] | I think that you can make your own cheaper Yama cold brew tower however what they are selling to you is the design! What you see in the picture is not chemistry glassware but if you want to make your own with chemistry glassware (this will cost more money because good chemistry glassware is purer and must have many expansive features that normal glassware don't have) I've written the analogous components in the figure. You need an open-top cylindrical dropping funnel with a [stopcock](http://en.wikipedia.org/wiki/Stopcock) valve.
See [here](http://www.pltscientific.com/catalog/attachment/files/1352702523-reaction-vessels-1.pdf) and [here](http://www.alibaba.com/product-detail/Dropping-Funnels-_136154108.html) for reference. You can use a normal funnel and attach to it a stopcock valve if you want. Then there is something similar to a Buchner funnel, I imagine that there is a filter in the bottom, may be included into the funnel, in this case, a 90-150 micron filter should be sufficient. See [here](http://www.piscolabglass.com/sintered-glass-buchner-funnel.htm) for more info. Then there is a glass coil spiral, up to my knowledge this has no practical use is only beautiful and geeky but will cost a lot. Then you have a normal carafe.
(probably a piece of filter paper is placed over the grounded cafe to allow the diffusion of water in the whole volume of the cylinder and not only in the centre).
With some [filter paper](http://en.wikipedia.org/wiki/Filter_paper) and a couple of half cut plastic bottles you can do your Yama tower with less of 5 $: you can make a little hole in the screw cap of your first bottle to make drip the first funnel, and use a piece of filter paper in the second. If you want to use glassware don't use chemistry glassware you don't need it really, try to find normal glassware to adapt to your project and you can make your own cheaper and nice Yama tower. | No need for Pyrex this all occurs at room temp, replace the valve on any water dispenser with adjustable valve, set to drip. For the funnel, empty wine or liquor bottle, cut off bottom, you all set. For bottom flask, glass milk jug. Easily under $50 and two hours. |

I think you really can't go wrong with using the ASP.NET MVC framework with some DDD concepts tossed in. This of course may be over architecting a small problem however let me suggest why I like it so much. With ASP.NET MVC you don't have any heavy obstacles to worry about ...just nice pure HTML. Form there following a good domain driven design you can quickly get some layers running. Plug in LINQ to SQL and you are off and running. With the MVC framework you can also easily make just about everything test driven which will help to keep the site maintainable over time.
I have written a whole series on DotNetSlackers regarding architectural concerns in ASP.NET MVC from a simple app all the way back to a complex distributed SOA style application. I have one more article (covering the SOA portion) to go to complete the series but there are many other articles in this mini-series that you could get started with.
Take a look at the "[Three Tiers to MVC](http://dotnetslackers.com/projects/StackOverflowInspiredKnowledgeExchange/)" section on this TOC of the bigger series
If this really is an admin site that you are creating though...do take a look at the Dynamic Data option. Very powerful! |

A more proper statement would probably be: "If we only allow finite volumetric charge densities, electric field lines cannot be discontinuous." | An electrostatic field line represents the actual path travelled by a unit positive charge in an electric field. If the line have sudden breaks it means the unit positive charge jumps from one place to another which is not possible.

1. If you need to scroll the screen to read one method, you need to split it
2. IF you have deja vue (the code you write seems familiar) you are probably repeating yourself, which means you should us an existing function/method and not write a new one.
3. No more than two constructs deep
for(...)
for(...)
for(...) BAD
4. No more than one loop in a row (one after the other).
5. If you need to return more then one type of data (a null/false version is not) then you need to split something.

A lot of object oriented languages make all of there methods public (e.g. Objective-C) and so you would only want to create functions that are intended to be called by other objects. On the other hand many languages like Java provide private functions which support the concept of grouping blocks of code into private functions that aren't really meant to be used outside of the class itself. |

>
> Chapter 4: Functions

>
> Functions should be short and sweet, and do just one thing. They should fit on one or two screenfuls of text (the ISO/ANSI screen size is 80x24, as we all know), and do one thing and do that well.
>
>
> The maximum length of a function is inversely proportional to the complexity and indentation level of that function. So, if you have a conceptually simple function that is just one long (but simple) case- statement, where you have to do lots of small things for a lot of different cases, it's OK to have a longer function.
>
>
> However, if you have a complex function, and you suspect that a less- than-gifted first-year high-school student might not even understand what the function is all about, you should adhere to the maximum limits all the more closely. Use helper functions with descriptive names (you can ask the compiler to in-line them if you think it's performance-critical, and it will probably do a better job of it that you would have done).
>
>
> Another measure of the function is the number of local variables. They shouldn't exceed 5-10, or you're doing something wrong. Re-think the function, and split it into smaller pieces. A human brain can generally easily keep track of about 7 different things, anything more and it gets confused. You know you're brilliant, but maybe you'd like to understand what you did 2 weeks from now.

