This is another type of feedback to help prepare you for the talk. Practice as much as you can by yourself aloud. Use all the available opportunities, from when you're in the shower to looking at the mirror.
## Speak with conviction
Conviction builds confidence in public speaking. Presenters must have the expertise and show they've studied their subjects well to persuade their viewers. The first thing you can do here is to memorize your presentation instead of reading it aloud.
This doesn't seem to leave any room for doubt in your audience and shows your authority on the subject. Here are other ways of adding conviction:
>*Use the active voice instead of the passive voice. It's more powerful to say "leaders must present" than "leaders should do the presentation."*
Have an affirmative tone by taking out negative language or vocabulary with uncertainty. For example, saying, "I think government leaders are not doing enough to address global poverty," doesn't exude confidence. Why? Firstly, "I think" sounds like a guess. The statement needs more urgency. So, "I believe government leaders must address global poverty" makes you sound commanding.
Avoiding ambivalent words like "sort of," "kind of," etc. is another way to have conviction. It also helps to make your point concise and has less filler.
## Offer ideas or alternative solutions.
No matter how persuasive you are, be prepared for objections. It means you should practice doggedness. Have alternative solutions and ideas to address obstacles that your audience might face.

To never be caught off guard, use a simple tip in a tricky situation. Good advice is to say 'Let's take this afterwards.' This could even involve asking for a second shot at a presentation where you can make adjustments. Most people will never actually discuss something later. The point is to pay attention to your viewers and deliver what resonates with them.
## How can you overcome the fear of public speaking?
Fortunately, there are various ways of overcoming the fright.
Be knowledgeable about your topic. When someone knows something well, they can speak about it for hours without hesitation. Knowledge is one of many crucial things. You can reduce the fear by understanding how you will respond to challenging questions.
## Get organized ahead of time.
You plan to fail if you fail to plan. Practice, practice, practice! Practice with a few people you trust to give you feedback or practice alone in front of a mirror. Make a video to see where you could improve.
I like incorporating visualization. Remain in a mind state of optimistic thoughts. I know that positive thinking lessens anxiety, which will help deliver your message in the smoothest way possible.
Read: *[Don't do SOPs, do this instead](https://martinbaun.com/blog/posts/dont-do-sops-do-this-instead/)*
>*Take deep breaths. I do this before the presentation and during my speech. It calms my nerves and helps my audience process the content steadily.*
## How to start a technical presentation?
Include all these elements in your tech presentation:
>*State core concepts of the presentation*
The first 30 seconds should be a brief self-introduction to let the audience know who you are. You'll want to convey your headline message, the big idea for your viewers to absorb instantly.
## Make a captivating statement.
An interesting statement should come as you're stating the core concepts. I make provocative statements to invoke surprise, amusement, or even fear.
Another technique is sharing a personal story or joke related to the topic. The point is to break the ice. You can judge how best to do this depending on your presentation and audience.
Read: *[Resiliency in Job Hunting](https://martinbaun.com/blog/posts/resiliency-in-job-hunting/)*
## Organize information meaningfully
After the introduction and statement, you'll want to guide your viewers on the core topics that will be covered. This is where the organization is necessary. You can divide your talk by the intro, body, and conclusion. I've covered the introduction. Let's cover the body.
There are several ways of delivering this section. I prefer a chronological approach where I recount events from the start of a particular time until now. Another method is where I talk about a problem before offering a solution.
Regardless, your body should have key and structured points you address individually. These should be supported with as much compelling evidence as possible. Briefly summarize the points by relating them to the main topic before moving to the next one. Your audience should be aware of the various transitions.
Finally, your conclusion should have a resonating message that reinforces the initial purpose of your presentation. Have a compelling call to action for your audience to learn more or contact you.
>*Remember that thanking them is necessary.*
## Use a professional layout and design.
We know that a person's attention span is short. A surefire way to captivate people is by getting them to participate in your presentation. I include a lot of interaction with the audience by:
- Asking "raise your hand if..." questions or open-ended questions
- Running a real-time poll that the people can access on their app
- Allowing your audience to access your slides on their phones using an app
- Having your viewers repeat certain information or phases aloud
- Taking questions during the presentation
- Explaining an exercise that the audience can do in a few minutes in pairs
Being a good speaker has several benefits. One of them is likely to know how to keep your developers happy. However, if you are hesitant to speak up, this article can help: [How To Keep Your Developers Team Happy.](https://martinbaun.com/blog/posts/happy-developers-it-is-possible/)

The client of mine is using Seeburger EDI solution. It is deployed on prem and mainly only does various message translations. Effectively, it is a bottleneck as there is no scaling if the load goes above what hardware is capable of handling. Hence, the question I have is this, is it possible to containerise Seeburger solution, make it stateless and deploy on the cloud.
Thanks you in advance.

1,884,194 | Workflow Orchestration on AWS: The Ultimate Guide to AWS Step Functions | Visit my blog Practical Cloud to read more Devops/Cloud topics. In the dynamic world of cloud... | 0 | 2024-06-11T09:27:08 | https://practicalcloud.net/workflow-orchestration-on-aws-the-ultimate-guide-to-aws-step-functions/ | aws, cloud, devops | Visit my blog [Practical Cloud](https://practicalcloud.net) to read more Devops/Cloud topics.
