The pg_visibility module provides a means for examining the visibility map (VM) and page-level visibility information of a table. It also provides functions to check the integrity of a visibility map and to force it to be rebuilt.
Three different bits are used to store information about page-level visibility. The all-visible bit in the visibility map indicates that every tuple in the corresponding page of the relation is visible to every current and future transaction. The all-frozen bit in the visibility map indicates that every tuple in the page is frozen; that is, no future vacuum will need to modify the page until such time as a tuple is inserted, updated, deleted, or locked on that page. The page header's PD_ALL_VISIBLE bit has the same meaning as the all-visible bit in the visibility map, but is stored within the data page itself rather than in a separate data structure. These two bits will normally agree, but the page's all-visible bit can sometimes be set while the visibility map bit is clear after a crash recovery. The reported values can also disagree because of a change that occurs after pg_visibility examines the visibility map and before it examines the data page. Any event that causes data corruption can also cause these bits to disagree.
Functions that display information about PD_ALL_VISIBLE bits are much more costly than those that only consult the visibility map, because they must read the relation's data blocks rather than only the (much smaller) visibility map. Functions that check the relation's data blocks are similarly expensive.
pg_visibility_map(relation regclass, blkno bigint, all_visible OUT boolean, all_frozen OUT boolean) returns record
Returns the all-visible and all-frozen bits in the visibility map for the given block of the given relation.
pg_visibility(relation regclass, blkno bigint, all_visible OUT boolean, all_frozen OUT boolean, pd_all_visible OUT boolean) returns record
Returns the all-visible and all-frozen bits in the visibility map for the given block of the given relation, plus the PD_ALL_VISIBLE bit of that block.
pg_visibility_map(relation regclass, blkno OUT bigint, all_visible OUT boolean, all_frozen OUT boolean) returns setof record
Returns the all-visible and all-frozen bits in the visibility map for each block of the given relation.
pg_visibility(relation regclass, blkno OUT bigint, all_visible OUT boolean, all_frozen OUT boolean, pd_all_visible OUT boolean) returns setof record
Returns the all-visible and all-frozen bits in the visibility map for each block of the given relation, plus the PD_ALL_VISIBLE bit of each block.
pg_visibility_map_summary(relation regclass, all_visible OUT bigint, all_frozen OUT bigint) returns record
Returns the number of all-visible pages and the number of all-frozen pages in the relation according to the visibility map.
pg_check_frozen(relation regclass, t_ctid OUT tid) returns setof tid
Returns the TIDs of non-frozen tuples stored in pages marked all-frozen in the visibility map. If this function returns a non-empty set of TIDs, the visibility map is corrupt.
pg_check_visible(relation regclass, t_ctid OUT tid) returns setof tid
Returns the TIDs of non-all-visible tuples stored in pages marked all-visible in the visibility map. If this function returns a non-empty set of TIDs, the visibility map is corrupt.
pg_truncate_visibility_map(relation regclass) returns void
Truncates the visibility map for the given relation. This function is useful if you believe that the visibility map for the relation is corrupt and wish to force rebuilding it. The first VACUUM executed on the given relation after this function is executed will scan every page in the relation and rebuild the visibility map. (Until that is done, queries will treat the visibility map as containing all zeroes.)
By default, these functions are executable only by superusers.

Apache HTTP Server Version 2.4
| Description: | Basic (required) security for Unix-family platforms. |
|---|---|
| Status: | Base |
| Module�Identifier: | unixd_module |
| Source�File: | mod_unixd.c |
| Description: | Directory for apache to run chroot(8) after startup. |
|---|---|
| Syntax: | ChrootDir /path/to/directory |
| Default: | none |
| Context: | server config |
| Status: | Base |
| Module: | mod_unixd |
| Compatibility: | Available in Apache 2.2.10 and later |
This directive tells the server to chroot(8) to the specified directory after startup, but before accepting requests over the 'net.
Note that running the server under chroot is not simple, and requires additional setup, particularly if you are running scripts such as CGI or PHP. Please make sure you are properly familiar with the operation of chroot before attempting to use this feature.
| Description: | Group under which the server will answer requests |
|---|---|
| Syntax: | Group unix-group |
| Default: | Group #-1 |
| Context: | server config |
| Status: | Base |
| Module: | mod_unixd |
The Group
directive sets the group under
which the server will answer requests. In order to use this
directive, the server must be run initially as root
. If
you start the server as a non-root user, it will fail to change to the
specified group, and will instead continue to run as the group of the
original user. Unix-group is one of:
#
followed by a group number.Group www-group
It is recommended that you set up a new group specifically for
running the server. Some admins use user nobody
,
but this is not always possible or desirable.
Don't set Group
(or User
) to root
unless
you know exactly what you are doing, and what the dangers are.
| Description: | Enable or disable the suEXEC feature |
|---|---|
| Syntax: | Suexec On|Off |
| Default: | On if suexec binary exists with proper owner and mode,
Off otherwise |
| Context: | server config |
| Status: | Base |
| Module: | mod_unixd |
When On, startup will fail if the suexec binary doesn't exist or has an invalid owner or file mode.
When Off, suEXEC will be disabled even if the suexec binary exists and has a valid owner and file mode.
| Description: | The userid under which the server will answer requests |
|---|---|
| Syntax: | User unix-userid |
| Default: | User #-1 |
| Context: | server config |
| Status: | Base |
| Module: | mod_unixd |
The User
directive sets the user ID as
which the server will answer requests. In order to use this
directive, the server must be run initially as root
.
If you start the server as a non-root user, it will fail to change
to the lesser privileged user, and will instead continue to run as
that original user. If you do start the server as root
,
then it is normal for the parent process to remain running as root.
Unix-userid is one of:
The user should have no privileges that result in it being
able to access files that are not intended to be visible to the
outside world, and similarly, the user should not be able to
execute code that is not meant for HTTP requests. It is
recommended that you set up a new user and group specifically for
running the server. Some admins use user nobody
, but
this is not always desirable, since the nobody
user
can have other uses on the system.
Don't set User
(or Group
) to root
unless
you know exactly what you are doing, and what the dangers are.

I bought a bottle from a company in New Jersey. The first thing I did upon receiving the bottle in the mail was to open a capsule and snort it. There are a lot of fillers in the mix, so it was a lot to put up there. There was no rush, no local numbness, nothing.