10,546,141 | I have a great deal of RDF data to be inferred, and I need to develop my own inference rules. My question is that whether there is any method to do this?
Is it ok to use Jena rule and SPARQL to do so? Do the Jena rule and sparql query have to load all data into memory?
Wish to get answers soon and thanks in advance! | 2012/05/11 | [

] | The Jena [inference engines](http://jena.apache.org/documentation/inference/index.html) definitely work best when all of the data is loaded into memory. This is because, while it is possible to connect an inference engine to any Jena `Model`, including a persistent store such as [TDB](http://jena.apache.org/documentation/tdb/index.html), the inference algorithms make *many* calls to check the presence or absence of a particular triple in the model. This just gets inefficient when that check requires hitting disk.
If you have relatively straightforward inference requirements, you may be able to express your entailments via carefully constructed SPARQL queries, in which case you can probably get away with querying a TDB or SDB store directly. It just depends on the complexity of the query.
If the contents of your triple store are reasonably stable, or can be partitioned into a stable, persistent set and a dynamic in-memory set, then a strategy is to pre-compute the inference closure and store that in a persistent store. The classic space/time trade-off, in other words. There are two ways to do this: first, use the inference engine with an in-memory store using as much heap space as you can give it; second use Jena's [RIOT infer command-line script](http://jena.apache.org/documentation/io/riot.html#inference).
For large-scale RDF inferencing, an alternative to the open-source Jena platform is the commercial product [Stardog](http://stardog.com/) from Clark & Parsia (which I believe has a Jena model connector, but I haven't used it myself). | In addition to what Ian said and depending on your rules, if materializing all inferred triples is feasible in a streaming fashion in your case, have a look at RIOT's infer source code and, if you need more than RDFS, think how you might add support for a subset of OWL. You find the source code here:
* <https://svn.apache.org/repos/asf/jena/trunk/jena-arq/src/main/java/riotcmd/infer.java>
* <https://svn.apache.org/repos/asf/jena/trunk/jena-arq/src/main/java/org/openjena/riot/pipeline/inf/InferenceSetupRDFS.java>
* <https://svn.apache.org/repos/asf/jena/trunk/jena-arq/src/main/java/org/openjena/riot/pipeline/inf/InferenceProcessorRDFS.java>
The approach of RIOT's infer command can also be used with MapReduce, you can find an example here:
* <https://github.com/castagna/tdbloader4/blob/f5363fa49d16a04a362898c1a5084ade620ee81b/src/main/java/org/apache/jena/tdbloader4/InferDriver.java> |

However, more useful is to ask why you have this scenario. Perhaps you can explain further? | UML is all about communicating a design decision to those that need to know is clear and concise manner. If it is advantageous to the clarity of this aim then using an actor to represent a sub part of the design then do it. So long as you make it very clear that this is what you are communicating and that both are part of the same model.
As an example: I have experience in designing and coding embedded systems where blocks of code might be running on different processors/controllers or even in a different enclosure. But they are all part of the same application and therefore design model. Another way of looking at it on say, a windows machine, is an application that relies on a windows service for it's normal operation. The service might be an actor to the GUI application and the application might be an actor to the service.
@sfinnie is right in principle, it is sometimes useful to communicate things outside of this rule. After all, you'll never have to compile your UML, just explain it ;) . |

It is distributed via [the Microsoft/Xbox store](https://www.xbox.com/en-us/games/store/Minecraft-for-Windows/9NBLGGH2JHXJ). Not a downloadable `.exe`. So you can't download that version for Ubuntu.

I'm somewhat confused by exactly what you're asking, but I'll do my best to clarify.
Regarding the rest of your question, I mean the game costs money for the game. I.e., it isn't free. That's what costs money - the game.
I'm not sure that you're statement of "the betas are foc" is correct. As far as I'm aware, beta/preview versions of Minecraft aren't free and require you to own the game.
If I misunderstood and you you mean the Demo version of the game, I'm not sure if you can run that on Ubuntu (that would be a separate question, though). | Seems like a simple misunderstanding.
Microsoft (Mojang) charges for player accounts that use the client launcher (including single-player mode).
However, multiplayer servers --like the Minecraft Java Server-- are distributed and licensed for use free of charge.
Client = Proprietary/Paid.
Server = Proprietary/Free-of-charge.
In this case, A assumes you are treating both Client and Server as a single system (paid), while B assumes server alone (free).
A + B = misunderstanding. |

There are plenty of other books out there: check SO for questions on e.g. [general programming books](https://stackoverflow.com/questions/1711/what-is-the-single-most-influential-book-every-programmer-should-read) and [OO books](https://stackoverflow.com/questions/2064154/book-about-oo-in-practice). | If you are having a problem with identifying the real classes, then do "Noun analysis" - this will give you a hint on what are the classes going to be. Following that do "verb analysis" which is how the classes interact and relate - this will help you on associations and dependencies between classes and sub systems.

It will move workflows between site colelctions. | If the workflow was created via SharePoint Designer, I don't know of any way to "migrate" or reuse it without either breaking it in some way, or paying for a 3rd-party tool. I've tried free tools that help fix the GUIDs, but they don't seem to fix the workflows reliably. I've ended up having to recreate those workflows from scratch.
The best thing to do is package it as a wsp as Toni says above. Another great tool is Nintex - it's all WYSIWYG in-browser, and you can save workflows as templates & re-use them anywhere (though it's not cheap). |

You could get a board that is wider than the window, and at least 2/3 as tall as your back, and stand it up on one edge with both ends safely\* leaning on the window frame. Then you lean against that instead of leaning against the glass.

