I often get asked by some other IT guy "why does user XXXXX keep on getting locked out?"
Let me clue you in on something - users (almost) always get locked out for the same reason: They try the wrong password too many times.The reasons for THAT, however, are quite diverse and include:
- People typing in the wrong password
- Computers trying to renew TGTs with an old password (after a different one has been set/reset from somewhere else)
- Some external system (SAP, VMWare SSO...) is using AD as its user store, and is being presented with the wrong credentials from its own client (a web browser, for instance)
I also recently learned that turning on Smart card is required for interactive logon
actually scrambles the user's password as well, so
people being enforced to use smart cards are often locked out without
doing anything other than being logged in (with the now old password).
Finding the root cause is not trivial, but I've created a small
procedure to help the helpdesk / IT team solve such mysteries:
1. Start working immediately after a lockout
Unless you have some fancy enterprise event logging solution (like SCOM's ACS or Symantec's SIM), you better act quick. Events in DCs don't last for long, because they have limited log size and are constantly generating new events. Considering the fact that it's easier to find fresh events anyway, it's usually a good idea to determine when the lockout happens (all the time, every 48 hours...), unlock the account and start looking at logs immediately after it's locked again. Assuming you have a functional PDC, it'll hold the latest user data, so you can check on the user using:
Get-ADUser -Server (Get-ADDomainController -Service PrimaryDC -Discover | Select -exp
hostname) USERNAME -prop LockedOut | select name,LockedOut
2. Search DC security logs for audit logon failures with that user
If you have enterprise event collection, use it.
If you don't (or prefer the hardcore version), you have 3 ways to
filter:
-
Filter every one of your DCs' logs with the following criteria:
- Logged (time): The smallest time range you can afford. I usually take 15 minutes
- Event Logs:
Security
- Event Sources:
Microsoft Windows security auditing.
(this dot is actually there) - Task Category:
Logon, Kerberos Service Ticket Operations, Kerberos Authentication Service
- Keywords:
Audit Failure
And manually search (
Ctrl+F
) for the user name in the resulting event list -
Filter every DC's security log with the following xml criteria:
<QueryList> <Query Id="0" Path="Security"> <Select Path="Security"> Event[ System[ Provider[@Name='Microsoft-Windows-Security-Auditing'] and ( Task = 12544 or Task = 14337 or Task = 14339 ) and (band(Keywords,4503599627370496)) and TimeCreated[timediff(@SystemTime) >= 3600000] ] and EventData[ (Data='USERNAMEHERE') ] ] </Select> </Query> </QueryList>
-
Execute this script, which extracts the event from all of your DCs, and inspect the results:
$timeBack = [timespan]'0:15:0' $userName = 'USERNAME' $msg = Get-ADDomainController -fi * | select -exp hostname | %{ Get-WinEvent -ComputerName $_ -LogName 'Security' -FilterXPath " Event[ System[ Provider[@Name='Microsoft-Windows-Security-Auditing'] and ( Task = 12544 or Task = 14337 or Task = 14339 ) and (band(Keywords,4503599627370496)) and TimeCreated[timediff(@SystemTime) <= $($timeBack.TotalMilliseconds)] ] and EventData[ (Data='$userName') ] ]" } | %{([xml]$_.toXml())} $msg
3. Analyze the failure message
After finding the message, we need to read it to decide why the computer
is locking out the user.
It usually involves locating the following parts of the message:
- Machine / workstation name
- Authentication failure reason: We need to know if this computer is the real culprit (providing wrong passwords) or only a harmless victim (trying to authenticate the account when it's already locked).
These can help: - Logon Type - It helps to know what type of logon was attempted.
For example, it could be physical logon (a good old keyboard-mouse user session) or a service logon (a service with such credentials trying to start). Here is a pretty good list
With these details, we should have a good idea about the computer responsible for the lockout
4. Handle offending computer
Since there are many root causes and many responses, I'll just give a couple of ideas here, categorised by the logon type:
- 2(
Interactive
)
7(Unlock
)
10(RemoteInteractive
)- A user left a session (Console/RDP) running with the wrong password
Either restart the computer, log the user off or unlock the session with fresh credentials - Someone is typing the wrong password (by mistake)
Manually inform the user that his password is incorrect (physically / via helpdesk) - Brute force is being attempted
Security response team?
- A user left a session (Console/RDP) running with the wrong password
- 3(
Network
)
8(NetworkClearText
)
Non-session authentication (basic / network etc.) failing on a domain member
Some server application is being provided the wrong credentials from a client (e.g. IIS using basic authentication, Windows File Server using NTLM…)
Open the domain member's local security log and look for authentication failures to determine the failing computer. Note theCaller process name
field.
Some applications (like SAP) may record their attempts in their own log and not in Windows' event log - 4(
Batch
)
5(Service
)
A service / scheduled task is using the wrong credentials to launch
Find the wrong configuration and fix it. You may use the local computer's security event log - ANY
Failed authentication from a non-domain member (e.g. thin client)
There isn't a lot you can do with these, because they're not domain members. Either handle them (e.g. reset the device) or block them from accessing the DC using some firewall.
Remember: There are other possibilities, these are just some pointers.

