The next day the older daughter said to the younger, “Last night I slept with my father. Let’s get him to drink wine again tonight, and you go in and sleep with him so we can preserve our family line through our father.” So they got their father to drink wine that night also, and the younger daughter went in and slept with him.

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)

v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite

All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.

Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.

New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.

I'm not even dreading writing basic syntax highlighting!

Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.

Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.

Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.

Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).

Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.

The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.

I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.

Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.

I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.

Turns out composition over inheritance won't save you from downcast hell, it just becomes `_ => abort()` hell.

Design in Motion: Real-Time Rendering's Impact on Architecture

Architecture, a discipline that once relied heavily on blueprints, models, and lengthy render times, has undergone a revolutionary transformation in recent years. The advent of real-time rendering technology has fundamentally altered the way architects visualize, present, and interact with their designs. This paradigm shift has not only enhanced the creative process but has also empowered architects to make more informed decisions and create immersive experiences for clients and stakeholders.

Real-time rendering, a technological marvel that harnesses the power of high-performance graphics hardware and advanced software algorithms, allows architects to generate photorealistic visualizations of their designs in a matter of milliseconds. Gone are the days of waiting hours or even days for a single rendering to complete. This acceleration in rendering time has not only expedited the design process but has also encouraged architects to explore multiple design iterations rapidly.

One of the most significant impacts of real-time rendering on architecture is the ability to visualize a design in various lighting conditions and environmental settings. Architects can now instantly switch between daytime and nighttime lighting scenarios, experiment with different materials, and observe how their designs respond to different seasons or weather conditions. This level of dynamic visualization offers insights into how a building's appearance and functionality evolve throughout the day, contributing to more holistic and thoughtful design solutions.

Moreover, real-time rendering has transformed client presentations. Architectural concepts can now be communicated with unprecedented clarity and realism. Clients can virtually walk through spaces, observing intricate details, exploring different angles, and even experiencing the play of light and shadow in real-time. This immersive experience fosters a deeper understanding of the design intent, enabling clients to provide more targeted feedback and make informed decisions.

The impact of real-time rendering on collaboration within architectural teams cannot be overstated. Traditionally, architects and designers would need to wait for a rendering to complete before discussing design changes or improvements. With real-time rendering, team members can make adjustments on the fly, observing the immediate effects of their decisions. This seamless collaboration not only enhances efficiency but also encourages interdisciplinary collaboration as architects, engineers, and other stakeholders can work together in real-time to refine designs.

The integration of virtual reality (VR) and augmented reality (AR) into the architectural workflow is another transformative aspect of real-time rendering. Architects can now create VR environments that allow clients to step inside their designs and explore every nook and cranny. This not only enhances client engagement but also enables architects to identify potential design flaws or spatial issues that might not be apparent in 2D drawings. AR, on the other hand, overlays digital information onto the physical world, facilitating on-site decision-making and construction supervision.

Real-time rendering's impact extends beyond the design phase. It has proven to be a valuable tool for public engagement and community involvement in architectural projects. By creating virtual walkthroughs of proposed structures, architects can offer the public an opportunity to experience the design before construction begins. This transparency fosters a sense of ownership and allows for constructive feedback, contributing to the development of designs that resonate with the community's needs and aspirations.

The environmental implications of real-time rendering are also noteworthy. The ability to visualize designs in various environmental contexts contributes to more sustainable architecture. Architects can assess how natural light interacts with interior spaces, optimizing energy efficiency and reducing the need for artificial lighting during the day.

In conclusion, real-time rendering has ushered in a new era of architectural design, propelling the industry into a realm of dynamic visualization, immersive experiences, and enhanced collaboration. The ability to witness designs in motion, explore different lighting conditions, and interact with virtual environments has redefined how architects approach their craft. From facilitating client presentations to fostering sustainable design solutions, real-time rendering's impact on architecture is profound and multifaceted. As the technology continues to evolve, architects have an unprecedented opportunity to push the boundaries of creativity, efficiency, and sustainability in the built environment.

I'm a Newbie to networking, and currently trying to understand this Network and Identifying the IPs for which interfaces.