\*I'm not sure how safe this really is, but it's probably a whole lot safer than leaning against a pane of glass! | **TL;DR;**
"*Generally*" speaking, it's "*probably*" ok, but in terms of your safety my official response is "it's impossible to tell without a *lot* more info".
---
It being "safe" depends on:
* Window type - double or single glazed, or more
* Window structure - wooden, PVC, metal
* Window age and condition - is it strong, new, or old and deteriorated
* How the window is fitted - bars/supports from the window structure
running into the walls, or just fasteners, and how strong they are
(or are *not*)
* How much of you is pressing against the window or window frame
* Which part of the window you lean on - the glass or frame or
combination, or if partly the window sill
* How long you lean on it for
* Do you lean back hard, or gently
* Probably others
Also relevant in terms of safety, is how far you have to fall if something did happen. *It's never going to be good going through a window*, but there is a difference in "risk" between falling 10 or 15 feet down from a house height versus a high rise and 50+ feet down. Neither is good, but there is a difference.
If the window is stable and not old and deteriorated, and fastened well, you are *likely* to be safe.
*However* without physical evaluation it's hard to say, because of all the above mentioned points. Also, windows are not designed to be leaned on, certainly not over long periods as an ongoing support.
Fashioning something to make it safer would likely entail putting something across the frame on one side and the frame on the other, and leaning on that. As then your weight is spread across the frame, rather than pressing on one single point, and certainly not on the glass itself.
But this only reduces potential problems from not leaning directly on glass, and if the frame itself is weak then this will not be any safer.
In conclusion
-------------
It's hard to say over the internet how strong a structure is without knowing anything about it, or how old it is (etc - as per above list).
Deterioration is caused by various factors, which can vary or change depending on age, original build quality, and even things like your location - such as the weather (if you get lots of snow for example and you have wooden windows and don't maintain them regularly - etc).
Personally, I'd recommend avoiding it if you can. Shuffle your room around so you are leaning on a wall, or fasten a board to the wall below the window which comes up to the height you are leaning (which may not be ideal is it will likely cover the window and you lose light and window access etc). |

As this is something that is not checked in the typical tests, and most developers aren't looking for these kind of defects, it's one of those little strange things that finds its way into the final release.
It's not a priority bug and probably nobody reported it, so no developer has picked it and solved it. | This is super-quirky, but if make a custom group out of a single node, inputs and outputs are automatically connected, but you can control the order of inputs using the *Group Input* node - for example, if you want the *Scale* and *Detail* of *Noise Texture* to be last:

I see you've planned to have 177.5V across and 6mA through R1.
You can parallel 5 resistors that will take 1.2mA each.
177.5V / 1.2mA gives 147916 ohms, probably 150k ohms will be close enough. Then put 5 of them in parallel. The overall resistance will work out to 30k ohms (150k / 5).
Note that 1/4W resistors, even though they're rated for 1/4W, can still get rather hot when dissipating 1/4W, enough to burn you. Make sure to leave room in between for airflow (don't just bunch them all up together).
Also note that you probably won't be able to turn the anode off with this circuit. And if you do manage to turn it off, your Arduino will be fried. | Yes, you can make a high power resistor from multiple low power ones.
The simplest way to do this is to put them all either in series or all in parallel. With N resistors in series, make each 1/N the total desired resistance. Similarly, with N resistors in parallel, make each N times the desired resistance.
You aren't limited to only series or only parallel, but then computing the final resistance is a little more complex. If you don't make all the resistors equal and all in series or parallel, the resistors may not be sharing the power equally. That's OK, but must be taken into account to guarantee that no individual resistor has its power rating exceeded.
A simple trick is to put two of the desired resistances in parallel. That makes half the desired resistance. Now put two of those parallel combinations in series. That doubles the result, so you're back to the original resistance. Here is a diagram of this:

If R1 thru R4 are the same, then the resulting composite resistor is also that same value, but with 4x the power capability. |

This is about parenting... from the son's perspective.

Now, the main problem is that I am already "engaged" to someone. We are in a relationship since 5 years, but we don't want to officially marry until we are established in our careers.