Class AdaptiveGrid
A graph like edge-vertex structure with planar spaces connected by vertical edges. The grid doesn't do any intersections when new sections are added, they are stitched only by common vertices. Make sure that regions that are added into the graph are aligned with respect to boundaries and split points.
Examples
var adaptiveGrid = new AdaptiveGrid();
var points = new List<Vector3>()
{
new Vector3(-6, -4),
new Vector3(-2, -4),
new Vector3(3, -4),
new Vector3(1, 4.5),
new Vector3(6, 3),
};
adaptiveGrid.AddFromPolygon(Polygon.Rectangle(15, 10).TransformedPolygon(
new Transform(new Vector3(), new Vector3(10, 0, 10))), points);

Flags to configure the client behavior.
Leaves all files writable on the client; by default, only files opened by 'p4 edit' are writable. If set, files might be clobbered as a result of ignoring the clobber option (see below).
Permits 'p4 sync' to overwrite writable files on the client. noclobber is ignored if allwrite is set.
Compresses data sent between the client and server to speed up slow connections.
Allows only the client owner to use or change the client spec. Prevents the client spec from being deleted or unloaded.
Causes 'p4 sync' and 'p4 submit' to preserve file modification time, as with files with the +m type modifier. (See 'p4 help filetypes'.) With nomodtime, file timestamps are updated by sync and submit operations.
Makes 'p4 sync' attempt to delete a workspace directory when all files in it are removed.


I became interested in mycology (the study of mushrooms)this past year, and experimented with psilocybin mushrooms at various points. However, I got a sudden interest in taking Amanita after reading accounts of Siberian shamans uses of the shrooms. I found a patch growing in some woods near my house, and dried two mushrooms from that patch. I went to work and found a friend there who would be willing to experiment with me. We both ate one mushroom; the initial effects were nothing more than nausea and an energy boost. These, however, passed within thirty minutes. Nothing followed. We were both perplexed, and I became terrified at the prospect of having picked the wrong shrooms (a potentialy fatal mistake; be careful picking your own!). After two hours, I was sitting in the break room reading a magazine when IT happened.
As I tried to focus on the words on the pages of the magazine, my vision became distorted. I realized that I was unable to read - whenever I looked directly at a word, it would disappear! I went out and found my friend, who was also feeling a little trippy at this point. The effects increased, and after an hour, anything I looked at directly would dissolve into microscopic cubes of various colors. Nothing greater than this sensation took place. I came home with a strange body feeling and went to sleep. There were no ill effects, but I wouldn't recommend using the mushroom to anyone. The trip simply isn't that...well...trippy.