In the dynamic world of cloud computing, orchestrating complex workflows across multiple AWS services is crucial for creating scalable and maintainable applications. AWS Step Functions, a serverless orchestration service, is designed to simplify this task by allowing cloud engineers to coordinate distributed applications and microservices effectively. This ultimate guide to AWS Step Functions will cover everything a cloud engineer needs to know, from basic concepts to advanced features, ensuring you're equipped to leverage this powerful service in your cloud infrastructure.
## What Are AWS Step Functions?
AWS Step Functions is a fully managed service that enables the coordination of various AWS services into serverless workflows. These workflows are composed of a series of steps, with each step representing a state that can perform tasks, make decisions, and handle errors. The primary advantage of using Step Functions is the ability to design and execute workflows in a visual manner, improving both development speed and application reliability. AWS Step Functions is a powerful orchestration service that simplifies the coordination of complex workflows across various AWS services. Its visual workflow design, built-in error handling, seamless integration capabilities, and support for different state machine types make it an invaluable tool for cloud engineers.
AWS Step Functions facilitate the orchestration of microservices, making it easier to manage complex distributed systems by abstracting the underlying interactions between different services. This results in a more organized, maintainable, and scalable architecture.
Key Concepts of AWS Step functions
Tasks
The fundamental building blocks of a Step Functions workflow. They represent individual units of work that your application needs to perform.
Types:
AWS Service Tasks: Invoke other AWS services like Lambda functions, S3 operations, DynamoDB interactions, etc. Step Functions handles the communication and execution of these tasks.
Wait Tasks: Introduce pauses or delays in the workflow execution for a specified duration.
Pass Tasks: Used for data manipulation within the workflow. They don't call external services but allow you to modify or pass data between steps.
Events
Definition: Signals that trigger transitions between states in a Step Functions workflow. They represent significant occurrences during execution.
Types:
Execution Started: Emitted when a workflow execution is initiated.
Task Started: Sent when a task begins execution.
Task Succeeded: Emitted after a task finishes successfully.
Task Failed: Sent when a task encounters an error.
Task Timed Out: Emitted if a task exceeds its designated timeout period.
Execution Failed: Sent when the entire workflow execution fails.
Execution Succeeded: Emitted when the workflow execution completes all steps successfully.
States
Definition: Represent the different stages or conditions within a Step Functions workflow. They dictate how the workflow progresses based on events and conditions.
Types:
Task State: The most common type, representing a step where a task is executed.
Pass State: Used to manipulate data within the workflow without calling external services.
Wait State: Introduces a pause or delay in the workflow execution.
Choice State: Enables conditional branching in the workflow based on expressions or rules that evaluate input data or state of the execution. Next steps are chosen based on the outcome.
Parallel State: Executes multiple tasks concurrently, useful for speeding up workflows with independent steps.
State Machine
Definition: The central construct in Step Functions. It defines the overall workflow logic by describing the sequence of states, tasks, events, and transitions that make up the application's execution process.
Components: A state machine is built from states connected by transitions. Transitions are triggered by events and may include conditions that must be met for the transition to occur.
## Additional Key Concepts
Execution: An instance of a state machine running. It represents a single execution of the workflow with its current state, input data, and history of events.
Execution History: A record of all events that occurred during an execution, providing an audit trail for debugging and monitoring.
Retries: Configure Step Functions to automatically retry failed tasks a specified number of times before considering the execution failed.
Timeouts: Define timeouts for individual tasks to prevent workflows from getting stuck waiting for unresponsive services or long-running operations.
Amazon States Language (ASL): A JSON-based syntax used to define state machines in Step Functions. It specifies the states, transitions, tasks, events, and other workflow logic.
Key Features of AWS Step Functions
1. Visual Workflow Design
One of the standout features of AWS Step Functions is its graphical interface, which allows users to design and visualize the execution flow of their applications. This visual representation is crucial for understanding how different components interact within a workflow. The drag-and-drop interface not only simplifies the design process but also aids in debugging and monitoring, enabling developers to quickly identify and resolve issues.
2. Built-in Error Handling
Robust error handling is a critical aspect of any workflow, and AWS Step Functions excel in this area. The service includes built-in mechanisms for error handling, retries, and catch blocks. These features ensure that workflows can gracefully handle failures and exceptions, enhancing the reliability and resilience of your applications. By configuring retry policies and catch conditions, developers can define precise error recovery strategies tailored to their specific use cases.
3. Seamless Integration with AWS Services
AWS Step Functions seamlessly integrate with a wide array of AWS services, providing a cohesive environment for building complex workflows. Whether you need to invoke AWS Lambda functions, manage containers with Amazon ECS, send notifications via Amazon SNS, or handle message queues with Amazon SQS, Step Functions can coordinate these services effortlessly. This tight integration ensures that workflows can span across multiple AWS services, enabling sophisticated and scalable cloud solutions.
4. State Machine Types
AWS Step Functions offer two distinct types of state machines to cater to different use cases:
**Standard Workflows:** These are designed for long-running workflows that require high durability and at-least-once execution guarantees. Standard Workflows are ideal for scenarios where data consistency and reliability are paramount, such as financial transactions, order processing, and data analysis pipelines.
**Express Workflows:** Express Workflows are optimized for high-volume, short-duration event processing. They provide a cost-effective pricing model and at-most-once execution guarantees, making them suitable for real-time data processing, event-driven applications, and other high-throughput tasks. Express Workflows are designed to handle large bursts of activity with low latency.