] | This is a very challenging situation: your parents hold beliefs that you do not share. You're not going to change them and they're not going to change you (most likely anyway.)
It's most likely that you will simply have to deal with the situation, kindly explaining to the women they send your way your true situation. They, in turn, will have to deal with your take on life. They may not like it and depending on how rigid they are in their beliefs, may develop some strong emotions about it, but in the end they cannot force you to do what you don't want to do.
I'd suggest that, if you have not already, you politely explain your view of things. Once will be enough and don't expect immediate acceptance (unless you're lucky).
I wish I could give you more comforting advice, but I hope it is in some form helpful.
One final thought: never hold a grudge against them as this is how they were raised and part of their core beliefs. They may change at some point in the future and then you definitely want them an active part of your life. | Ask each of them separately "what would you have done and told your parents if they said didn't want you to be with dad/mom"?
I have little confidence in this to actually change their views, but hopefully that should at least make it clear that your mind is set. |

] | If any single game process can eat up all the memory or CPU, this isn't scalable. If your server is an 8-core machine, eight games can take all of the CPU time, there's nothing you can do, except for monitoring processes via `top` and killing them as needed - but that would make for a bumpy server.
Now, if you manage to prevent this stuff in the first place (sounds like a better idea to me), it *is* viable. Each process will take upwards of 30mb of memory, so you'll need a beefy server for every couple hundreds. Look at <http://site.nodester.com> for an example, they seem to be running around 600 processes on a single machine. Their software stack is open source too: <https://github.com/nodester/nodester>
node v0.8 [will bring Isolates](https://github.com/joyent/node/issues/2133) (shared-nothing threads), which will probably use less resources than a child process.
A more "serious" solution to this would be using some kind of virtualization like [OpenVZ](http://openvz.org) that will allow you to set resource limits, then just keep a pool of virtual servers available, every game gets it's own. It's not as heavy as it looks, it's ~18mb overhead per server and you can host hundreds per machine, although it's a much more complex setup. | This is a hard question to answer, because we don't know what your game do ...

] | The short answer is no, it won't scale!
**The long answer**
Let's first look at scalability. I'm taking the definition proposed by [wikipedia](http://en.wikipedia.org/wiki/Scalability): "scalability is the ability of a system, network, or process, to handle growing amount of work in a graceful manner or its ability to be enlarged to accommodate that growth."
In case one of your processes can eat up as much CPU as it's granted by the scheduler ([More details on the linux scheduler](http://www.ibm.com/developerworks/linux/library/l-scheduler/)) your system won't scale in a "graceful manner"! So what you would need for scalability is a setup as proposed by Ricardo Tomasi above where every match would need it's own VM. But that's not graceful and taking cost into consideration this is no viable solution.
The problem why your system won't scale is the algorithm behind it, no architecture can fix that but the algorithm needs to be fixed.
Your options to fix the algorithm
* Try to use some blocking mechanism in the game loop
* Counters to detect infinite loops
* Build an event queue that has limited slots so that adding additional events will throw exceptions
* Use a time slots algorithm for your game loop somehow like every match can consume 1/count(matches) time of one node.js process (but avoid building your own scheduler)
And even when your algorithm is fixed, spawning a process for each match will eat up some MB of your limited RAM resource which is not graceful in the sense of scalability. | This is a hard question to answer, because we don't know what your game do ...

How many players can connect to a match?
What kind of database are you using? Does it have fast writes?
Restarting a process is the last solution, because if you have a game where everything should happen fast and you restart the process it will take a couple of seconds before the players reconnect to it.
I don't think one process per match is scalable, what happens when you have 50.000 matches at the same time for example? I would say that a better solution would be to group matches on a child process by 2 criteria:
a) by the match id (some kind of sharding algorithm)
b) if more and more players come popping up spin another process (or even more), based on the number of players.

] | If any single game process can eat up all the memory or CPU, this isn't scalable. If your server is an 8-core machine, eight games can take all of the CPU time, there's nothing you can do, except for monitoring processes via `top` and killing them as needed - but that would make for a bumpy server.
Now, if you manage to prevent this stuff in the first place (sounds like a better idea to me), it *is* viable. Each process will take upwards of 30mb of memory, so you'll need a beefy server for every couple hundreds. Look at <http://site.nodester.com> for an example, they seem to be running around 600 processes on a single machine. Their software stack is open source too: <https://github.com/nodester/nodester>
node v0.8 [will bring Isolates](https://github.com/joyent/node/issues/2133) (shared-nothing threads), which will probably use less resources than a child process.
A more "serious" solution to this would be using some kind of virtualization like [OpenVZ](http://openvz.org) that will allow you to set resource limits, then just keep a pool of virtual servers available, every game gets it's own. It's not as heavy as it looks, it's ~18mb overhead per server and you can host hundreds per machine, although it's a much more complex setup. | The short answer is no, it won't scale!
**The long answer**
Let's first look at scalability. I'm taking the definition proposed by [wikipedia](http://en.wikipedia.org/wiki/Scalability): "scalability is the ability of a system, network, or process, to handle growing amount of work in a graceful manner or its ability to be enlarged to accommodate that growth."
In case one of your processes can eat up as much CPU as it's granted by the scheduler ([More details on the linux scheduler](http://www.ibm.com/developerworks/linux/library/l-scheduler/)) your system won't scale in a "graceful manner"! So what you would need for scalability is a setup as proposed by Ricardo Tomasi above where every match would need it's own VM. But that's not graceful and taking cost into consideration this is no viable solution.
The problem why your system won't scale is the algorithm behind it, no architecture can fix that but the algorithm needs to be fixed.
Your options to fix the algorithm
* Try to use some blocking mechanism in the game loop
* Counters to detect infinite loops
* Build an event queue that has limited slots so that adding additional events will throw exceptions
* Use a time slots algorithm for your game loop somehow like every match can consume 1/count(matches) time of one node.js process (but avoid building your own scheduler)
And even when your algorithm is fixed, spawning a process for each match will eat up some MB of your limited RAM resource which is not graceful in the sense of scalability. |