Abstract: The nested Chinese restaurant process is extended to design a nonparametric topic-model tree for representation of human choices. Each tree path corresponds to a type of person, and each node (topic) has a corresponding probability vector over items that may be selected. The observed data are assumed to have associated temporal covariates (corresponding to the time at which choices are made), and we wish to impose that with increasing time it is more probable that topics deeper in the tree are utilized. This structure is imposed by developing a new “change point

Pairing with other people to solve some of the challenges has been a life changing experience for me. Up until now I was used to sit alone in front of my computer in my room and code. Not the most pleasurable thing to do specially when you get stuck. Being able to speak up your ideas and listen to possibly better and different approach is the best since sliced bread. It feels amazing to get out of my head and go over even the simplest steps of pseudo-code with my pair and get even a better understanding of the process. Of course there's always that session where for whatever reason it takes a little more work on your part to connect with your partner. That's when I believe that you can make that much of a difference in somebody's life, by making perhaps a little more effort to make it as much as you can, a productive outcome for the both of you.
Reading feedback on me for the first time was very heart-warming. I just couldn't believe that they were referring to me in such a nice way. Even the suggestions about what I could work on were put in such a kind and actionable that it definitely helped me iron out what I needed to in order to become better at working and interacting with other people.
On the other hand, writing feedback that is not only kind, but also actionable, and specific has proven to be the most difficult thing to do yet for me. Going by the ratings mine have been getting I have a lot of work to do. I had to look up the dictionary definition of actionable and specific in order to get a clue on how to write better feedback. I've thought of ways of improving by perhaps taking notes during the session and writing my feedback as soon as possible so that it can be fresh in my head without having to think too hard in remembering the details.
Overall pairing and feedback are the killer-apps of DBC and the other programming bootcamps. They have again demostrated how far ahead of traditional higher education they are in recognizin how something so simple and natural, can take the learning forward by leaps and bounds.


Sometimes a sprite texture contains just a single graphic element but it is often more convenient to combine several related graphics together into a single image. For example, the image could contain component parts of a single character, as with a car whose wheels move independently of the body. Unity makes it easy to extract elements from a composite image by providing a Sprite Editor for the purpose.
NOTE:
Make sure the graphic you want to edit has its Texture Type set to Sprite (2D and UI). For information on importing and setting up sprites, see Sprites.
Sprite textures with multiple elements need the Sprite Mode to be set to Multiple in the Inpsector. (See Fig 2: Texture Import Inspector… below.)
To open the Sprite Editor:
Select the 2D image you want to edit from the Project View (Fig 1: Project View).
Note that you can’t edit a sprite which is in the Scene View.
Click on the Sprite Editor button in the Texture Import Inspector (Fig 2: Texture Import Inspector) and the Sprite Editor displays (Fig 3: Sprite Editor).
Note: You can only see the Sprite Editor button if the Texture Type on the image you have selected is set to Sprite (2D and UI).
Note: Set the Sprite Mode to Multiple in the Texture Import Inspector if your image has several elements.
Along with the composite image, you will see a number of controls in the bar at the top of the window. The slider at the top right controls the zoom, while the color bar button to its left chooses whether you view the image itself or its alpha levels. The right-most slider controls the pixelation (mipmap) of the texure. Moving the slider to the left reduces the resolution of the sprite texture. The most important control is the Slice menu at the top left, which gives you options for separating the elements of the image automatically. Finally, the Apply and Revert buttons allow you to keep or discard any changes you have made.
The most direct way to use the editor is to identify the elements manually. If you click on the image, you will see a rectangular selection area appear with handles in the corners. You can drag the handles or the edges of the rectangle to resize it around a specific element. Having isolated an element, you can add another by dragging a new rectangle in a separate part of the image. You’ll notice that when you have a rectangle selected, a panel appears in the bottom right of the window:
The controls in the panel let you choose a name for the sprite graphic and set the position and size of the rectangle by its coordinates. A border width, for left, top, right and bottom can be specified in pixels. There are also settings for the sprite’s pivot, which Unity uses as the coordinate origin and main “anchor point” of the graphic. You can choose from a number of default rectangle-relative positions (eg, Center, Top Right, etc) or use custom coordinates.
The Trim button next to the Slice menu item will resize the rectangle so that it fits tightly around the edge of the graphic based on transparency.
Note: Borders are only supported for the UI system, not for the 2D SpriteRenderer.
Isolating the sprite rectangles manually works well but in many cases, Unity can save you work by detecting the graphic elements and extracting them for you automatically. If you click on the Slice menu in the control bar, you will see this panel:
With the slicing type set to Automatic, the editor will attempt to guess the boundaries of sprite elements by transparency. You can set a default pivot for each identified sprite. The Method menu lets you choose how to deal with existing selections in the window. The Delete existing option will simply replace whatever is already selected, Smart will attempt to create new rectangles while retaining or adjusting existing ones, and Safe will add new rectangles without changing anything already in place.
Grid by Cell Size or Grid by Cell Count options are also available for the slicing type. This is very useful when the sprites have already been laid out in a regular pattern during creation:
The Pixel Size values determine the height and width of the tiles in pixels. If you chose grid by cell count, Column & Row determines the number of columns and rows used for slicing. You can also use the Offset values to shift the grid position from the top-left of the image and the Padding values to inset the sprite rectangles slightly from the grid. The Pivot can be set with one of nine preset locations or a Custom Pivot location can be set.
Note that after any of the automatic slicing methods has been used, the generated rectangles can still be edited manually. You can let Unity handle the rough definition of the sprite boundaries and pivots and then do any necessary fine tuning yourself.
Open the Sprite Editor for a polygon and you have the option to change its shape, size, and pivot position.
Shape
Enter the number of sides you want the polygon to have in the Sides field and click Change.
Size and Pivot
SIZE: To change the polygon’s size, click on the sprite to display green border lines and the Sprite information box. Click and drag on the green lines to create the border you want, and the values in the Border fields change. (Note that you cannot edit the Border fields directly.)
PIVOT: To change the polygon’s pivot point (that is the axis point the polygon moves around), click on the image to display the Sprite information box. Click on the Pivot drop down menu and select an option. This displays a blue pivot circle on the polygon; its location depends on the pivot option to you have selected. If you want to change it further, select Custom Pivot and click and drag on the blue pivot circle to position it. (Note that you cannot edit the Pivot fields directly.)