Here's a side-by-side comparison of the two:
## Getting Started with AWS Step functions
## Step 1: Define Your Workflow
Begin by defining your workflow using Amazon States Language (ASL), a JSON-based, structured language. Each state in the workflow can perform various tasks, such as invoking a Lambda function, making decisions based on conditions, or waiting for a specified time.
```
{
"Comment": "A simple AWS Step Functions example",
"StartAt": "HelloWorld",
"States": {
"HelloWorld": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:HelloWorld",
"End": true
}
}
}
```
Step 2: Create a State Machine
Using the AWS Management Console, CLI, or SDK, create a state machine by providing the workflow definition and specifying the state machine type (Standard or Express).
```
aws stepfunctions create-state-machine --name HelloWorldStateMachine --definition file://state-machine-definition.json --role-arn arn:aws:iam::123456789012:role/service-role/MyRole
```
**Step 3: Start Execution
**Start an execution of your state machine using the AWS Management Console, CLI, or SDK, and pass any required input.
```
aws stepfunctions start-execution --state-machine-arn arn:aws:states:us-east-1:123456789012:stateMachine:HelloWorldStateMachine --input '{"key": "value"}'
```
**Step 4: Monitor Execution**
Monitor the execution of your state machine using the AWS Management Console, where you can see the step-by-step progress, inspect input and output of each state, and diagnose any errors.
## Best Practices for Working with Step Functions
**1. Step Functions with AWS Lambda**
Leveraging AWS Lambda within Step Functions allows for a serverless, event-driven approach to workflow orchestration. By combining the flexibility of Lambda functions with the coordination capabilities of Step Functions, developers can build scalable, decoupled systems that respond dynamically to events.
To learn more about AWS Lambda, [read this post](https://practicalcloud.net/master-aws-lambda-triggers-destinations-mappings-invocations-explained/).
**2. Service Integrations and API Gateway**
Step Functions can integrate with external APIs via Amazon API Gateway, enabling workflows to interact with third-party services or expose workflows as APIs. This integration extends the capabilities of Step Functions beyond the AWS ecosystem, facilitating a more versatile and interconnected architecture.
**3. Monitoring and Logging**
AWS Step Functions provide extensive monitoring and logging features through Amazon CloudWatch. Developers can track the performance of workflows, set up alarms for specific events, and analyze logs to gain insights into workflow execution. These tools are essential for maintaining the health and performance of your applications.
**4. Security and Access Control
**Ensuring security and proper access control is vital when managing workflows that interact with multiple services. AWS Step Functions support AWS Identity and Access Management (IAM) policies, allowing you to define precise permissions for each state within a workflow. This fine-grained access control helps secure sensitive operations and data.
## Advanced Features of AWS Step Functions
**1. Parallel State**
The Parallel state allows the execution of multiple branches of a workflow simultaneously.
Example:
A workflow to process customer orders can use a Parallel state to handle inventory checks, payment processing, and notification sending at the same time.
```
{
"Comment": "Parallel state example for processing customer orders",
"StartAt": "ProcessOrder",
"States": {
"ProcessOrder": {
"Type": "Parallel",
"Branches": [
{
"StartAt": "CheckInventory",
"States": {
"CheckInventory": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:CheckInventory",
"End": true
}
}
},
{
"StartAt": "ProcessPayment",
"States": {
"ProcessPayment": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:ProcessPayment",
"End": true
}
}
},
{
"StartAt": "SendNotification",
"States": {
"SendNotification": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:SendNotification",
"End": true
}
}
}
],
"End": true
}
}
}
```
**2. Map State**
The Map state iterates over a collection of items and performs a set of actions for each item.
Example:
A workflow to process a batch of uploaded images can use a Map state to apply transformations to each image in parallel.
```
{
"Comment": "Map state example for processing uploaded images",
"StartAt": "ProcessImages",
"States": {
"ProcessImages": {
"Type": "Map",
"ItemsPath": "$.images",
"Iterator": {
"StartAt": "TransformImage",
"States": {
"TransformImage": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:TransformImage",
"End": true
}
}
},
"End": true
}
}
}
```
**3. Choice State**
The Choice state allows for conditional branching in workflows based on input data.
Example:
A workflow for user registration can use a Choice state to branch based on user type (e.g., "Admin" or "User").
```
{
"Comment": "Choice state example for user registration",
"StartAt": "CheckUserType",
"States": {
"CheckUserType": {
"Type": "Choice",
"Choices": [
{
"Variable": "$.userType",
"StringEquals": "Admin",
"Next": "RegisterAdmin"
},
{
"Variable": "$.userType",
"StringEquals": "User",
"Next": "RegisterUser"
}
],
"Default": "UnknownUserType"
},
"RegisterAdmin": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:RegisterAdmin",
"End": true
},
"RegisterUser": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:RegisterUser",
"End": true
},
"UnknownUserType": {
"Type": "Fail",
"Error": "UnknownUserTypeError",
"Cause": "The user type is not recognized"
}
}
}
```
**4. Wait State**
The Wait state introduces a delay before transitioning to the next state.
Example:
A workflow for retrying a task after a specific time interval can use a Wait state.
```
{
"Comment": "Wait state example for retrying a task",
"StartAt": "InitialTask",
"States": {
"InitialTask": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:InitialTask",
"Next": "WaitBeforeRetry"
},
"WaitBeforeRetry": {
"Type": "Wait",
"Seconds": 60,
"Next": "RetryTask"
},
"RetryTask": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:RetryTask",
"End": true
}
}
}
```
**5. Error Handling with Catch and Retry**
Step Functions can handle errors and retries using Catch and Retry mechanisms.