* Use a process pool with a load balancing mechanism
* Use *ZeroMQ* or something similar to exchange message
+ you will need *a few communication channels* here
+ use *request/response* for handshaking and control
+ you can use *multicasting* for the main channel
+ you can also use *publish/subscribe* if you have specific use for it too
You'll probably need a master process to do balancing and control all of the processes, keep track of events etc. Using the actor model you can scale out across a network of machines and in fact you can even have peer-to-peer clusters if you desire to do so, might need to use RSA keys for authentication though. I'd recommend to start with a single master
just waiting for processes to connect, the implement the worker skeleton and see how to implement the control side of things. Stick to master with 2 workers for starters, it's simpler to debug.
For the web front end you can also use a proxy, such as *Nginx*, which will call the master and then the master will tell it where to direct the new client. I suppose you would need to implement a UI module and then use it from within the worker.
I mean that the master will present no UI, and your workers will listen on different ports, though *Nginx* will hide it away from the user (he will see no ports in the URL bar) and you could also implement a RESTful API on top of that too. |

One can better understand the components of Om by looking at the Tamil and Telugu symbols for it though all scripts focus on mainly the anusvāra and omit the makāra altogether, while yet pronouncing it as a makāra and omitting to pronounce the makāra in combination with the anusvāra. | The components of Om is explained very well in Shiva Puran.
"The syllable “A” came first from northern face; the syllable “U” from the western; the syllable “M” from the southern and the Bindu (dot) from the eastern face. The Nāda (mystical sound) came from the middle face. Thus the complete set cropped up in five-fold form. Then all of them united in the syllable of “Om”.
-from Shiv Puran, Vidyeswara Samhita, Chapter 10, verse 18,19.
"4. The syllable Om means an excellent boat to cross the ocean of worldly existence. [Pra=of the Prakṛti i.e. the world evolved out of it. Navam—Nāvāṃ Varam—an excellent boat]
5. Or Praṇava may mean: “there is no world for you” or it may mean “That which leads to salvation”.
6-8. Or it may mean “that which leads to new knowledge.” After annihilating all actions it gives the persons who repeat the mantra or worship, a fresh knowledge of the pure soul. This Praṇava is two-fold (1) the subtle (2) the gross.
9. The subtle one is of a single syllable where the constituent five syllables are not differentiated clearly. The gross one is of five syllables where all the constituent syllables are manifest.
10. The subtle one is for the liberated living soul (jīvanmukta). The need for the contemplation of the meaning through the mantra is only upto the destruction of the physical body.
11. When the body is destroyed he completely merges in Śiva undoubtedly. The mere repeater of the mantra attains the yogic communion with Śiva certainly.
12. A person who repeats the mantra thirty-six crores of times certainly attains the yogic communion. The subtle Praṇava is again two-fold—the short, and the long.
13-15. The long one is present in the heart of the Yogins alone—separately in the form of “A” syllable, “U” syllable, “M” syllable, Bindu and Nāda. It is endowed with all the digits of the time sound. Śiva, Śakti and their union are indicated by “M” syllable ramified into three and this is called the short subtle Praṇava. The short Praṇava shall be recited and repeated by those who desire their all sins annihilated."

One can better understand the components of Om by looking at the Tamil and Telugu symbols for it though all scripts focus on mainly the anusvāra and omit the makāra altogether, while yet pronouncing it as a makāra and omitting to pronounce the makāra in combination with the anusvāra. | OM is the Self, the Atman. Om is the means of liberation and freedom from the effects of ignorance.
OM is indivisible, consists of three letters: A, U, and M. Every letter has different significance and represents the conscious states. The three states are waking, dreaming, and dreamless sleep, respectively, as well as the physical, astral, and causal levels of existence. When AUM is uttered, all the various parts of the vocal organ needed for speaking are used. AUM is a word that includes all sounds.
[The significance of three letters; A, U, and M, in AUM](https://yogicank.com/category/scriptural-knowledge/)
The letter ‘A’:- The letter A denotes to waking state or Vaisvanara (quarters of Atman). Vaiswanara, the first state of Self as the universal person in the physical being, corresponds to the first letter–A. Through the Japa and meditation of Om, they master the material world and control learn to control the senses themselves. The desires of masters are fulfilled because they are connected with the essence of creation and get the realization power.
The letter ‘U’:- Taijasa, the Self as the universal person in the mental state, resembles the letter. Taijasa and the letter U both are views in the dream state. In this state, Taijasa grows in wisdom and intellect and is highly honored. Two qualities that a person possessed in this quarter are: –
A master of this state develops the knowledge of humanity and delivers the inner momentum to assist questing souls in accessing knowledge.
A master adheres to the quality to becomes one with all human beings in a sense, and the master is so attuned and comfortable with other humans that the other is virtually his own Self. This quality appears in the great saints and yogis. Whether a poor or a king approaches them, he feels that they are the dear and his own.
Om is the way to move the thoughts from the subconscious state to the conscious. Meditation on OM will empower the yogi to know all about himself and understands others as well. No one can fool him. Like, Sivananda Ji. He was always very kind and humorous, went right to the truth of things about people’s characteristics.
3.The letter ‘M’:- M is the state of deep sleep where neither desires any object nor sees any dream. And the third quarter is Prajna, whose sphere is dreamless sleep, the state of total bliss and happiness with satisfaction.