The next day, I took three (they contain 100mg each) and, after two hours or so, felt a nice very mellow stimulant feeling. The mood lift and expansiveness of cocaine or methamphetamine, but without the push. It lasted a few hours and faded away. This effect is consistent but inconvenient, given the very long delay in onset.
Later, I tried plugging it (ie in solution into the rectum) since that's as effective as snorting but can handle a lot more volume. I loaded 300mg into the (needleless!) syringe in 5ccs of water. But alas, nothing, not even the aforementioned warmth.
I threw out the rest of the bottle.

Automation 4 Lua Registration
From Aegisub Manual
Registration covers presenting your Automation 4 Lua script to Aegisub, providing information about it and registering what features it provides.
Contents |
Features explained
One of the primary concepts in Automation 4 is the feature. A feature is something a script makes available for Aegisub to call back in response to a user action.
A feature is not a plain callback. Rather, it's usually a set of several callback functions as well as some information on how they should be presented to the user in the GUI.
One feature is the macro. A macro is presented as an item in the Automation menu. A macro has a name (the title show in the menu), a description (the text shown on the status bar when hovering over the menu item), a processing function (the function called when the user selects the menu item) and an optional validation function (determines whether the macro can even do any work in the current state.)
Another feature is the export filter. The export filter is presented in the Export dialogue and can be applied during an export operation. Export filters also have a name, description, processing function and then an optional configuration panel provider. The configuration panel provider is a function that returns a configuration dialogue definition structure which will be displayed in the Export dialogue when the export filter is enabled. The settings filled into the configuration panel are passed to the processing function when it is run.
Script information globals
A script can set a few global variables to provide metadata about the script to Aegisub. The information given with these variables are displayed in the Automation Manager dialogue and the Script Info dialogue.
- script_name (string) - Name of the script, this should be short.
- script_description (string) - Description of the purpose of the script. Shouldn't be too long either.
- script_version (string or number) - Version numer/name of the script. This is freeform, no specific meaning is assigned to this.
- script_author (string) - Author credits for the script.
All of these are optional, a script does not have to provide any of these. If no script name is given, the file name is used instead for display purposes.
Registration functions
The registration functions are the functions provided by Automation 4 Lua you can call to make a feature available to Aegisub. You will usually call these in the top level, at the very bottom of your script.
aegisub.register_macro
Synopsis: aegisub.register_macro(name, description, processing_function, validation_function)
Register a macro feature.
- name (string) - The name displayed on the Automation menu. This should be very short, try three words or less, and should be in command tense.
- description (string) - The description displayed on the status bar when the user hovers the mouse over the menu item. This should be a concise description of what the macro does. Try to keep it at most 60 characters.
- processing_function (function) - The function that is called when the user selects the menu item. This must be a function with the macro processing function API.
- validation_function (function, optional) - This function is called to determine whether the menu item should be available to the user or not. (Grayed out or not.) If no validation function is provided the macro is always available. This function must follow the macro validation function API.
aegisub.register_filter
Synopsis: aegisub.register_filter(name, description, priority, processing_function, configuration_panel_provider)
Register an export filter feature.
- name (string) - The name displayed in the export filters list. The name should be rather short.
- description (string) - The description displayed in the description box when the user highlights the export filter in the Export dialogue.
- priority (number) - Determines the initial ordering of export filter application. Filters with higher priority are applied earlier than filters with lower priority. The user can change the filter application order in the Export dialogue. Priorities of the Aegisub built in export filters:
- Transform Framerate = 1000 (karaoke effects should have higher priority than this)
- Clean Script Info = 0 (your script might depend on the information cleaned by this)
- Fix Styles = -5000 (should almost always run last)
- processing_function (function) - The function that is called when the user initiates the export operation. This must be a function with the export filter processing function API.
- configuration_panel_provider (function, optional) - A function that provides a configuration panel for the export filter. If this function is not provided the export filter will not have a configuration panel. This function must follow the export filter configuration panel provider API.
Feature callback functions
These are the callback functions you provide to the registration functions.
Macro processing function
Signature: process_macro(subtitles, selected_lines, active_line)
Macro processing functions passed to aegisub.register_macro
must have this signature. The name process_macro
is a placeholder for your own function name.
Important, undo points: If you make any modifications to the subtitles data you must always set an undo point when finished, otherwise the undo system will become inconsistent and the user will find that the Undo function behaves wrong.
- subtitles (user data) - The subtitles object you use to manipulate the subtitles with.
- selected_lines (table) - An array with indexes of the selected lines. The values in this table are line indexes in the subtitles object at its initial state. Only dialogue class lines can ever be selected.
- active_line (number) - The line that is currently available for editing in the subtitle editing area. This is an index into the subtitles object.
Return value: The macro processing function can optionally return a new selected_lines
table, containing indexes of the lines that must be selected after the macro has returned.
Macro validation function
Signature: validate_macro(subtitles, selected_lines, active_line)
Macro validation functions passed to aegisub.register_macro
must have this signature. The name validate_macro
is a placeholder for your own function name.
Important, execution time: Validation functions should always run very fast. Do as little work as possible inside this function, because it is run every time the user pulls open the Automation menu, and every millisecond you spend in validate_macro
is one millisecond delay in opening the menu. Consider that the user might have very large files open. Don't block the UI.
- subtitles (user data) - The subtitles object for the current subtitle file, this is read-only, you cannot modify the subtitles in the validation function. Attempting to modify the subtitles will cause a run-time error.
- selected_lines (table) - An array with indexes of the selected lines. The values in this table are line indexes in the subtitles object at its initial state. Only dialogue class lines can ever be selected.
- active_line (number) - The line that is currently available for editing in the subtitle editing area. This is an index into the subtitles object.
Return value: Boolean, true
if the macro can run given the current state of subtitles, selected_lines and active_line, false
if it can not.
Export filter processing function
Signature: process_filter(subtitles, settings)
Export filter processing functions passed to aegisub.register_filter
must have this signature. The name process_filter
is a placeholder for your own function name.
You do not have to worry about undo issues with export filters. You always work on a copy of the subtitle file.
- subtitles (user data) - The subtitles object you use to manipulate the subtitles with. This is a copy of the open subtitles file, modifying this subtitles object does not modify the open file and will only affect the exported file.
- settings (table) - Configuration settings entered into the configuration panel or an empty table if there is no configuration panel. See the page on configuration dialogues for more information on the format of this table.
Return value: Nothing.