Example:
A workflow for processing orders can use Catch and Retry to handle transient errors.
```
{
"Comment": "Error handling example with Catch and Retry",
"StartAt": "ProcessOrder",
"States": {
"ProcessOrder": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:ProcessOrder",
"Retry": [
{
"ErrorEquals": ["TransientError"],
"IntervalSeconds": 5,
"MaxAttempts": 3,
"BackoffRate": 2
}
],
"Catch": [
{
"ErrorEquals": ["States.ALL"],
"Next": "HandleError"
}
],
"End": true
},
"HandleError": {
"Type": "Task",
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:HandleError",
"End": true
}
}
}
```
## Use Case Scenarios for AWS Step Functions
**1. ETL Pipelines**
AWS Step Functions can orchestrate Extract, Transform, Load (ETL) workflows by coordinating tasks such as data extraction, transformation, and loading in a streamlined manner. For instance, data can be extracted from Amazon S3, transformed using AWS Glue, and loaded into a Redshift cluster. By visualizing the ETL process, Step Functions enhance monitoring and debugging, ensuring data integrity and efficient pipeline management. Additionally, built-in error handling and retry mechanisms ensure robustness, minimizing downtime and operational issues.
**2. Microservices Orchestration**
In a microservices architecture, AWS Step Functions can manage the interaction between various services, ensuring tasks are executed in the correct order and handling retries and failures gracefully. For example, in an e-commerce application, Step Functions can orchestrate microservices for user authentication, order management, payment processing, and notification services. By defining workflows visually, developers can maintain clear, organized, and easily adjustable processes, leading to higher reliability and easier troubleshooting.
**3. Machine Learning Model Training**
Automating the process of training machine learning models can be efficiently achieved with AWS Step Functions. Create a workflow that includes data preprocessing, model training, hyperparameter tuning, and deployment using AWS services like SageMaker. Each step in the training pipeline can be independently managed and monitored, ensuring that data transformations are correctly applied, models are trained with optimal parameters, and deployments are automated for real-time inference. This automation not only speeds up the development cycle but also enhances the reproducibility and reliability of machine learning projects.
**4. Order Processing System**
Orchestrate an e-commerce order processing system with AWS Step Functions to handle tasks such as inventory checks, payment processing, order confirmation, and shipping notifications. By coordinating these tasks in a sequential and reliable manner, Step Functions ensure that each step in the order process is completed before moving to the next. Built-in error handling ensures that failures in any part of the process can be retried or managed gracefully, reducing the risk of incomplete orders and improving customer satisfaction. Read this practical project on [implementing a payment processing workflow on AWS](https://practicalcloud.net/building-a-payment-processing-workflow-for-a-fintech-app-using-aws-step-functions-and-aws-sam/).
**5. Batch Processing**
AWS Step Functions can coordinate batch processing jobs involving large datasets, such as image processing, data conversion, and report generation. For example, a workflow can be created to process images uploaded to an S3 bucket, convert them to a different format using Lambda functions, and store the processed images back in S3 or another storage service. This orchestration allows for scalable and efficient handling of high-volume data processing tasks, ensuring each job is completed successfully with appropriate logging and error handling.

**6. IoT Data Processing**
Manage IoT workflows that collect data from devices, process the data in real-time, and store the results in a database using AWS Step Functions. For instance, data from IoT devices can be ingested using AWS IoT Core, processed in real-time using Lambda functions, and stored in Amazon DynamoDB or RDS for further analysis. Step Functions ensure that data processing workflows are executed reliably and efficiently, with built-in error handling to manage device connectivity issues or data inconsistencies.
**7. User Onboarding**
Automate the user onboarding process by integrating multiple services to handle tasks such as account creation, sending welcome emails, and setting up user preferences. AWS Step Functions can coordinate these tasks, starting with user data validation, followed by account creation in Amazon Cognito, sending personalized welcome emails via Amazon SES, and setting up initial user preferences in a database. This automation ensures a smooth and consistent onboarding experience for new users, enhancing user satisfaction and engagement.

Today I’d like to start my series of articles on using the LangChain open source tool-set.
[LangChain](https://github.com/langchain-ai/langchain) is one of the most used frameworks to create AI agents with, if not THE most used. With nearly 90.000 stars and almost 14000 forks on GitHub at the time of this article, we can safely say it is popular.
Reason enough for me to start covering it. To kick things off with, let’s answer a few essential questions.

## Introduction
### What is a RAG AI Agent?
Retrieval Augmented Generation (RAG) is a technique to enhance the accuracy and reliability of AI with facts retrieved from other sources.
Originally the RAG name was coined in [this](https://arxiv.org/pdf/2005.11401) paper, the authors stated:
> RAG could be employed in a wide variety of scenarios with direct benefit to society, for example by endowing it with a medical index and asking it open-domain questions on that topic, or by helping people be more effective at their jobs
Essentially you can create your own set of sources that you have vetted for accuracy and fit for purpose. Creating applications with your specific needs in mind, and without potential bias or opinion from the original AI.
RAG’s are a great way to provide business solutions that can run locally with open source AI models such as [Llama](https://llama.meta.com/), or large cloud scale AI’s such as [OpenAI](https://openai.com/).