I'd love to know which IP address is for the captured Router interface, etc. Which IP is the address of the captured interface n2.

How do I approach to solve this Problem?

I used to design and program these systems. Some of the first voice responsive ones. I’m so sorry for my crimes against humanity.

Swift 5.9 will get huge additions to the language, compared to the current version 5.8, including type safe and checked macros much like in Rust.
And it’s still not going to be a major version bump to 6.0!
I’m thrilled to see what kind of stuff will be in 6.0 then! 😄

This is cool as hell:

That is all.

does recursion have any practical use outside of being a cute/elegant solution under constraints where stack overflow isn't a concern due to small input size, and leetcode?

im having trouble thinking of anywhere you could justify using recursion in industry outside of leetcoding people

i assume the iterative approach would be preferred in scenarios where scaling matters

Windows 10 forces Chrome & other browsers to perform slow and laggy so that dumbass people can start switching to their fucking Edge.

Anyone know of any companies/agencies that are looking for freelance technical writers, for blog posts and such?

Mainly within the areas of DevOps, CI/CD, Kubernetes, bash etc.

Guys...watch the cppcon21 keynotes.
That is good stuff.

The insights and ideas in these talks are not just for c++. They apply to CS in general.

The presenters have done a phenomenal job with the content. There is a good deal of philosophy for what it means to code and how it should look like (not specifically in c++). Most of it is distilled insights collated right from the times when computer science was a domain of mathematicians and ee majors to the modern age.
It is like Dr.Dobbs but in video. Even book like. Certainly very dense.

A puzzle, just for fun.

Two friends, (a)lice and (b)ob are communicating through a channel encrypted with random numbers XOR'd together, like so:

keyA = randint(1024, 1024**2)
keyB = randint(1024, 1024**2)

msg = randint(1024, 1024**2)

You, an interloper, have watched all these communications, siphoning the packets as they went.

When alice sends a message to bob's mailbox, she does it like so:

mailBoxB = keyA^msg

Bob's mailbox receives the mail automatically, and applies his own key, sending it back to alice's mailbox:

mailBoxA = keyB^mailBoxB

Next, Alice's mailbox notices the message, and automatically removes her key and sends it back to bob's mailbox. All of this, the first message, the second, and the third, happens in milliseconds, the back and forth.

mailBoxB2 = mailBoxA^keyA

Finally, bob's mailbox removes his key, and deposits the now unencrypted message in his box, for him to read in the morning:

mailBoxBFinal = mailBoxB2^keyB

As as a spy, you know the first packet sent to bob, had a value of 589505.

The packet bob sent back to alice, after applying his key, has a value of 326166

The message sent *back* to bob after alice removed *her* key, had a value of:
576941

What are the values of keyA, keyB, and what is the value of the msg?

New useless information unlocked

Is this normal?

"not boolean" statement can be written as "(boolean+(-1))**2". Pls comment a better alternative lmao

soooo Texas froze before Hell, thought it was never going to happen but it did 🥴

Had a meeting scheduled for today, but since my employees (crucial for the meeting) do not have power I had to reschedule.

VP: I saw that you cancelled the meeting
Me: yes I did sir, my people do not have power at their homes so I decided that we can postpone it for later.

VP: Understandable, I just wanted to see if you guys were ok.

Me: yes sir, we are thank you and yourself?

The rest of the conv was standard pleasantries.

Why can't it be like this for all devs around the world?

Unicode I love you!

A while back, I had a lot of telemarketers were calling me daily, and I mean A LOT of them.

I got so frustrated with he calls that I decided I had to figure out a better way to handle those calls.

At the time, I was working with a PBX software called Asterisk, which is used to handle hardware interfaces and network applications for phone calls.

I needed a suitable side project and there was a version of Asterisk designed for Raspberry Pi, so I made a fun little answering service for myself.

Whenever a telemarketer called, I asked them to call back later, but to "my personal number", and gave them the number to my phone robot. (which had a pre-paid SIM card in a GSM dongle mounted)

When it received a call, it would play a pre-recorded phrase, wait for 1000 ms of silence and then play the next phrase.
After all 16 phrases had been played, it would start from phrase 7 again and repeat until the caller gave up.