Export filter configuration panel provider
Signature: get_filter_configuration_panel(subtitles, old_settings)
Export filter configuration panel providers passed to aegisub.register_filter
must have this signature. The name get_filter_configuration_panel
is a placeholder for your own function name.
Important, execution time: This function is called automatically when the user opens the Export dialogue, and Aegisub blocks until it returns with a configuration panel. Consider that the user might have a very large file open, and that every millisecond spent creating your confituration dialogue is one more millisecond the user has to wait for the Export dialogue to open. Don't block the UI.
- subtitles (user data) - The subtitles object for the current subtitle file, this is read-only, you cannot modify the subtitles in the filter configuration provider. Attempting to modify the subtitles will cause a run-time error.
- old_settings (table) - Previous configuration settings entered into the configuration panel, if any. When an Automation 4 export filter is run, any configuration settings are automatically stored to the original file. If any stored settings exist for this filter, they are passed as old_settings so you can use them as a base for filling in defaults.
Return value: A configuaration dialogue table, see the page on configuration dialogues for more information on the format of this table.

What about:
Lean: 28f4143be31b7aa3c63a907be5443ca100025ef1 mathlib: d84af03bdb8ec4e02c96b6262e7b78c8f3de412b
Thanks
In the mean time I've found that March 27th nightly seems to allow compiling mathlib HEAD
But now rcases
doesn't work in my code
I see tactic.rcases_patt.has_reflect._rec_2: trying to evaluate sorry
each time I use rcases
Sorry
It's gone now
I missed one server restart
Sorry
I can't evaluate that
Now I need to figure out how wlog
is meant to be used
My naive attempt leads to failed to revert '_inst_3', it is a frozen local instance (possible solution: use tactic
tactic.unfreeze_local_instances to reset the set of local instances)
context is
X : Type, _inst_3 : topological_space X, f g : homeo X X, H : supp f ∩ supp g = ∅, x : X, h : x ∈ supp f ∪ supp g ⊢ (f ∘ g) x = (g ∘ f) x
I'm trying to use wlog
(without knowing anything about it, only hoping from the name) to say it suffices to prove the statement when x
is in the support of f
Is that instance used in your proof?
What proof?
I have no proof yet
(actually I have one but without wlog
)
Right ... and does the part that wlog
would replace make use of _inst_3
?
Of course
everything makes use of that
it's the topological space structure on X
https://github.com/PatrickMassot/lean-scratchpad/blob/master/src/support.lean#L133
It's curious because wlog
shouldn't need to revert anything but f
, g
, H
and h
Can you show me the command that you're using?
I'm trying to replace the proof with:
lemma fundamental' (f g : homeo X X) (H : supp f ∩ supp g = ∅) : f ∘ g = g ∘ f := begin funext, by_cases h : x ∈ supp f ∪ supp g, { wlog h : x ∈ supp f using x y, }, { replace h : x ∈ -(supp f ∪ supp g) := h, rw compl_union (supp f) (supp g) at h, have f_x : f x = x := compl_supp_subset_fix f h.1, have g_x : g x = x := compl_supp_subset_fix g h.2, exact calc (f ∘ g) x = f (g x) : rfl ... = f x : by rw g_x ... = x : by rw f_x ... = g x : by rw g_x ... = g (f x) : by rw f_x } end
I only remove everything inside the first branch of the by_cases
and wlog
there
Maybe I completely misunderstood what wlog
is meant to do
I also don't manage to change the topic of messages that should be elsewhere
How did you do that?
I went to one of my messages preceding most of this conversation, I changed its topic and selected the option "change the topic of everything that came later"
Maybe I completely misunderstood what
wlog
is meant to do
I think I misled you. Try wlog h : x ∈ supp f using f g
instead.
intron tactic failed, insufficient binders state: X : Type, _inst_3 : topological_space X, x : X, f g : homeo X X, this : ∀ (f g : homeo X X), x ∈ supp f → supp f ∩ supp g = ∅ → x ∈ supp f ∪ supp g → (f ∘ g) x = (g ∘ f) x, h : x ∈ supp f ⊢ homeo X X
Is that the only goal being printed?
yes
Ok I'm going to clone your repo and see what I can do
Thanks a lot!
No worries! I found a serious bug in wlog. I'll let you know when I figured out a fix. In the mean time, I hope this is not stopping you
No I'm not stopped, I have a working proof (with lot of duplication, hence I thought that would be a good opportunity to learn wlog
)
how is wlog now?
I don't really think one can use wlog
I mean, it passed those simple examples in the tests
Can you show what you tried?

… especially since pthreads (Mozilla pthreads, Chromium pthreads) and SIMD (simd.js, Chromium SIMD, simd.js in asm.js) are coming to JavaScript.
There are two main benefits WebAssembly provides:
The kind of binary format being considered for WebAssembly can be natively decoded much faster than JavaScript can be parsed (experiments show more than 20× faster). On mobile, large compiled codes can easily take 20–40 seconds just to parse, so native decoding (especially when combined with other techniques like streaming for better-than-gzip compression) is critical to providing a good cold-load user experience.
By avoiding the simultaneous asm.js constraints of AOT-compilability and good performance even on engines without specific asm.js optimizations, a new standard makes it much easier to add the features required to reach native levels of performance.
Of course, every new standard introduces new costs (maintenance, attack surface, code size) that must be offset by the benefits. WebAssembly minimizes costs by having a design that allows (though not requires) a browser to implement WebAssembly inside its existing JavaScript engine (thereby reusing the JavaScript engine’s existing compiler backend, ES6 module loading frontend, security sandboxing mechanisms and other supporting VM components). Thus, in cost, WebAssembly should be comparable to a big new JavaScript feature, not a fundamental extension to the browser model.
Comparing the two, even for engines which already optimize asm.js, the benefits outweigh the costs.
WebAssembly was designed with a variety of use cases in mind.
We think so. There was an early prototype with demos [1, 2], which showed that decoding a binary WebAssembly-like format into asm.js can be efficient. And as the WebAssembly design has changed there have been more experiments with polyfilling.
Overall, optimism has been increasing for quick adoption of WebAssembly in browsers, which is great, but it has decreased the motivation to work on a polyfill.
It is also the case that polyfilling WebAssembly to asm.js is less urgent because of the existence of alternatives, for example, a reverse polyfill - compiling asm.js to WebAssembly - exists, and it allows shipping a single build that can run as either asm.js or WebAssembly. It is also possible to build a project into two parallel asm.js and WebAssembly builds by just flipping a switch in emscripten, which avoids polyfill time on the client entirely. A third option, for non-performant code, is to use a compiled WebAssembly interpreter such as binaryen.js.