### What is LangChain and LangFlow?
[LangChain](https://www.langchain.com/) is an open source Python library that can integrate with AI models using API’s and functions. With LangChain you can create natural language interactions with an AI using concepts such as Chains, and Prompts to weave together a custom RAG AI.
[LangFlow](https://www.langflow.org/) is a GUI that can diagram a LangChain flow to experiment and prototype an AI solution with quickly. It offers drag and drop components and a chat box to immediately start interacting. This simplifies the initial development process of iteration and experimentation.
---
## How do I get started?
To get started with LangFlow creating your AI agent there are 3 options you can choose from:
1. **SAAS Installation using Huggingface spaces:**
- **Private:** [Huggingface account](https://huggingface.co/), then duplicate [LangFlow Spaces](https://huggingface.co/spaces/Langflow/Langflow?duplicate=true) , leave everything on default, click `duplicate space`.
- This will take a bit of time (30+ minutes, not included in the 5 minutes 😜)
- In the mean time head over to the Spaces settings > `Variables and secrets` > `New secret`
- Name: `OPENAI_API_KEY`, Value: your OpenAI key we just copied.
- Go drink a coffee, walk outside, do other things while the Huggingface space is created.
- Then, you can skip to [this](#how-to-create-our-first-rag-ai-with-langflow) chapter.
- **Public:** access the [Public LangFlow](https://huggingface.co/spaces/Langflow/Langflow) service, ready to go but everyone can read it!
- **Do not use your OpenAI API keys here!**
- Then, you can skip to [this](#how-to-create-our-first-rag-ai-with-langflow) chapter.
2. **A Google Cloud installation**. If preferred, go [here](https://docs.langflow.org/deployment/gcp-deployment).
- Then you can skip to [this](#how-to-create-our-first-rag-ai-with-langflow) chapter.
3. **Or, run it on your own machine using VirtualBox**.
- This is my preferred method of choice, it’s low cost and you have full control. Follow along in the next chapter to find out how to quickly set this up.
### How to install LangFlow on your own machine
1. Install Vagrant and VirtualBox:
- Download and install [Vagrant](https://www.vagrantup.com/downloads.html).
- Download and install [VirtualBox](https://www.virtualbox.org/wiki/Downloads).
2) Install via my LangFlow repo:
- `git clone https://github.com/rpstreef/langflow-setup`
- Within the cloned repo; execute; `vagrant up` to install the LangFlow VM with docker and docker-compose.
- Type `make` for all the commands available.
- _Optionally:_
- Run: `make vm` to get access to the Virtual Machine.
- Note if you do not have VBoxManage on your command-line, this will not work.
- Sometimes you could get a message like this; `ssh: connect to host 192.168.1.39 port 22: No route to host`.
- Retry the connection in that case.
- Run: `dry` to see all the containers running
- open your browser and navigate to; `http://localhost:7860/flows`
Now we can start creating a chat bot
> To use the store, you need to register and get an API key [here](https://www.langflow.store/profile/api-key)
## How to create our first RAG AI with LangFlow
This is what we’re going to build today.
To start with, what is the aim of this particular RAG? What do we want it to do?
> A chat bot that can answer detailed questions about any web-page we choose.
A perfect use case for this is article analysis via questions and answers. You can formulate the questions such that the bot can provide additional explanation on harder to understand concepts.
I’m sure there are other uses cases like this, let me know on [Twitter](https://twitter.com/rolfstreefkerk) what you would use it for.
Basically there are two parts to building this RAG chat-bot:
1. We need to retrieve the information we want to ask questions about,
2. then make that information available to the OpenAI chat bot.
---
### Part 1: Processing the web-page data
To start of with, we need to store website text, as a vector, in a database such that we can use it later to ask questions about.
> I’ve added links to the official LangChain documentation for each of the concepts / parts discussed.
1. **[WebBaseLoader](https://python.langchain.com/v0.2/docs/concepts/#document-loaders)**: Enter the Web Page we want to analyze.
2. **[OpenAIEmbeddings](https://python.langchain.com/v0.2/docs/concepts/#embedding-models)**: This will “embed” the information read from the website. We use OpenAI’s `text-embedding-3-small` Model to do this. Which should be ample for most use-cases. This creates a vector representation of the `documents` we’re about to create. The [TikToken](https://python.langchain.com/v0.2/docs/how_to/split_by_token/#tiktoken) tokenizer to make it more accurate for OpenAI to split the text.
3. **[CharacterTextSplitter](https://python.langchain.com/v0.2/docs/concepts/#text-splitters):** This part will cut up the text into `chunks` with a bit of overlap, and outputs these parts as `documents` to `FAISS` the vector database we’re using in this scenario.
4. **[FAISS](https://python.langchain.com/v0.2/docs/integrations/vectorstores/faiss)**: Is the Facebook AI Similarity Search (FAISS) vector database that can store and search vectorized `documents` in memory.
{% embed https://youtu.be/akulwhLfk0Q %}
---
### Part 2: Let’s chat with your RAG
Now that we have the basic information retrieval and vector storage created. We can start adding a Chat AI and chaining the `documents` we’ve created with a [Retriever](https://python.langchain.com/v0.2/docs/concepts/#retrievers) (Search via a question and retrieve `documents` using a prompt via the chat box.