Clock
问题描述 :
输入:
The input contains an indefinite number of lines; each line contains four numbers.The first pair of numbers represents an “initial time” the second pair represents a “final time.”
In each such number pair, the first number represents hours, second number represents minutes.
The hours will be in the range 1..12, the minutes in the range 0..59.
No initial time and no final time will be an instant at which the minute hand just passes the hour hand. (In particular, 12 00 will not occur as an initial or final time.)
No initial time will be the same as the corresponding final time.
Between each initial time and corresponding final time, the hour hand will have turned less than one full revolution (360 degrees).
As the hour hand turns from its initial position to its final position, it may or may not sweep past the number 12 on the clock’s dial.
If it does, then either the initial time is an “A.M.” time and the final time a “P.M.” time, or vice versa.
If it does not, then either both times (initial and final) are “A.M.” or both are “P.M.”
Each line of input gives rise to one line of output, containing
the initial and final times, and
the number of times the minute hand passes the hour hand between the initial time and the final time.
Observe all details of formatting, such as upper/lower case letters, punctuation, blank spaces, and the absence of blank lines.
In each time display, the hours and minutes are displayed in fields of width 2, separated by a colon.
The ten’s digit (of hours or minutes) is displayed as a zero if it is zero.

【题意简述】
给定一个开始时间和一个结束时间（12小时进制），求这段时间内时针与分针重叠的次数。
【粗略分析】
先画一下草稿就知道差不多一小时5分钟多一点会重叠一次，
于是我把所有的点算出来 – - ||，然后判断该时间是否在开始与结束时间之内。
是则inc，最后输出结果即可。

The Tolerance
trait contains an implicit conversion that adds
a +-
method to Numeric
types, which, combined with one of the TripleEquals
traits, enables
you to determine whether the numeric value is with a tolerance.
For example, the TripleEquals
trait (and its type-checking siblings TypeCheckedTripleEquals
and
ConversionCheckedTripleEquals
) enable you to write:
result === 10.0 +- 0.5
Here are some examples in the Scala REPL:
scala> import org.scalactic._ import org.scalactic._ scala> import TripleEquals._ import TripleEquals._ scala> import Tolerance._ import Tolerance._ scala> val result = 2.000001 result: Double = 2.000001 scala> result === 2.0 +- .001 res0: Boolean = true scala> result === 2.0 +- .000000001 res1: Boolean = false