However, a WebAssembly polyfill is still an interesting idea and should in principle be possible.
As explained in the high-level goals, to achieve a Minimum Viable Product, the initial focus is on C/C++.
However, by integrating with JavaScript at the ES6 Module interface, web developers don’t need to write C++ to take advantage of libraries that others have written; reusing a modular C++ library can be as simple as using a module from JavaScript.
Beyond the MVP, another high-level goal is to improve support for languages other than C/C++. This includes allowing WebAssembly code to allocate and access garbage-collected (JavaScript, DOM, Web API) objects . Even before GC support is added to WebAssembly, it is possible to compile a language’s VM to WebAssembly (assuming it’s written in portable C/C++) and this has already been demonstrated (1, 2, 3). However, “compile the VM” strategies increase the size of distributed code, lose browser devtools integration, can have cross-language cycle-collection problems and miss optimizations that require integration with the browser.
WebAssembly initially focuses on C/C++, and a new, clean WebAssembly backend is being developed in upstream clang/LLVM, which can then be used by LLVM-based projects like Emscripten and PNaCl.
As WebAssembly evolves it will support more languages than C/C++, and we hope that other compilers will support it as well, even for the C/C++ language, for example GCC. The WebAssembly working group found it easier to start with LLVM support because they had more experience with that toolchain from their Emscripten and PNaCl work.
We hope that proprietary compilers also gain WebAssembly support, but we’ll let vendors speak about their own platforms.
The WebAssembly Community Group would be delighted to collaborate with more compiler vendors, take their input into consideration in WebAssembly itself, and work with them on ABI matters.
Yes! WebAssembly defines a text format to be rendered when developers view the source of a WebAssembly module in any developer tool. Also, a specific goal of the text format is to allow developers to write WebAssembly modules by hand for testing, experimenting, optimizing, learning and teaching purposes. In fact, by dropping all the coercions required by asm.js validation, the WebAssembly text format should be much more natural to read and write than asm.js. Outside the browser, command-line and online tools that convert between text and binary will also be made readily available. Lastly, a scalable form of source maps is also being considered as part of the WebAssembly tooling story.
Existing Emscripten users will get the option to build their projects to WebAssembly, by flipping a flag. Initially, Emscripten’s asm.js output would be converted to WebAssembly, but eventually Emscripten would use WebAssembly throughout the pipeline. This painless transition is enabled by the high-level goal that WebAssembly integrate well with the Web platform (including allowing synchronous calls into and out of JavaScript) which makes WebAssembly compatible with Emscripten’s current asm.js compilation model.
No! WebAssembly is designed to be a complement to, not replacement of, JavaScript. While WebAssembly will, over time, allow many languages to be compiled to the Web, JavaScript has an incredible amount of momentum and will remain the single, privileged (as described above) dynamic language of the Web. Furthermore, it is expected that JavaScript and WebAssembly will be used together in a number of configurations:
The LLVM compiler infrastructure has a lot to recommend it: it has an existing intermediate representation (LLVM IR) and binary encoding format (bitcode). It has code generation backends targeting many architectures is actively developed and maintained by a large community. In fact PNaCl already uses LLVM as a basis for its binary format. However the goals and requirements that LLVM was designed to meet are subtly mismatched with those of WebAssembly.
WebAssembly has several requirements and goals for its Instruction Set Architecture (ISA) and binary encoding:
LLVM IR is meant to make compiler optimizations easy to implement, and to represent the constructs and semantics required by C, C++, and other languages on a large variety of operating systems and architectures. This means that by default the IR is not portable (the same program has different representations for different architectures) or stable (it changes over time as optimization and language requirements change). It has representations for a huge variety of information that is useful for implementing mid-level compiler optimizations but is not useful for code generation (but which represents a large surface area for codegen implementers to deal with). It also has undefined behavior (largely similar to that of C and C++) which makes some classes of optimization feasible or more powerful, but which can lead to unpredictable behavior at runtime. LLVM’s binary format (bitcode) was designed for temporary on-disk serialization of the IR for link-time optimization, and not for stability or compressibility (although it does have some features for both of those).
None of these problems are insurmountable. For example PNaCl defines a small portable subset of the IR with reduced undefined behavior, and a stable version of the bitcode encoding. It also employs several techniques to improve startup performance. However, each customization, workaround, and special solution means less benefit from the common infrastructure. We believe that by taking our experience with LLVM and designing an IR and binary encoding for our goals and requirements, we can do much better than adapting a system designed for other purposes.
Note that this discussion applies to use of LLVM IR as a standardized format. LLVM’s clang frontend and midlevel optimizers can still be used to generate WebAssembly code from C and C++, and will use LLVM IR in their implementation similarly to how PNaCl and Emscripten do today.
Optimizing compilers commonly have fast-math flags which permit the compiler to relax the rules around floating point in order to optimize more aggressively. This can include assuming that NaNs or infinities don’t occur, ignoring the difference between negative zero and positive zero, making algebraic manipulations which change how rounding is performed or when overflow might occur, or replacing operators with approximations that are cheaper to compute.
These optimizations effectively introduce nondeterminism; it isn’t possible to determine how the code will behave without knowing the specific choices made by the optimizer. This often isn’t a serious problem in native code scenarios, because all the nondeterminism is resolved by the time native code is produced. Since most hardware doesn’t have floating point nondeterminism, developers have an opportunity to test the generated code, and then count on it behaving consistently for all users thereafter.
