Salavat Fidai's microsculptures have been exhibited in London, Singapore, Los Angeles, Sharjah, and Saint Petersburg. Viewers are often provided with magnifying glasses to view the tiny sculptures.
Fidai began sculpting miniature figures out of pencil graphite in 2014. The process is challenging due to the fragile nature of graphite and it is common for the miniature sculptures to fracture after spending many hours on a single piece. Fidai spends between six and twelve hours an average to produce a statuette, while complicated models take between two and three days to create. He uses a craft knife and a stereo microscope for creating the tiny sculptures.

Shoelace is a visual, intuitive Bootstrap 3 grid builder based on the idea that the construction of a responsive grid can be abstracted away from the design of a project.
Shoelace lets you see your grid layout in relation to the media query sizes, and adjust them accordingly. With the live preview, it's easy to see exactly how your grid will behave at any media size.
Sholace is also built to prevent any grid errors or impossible designs. With the "what you think is what you get" grid builder, you don't have to worry about breaking your layout or making a sneaky mistake.
Shoelace is a visual grid builder that lets you draw your grid at any media size, and then adjust it for different media query sizes. The builder is intuitive and knows how to handle the responsible column inheritence and rules.
Shoelace is not a template builder. You don't build your project with shoelace, just your grids and responsive layouts. Or, you can use Shoelace to preview and perfect grid designs as you use them in your projects, without the trial and error of working with your actual code.

How industry-wide effort helps
Surveying problematic for safe autonomous driving situations is a hard problem. Industry addresses this problem with multi-billion dollar investments into fleets of vehicles, safety drivers, engineers and researchers. One of the weaknesses of the industry is that the datasets assembled in this way are expensive, incomplete with no data sharing mechanism available to the participants. Complementing this approach with a public, nonprofit, crowdsourced dataset to map 'unknowns' and 'unknown unknowns' of the hard examples of autonomous driving might create such a mechanism and become a focal point of collaboration in the industry.
Our contributors are individuals and companies who care about autonomous vehicles safety. Please feel free to contribute in any way possible - feedback, tweets, pull requests, donations.

During the initial sprint, I wanted to better understand people’s motivations behind learning another language and explore what patterns of studying behaviors existed. Through interviews, I discovered that people were studying in shorter, more frequent sessions, on the go, and often times spontaneously rather than following a structured study schedule.


About Scientiapy

Watching chapter 1 of Search Inside Yourself, I drew parallels with martial arts. When faced with situations or challenges outside of the comfort zone, by regulating breathing and body posture, you are better equipped to make clearer decisions without the mind been hijacked and loosing control through emotion. Emotional Intelligence is also about payng attention to the moment, not looking at the past or what lies ahead. Developing sensory focus for both intra and inter personal relationships.
Taking two minutes to relax and focus on breathing helped stablise the body and dissipate tension - although a good night's sleep would also help the cause.

We've started remotely monitoring our certificate stores on critical
servers, and wanted the monitoring software to be able to remotely
connect to our servers' personal certificate stores.
I quickly found a script to enumerate all certificates in a specific
store on a remote computer:
function Get-Cert( $computer=$env:computername ){
$ro=[System.Security.Cryptography.X509Certificates.OpenFlags]"ReadOnly"
$lm=[System.Security.Cryptography.X509Certificates.StoreLocation]"LocalMachine"
$store=new-object System.Security.Cryptography.X509Certificates.X509Store("\\$computer\root",$lm)
$store.Open($ro)
$store.Certificates
}
However, as long as the user was not an administrator, it got "access is denied" whenever it tried to open the store ($store.Open
).
Since I don't want the monitoring software to have local admin rights on our servers (BAD habit), I tried troubleshooting the problem.
I found out that the script works locally for every user, so it must be some sort of a remoting issue.
After two hours of troubleshooting I found the problem -
non-administrators, by default, can't execute remote queries against the registry, which is where certificates are stored by default (as told by ProcMon while querying locally).
So after granting the monitoring software remote registry permissions, according to kb314837,
suddenly opening the remote store worked perfectly.
I could rage about it not being documented anywhere, but if everything was properly documented my work will be really boring... Have fun remote-querying!