1. **[ChatOpenAI](https://python.langchain.com/v0.2/docs/integrations/chat/openai):** We use the Chat feature offered by OpenAI and set the model to `gpt-3.5-turbo-0125` to save on cost. Additionally the [temperature](https://gptforwork.com/guides/openai-gpt3-temperature) is set to 0.2 to inform the AI we need answers with high probability and not too much creativity (> 0.5 - 1.0)
2. **CombineDocsChain:** We use chain type `stuff`, which basically means the context is the document. For efficiency you could change this to `map_reduce`, but it would mean we need to complicate the Prompt parts to combine the documents with.
3. **RetrievalQAWithSourcesChain:** Chains together and creates the Context from the user question, and the documents retrieved from the Vector database.
4. **Let’s chat:** Now we can ask what our [webpage](https://rolfstreefkerk.com/posts/a-holistic-approach-to-health-and-weight-tracking) is about:
{% embed https://youtu.be/rmjhRU9tPcI %}
---
## Experiment and Test
This is just a starting point, and a working example of how quickly a RAG can be created for a specific purpose. A few things to consider that can optimize the solution;
- Experiment with the token sizes of the _OpenAIEmbedding_ and _ChatOpenAI_.
- Changing the chain type of the _CombineDocsChain_, to `map_reduce`.
- Improving the website text data quality by reducing the token size of the source text ([lemmatization and stemming](https://www.datacamp.com/tutorial/stemming-lemmatization-python)).
> Data input quality has a big impact on RAG output quality.
## Conclusion
In conclusion, let’s summarize what’s been covered and learned:
- Use LangFlow to quickly create a chat-bot that can answer questions on the content of your choice.
- LangFlow consists of many components of the LangChain framework. Understanding these components, can open up new possibilities to automate with LangFlow.
- LangFlow is a playground to experiment with AI. To prototype an idea quickly, then build it with LangChain.
- (*bonus*) Huggingface spaces host a variety of AI generative applications such as image generation with [Stable diffusion](https://huggingface.co/spaces/stabilityai/stable-diffusion-3-medium) or [Midjourney](https://huggingface.co/spaces/prithivMLmods/Midjourney), and [GPT4o chat](https://huggingface.co/spaces/KingNish/OpenGPT-4o). Check it out!
For the next article I’d like to dive deeper into creating a RAG agent using LangGraph, and deploy that to a Docker container. Stay tuned if you’re interested.
For now, lets discuss in the comments below:
- What have you build?
- What can be improved in this example and why?
> Let's continue the discussion on [Twitter](https://twitter.com/rolfstreefkerk)
Appreciate your time and till the next one!

1,884,182 | ALB vs NLB | AWS offers multiple load-balancing solutions tailored to different use cases within the Elastic Load... | 0 | 2024-06-11T09:19:22 | https://dev.to/saumya27/alb-vs-nlb-22hc | aws, alb, nlb | AWS offers multiple load-balancing solutions tailored to different use cases within the Elastic Load Balancing (ELB) service. The two primary types are the Application Load Balancer (ALB) and the Network Load Balancer (NLB). Below is a detailed comparison of ALB and NLB, highlighting their features, use cases, and differences.
**Application Load Balancer (ALB)**
**Key Features:**
**1. Layer 7 Load Balancing:**
- Operates at the application layer (OSI layer 7), making it capable of routing HTTP/HTTPS traffic.
- Supports advanced routing features such as host-based, path-based, and query string-based routing.
**2. Content-Based Routing:**
- Can route requests to different target groups based on the content of the request, allowing for more granular control over traffic distribution.
**3. SSL Termination:**
- Supports SSL/TLS termination, offloading the decryption/encryption work from your backend instances.
**4. WebSockets and HTTP/2:**
- Supports WebSocket and HTTP/2, making it suitable for modern web applications requiring persistent connections and better performance.
**5. WAF Integration:**
- Can integrate with AWS Web Application Firewall (WAF) to protect your web applications from common web exploits.
**.6 Sticky Sessions:**
- Supports session stickiness (also known as session affinity) based on cookies, allowing a client to be bound to a specific target.
**Use Cases:**
- Ideal for web applications needing advanced routing capabilities and content-based routing.
- Suitable for microservices architectures, where different services might require different routing rules.
- WebSocket applications and applications requiring HTTP/2 support.
- Applications needing SSL termination and integration with WAF for enhanced security.
**Network Load Balancer (NLB)**
**Key Features:**
**1. Layer 4 Load Balancing:**
- Operates at the transport layer (OSI layer 4), handling TCP, UDP, and TLS traffic.
- Designed for extreme performance, capable of handling millions of requests per second with ultra-low latency.
**2. Static IP Addresses:**
- Provides a static IP address for the load balancer, which can be useful for whitelisting and consistent endpoint references.
**3. Preserve Source IP:**
- Preserves the client source IP address, which is essential for applications needing to know the original IP address of the client.
**4. TLS Termination:**
- Can offload the TLS termination process from your backend instances, similar to ALB but at the transport layer.
**5. Zonal Isolation:**
- Provides high availability across multiple Availability Zones and can route traffic to healthy targets within a specific zone, ensuring robustness.
**Use Cases:**
- Best suited for high-performance, latency-sensitive applications requiring extreme scalability.
- Applications needing to handle non-HTTP/S traffic, such as TCP and UDP.
- Use cases where preserving the source IP address is critical for the application logic.
- Ideal for microservices requiring simple, fast, and reliable load balancing at the network layer.
**Conclusion**
Choosing between ALB and NLB depends on your specific application requirements:
- Use ALB if you need advanced routing capabilities, support for modern web protocols (HTTP/2, WebSockets), SSL termination, and integration with WAF for web applications.