WebAssembly implementations run on the user side, so there is no opportunity for developers to test the final behavior of the code. Nondeterminism at this level could cause distributed WebAssembly programs to behave differently in different implementations, or change over time. WebAssembly does have some nondeterminism in cases where the tradeoffs warrant it, but fast-math flags are not believed to be important enough:
sin
, cos
, exp
,
pow
, and so on. WebAssembly’s strategy for such functions is to allow them
to be implemented as library routines in WebAssembly itself (note that x86’s
sin
and cos
instructions are slow and imprecise and are generally avoided
these days anyway). Users wishing to use faster and less precise math
functions on WebAssembly can simply select a math library implementation
which does so.add
,
sub
, or mul
they don’t have to worry about NaN for example doesn’t make
them any faster, because NaN is handled quickly and transparently in hardware
on all modern platforms.mmap
?The mmap
syscall has many useful features. While these are all packed into one overloaded
syscall in POSIX, WebAssembly unpacks this functionality into multiple
operators:
grow_memory
operator;0
to memory_size
.A significant feature of mmap
that is missing from the above list is the
ability to allocate disjoint virtual address ranges. The reasoning for this
omission is:
mmap
with what appears to be noncontiguous memory
allocation (but, under the hood is just coordinated use of memory_resize
and
mprotect
/map_file
/map_shmem
/madvise
).The benefit of allowing noncontiguous virtual address allocation would be if it allowed the engine to interleave a WebAssembly module’s linear memory with other memory allocations in the same process (in order to mitigate virtual address space fragmentation). There are two problems with this:
size_t
?The amount of linear memory needed to hold an abstract size_t
would then also
need to be determined by an abstraction, and then partitioning the linear memory
address space into segments for different purposes would be more complex. The
size of each segment would depend on how many size_t
-sized objects are stored
in it. This is theoretically doable, but it would add complexity and there would
be more work to do at application startup time.
Also, allowing applications to statically know the pointer size can allow them to be optimized more aggressively. Optimizers can better fold and simplify integer expressions when they have full knowledge of the bitwidth. And, knowing memory sizes and layouts for various types allows one to know how many trailing zeros there are in various pointer types.
Also, C and C++ deeply conflict with the concept of an abstract size_t
.
Constructs like sizeof
are required to be fully evaluated in the front-end
of the compiler because they can participate in type checking. And even before
that, it’s common to have predefined macros which indicate pointer sizes,
allowing code to be specialized for pointer sizes at the very earliest stages of
compilation. Once specializations are made, information is lost, scuttling
attempts to introduce abstractions.
And finally, it’s still possible to add an abstract size_t
in the future if
the need arises and practicalities permit it.
A great number of applications don’t ever need as much as 4 GiB of memory. Forcing all these applications to use 8 bytes for every pointer they store would significantly increase the amount of memory they require, and decrease their effective utilization of important hardware resources such as cache and memory bandwidth.
The motivations and performance effects here should be essentially the same as those that motivated the development of the x32 ABI for Linux.
Even Knuth found it worthwhile to give us his opinion on this issue at point, a flame about 64-bit pointers.
Yes but it will depend on the WebAssembly embedder. Inside a browser you’ll get access to the same HTML5 and other browser-specific APIs which are also accessible through regular JavaScript. However, if a wasm VM is provided as an “app execution platform” by a specific vendor, it might provide access to proprietary platform-specific APIs of e.g. Android / iOS.


`etsmgr' is a simple application that can act as the `heir' for ETS tables owned by other applications/processes. This allows the table owners to crash and restart without loosing the data stored in the table.
The implementation is inspired by the two blog posts from Steve Vinoski:
While adapting and embedding DeadZen's implementation , as referenced in the second article, would have sufficed, it was felt that a more generic and reusable approach would help future projects.
`etsmgr' can manage multiple ETS tables for multiple client processes.
Multiple instances of `etsmgr' can co-exist on the same node by starting the `etsmgr' applications with unique instance names.
An instance of `etsmgr' can run as a standalone application, or be embedded within the supervision tree of another application. The former allows a single server to look after tables belonging to independent applications, while the latter will let applications to have their own table manager.
A client can request `etsmgr' to take an ETS table under management with the `new_table/3,4' or `add_table/2,3' calls. The client will then use `del_table/1,2' when table management is no longer required.
Internally, an instance of the `etsmgr' server maintains a directory of client pids and ETS table ids. We always use ETS table ids, even for named ETS tables. The directory entries will be indexed by a unique (within the instance) name supplied by the client.
If a client process with a table managed by `etsmgr' crashes/terminates, the table will not be lost. Once the client restarts, it can ask `etsmgr' for the ownership of the table.
If `etsmgr' crashes, and provided that the client has the `trap_exit' flag set, it will receive an `EXIT' message with the process id of `etsmgr'. This should trigger a mechanism within the client to reregister its ETS table(s) with the new instance of `etsmgr' as soon as the server restarts.
If the client does not set the `trap_exit' flag, then it will terminate as soon as `etsmgr' terminates. However, not setting `trap_exit' would be very unusual in an application that cares about resilience!
It is up to the client software on how to wait and/or check for the recovery of `etsmgr'. A set of helper functions, `wait4etsmgr/0,1,2', have been provided for a very simple scenario.
If a client terminates without deleting its ETS table(s), `etsmgr' will inherit the managed client table(s) and keep the data alive until the client restarts, or `etsmgr' itself terminates. Hence, it is important for the client to delete the ETS table(s) prior to normal termination.
The application consists of the following components
| Module | Purpose |
|---|---|
| `etsmgr' | client API module |
| `etsmgr_app' | The main application for the standalone version |
| `etsmgr_srv' | The main `gen_server' managing the ETS tables |
| `etsmgr_sup' | The supervisor managing the `etsmgr_srv' server. |
For standalone mode, all four components are used. It is just a matter of ensuring that the `etsmgr' application is started with or before the client application.
For embedded mode, the main server, `etsmgr_srv', can be put under the supervision of the client application's supervisor. The embedding can be done with or without the `etsmgr_sup' supervisor.
The client module, `etsmgr', is used in both modes to communicate with the table manager.
The main component of `etsmgr' is the gen_server, `etsmgr_srv'. Below are the functions for accessing the services of the manager. There are two variants of each function, one for the unnamed instance, and one for a named instance.
This will create a new ETS table, and the manager will link to the client process. We expect this call to be made when the client has started, or restarted following a crash. In the latter case we would expect the manager to be aware of the entry. On successful completion, the client will be the owner of the ETS table, and `etsmgr_srv' will be the heir.
This is similar to `new_table', except it will not create a new ETS table, but start managing an existing ETS table. We expect this call when a client prefers to create the ETS table itself, or when the manager has crashed and restarted and the client is reestablishing the arrangement. On successful completion, the client will be the owner of the ETS table, and `etsmgr_srv' will be the heir.
This call is used when the client no longer needs a table to be managed, such as prior to termination. It will be up to the client to delete the ETS table.
This is a helper function that can be used by the client to ensure `etsmgr' is up and running, either at start up or following the unexpected termination of `etsmgr'. The functions will block until `etsmgr' is available. The caller can specify a specific `etsmgr' instance and/or the polling interval when checking for the server.
This will return the tables currently under management as a map of maps, or an empty map.