Apples
No explicit default was set, so per standard functionality
this first tabpanel
will be shown by default.
Here's a link just to test keyboard tabbing.
(it's odd talking about tab
s, and keyboard tabs.)
Bananas
This is an example of a heading being used to populate the
tab
's label, while also not removing heading
from the tabpanel
. This is done by adding
the value "keep" to data-atabs-heading
.

I wrote a post two months ago called the “Steemit Broken Hearts Club.” After that I was able to have @stellabelle on my mspwaves radio show with me. She helped share a distinction of users with me that instantly clicked when I heard it.
There are two types of Steemians
The first type of Steemian is someone who found Steemit on their own after a long journey to get here.
The second type of Steemian is someone who found Steemit because a friend told them to join.
The Earth is broken
I happen to believe a number of controversial theories regarding why the world works the way it does, but the score board doesn’t lie. Just by the public numbers that are known there are eight people in the world have as much wealth as over 3 billion people. The world is constantly at war and under threat of nuclear war seemingly all the time.  The confluence of these things, especially the monetary system induced poverty, creates a scarcity mentality, which is further hyped with round the clock media showing violence and suffering.
A partial recap of my story
My short hand assessment, other than some really lovely people I’ve met or created, is that this whole planet is broken, harmful, and wickedly violent. Somedays I wonder if this is a literal hell.
Now, the consequence of this having to do with Steemit is two fold. I remember in my awakening journey there are two deep spells of depression. The first was after 20-30 years of living under one set of beliefs about how the world works and learning the hard way that the world doesn’t work the way I thought it did. In my case, and from my sense of things of how it works for others, it starts losing a lot of money. I started a business based on some expectations of the world, government, and environment. What should have been a no brainer failed miserably by the very state I was trusting. I lost a lot of money, but also because of that I had to go searching as to how after paying such close attention to the media, officials, and things that were around me that I could have possibly been wrong.
Mark Twain said “It’s easier to fool a man than to convince them they’ve been fooled.” So, I embarked on a multi-year pretty depressing journey to figure out how my smart brain could have possibly been so terribly deceived by this system. So, the first major depression on this journey was really about seeking how could I have been so wrong, and working my way through all that I was taught and paid attention to was just thoroughly false.
So, finding out I was wrong about the world, particularly about the role of this current government as a benevolent force for good in the world was bad and hard. It was pale in comparison to the multi year epic journey trying to figure out how this place actually works. Learning about the Federal Reserve and the system that’s guarenteed to enforce and cause poverty. Learning about the massive harm pharmacuetical companies cause. Forcing myself to realize that 2 planes can’t collapse 3 buildings at free fall speeds directly into their own footprint on the same day. Then working my way back through history to determine other Orwellian historic falsehoods of epic magnitude. And finally coming to accept that the world is quite literally run by horrible immoral banker criminals and that the scoreboard I was seeing was a direct purposeful result of that.
So, there are two major depressions in my life. Each lasted years. Tack into that the death of my mom, challenges caused by drinking for a while, some failed romances, and difficulty with some jobs and you get a picture of some hardship here.

I think basically all category 1 Steemians have something like that
After multiple months of interacting with Steemians of all types in Discord (we’ve got about 5,000 of them in PALnet) I’ve come to the conclusion that we’re a group of mostly broken people doing the best we can to survive, find community, find acceptance, find love, and find purpose. There’s so much emotional, personal, social, and interpersonal dysfunction it’s staggering. We are certainly carving out a digital home, and for many thats at the expense of a terrestrial one.
“Yeah, ok, but what do I do with that @aggroed?”
The plan doesn’t change, the course doesn’t change, the mantra doesn’t change. But we have to learn to integrate it in new ways.
The tack we are sailing is Peace, Abundance, and Liberty.
Those aren’t just nouns they are verbs. They have to be practiced and executed on. The truly hard part is that you don’t just apply those outward. You have to apply them inwards too. You have to make peace with yourself. You have to give yourself freedom to both experience what you have and still love and forgive yourself for it. You have to alllow yourself an abundance. Hopefully it comes financially too, but you have to allow yourself an abundance of joy, of love, of kindness, of gratitude, and of a worthy life.
That often comes with the mantra of deescalation. These things are hard. Not only do you have to try to deescalate conflicts between you and others, but you have to deescalate conflicts internally as well. You have to pull back the language that you are using to describe yourself and others with an intention of self love, outward love, and forgiveness all around.  You have the right of non-consent for the things that aren’t ok, but remember that we’re all flawed, fucked up people here (except maybe you category 2 folks…), and we’re all struggling to figure out a way to live on this planet, with each other, and most difficult of all; with ourselves.
So, here’s my Friday advice
Take a deep breath. Realize that even with your flaws you are a person worthy of love, kindness, and friendship. Try to practice a few acts of everyday kindness and express everyday gratitude.
Chin up. It’s hard, but changing the world is like that. I honor you, I respect you, and I love you for trying. I forgive you when you fail. And for the exceptionally hard I honor me, I respect me, I love me for the work that I do. I forgive me when I fail, and I know I’m doing my best to learn and grow and make this place a better world than the one I found.
Relax, smile, and just in your head pick a random person and think “I hope they have a great day today.”