- Use NLB if you need high performance, low latency, support for TCP/UDP traffic, static IP addresses, and the ability to preserve the client source IP address.
By understanding the strengths and use cases of each load balancer, you can make an informed decision that best suits your application's architecture and performance requirements. | saumya27 |

While reading a bunch of javascript weekly articles online I’ve found an extensive list of open-source packages one-by-one.
We often need or rely on such packages but never discuss them as a tech stack or project.
These small cool packages are a good learning source as well as provide an experience to understand how open-source works in the real world.
Let’s not waste time and start !!
[**Fontsource**](https://fontsource.org/)1700+ open source fonts packaged as npm packages.
[**Prisma**](https://www.npmjs.com/package/prisma) Popular ORM for Node.js and TypeScript

This article explores strategies for reconnecting to RabbitMQ, ensuring that your applications can recover from network disruptions or broker restarts without losing valuable data.
# Setting Up
## Importing Dependencies
```go
import (
"fmt"
amqp "github.com/rabbitmq/amqp091-go"
"log"
"os"
"os/signal"
"syscall"
"time"
)
```
We use `amqp091-go` as a connection for RabbitMQ
## Preparing option
```go
type Config struct {
username string
password string
host string
port int
}
type Container struct {
connection *amqp.Connection
}
type Channel struct {
name string
kind string
durable bool
autoDelete bool
internal bool
noWait bool
args amqp.Table
}
```
- `Config` holds connection configuration.
- `Container` holds the connection to RabbitMQ. In each application, they should have a wrapper for holding the connection.
- `Channel` holds channel configuration.
## Connection Creation
```go
// dial
// create connection and register channel
func dial(config Config, channels []Channel) (conn *amqp.Connection, err error) {
// create connection
conn, err = amqp.Dial(fmt.Sprintf("amqp://%s:%s@%s:%d", config.username, config.password, config.host, config.port))
if err != nil {
return
}
log.Print("rabbitmq connect success")
// register channel
channel, err := conn.Channel()
for _, c := range channels {
err = channel.ExchangeDeclare(c.name, c.kind, c.durable, c.autoDelete, c.internal, c.noWait, c.args)
if err != nil {
return
}
}
log.Print("rabbitmq channels register success")
return
}
```
We create a Go function `dial` to assist in establishing a connection to RabbitMQ. It takes in a `Config` struct containing connection details like username, password, host, and port, and a slice of `Channel` structs representing different channels to be registered with the server.
## Connection Status
```go
func check(container *Container) {
for {
time.Sleep(time.Duration(1) * time.Second)
log.Printf("rabbitmq connected: %v", !container.connection.IsClosed())
}
}
```
We create a Go function `check` to check and print connection status periodically, to have visibility of the connection status.
# Reconnection Code
Below is the full code containing reconnection code. We will walk through step by step to understand how reconnection works in Go with RabbitMQ.
```go
func reconnect(container *Container, config Config, channels []Channel) {
go func() {
for {
reason, ok := <-container.connection.NotifyClose(make(chan *amqp.Error))
if !ok {
log.Print("rabbitmq connection closed")
break
}
log.Printf("rabbitmq connection closed unexpectedly, reason: %v", reason)
for {
time.Sleep(time.Duration(1) * time.Second)
connection, err := dial(config, channels)
if err == nil {
container.connection = connection
log.Print("rabbitmq reconnect success")
break
}
log.Printf("rabbitmq reconnect failed, err: %v", err)
}
}
}()
}
```
This function is a reconnect loop for a RabbitMQ client, and since reconnection creates a brand-new connection, the `reconnect` function is required to have all the values like the initial connection.
1. It starts a goroutine to prevent blocking that listens for the closure of the connection.
2. When the connection is closed, it enters a loop to attempt reconnection.
3. It uses a delay of 1 second (`time.Sleep(time.Duration(1) * time.Second)`) between reconnection attempts.
4. It attempts to reconnect by calling the `dial` function with the provided configuration and channels.
5. If the reconnection is successful, it updates the `container.connection` with the new connection.
6. If the reconnection fails, it logs the error and continues the loop.
## Stitching Together
```go
func main() {
config := Config{
username: "guest",
password: "guest",
host: "localhost",
port: 5672,
}
channels := []Channel{
{
name: "reconnection-exchange",
kind: "direct",
durable: true,
autoDelete: false,
internal: false,
noWait: false,
args: nil,
},
}
container := &Container{}
connection, err := dial(config, channels)
if err != nil {
log.Fatal(err)
return
}
container.connection = connection
go check(container)
defer func() {
if err := container.connection.Close(); err != nil {
log.Print(err)
}
log.Print("rabbitmq connection closed")
}()
reconnect(container, config, channels)
{
quit := make(chan os.Signal, 1)
signal.Notify(quit, os.Interrupt, syscall.SIGINT, syscall.SIGTERM)
<-quit
}
}
```
Now we combine all code together in `main` function.
# Testing
## Running
Before running the code, make sure RabbitMQ is running and accessible. Upon running the code, you should see a message like the one below.
```
rabbitmq connect success
rabbitmq channels register success
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
...
```
This message indicates that the RabbitMQ connection is connected normally.
## Disconnection & Down
After running and connected normally, you can emulate disconnection & server down by manually shutting down the RabbitMQ server. After the server stops, you should see a message like the one below.