I should start doing more pairs than the required amount. I have noticed the material does seem easier when I work with someone else, even if my pair is not necessarily more knowledgeable on the subject. I should also start making broad or general guidelines for myself. I don't like having everything laid out in front of me step by step, but I do think knowing my general direction is a good thing.
One major thing I have been dealing with is my time restriction. I work 40+ hours a week with over an hour commute each way. I try to work on DBC material every night and then spend almost my entire weekend working on DBC material as well. I have been debating on whether or not I should quit my job early and focus solely on DBC. It is a struggle because I want to succeed and put my all into DBC, but I also need to support myself.The biggest struggle for me so far in my Phase 0 experience has been finding the time to work on all the material. I feel like there have been times when I could have done better on my assignments or dug a little deeper in my research, but I just simply don't have the time right now. This issue is because of my current job and all the time I need to put into that.
For Growth vs. Fixed Learning Style need to work on my on a few areas where I think I partially fall in the fixed mindset. Sometimes I look at a problem as either right or wrong, I fail to see the potential learning that can come out of a wrong answer. Knowledge isn't a destination, it is a journey. I need to realize I will never know everything and no matter how good I get at any one thing I will still need to turn to others for help sometimes.

git-branch(1) Manual Page
NAME
git-branch - List, create, or delete branches
SYNOPSIS
git branch [--color[=<when>] | --no-color] [-r | -a] [--list] [-v [--abbrev=<length> | --no-abbrev]] [--column[=<options>] | --no-column] [(--merged | --no-merged | --contains) [<commit>]] [<pattern>...] git branch [--set-upstream | --track | --no-track] [-l] [-f] <branchname> [<start-point>] git branch (--set-upstream-to=<upstream> | -u <upstream>) [<branchname>] git branch --unset-upstream [<branchname>] git branch (-m | -M) [<oldbranch>] <newbranch> git branch (-d | -D) [-r] <branchname>... git branch --edit-description [<branchname>]
DESCRIPTION
If --list is given, or if there are no non-option arguments, existing branches are listed; the current branch will be highlighted with an asterisk. Option -r causes the remote-tracking branches to be listed, and option -a shows both local and remote branches. If a <pattern> is given, it is used as a shell wildcard to restrict the output to matching branches. If multiple patterns are given, a branch is shown if it matches any of the patterns. Note that when providing a <pattern>, you must use --list; otherwise the command is interpreted as branch creation.
With --contains, shows only the branches that contain the named commit (in other words, the branches whose tip commits are descendants of the named commit). With --merged, only branches merged into the named commit (i.e. the branches whose tip commits are reachable from the named commit) will be listed. With --no-merged only branches not merged into the named commit will be listed. If the <commit> argument is missing it defaults to HEAD (i.e. the tip of the current branch).
The command's second form creates a new branch head named <branchname> which points to the current HEAD, or <start-point> if given.
Note that this will create the new branch, but it will not switch the working tree to it; use "git checkout <newbranch>" to switch to the new branch.
When a local branch is started off a remote-tracking branch, Git sets up the branch (specifically the branch.<name>.remote and branch.<name>.merge configuration entries) so that git pull will appropriately merge from the remote-tracking branch. This behavior may be changed via the global branch.autosetupmerge configuration flag. That setting can be overridden by using the --track and --no-track options, and changed later using git branch --set-upstream-to.
With a -m or -M option, <oldbranch> will be renamed to <newbranch>. If <oldbranch> had a corresponding reflog, it is renamed to match <newbranch>, and a reflog entry is created to remember the branch renaming. If <newbranch> exists, -M must be used to force the rename to happen.
With a -d or -D option, <branchname> will be deleted. You may specify more than one branch for deletion. If the branch currently has a reflog then the reflog will also be deleted.
Use -r together with -d to delete remote-tracking branches. Note, that it only makes sense to delete remote-tracking branches if they no longer exist in the remote repository or if git fetch was configured not to fetch them again. See also the prune subcommand of git-remote(1) for a way to clean up all obsolete remote-tracking branches.
OPTIONS
- -d
- --delete
Delete a branch. The branch must be fully merged in its upstream branch, or in HEAD if no upstream was set with --track or --set-upstream.
- -D
Delete a branch irrespective of its merged status.
- -l
- --create-reflog
Create the branch's reflog. This activates recording of all changes made to the branch ref, enabling use of date based sha1 expressions such as "<branchname>@{yesterday}". Note that in non-bare repositories, reflogs are usually enabled by default by the core.logallrefupdates config option.
- -f
- --force
Reset <branchname> to <startpoint> if <branchname> exists already. Without -f git branch refuses to change an existing branch.
- -m
- --move
Move/rename a branch and the corresponding reflog.
- -M
Move/rename a branch even if the new branch name already exists.
- --color[=<when>]
Color branches to highlight current, local, and remote-tracking branches. The value must be always (the default), never, or auto.
- --no-color
Turn off branch colors, even when the configuration file gives the default to color output. Same as --color=never.
- --column[=<options>]
- --no-column
Display branch listing in columns. See configuration variable column.branch for option syntax.--column and --no-column without options are equivalent to always and never respectively.
This option is only applicable in non-verbose mode.
- -r
- --remotes
List or delete (if used with -d) the remote-tracking branches.
- -a
- --all
List both remote-tracking branches and local branches.
- --list
Activate the list mode. git branch <pattern> would try to create a branch, use git branch --list <pattern> to list matching branches.
- -v
- -vv
- --verbose
When in list mode, show sha1 and commit subject line for each head, along with relationship to upstream branch (if any). If given twice, print the name of the upstream branch, as well (see also git remote show <remote>).
- -q
- --quiet
Be more quiet when creating or deleting a branch, suppressing non-error messages.
- --abbrev=<length>
Alter the sha1's minimum display length in the output listing. The default value is 7 and can be overridden by the core.abbrev config option.
- --no-abbrev
Display the full sha1s in the output listing rather than abbreviating them.
- -t
- --track
When creating a new branch, set up branch.<name>.remote and branch.<name>.merge configuration entries to mark the start-point branch as "upstream" from the new branch. This configuration will tell git to show the relationship between the two branches in git status and git branch -v. Furthermore, it directs git pull without arguments to pull from the upstream when the new branch is checked out.
This behavior is the default when the start point is a remote-tracking branch. Set the branch.autosetupmerge configuration variable to false if you want git checkout and git branch to always behave as if --no-track were given. Set it to always if you want this behavior when the start-point is either a local or remote-tracking branch.