If you know me, you know that when I'm passionate about something, I don't stop until I meet my objective. Whether its writing quality code, organizing and promoting large-scale events, or learning how to win at chess, I get results. I try to live every day to the fullest, which means improving myself in any way I can and getting out of my comfort zone. I love learning about the world and the people and places on it, and I hope I can have experiences that can help me do that more.
Worked in an agile team to build a web-app that converts thousands of email messages to texts every day. Our system has over 2,000 active users, and that's growing every day. We use Django to build the web app, AWS to host our service, Selenium Grid to coordinate everything, and Docker to keep everything simple. Check out our website here
Created web app that lets users get their feet wet with cryptocurrency before going out into the real world and losing money. Allows users to buy and sell, and trade coins as well as view portfolio against market trends. While the site is not up, the repo can be found here.
Created device drivers that get read data from the satellite and turn it into something our team can actually use. I followed hardware documentation to write C++ code which was integrated into our GLADOS and LINKSAT systems.

I hope to learn as many languages as possible over the course of my lifetime. I am currently learning French and Dutch. I have taken courses in French for almost 10 years, and its amazing how much better I've gotten over the years. In the Summer of 2018 I had the amazing opportunity to spend two weeks on a french farm near the Rhone river, where I stayed with a host family who didn't speak any english.
I have always been interested in cities and all the awesome things that come with them. Every city, no matter the size, has amazing architecture, food, culture, and history. Although I've been to Amsterdam, Paris, NY, Montreal, and Toronto, Buffalo and Albany still have a special place in my heart. One day I hope to get involved in city government and have a first-hand role in improving the community I live in.

Periodicity¶
The domain above has a periodicity on the side walls and from block 1 to block 2 on the suction side. Plot3D library can find periodic surfaces. Periodic surfaces can only be found by rotation about the x-axis. The user also needs to specify which direction is periodic either i, j, or k. Combinations of outer faces are searched to find the ones that are periodic when rotated about the x-axis and in the “k” direction (default option). Below is an example on how to find periodic surfaces.
In this example we will use the file PahtCascade-ASCII
1from plot3d import write_plot3D, read_plot3D, periodicity, connectivity
2
3blocks = read_plot3D('PahtCascade-ASCII.xyz', binary = False)
4face_matches, outer_faces_formatted = connectivity(blocks)
5periodic_surfaces, outer_faces_to_keep = periodicity(blocks,outer_faces,face_matches,periodic_direction='k',rotation_axis='x',nblades=55)
6# Append periodic surfaces to face_matches
7face_matches.extend(periodic_surfaces)

UPLOAD IMAGE OF "TOMATO" OR "POTATO" CROP LEAF ONLY ACCORDING TO ABOVE TUTORIAL.
DO'S & DON'T ON HOW TO UPLOAD IMAGE
Correct Method
The System works well with single leaf at a time, so try uploading images with one leaf.
In-Correct Method
The System won't predict when more leaves in one image, it is good at predicting one leaf at a time.


Hello World!
By Annie Pennell
August 23, 2015
…Hi! This is my first post of what I hope to be many. Where to start? I guess I should begin with a bit about myself. My background is in photography and, after three years of living in New Orleans and pursuing that, I returned to the Bay Area. At another crossroads with a hazy future in front of me and no map, I decided to make a new path and give this coding thing a shot. I took General Assembly San Francisco’s Web Development Immersive course, a twelve week full stack bootcamp, and I completed several web apps and projects there while learning HTML/CSS/JavaScript, Node.js, Ruby on Rails, and a whole lot more. I followed that up with a Developer in Residence position in GA’S next cohort, which has three weeks left. I am currently in the depths of a job search, eager to begin my life as a real developer!
A side passion of mine has always been crafting of all sorts. I fell in love with cross-stitching the first time a got a little kit with a basic hummingbird pattern. It’s so wonderfully tedious! Off and on for the last few years, I’ve completed projects then forgotten about it. In the last couple months, though, I discovered the world of ironic patterns on Etsy. I bought one and would come home from work and immediately sit down, fire up Netflix, and get right to stitching. I was hooked! After finishing that project, I bought five more patterns and am working through those right now. My friend requested a custom design, so I’m looking into making my own pattern for him.
Well, there you have it. The brief history of my life that has led me to this moment of starting a blog about cross-stitching and coding. Keep coming back for updates on my dev and stitch projects, musings on the strange SF world of tech and start-ups, code and crafting how-to’s, and stories about the terrors of job searching.