Namah Shivaay | OM is the Self, the Atman. Om is the means of liberation and freedom from the effects of ignorance.
OM is indivisible, consists of three letters: A, U, and M. Every letter has different significance and represents the conscious states. The three states are waking, dreaming, and dreamless sleep, respectively, as well as the physical, astral, and causal levels of existence. When AUM is uttered, all the various parts of the vocal organ needed for speaking are used. AUM is a word that includes all sounds.
[The significance of three letters; A, U, and M, in AUM](https://yogicank.com/category/scriptural-knowledge/)
The letter ‘A’:- The letter A denotes to waking state or Vaisvanara (quarters of Atman). Vaiswanara, the first state of Self as the universal person in the physical being, corresponds to the first letter–A. Through the Japa and meditation of Om, they master the material world and control learn to control the senses themselves. The desires of masters are fulfilled because they are connected with the essence of creation and get the realization power.
The letter ‘U’:- Taijasa, the Self as the universal person in the mental state, resembles the letter. Taijasa and the letter U both are views in the dream state. In this state, Taijasa grows in wisdom and intellect and is highly honored. Two qualities that a person possessed in this quarter are: –
A master of this state develops the knowledge of humanity and delivers the inner momentum to assist questing souls in accessing knowledge.
A master adheres to the quality to becomes one with all human beings in a sense, and the master is so attuned and comfortable with other humans that the other is virtually his own Self. This quality appears in the great saints and yogis. Whether a poor or a king approaches them, he feels that they are the dear and his own.
Om is the way to move the thoughts from the subconscious state to the conscious. Meditation on OM will empower the yogi to know all about himself and understands others as well. No one can fool him. Like, Sivananda Ji. He was always very kind and humorous, went right to the truth of things about people’s characteristics.
3.The letter ‘M’:- M is the state of deep sleep where neither desires any object nor sees any dream. And the third quarter is Prajna, whose sphere is dreamless sleep, the state of total bliss and happiness with satisfaction.

I think that there is an implied question "Is there some reason why you would not want ice cream?, because if there is no reason you should feel feel to go ahead."
Because the question is very abbreviated, it would be good to make the answer explicit. "Thank you, yes, actually I would like some." OR "Thank you, no, actually I don't like it very much" |
399,282 | We're currently developing a Spring application that uses jdbcTemplates for the repository.
We have a lot of functions that only require specific combinations of columns in our database. It would be wasteful to always fetch the entire objects. But separating the columns into their own table doesn't make sense semantically, due to other reasons.
The sheer amount of these queries means that to keep everything progressing efficiently, it would be nice to only query for the columns that I actually need. But solutions I find always end up creating a lot of specific objects just for that single purpose, which feels like it could get very high-maintenance keeping track of all those different objects. It also means hand-writing a lot of queries, and exposing the result objects through the service layer.
Using an object-oriented SQL framework doesn't really solve the problem. Writing a query that gets executed by the repository means we're just moving the issue a layer upwards.
My question is: Is there an established way or pattern to call on the repository, say what you need to be returned, read out those details (while still keeping type saftey!) without having to create countless new model classes or delivering partially filled models that could be misused because someone didn't pay attention? | 2019/10/03 | [

First I would question this. If your objects are well-designed and not too bloated, the performance and memory overhead of fetching them completely instead of getting them partially is often negligible for most real-world cases. The performance of SQL queries over a network are way more dependend on the number of roundtrips they cause than on the number of columns involved (often it does not even make a huge difference if a query returns 1, 10 or 30 columns, and interestingly, this is often true for the number of rows as well). Investing too much thought into getting only the columns required for certain cases is often just a form of premature optimization.
However, if you really know for sure - (and that means: after profiling!) - in your application that getting model objects partially, or querying tables partially will actually bring you a required performance benefit, then you need to design your repository interface in a way it allows to specify the columns to be queried (and construct the SQL query from that spec). Your model objects should have an extra boolean metadata field for each column which indicates if the column was loaded by the last query or not, and the repositories have to maintain this field accordingly. The "getter" method for each column then can throw an exception if another part of the program will try to access an unloaded column later.
If your data objects map to several parent-child tables and your goal is just to use partial loading for avoiding SQL joins, it is also possible to implement this concept of partially loaded objects in coarser granularity, where extra metadata fields only indicates which child tables are actually loaded and which not.
I don't know if there is an ORM or framework for your environment which supports this out-of-the-box (I guess jdbcTemplates does not), but as you asked for a non-ORM solution I guess you have to implement this concept by yourself either.
The alternative to filling your pre-existing model-objects partially is to have individual, dynamic objects generated automatically for each query. This works best if there is programming language support for this:
* as mentioned by @Euphoric, in C# LINQ can be utilized to generate objects of anonymous types for each query, which allows to create a type-safe solution
* also in C#, one could utilize the type `dynamic` for this (see, for example, how [the Micro ORM Dapper](https://github.com/StackExchange/Dapper#execute-a-query-and-map-it-to-a-list-of-dynamic-objects) supports this). This is not type-safe anymore, however.
* in almost any major language, query results could be (lists of) instances of dictionaries, where the keys are the column names and the values are the column values of each records (either as strings, or as objects encapsulating the basic scalar datatypes). This can be implemented easily in a generic fashion. Of course, this is even less type safe, but it is a solution which is quite common in many scripting languages. | In Spring Boot, you may have a look at the the Specification that is very powerful:

To that specification, you may look at the Spring Rest API Search. Its not possible to get away without writing at least entity objects, but passing it through the layers, is possible with it <https://www.baeldung.com/rest-api-search-language-spring-data-specifications> |

156,830 | Consider a scenario where a managed package is deployed and is used in a specific region **(Western region)**.Now a new customer in another region **(Eastern Region)** needs some core level changes in that module which wont be suited for western region.To handle this the planning is to have a separate Repository for eastern region make necessary changes and make the package from the Repository and for introduction of new improvements both repository (Eastern and western) needs to be synchronized periodically.

] | The exact tools that you're using will dictate the precise process, but the general idea is that you should be using three distinct code bases, not two. One is at the top of the hierarchy, which we'll call Core, which contains the central logic for the other two code bases, Eastern and Western. Any changes to Core should be synchronized to Eastern and Western, while changes to just Eastern or Western would not be synchronized back to Core. Core does not actually represent a necessarily "functional" version of your code base, but simply a template for the other two code bases to get updates from. The Eastern and Western code bases should refer to two separate managed packages as a matter of simplicity.
There's going to be downsides any way you look at it, but having three code bases is going to introduce a minimum number of headaches for developers, and having just one managed package for Eastern and one for Western is going to minimize the number of headaches for clients, except for the precious few that may decide they installed the wrong version for whatever reason. It would be theoretically possible to build a set of three managed packages, where a client would first install Core followed by either Eastern or Western, but it's rather difficult for developers to work with, and requires extra steps from clients to install. | Before embarking on the complexity of separate branches (including the pain of merging changes) and separate managed packages (two security reviews), I suggest you review what is common and what is different for the two regions. (And perhaps consider how many other regions there may be in the future.)
In software in general, many products come as a single "package" but can be configured to handle different regions and and alternate functionality. In a Salesforce app there are a wide variety of configuration mechanisms that can be used post-install and things like custom settings can be used within the package to swap functionality.
If the differences are limited, you might be able to decide to deliver a single managed package that is the result of everyone working on a single code base (the simplest arrangement) or the result of two "region" branches being merged into a single "head" branch. |

What I had realized on the experiential level,is that there is no where to go in meditation ,I am already there ,all what I need to experience ,I am already experiencing.I realized that each experience whatever it is can be an object of meditation , a door way to end suffering.....Now If I cannot reach a certain state then the reality is ,,**that I cannot reach it** :).. knowing that right know and meditating on this reality by itself solves the problem.The quality of not reaching you cannot accept, you have an attitude towards it.When you accept not reaching the state you will transcend this thought.Then the state will come out of no where,its a state of connection with existence.

What eventually worked for me is this:
Simply be present with what's actually happening, and be mindful of any thought that arises, any feeling, any subtle pushing, any subtle leaning in, any expectation, etc.
Once mindfulness touches these things, they lose their power and dissipate with your wise attention. See them, and upon seeing know they are not worth clinging to, they are impermanent, unsatisfying, and not you. They will fade on their own. Watching these objects rise and fall, you'll realize deeply that clinging to past or future experience is suffering. It's just another object to let go of.
In your next sitting, see if you can note the arising expectations. See with the lense of the Three Characteristics, and then letting go happens naturally.
Accept today's meditation as it is, there are no failed meditations. Surrender with Equanimity to all objects.
Another trick is overcome your attachment to piti. Once you are feeling good in meditation, reset, unplugging the rapture. Reinforce that getting lost in "good experiences" is just like being absorbed in a wandering mind. Return to your primary meditation object.
Do not stop within. Sharpen your mindfulness. Once reasonably still, increase your mindfulness power and see reality at a finer grain. With wise attention even expectations can be let go of.