- --no-track
Do not set up "upstream" configuration, even if the branch.autosetupmerge configuration variable is true.
- --set-upstream
If specified branch does not exist yet or if --force has been given, acts exactly like --track. Otherwise sets up configuration like --track would when creating the branch, except that where branch points to is not changed.
- -u <upstream>
- --set-upstream-to=<upstream>
Set up <branchname>s tracking information so <upstream> is considered <branchname>s upstream branch. If no <branchname> is specified, then it defaults to the current branch.
- --unset-upstream
Remove the upstream information for <branchname>. If no branch is specified it defaults to the current branch.
- --edit-description
Open an editor and edit the text to explain what the branch is for, to be used by various other commands (e.g. request-pull).
- --contains [<commit>]
Only list branches which contain the specified commit (HEAD if not specified). Implies --list.
- --merged [<commit>]
Only list branches whose tips are reachable from the specified commit (HEAD if not specified). Implies --list.
- --no-merged [<commit>]
Only list branches whose tips are not reachable from the specified commit (HEAD if not specified). Implies --list.
- <branchname>
The name of the branch to create or delete. The new branch name must pass all checks defined by git-check-ref-format(1). Some of these checks may restrict the characters allowed in a branch name.
- <start-point>
The new branch head will point to this commit. It may be given as a branch name, a commit-id, or a tag. If this option is omitted, the current HEAD will be used instead.
- <oldbranch>
The name of an existing branch to rename.
- <newbranch>
The new name for an existing branch. The same restrictions as for <branchname> apply.
Examples
- Start development from a known tag
This step and the next one could be combined into a single step with "checkout -b my2.6.14 v2.6.14".
- Delete an unneeded branch
$ git clone git://git.kernel.org/.../git.git my.git $ cd my.git $ git branch -d -r origin/todo origin/html origin/man <1> $ git branch -D test <2>
Delete the remote-tracking branches "todo", "html" and "man". The next fetch or pull will create them again unless you configure them not to. See git-fetch(1).
Delete the "test" branch even if the "master" branch (or whichever branch is currently checked out) does not have all commits from the test branch.
Notes
If you are creating a branch that you want to checkout immediately, it is easier to use the git checkout command with its -b option to create a branch and check it out with a single command.
The options --contains, --merged and --no-merged serve three related but different purposes:
--contains <commit> is used to find all branches which will need special attention if <commit> were to be rebased or amended, since those branches contain the specified <commit>.
--merged is used to find all branches which can be safely deleted, since those branches are fully contained by HEAD.
--no-merged is used to find branches which are candidates for merging into HEAD, since those branches are not fully contained by HEAD.

I am a 6th-year graduate student at the University of Texas, where I work with Adam Kraus on a survey searching for binary companions to intermediate-mass stars. I received by B.S. in physics from the Illinois Institute of Technology in 2010.
Outside of research, I enjoy several outdoor activities such as hiking, volleyball, and ultimate frisbee.


Flash
Table of Contents
1 Memory Architecture
Flash memories store information in memory cells made from floating gate transistors. The names of the technologies explain the way the memory cells are organized. In NOR Flash, one end of each memory cell is connected to the source line and the other end directly to a bit line resembling a NOR Gate. In NAND Flash, several memory cells (typically eight cells) are connected in series similar to a NAND gate.
The NOR Flash architecture provides enough address lines to map the entire memory range. This gives the advantage of random access and short read times, which makes it ideal for code execution. Another advantage is 100% known good bits for the life of the part. Disadvantages include larger cell size resulting in a higher cost per bit and slower write and erase speeds. For more details on how NOR Flash can be used in embedded systems, see An Overview of Parallel NOR Flash Memory.
NAND Flash, in contrast, has a much smaller cell size and much higher write and erase speeds compared to NOR Flash. Disadvantages include the slower read speed and an I/O mapped type or indirect interface, which is more complicated and does not allow random access. It is important to note that code execution from NAND Flash is achieved by shadowing the contents to a RAM, which is different than code execution directly from NOR Flash. Another major disadvantage is the presence of bad blocks. NAND Flash typically have 98% good bits when shipped with additional bit failure over the life of the part, thus requiring the need for error correcting code (ECC) functionality within the device.
2 Erase, Read & Write
In both NOR and NAND Flash, the memory is organized into erase blocks. This architecture helps maintain lower cost while maintaining performance. For example, a smaller block size enables faster erase cycles. The downside of smaller blocks, however, is an increase in die area and memory cost. Because of its lower cost per bit, NAND Flash can more cost-effectively support smaller erase blocks compared to NOR Flash. The typical block size available today ranges from 8KB to 32KB for NAND Flash and 64KB to 256KB for NOR Flash.
Erase operations in NAND Flash are straightforward while in NOR Flash, each byte needs to be written with ‘0’ before it can be erased. This makes the erase operation for NOR Flash much slower than for NAND Flash. For example, the S34ML04G2 Cypress NAND Flash requires 3.5ms to erase a 128KB block while the S70GL02GT Cypress NOR Flash requires ~520ms to erase a similar 128KB sector. This is a difference of nearly 150 times.
As mentioned earlier, NOR Flash memory has enough address and data lines to map the entire memory region, similar to how SRAM operates. For example, a 2-Gbit (256MB) NOR Flash with a 16-bit data bus will have 27 address lines, enabling random read access to any memory location. In NAND Flash, memory is accessed using a multiplexed address and data bus. Typical NAND Flash memories use an 8-bit or 16-bit multiplexed address/data bus with additional signals such as Chip Enable, Write Enable, Read Enable, Address Latch Enable, Command Latch Enable, and Ready/Busy. The NAND Flash needs to provide a command (read, write or erase), followed by the address and the data. These additional operations makes the random read for NAND Flash much slower. For example, the S34ML04G2 NAND Flash requires 30µS compared to 120ns for S70GL02GT NOR Flash. Thus the NAND is 250 times slower.
To overcome or to reduce the limitations of slower read speeds, memory is often read as pages in NAND Flash, with each page being a smaller sub-division of erase blocks. The contents of one page is read sequentially with address and command cycles only at the beginning of each read cycle. The sequential access duration for NAND Flash is normally lower than the random access duration in NOR Flash devices. With the random access architecture of NOR Flash, address lines need to be toggled for each read cycle, thereby accumulating the random access for sequential read. As the size of block of data to read increases, the accumulated delay in NOR Flash becomes greater than NAND Flash. Thus, NAND Flash can be faster for sequential reads. However, due to the much higher initial read access duration for NAND Flash, the performance difference is evident only while transferring large data blocks, often for sizes above 1 KB.