CPACS is used in different national and international aircraft design projects. CPACS related software varies from supporting libraries such as TiXI and TiGL to aircraft design software such as VAMPzero. In addition to CPACS based software there are also many tools for which CPACS interfaces have been implemented. A common way for connecting a tool with CPACS is to develop a tool wrapper which translates CPACS data to the tool specific input format, and the tool results from the original output format back into the CPACS format. The advantage of this approach over the using CPACS directly is that you do not need to modify your tool.

If you're heading into the field of application development, web development, and programming, there's a good chance you might have heard the term "SQL injection" by now. Oooooh hacker stuff! So exciting! But what is SQL injection? SQL injection is a technique used by hackers, both whitehat and blackhat, to attack data-driven applications that use any type of SQL database with the goal of stealing data. It occurs by inserting SQL statements into a data field which exploit a security vulnerability in an application's software. One example of this is when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements, or when user input is not strongly typed and unexpectedly executed.
SQL injection (SQLI) is considered one of the top web application vulnerabilities, and is commonly used in coordinated data-heist attacks. There are 5 main types/subclasses of SQL injection. These include:
The most common method of SQL injection is by exploiting data fields where user input is not properly filtered for escape characters, thus allowing SQL statements to be passed. In essence, this allows a user or hacker to access the database through data input fields, potentially allowing this person to copy or wipe the database, or worse, do both.
Luckily, SQL injection can be avoided. Application developers can use a form of input validation to check the user(or hacker)'s input against a set of pre-defined rules for the type of input. Such rules could include constraints on length, or enforcing strong type user input and syntax. In a nutshell, the more "picky" your user input fields are about the type and length of user input allowable, the safer. The sacrifice, however, is flexibility. Another smart thing to do is to ensure that any user input data is not sent to the SQL interpreter as an SQL query. Failing to safeguard against this could allow a hacker to send SQL commands directly through data fields. To prevent this, application devs can use input validation. Lastly, setting user permission limitations to stringent might also prove to be a smart move.


Everybody Wants Some
Superstitions are a holdover from primitive humans finding simple reasons for things they don't understand. Verifiably a complete waste of mental capacity in this day and age. I'm just saying, in a deterministic event, such as hitting a baseball, there actually is a strict relation between cause and effect. Now, superstition, it's bringing a... A probabilistic framework and projecting meaning onto a completely random sequence. See, we can deduce from that, that the lucky helmet was probably not the factor in Coma's ability to get a hit because he was just able to do so without it. The question now will be if this new, random helmet now becomes Coma's lucky helmet.