I had this set up running for a while, and then added another robot for english speaking callers.

The calls stopped after a few months.
MISSION ACCOMPLISHED!

Found this little gem in the AMD64 reference manual:

"When PCIDs are enabled the system software can store 12-bit PCIDs in CR3 for different address spaces. Subsequently, when system software switches address spaces (**by writing the page table base pointer in CR3[62:12]**), the processor **may use TLB mappings previously stored for that address space and PCID**".

later:

"Updates to the CR3 register cause the entire TLB to be invalidated except for global pages."

So let me get this straight: PCIDs allow you to reuse TLB entries (instead of flushing the entire TLB) when writing a new address space to CR3 but writing to CR3 always flushes the entire TLB anyways

Just why 🤦‍♂️

Sometimes your day is going really nice, and you just had a nice cup of tea with the milk from the best cow on the farm. You're coding happy, and you will take a walk after that. Then, suddenly, you type `git checkout .` rather than `git reset HEAD .` and your life is miserable now.

Ok now I'm gonna tell you about my "Databases 2" exam. This is gonna be long.

I'd like to know if DB designers actually have this workflow. I'm gonna "challenge" the reader, but I'm not playing smartass. The mistakes I point out here are MY mistakes.

So, in my uni there's this course, "Databases 2" ("Databases 1" is relational algebra and theoretical stuff), which consist in one exercise: design a SQL database.

We get the description of a system. Almost a two pages pdf. Of course it could be anything. Here I'm going to pretend the project is a YouTube clone (it's one of the practice exercises).

We start designing a ER diagram that describes the system. It must be fucking accurate: e.g. if we describe a "view" as a relationship between the entities User and Video, it MUST have at least another attribute, e.g. the datetime, even if the description doesn't say it. The official reason?

"The ER relationship describes a set of couples. You can not have two elements equal, thus if you don't put any attribute, it means that any user could watch a video only once. So you must put at least something else."

Do you get my point? In this phase we're not even talking about a "database", this is an analysis phase.

Then we describe the type dictionary. So far so good, we just have to specify the type of any attribute.

And now... Constraints.
Oh my god the constraints. We have to describe every fucking constraint of our system. In FIRST ORDER LOGIC. Every entity is a set, and Entity(e) means that an element e belongs to the set Entity. "A user must leave a feedback after he saw a video" becomes like

For all u,v,dv,df,f ( User(u) and Video(v) and View(u, v, dv) and feedback(u, v, f) ) ---> dv < df

provided that dv and df are the datetimes of the view and the feedback creation (it is clear in the exercise, here seems kinda cryptic)

Of course only some of the constraints are explicitly described. This one, for example, was not in the text. If you fail to mention any "hidden" constraint, you lose a lot of points. Same thing if you not describe it correctly.

Now it's time for use cases.
You start with the usual stickman diagram. So far so good.
Then you have to describe their main functions.

In first order logic. Yes.

So, if you got the point, you may think that the following is correct to get "the average amount of feedback values on a single video" (1 to 5, like the old YT).
(let's say that feedback is a relationship with attribute between User and Video

getAv(Video v): int
Let be F = { va | feedback(v, u, va) } for any User u
Let av = (sum forall f in F) / | F |
return av

But nope, there's an error here. Can you spot it (I didn't)?

F is a set. Sets do not have duplicates! So, the F set will lose some feedback values! I can not define that as a simple set!

It has to be a set of couples, like (v, u), where v is the value and u the user; this way we can have duplicate feedback values in our set.

This concludes the analysis phase. Now, the design.

Well we just refactor everything we have done until now. Is-a relations become relationships, many-to-many relationships get an "association entity" between them, nothing new.
We write down on paper every SQL statement to build any table, entity or not. We write down every possible primary key or foreign key. The constraint that are not natively satisfied by SQL and/or foreign keys become triggers, and so on.

This exam is considered the true nightmare at our department. I just love it.

Now my question is, do actually DB designers follow this workflow? Or is this just a bloody hard training in Pai Mei style?