In both Flash technologies, data can be written to a block only if the block is empty. The already slow erase operation of NOR Flash makes the write operation even slower. In NAND Flash, similar to read, data is often written or programmed in pages (typically 2KB). For example, a page write alone with S34ML04G2 NAND Flash takes 300µS.
To speed up write operations, modern NOR Flashes also employ buffer programming similar to page writes. The S70GL02GT NOR Flash, for example, supports buffer programming, which enables multibyte programming with similar write timeout for single word. For example, buffer programming for 512 bytes of data can achieve a throughput of 1.14MBps.
3 Power Consumption
NOR Flash memories typically require more current than NAND Flash during initial power on. However, standby current for NOR Flash is much lower than NAND Flash. Instantaneous active power is comparable for both Flash memories. The active power is thus decided by the time duration for which memory is active. NOR Flash holds an advantage when it comes to random reads while NAND Flash consumes comparatively much lower power for erase, write, and sequential read operations.
4 Reliability
The reliability of saved data is an important aspect for any memory device. Flash memories suffer from a phenomenon called bit-flipping, where some bits can get reversed. This phenomenon is more common in NAND Flash than in NOR Flash. NAND Flashes are shipped with bad blocks scattered randomly throughout, due to yield considerations. More memory cells go bad as erase and program cycles continue throughout the life cycle of NAND Flash. Bad block handling is therefore a mandatory capability for NAND Flash. NOR Flash, on the other hand, are shipped with zero bad blocks with very low bad block accumulation during the life span of the memory. Thus, when it comes to the reliability of stored data, NOR Flash has an advantage over NAND Flash.
Another aspect of reliability is data retention, where NOR Flash again holds an advantage. S70GL02GT NOR Flash offers 20 years of data retention for up to 1K Program/Erase Cycles. S34ML04G2 NAND Flash offers a typical data retention of 10 years.
The number of program and erase cycles used to be an important characteristic to consider. This is because NAND Flash memories used to offer 10 times better program and erase cycles compared to NOR Flash. With today’s technological advancements, this is no longer true as both memories are now comparable. For example, both the S70GL02GT NOR and S34ML04G2 NAND support 100,000 program-erase cycles. However, due to the smaller block size used in NAND Flash, a smaller area is erased for each operation. This results in a higher overall life span compared to NOR Flash.
In general, NOR Flash memory makes an excellent choice for applications requiring lower capacity, fast random read access, and higher data reliability, such as is required for code execution. NAND Flash, for its part, is ideal for applications such as data storage where higher memory capacity and faster write and erase operations are required.
5 Addition
5.1 nor flash
- 基本存储单元的并联结构决定了金属导线占用很大的面积，因此NOR FLASH的存储密度较低，无法适用于需要大容量存储的应用场合，即适用于code-storage，不适用于data-storage.
- 基本存储单元的并联结构决定了NOR FLASH具有存储单元可独立寻址且读取效率高的特性，因此适用于code-storage，且程序可以直接在NOR 中运行.
- NOR FLASH写入采用了热电子注入方式，效率较低，因此NOR写入速率较低，不适用于频繁擦除/写入场合.
5.2 nand flash
- 基本存储单元的串联结构减少了金属导线占用的面积，Die的利用率很高，因此NAND FLASH存储密度高，适用于需要大容量存储的应用场合，即适用于data-storage.
- 基本存储单元的串联结构决定了NAND FLASH无法进行位读取，也就无法实现存储单元的独立寻址，因此程序不可以直接在NAND 中运行,因此NAND是以Page为读取单位和写入单位，以Block为擦除单位.
- NAND FLASH写入采用F-N隧道效应方式，效率较高，因此NAND擦除/写入速率很高，适用于频繁擦除/写入场合。同时NAND是以Page为单位进行读取的，因此读取速率也不算低（稍低于NOR.

From: Mr. Maekal Mekha. 17 Copse Hill,Baghdad Iraq My Dear Beloved, Let me start by introducing myself. I am Mr. Maekal Mekha, a Baghdad Citizen, Iraq, a Mechant as an occupation. I have a obscured business suggestion for you. I am a brother to Dr.Gerald Mekha,who worked with Iraq Judicial Commission , Iraq, for over a decade before he died on 20th of March in the year 2007. He died after a brief illness that lasted for two weeks. Before his death he made a vow to use his wealth for the down trodden and the less privileged in the society. When my brother was alive he deposited the sum of £250 Million Pounds (Two Hundred and Fifty Million Pounds) with one United Kingdom Security Company in London. This funds are still with the Security Company for the past 6 years now,the funds are locked in two metallic trunk boxes, deposited with these company, i am in a refugee camp here in Iraq, as a result of the war in Iraq this moment, am sorry am not too fine based on my health,though what disturbs me most is my stroke. Having known my condition and want to make sure i do my father's will, I have decided to donate this fund to an individual or company,that will utilize this money the way I am going to instruct herein. I want an individual or company that will use this to fund and provide succor to poor and indigent persons, orphanages, and widows and for propagating peace in the universe. I understand that blessed is the hand that giveth. I took this decision because I do not have any one that will inherit this money and my staying in the refugee camp, still don't know when i'll be granted the visa permit out of Iraq. I do not want a situation where this money will be used in an ungodly manner, hence the reason for taking this bold decision. I do not need any telephone communication in this regard because of my uneasy access to the facility in the refugee camp here in Iraq. Also because of the presence of social security in the camp, I do not want them to know. With Allah all things are possible. As soon as I receive your reply I shall give you the contact information of the Security Company in London,United Kingdom. I will also issue you a letter of authority that will empower you as the original beneficiary of this fund. I want you to always pray for me. My happiness is that I lived a life worthy of emulation. Whosoever that wants to serve the Almighty Allah must serve him with all his heart and mind and soul and also in truth. Please always be prayerful all through your life. Any delay in your reply will give me room in sourcing for an individual for this same purpose. Please assure me that you will act according to my specification herein. Hoping to hear from you. Thank you and may the Almighty Allah bless you. Kindly send your email message to my mailbox<EMAIL_ADDRESS>, so i can contact you with more information Yours sincerely, Mr. Maekal Mekha