On reload most browsers will log 'Load', 'Scrolled', 'Appended' and will end up scrolled to the bottom of the yellow div. They attempt to restore scroll state once and stop before the asynchronous function appends the new blue div. Gecko will log 'Load', 'Scrolled', 'Appended', 'Scrolled'. It continues to try to restore the scroll state, making the same intermediate scroll update but also waiting for asynchronous functions to finish before it tries again.
I don't know who is doing it right. Or maybe the spec leaves this up to the user agent.


You are reminded of a civilization that once was, you can walk through the Siq and explore one of the seven wonders of the modern world, the Rose-red city of Petra.

lingvo.core.quant_utils module¶
Utilities for model quantization.
-
class
lingvo.core.quant_utils.
QuantizableLayer
(*args, **kwargs)[source]¶ Bases:
lingvo.core.base_layer.LayerBase
A layer that supports various forms of quantization.
It is always safe to extend QuantizableLayer instead of LayerBase (i.e. at the base of layer inheritance hierarchies) if any layer in the hierarchy may be quantized. Unless if configured/used, all quantization behavior is disabled by default.
Most quantization strategies employed at training time fall into the “fake quantization” category, where we add various constraints in the forward propagation to quantify and simulate the effect of quantization. Within that, we have two major approaches:
- Active clipping: Usually via a schedule, tensors are actively clipped to fall into ranges that we know apriori that the model should be able to deal with.
- Passive tracking and simulation: Passively track the min/max ranges of tensors and insert special ops at training and eval time that constrain to those ranges.
The tensors of interest for both approaches are top-level inputs (or embeddings), outputs of arithmetic operations (add, mul, tanh, etc) and weights. While the actual process of quantizing can be quite complex and involve an end to end view of the system, from a modeling perspective, it can be thought of as providing tags/decorators to arithmetic inputs/outputs. It would be appropriate to think of these as casts which alter the way that the arithmetic operation is tracked and quantize (if Python/Tensorflow were a more strongly typed environment, they would indeed represent types in the type system but given the loose typing, it is just an honor system).
The “decorators” are:
- QWeight: Tags a tensor (typically a var) as a weight quantized type.
- QR* (QRTanh, QRSigmoid, QRSoftmax, etc): Tags a tensor as the result of a fixed activation function with a known output range (the range is implied in the name).
- QRPadding: Tags a tensor as containing a padding value (as we define them as 0..1). While such values are numeric, they generally exist with very different ranges from the rest of the graph and should not be arithmetically combined with tensors that may have a different/variable range.
- QTensor: Tags a tensor as a generic quantized intermediate value. These are also tagged with a layer-unique name. All QTensors with the same name will be considered the same from a numerical range/precision perspective.
Tagging things in this way allows us to, via hyperparameters, associate one or more quantization domains (QDomain) with the layer that will actually perform the necessary tracking and transformations needed at training and inference time to ensure that the layer can operate in low bit inference engines that only have quantized numeric representations. See the SampleQuantizedProjectionLayer in the unit test for an example layer that has had these tags applied.
As a note on terminology, domain/QDomain here refers to a distinct set of quantization rules to apply to a subset of tensors. Most layers will only have one QDomain (default). The concept exists for layers which have been specially created to operate in more than one quantized precision (i.e. an RNN cell that uses 8bit quantization for inputs/outputs and 16bit quantization for internal state arithmetic). Such uses should be rare.
Convenience functions:
The layer adds a number of convenience functions to the layer’s ‘fns’ function library. These mirror similarly named functions in TensorFlow but automatically add the necessary annotations. All such functions take the following named parameters:
- qt: Name of QTensor (setup with TrackQTensor) for dynamic range tracking.
- qmin/qmax/qdomain: Constant min/max range plus optional QDomain name to resolve against. Typically, only qmin/qmax are used.
Functions that have a natural output range will have default values for qmin/qmax so that they just work. Functions that do not have a natural output range must have either qt or qmin/qmax specified manually.
Natural range functions
- qtanh
- qsigmoid
- qsoftmax
Dynamic range functions:
- qadd
- qmultiply
- qmatmul (defers to
py_utils.Matmul
and only accepts rank-2 tensors) - qbatchmatmul (defers to
tf.matmul
directly)
-
TrackQTensor
(*t_names, **kwargs)[source]¶ Creates one or more QTensors for later use.
Any tensor that will later be quantized must be created first, preferably in __init__.
Along with a list of tensor names to create, they can be associated with a ‘domain’. Most layers are simple enough to only have a single quantization domain (QDomain), typically ‘default’. However, additional QDomains can be defined as parameters to control fine grained aspects of quantization.
If no explicit domain is passed, then the domain (‘tensor_’ + t_name) is tried. If that is not defined, then ‘default’.
Parameters: - *t_names – Positional parameters are taken to be QTensor names to create.
- **kwargs – Can contain an explicit ‘domain’. Written this way due to python2 limitations.
-
QTensor
(t_name, t, eval_only=False)[source]¶ Quantizes a general tensor input/output in one step.
t_name must have been previously created via TrackQTensor.
Parameters: - t_name – Previously created QTensor t_name to quantize to.
- t – Tensor to quantize.
- eval_only – Whether to only apply quantization pressure at eval time.
Returns: The tensor, quantized.
-
QTensorMulti
(t_name, *ts, **kwargs)[source]¶ Quantizes multiple tensors simultaneously.
t_name must have been previously created via TrackQTensor.
This is different from multiple calls to QTensor because each of the tensors will contribute to the min/max of the same constraint. Typically used for tensors that are being added together.
Parameters: - t_name – Previously created QTensor t_name to quantize to.
- *ts – Tensor to quantize.
- **kwargs – Additional kwargs as per QTensor.
Returns: Tuple of quantized tensors.
-
QWeight
(w, domain='weight')[source]¶ Quantizes a weight.
Parameters: - w – The weight tensor.
- domain – Custom domain to match (defaults to ‘weight’ or ‘default’).
Returns: The weights quantized.

Note that this returns the “ideal” end range (i.e. -1..1) as opposed to the actual range, which has its upper bound slightly adjusted based on the bit depth of the quantized type. In this sense, this value is a lie, but it is a consistent lie that can be corrected for downstream by the inference engine once it has inferred the actual quantized types being used.
Note that this also assumes the default start/end caps. Some internal parts may use altered caps or bit depths.
Returns: Tuple of (min, max) for the final range.
-
GetQuantizedEndRange
()[source]¶ Gets the quantized ending range.
Unlike GetEndRange(), this takes quantization effects into account. The default implementation just returns self.GetEndRange(). Subclasses can include additional keyword arguments, tightly coupling them to callers of specific types.
Returns: Tuple of (min, max) for the final range.
-
ApplyConstantClip
(x, min_value, max_value)[source]¶ Applies a constant clip with the clipping op for the implementation.
This is a special case which allows applying a custom clipping range to constants that are not used arithmetically. This exists to support padding.
Parameters: - x – Tensor to clip.
- min_value – Minimum value.
- max_value – Maximum value.
Returns: Tensor clipped.
-
GetState
(theta)[source]¶ Gets a state tensor that can be used to calculate clipping.
The state will be a float32 tensor that is safe to pass to TF functions.
Parameters: theta – Layer theta. Returns: An opaque tensor to be passed to ApplyClippingWithState().