Tec de Monterrey & Center for Futures
Our design department belongs to the south region of Tec de Monterrey's Architecture, Art & Design School. As such we have much in common as our sister campus in Puebla. However, we have made it a mission to have four specific areas of interest that inform our schools direction in Toluca: Tech Based Products, Speculative Design Practice, Social Inovation & Urbanism.
For that purpose, the Center for Futures was set up, as a coordinating entity for the diverse strategic projects that our school seeks to produce fostering valuable collaborations with an assortment of agents.
Projects Currently Running
This are the projects that are currently running at our design school that I am currently overseeing.
Chiapas
In 2017 the architecture department began a relationship with a series of midwives from the Navil region of los Altos de Chiapas. The project mainly is concerned with building houses where they can devleop their work for the community.
Last winter the design department joined the effort, where we set up a collaboration with multidisciplinary artist Amor Muņoz to create Tec's first winter course. Throughout this course, three main objectives were setup.
On one hand students were part of a highly multidisciplinary experience where they managed to combine ethnographic design research, user centered design practice, electronics, artisanal weaving techniques all in contextualized manner by living and collaborating with the Hernandez family from Navil.
Secondly, the project was a collaboration with a highly regarded artist, Amor Munoz, where she could continue her creative exploration and set up the ground for other future diverse projects.
Finally, students were part of a design research project (which is still ongoing) that is concerned with better ways to create empathy within a ethnographic design process.
Semestre i:EDB
This project seeks to create an intimate interaction between the design, technology and business mindsets in order to create a single tech based product by the end of a single term, in lieu of taking normal courses. That is, the students selected for this experience have 5 months of mentored, tailored education that intersect these three main pillars of viability, attraction and feasibility.
Currently there are three groups developing products by using a methodology that was originally proposed by Federico Hess and Patricia Torres, and has had some interesting revisions where I changed certain elements and introduced speculative design practice in a more promimnent manner in the early phases of the process.
San Mateo Atenco: Local Shoe Industry
The town of San Mateo Atenco is a known shoe production cluster. Although it certainly does not compare to Leon which produces over 76% or Guadalajara as a state with its nearly 11% of shoe production participation at a national level, San Mateo Atenco fosters nearly 800 small and medium producers that range from family run facilities to some more impressive industrial setups. In Toluca itself, at least three large shoe producers are present including Van Vien and Crucero, which are leaders in the manufacturing and commercialization of industrial shoes.
As a design school, through our social innovation optic, we have a mission to foster the growth of the local industry by aligining their production with present and future models in design, manufacturing and commercialization. Specially interesting to us are the opportunities to explore alternative materialities to the ones they have been traditionally associated with, including the implementation of biomaterials and diverse prototyping mechanisms that are to be explored with the school of engineering.
Creative Explorations
In parallel to my main work as Head of Department at Tec, I believe that keeping myself active creatively is a way of being a better academic.
Through a series of new and old explorations in diverse realms, I try to understand the nature of creativity. That is, how it is that we create anything, and what are the rules of what works creatively? A constant exploration is trying to understand aesthetics through a diverse range of mediums and how this different explorations inform each other practice. For the time being my main explorations concern woodworking, furniture design and painting. Previous efforts include creative coding & engineering, filmmaking and musical production.
Although I understand and accept the limitations of this extremely wide assortment of interests, I am comfortable now understanding that as a hobby, this wide range of creative endevours help me improve my practice as a design teacher by empowering students to find their way around andy sort of creative block or obstacle they encounter
Lately I have found a sense of comfort in painting. As a creative catharsis, abstact paintings for me represent a way to express a certain degree of creative frustration; that is I realize that I won't have time in this lifetime to materialize everthing I'd like having so many interest. So through abstract pieces I can make an attempt at channeling that creative energy somehow.
I think of creativity as these formless cloud that hangs beyond the material world, much to my intepretation of the same formless that the Daoism expresses. As creative agents, us humans become channels of that creative cloud, to manifest onto the material world the many diverse ways the formless can be expressed.
Through my abstract pieces I try to capture the formless in its raw form, bypassing the need to create more concrete representations.
Furniture Design, Metal and Woodwork (2017 - Present)
I had the rather stubborn idea of not buying furniture and instead creating everything I own in order to develop a bond with my possesions. This has proven to be complicated given the time constraints but ulimately satisfying.
Using an assortment of woods and metal, I have slowly made my own apartment's furniture (it's still a work in progress honestly) and built last year our store, Muchas Gracias.
Past explorations (2016)
Within my time as an undergrad engineering student, I sought to create multidiscipilinary experiences that often had a slight sense of mexicanity in them. This portfolio is a summary of those times.
Creative Engineering Portfolio, 2017
Clapeyron - Music Project
This music project was a shortlived experiment where the goal was to understand the complexity involved in producing an album without any prior music knowledge, using Ableton Live. I'm one of the two monthly Spotify listeners, and continue to think I should dedicate some time to producing a next piece, but frankly I haven't had the time to do so.

Futurologi
While working developing Steed, I developed futurologi as a forum where to create a tapestry of complex future scenarios based on the opinions of various experts.
In this document there is an example of the kind of experience that was created through this conversations and the organizations involved: Futurologi Portfolio
FACEBOOK PAGE - INSTAGRAM - SITE
The essential energy of the project continues to live now, temporarily through the implementation of the Center for Futures at Tec de Monterrey.
Steed
Steed is a digital product and innovation consultancy that I co-founded in 2015. Although I continue collaborating with Steed, I have taken a step back in order to fullfil my duties at Tec de Monterrey.
Although right now the main service provided is digital consultancy, our main goal is eventually moving onto innovation consultancy. This of course has proven to be rather hard given that the mexican business environment is slowly coming around to understanding the value behind these methodologies.
Steed developed some interesting online and offline projects, including nuevoingenio.mx, which served as a platform of knowledge and exposure for up and coming talent that intersected technology, design & culture and Muchas Gracias Store, an independent fashion design store in Mexico City.