In other words, you must understand how you view the world (i.e. you must understand "your" ideas, expectations, and beliefs about the world, its parts, the relation between its parts and your role in such framework) in order to comprehend what your values are. Your values are born from your world-view, and indicate the things/facts/entities/events/ideas that you consider worthwhile.
Once you undestand deeply this theory of how emotions work, then you can start to see how "our" will operates: we do things when we are convinced that effort is worth being invested in the things done.
Now, the next step is to "convince" your emotions and values about the importance of letting go. To do so, you have to integrate new information about the Dhamma, and why letting go is such and important part of the path. This information can be reached by your own constant reflection and thoughts; by studying the suttas; or by listening or reading from other students/disciples of the Buddhadhamma.
To being able to let go, first you have to learn, at least theoretically, that feelings, perceptions, and thoughts are not "yours", neither "you". They are, instead, just habitual mental patterns, born from ignorance (i.e., from ignoring the Dhamma). Once you stop identifying with feelings, perception and thoughts, you will be able to start seeing them just by what they are: inertial habits of thought. Then, letting go becomes the natural progression, almost a by-product of all previous reflection and learning.
This "by-product" is the result of various factors interacting with each other. How to cultivate such factors? The Noble Eightfold Path help us to train each one of them. The key idea to keep in mind is that the training is gradual and progressive. The release of the mind takes its time, and goes according to the effort put into the practice of the whole Eightfold Path. As your emotions get reasons and evidence of the truth behind the Buddhadhamma, then your deeds will gradually go towards where this new emotional evidence/inormation leads you: liberation.
In sum, to exert effort is to have the will to take some course of action. But to have that will, you must have conviction of the relevance of such course of action in which you'll put your effort. That conviction grows from progressive understanding of the Dhamma.
Because of all the above, it is said that Right View is the forerunnner of the practice. See [in this link](https://www.accesstoinsight.org/ptf/dhamma/sacca/sacca4/samma-ditthi/index.html) for more details.

] | Great question, one that I struggled with for years as well. The fact that you recognize this issue means that you are already well on your way, sadhu.
What eventually worked for me is this:
Simply be present with what's actually happening, and be mindful of any thought that arises, any feeling, any subtle pushing, any subtle leaning in, any expectation, etc.
Once mindfulness touches these things, they lose their power and dissipate with your wise attention. See them, and upon seeing know they are not worth clinging to, they are impermanent, unsatisfying, and not you. They will fade on their own. Watching these objects rise and fall, you'll realize deeply that clinging to past or future experience is suffering. It's just another object to let go of.
In your next sitting, see if you can note the arising expectations. See with the lense of the Three Characteristics, and then letting go happens naturally.
Accept today's meditation as it is, there are no failed meditations. Surrender with Equanimity to all objects.
Another trick is overcome your attachment to piti. Once you are feeling good in meditation, reset, unplugging the rapture. Reinforce that getting lost in "good experiences" is just like being absorbed in a wandering mind. Return to your primary meditation object.
Do not stop within. Sharpen your mindfulness. Once reasonably still, increase your mindfulness power and see reality at a finer grain. With wise attention even expectations can be let go of.
Sadhu & Good Luck.

-with Metta | Great question ,this is actually a fallacy that ,I myself experienced after reaching long periods of bliss during meditation .What you are experiencing is called rapture,you started off well in meditation without expectation then when the blissful feeling came, instead of meditating on it, you became enchanted by it and thus wanted to have it back but you cant have it because you started desiring it,falling back in the loop of desire> attachment> suffering.
What I had realized on the experiential level,is that there is no where to go in meditation ,I am already there ,all what I need to experience ,I am already experiencing.I realized that each experience whatever it is can be an object of meditation , a door way to end suffering.....Now If I cannot reach a certain state then the reality is ,,**that I cannot reach it** :).. knowing that right know and meditating on this reality by itself solves the problem.The quality of not reaching you cannot accept, you have an attitude towards it.When you accept not reaching the state you will transcend this thought.Then the state will come out of no where,its a state of connection with existence.
See the issue meditation is trying to solve is not to keep you in a spiritual high,but to make you less possessed by things as well as **not** making you disinterested in life.Thus if you totally accept life as it is ,with its bad states as well as its good then you have understood the way.

Although it's nice to have a clean windshield, the best time to clean a windshield is when it's dirty. Practice is kind of like that. We look for the things that cause suffering and renounce them. Here's [MN8](https://suttacentral.net/mn8/en/sujato):

1,605,171 | I am a computer science engineering student and I've been programming on the .NET Framework for 2-3 years but I haven't used Linux. I thought, for my final year project, a Linux distro would be good.
I was thinking of a few ways to implement it, when this crazy idea occurred to me:

This could be the weirdest question but please be give me a way if I am right in *asking* the question and correct me if am wrong. | 2009/10/22 | [

] | The CLR (aka .NET framework) has been implemented at least once on Linux, in Mono.
True, you could make a Linux distribution which ships Mono, or uses .NET for some of its startup scripts / daemons. That would be fine. Someone has probably already done this.
I don't see exactly what advantage trying to run managed code in the kernel would confer, probably none.

As transitioning from user space to kernel space comes at a cost, performance would actually get worse, unless you manage to run your whole application in kernel space.
Wouldn't wanna do a syscall every time I add something to a list, or check the length of a string. |