```
rabbitmq connection closed unexpectedly, reason: Exception (320) Reason: "CONNECTION_FORCED - broker forced connection closure with reason 'shutdown'"
rabbitmq connected: false
rabbitmq connected: false
rabbitmq connected: false
rabbitmq connected: false
rabbitmq reconnect failed, err: dial tcp [::1]:5672: connectex: No connection could be made because the target machine actively refused it.
rabbitmq connected: false
rabbitmq connected: false
rabbitmq connected: false
rabbitmq reconnect failed, err: dial tcp [::1]:5672: connectex: No connection could be made because the target machine actively refused it.
rabbitmq connected: false
...
```
This message indicates disconnection from the RabbitMQ connection, and you should set up an alert for this event.
## Reconnection
After disconnection, you can emulate reconnection by running the RabbitMQ server again. After the server is up and ready, and the reconnection mechanism is successful, you should see a message like the one below.
```
rabbitmq connect success
rabbitmq channels register success
rabbitmq reconnect success
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
rabbitmq connected: true
```
# Conclusion
In conclusion, the article demonstrates a robust strategy for handling RabbitMQ reconnections in Go, ensuring reliable communication in distributed systems. By implementing a reconnection loop and monitoring the connection status, the application can gracefully recover from network disruptions or broker restarts. This approach enhances the resilience of the system, ensuring that important data is not lost due to temporary connection issues. Using the amqp091-go library, developers can easily implement these reconnection mechanisms, improving the overall reliability of their RabbitMQ-based applications.

If the cash is not pouring into your business, there are high chances the cycle could be disrupted and the overall pipeline would be broken or distressed. A [Medical Billing Company in New Jersey](https://www.aksharmedi.com/medical-billing-services/) can fix this pipeline and ensure a proper flow of better cash and streamlined operations.
To let your revenue cycle stream in a unified direction and your business uptake momentum, you need to balance out a lot of intricacies in your healthcare. One of the prominent players is “Medical Coding”, which can downturn your profits and ROI.
The healthcare services are a two-way road – translation of healthcare services into billable codes and preparation and submission of claims to insurance companies for reimbursement.
Any bumps on these roads or any wrong medical code could hamper the overall process and impact the revenue cycle.
Let’s decode each detail and dive into understanding the entire process.
## What is Revenue Cycle Management in Healthcare?
[Revenue cycle management](https://www.aksharmedi.com/revenue-cycle-management/) refers to systematics, structure and coordinated processes managing the financial aspects of patient care in healthcare organisations. It includes every component, from patient interaction with the healthcare system scheduling to the final payment and reimbursement.
Revenue cycle management includes multiple processes and coding and claim submission is a crucial aspect that can make feast or famine. Either turn profits or redirect to denial, if not adhered to as per laws. A Medical Billing Solution can undertake the entire process, take care of intricacies and ensure that reimbursement is easy without any hindrances.
## Role of Medical Billing Solution
Medical coding is converting healthcare diagnoses, procedures and other services into universal medical alphanumeric codes. There is each code for a patient’s diagnosis procedures performed to treat diagnoses. Whether it’s Regence or Premera, commercial insurance companies, or regulatory payers like Medicare and Medicaid, insurance companies adhere to these standard codes to settle claims and follow up.
Medical Billing services in New Jersey is skilled and knowledgeable with all these processes of patient billing practices, compliance with regulations, claim denials and much more. As a healthcare service provider, you don’t need to memorise codes, comply with guidelines or even evolve with a dynamic environment, all you need is the approach of professionals.
Equifax found in an audit that hospital bills above $10,000 have a tentative error amount of $1300. This causes doctors to lose around $125 billion each year, all due to poor billing practices.
Being a practitioner, you can’t afford to lose hard-earned cash in vain. Streamlined medical billing is not just a win for doctors but also for patients. Try outsourcing with Medical Billing Services New Jersey.
## As per Becker's Hospital Review, 80% of US medical billing contains errors.
Don’t let errors in medical billing and coding termite your profits; choose a Medical Billing Solution for streamlined and better operations.
What are the top challenges in Medical Coding, and How to optimise it?
Responding to evolving and dynamic medical coding challenges is common. Hospitals and healthcare staff do not comply with efficient processes and the latest codings, which subsequently costs their organisation. Administrative waste is a major contributor to rising costs and impacts 30 percent of healthcare spending. Beyond the rising rates of healthcare, wasted time in the workforce can deteriorate cash flow longer than necessary.
Healthcare organisations must emphasise this factor and outsource this functioning to skilled and knowledgeable Medical Billing services in New Jersey to improve their bottom line.
## Improper Coding
Often in a hurry to accomplish the task, medical coders either neglect some codes or add too much information. Fitting the code in the right puzzle is crucial for the reimbursement process. The Centers for Medicare and Medicaid Services predefine hierarchical coding categories. The framework or structure is designed to improve health outcomes and reduce plan costs. Undercoding or overcoding can lead to potential penalties and fines. To avoid this pitfall, seek clarification from the provider or get help from supervisors and auditors.
These are a few to mention. Some more include – misinterpretation of modifier guidelines, insufficient documentation, ignoring coding guidelines and more.
It’s not just hospitals that gain benefits. Everyone is in the loop, be it healthcare providers, insurance providers, patients, researchers, or healthcare organisations.
Medical coding is complex. One mistake can take you to rejection of reimbursement. Claim denials are prevalent and cause financial strain. Don’t dent your revenue cycle; get help from Akshar MediSolutions.