A pure static site just makes everything far more complicated
The idea of lazy image loading is simple - the image wont be loaded until it become visible in the browser (i.e. viewport).
Actually, modern browsers support native lazy loading, simple add loading="lazy"
to the img tag, and, that’s it.

This simple approach works. However, since height of the  element is 0 before load, this will cause content reflow.
To prevent content reflow, we can use “placeholders”. For example, low resolution thumbnails.
Here, I’ll take the dominant color from an image, and generate a tiny pixel thumbnail based on that color (just like Twitter did).
| before load | after load |
|---|---|
Jekyll is a static site generator, which means the whole website will be static. There are no controllers, no databases, only static files.
The only thing we can do is to store required data in the HTML itself and have JavaScript to do the work:

When the img was scrolled into view (using IntersectionObserver), replace the value of src attribute with value of data-src attribute:
const img = document.querySelector('img');
img.setAttribute('src', img.dataset.src); // when scrolled into view
That’s all needed for frontend part.
For “backend”, we can create a Hooks to process images and use gem Miro find dominant colors.
As discussed here, I’ll use URL-encoded SVG as placeholder.
In the hooks GenerateThumbnail.rb:
require 'json'
require 'miro'
require 'image_size'
Jekyll::Hooks.register :site, :after_init do |site| # just after the site initializes
data_file_path = File.join('.', '_data', 'gallery.json')
unless File.exist?(data_file_path)
puts 'Hooks: finding image dominant color..'
gallery_path = File.join('assets', 'gallery')
gallery_data = []
Miro.options[:color_count] = 1 # only take one dominant color
Dir.children(gallery_path).sort.each do |img|
puts "\t> processing image: #{img}"
img_path = File.join('.', gallery_path, img)
img_dimensions = ImageSize.path(img_path).size # get dimensions of image
img_dominant_color = Miro::DominantColors.new(img_path).to_rgb[0] # get dominant color of image
# store data as array of hashes
gallery_data.push({
'name': img,
'basename': img.split('.')[0],
'path': File.join('', gallery_path, img),
'width': img_dimensions[0],
'height': img_dimensions[1],
'dominant_color': img_dominant_color.join(',') # rgb value
})
end
File.open(data_file_path, 'w') { |f| f.write(gallery_data.to_json) } # save as json
end
end
The generated json file will looks like this:
[
{
"name": "DSC01881W.jpg",
"basename": "DSC01881W",
"path": "/assets/gallery/DSC01881W.jpg",

ABSTRACT
Horbenko S.S. Choice the restoring method of details by quality criteria. Visnyk National Transport University. Series «Technical sciences». Scientific and Technical Collection. - Kyiv: National Transport University, 2020. - Issue 1 (46).
The purpose of the article is to analyze the existing methods of surface layer modification and to choose such a method of restoration of parts, which takes into account the quality criteria that affect the operational properties and ensure their required level after the modification process.
The main methods of surface layer modification are considered in the article, the main advantages and disadvantages of technological process that can be applied are analyzed and systematized. In the article quantitative indicators of the main technological parameters of each of the considered methods of restoration of operational properties are considered and presented as a table.
According to the results of the analysis, a method for choosing a rational technological process of restoration was proposed and criteria were formed according to which the most optimal method of surface layer modification would be fulfilled. .
The object of study is the quality criteria and the basic methods for restoring the performance of engine parts that satisfy these criteria.
Using the developed methodology and the data from Table 2, a diagram of the dependence of energy consumption costs, which will be consumed when provided with a layer of certain hardness for a given thickness, was constructed.
Based on the analysis, which included a comparison of the characteristics of surface hardening methods and their evaluation by quality criteria, it was found that the most promising method is ion nitriding and laser thermal hardening.
