Graphite Mold for Casting Brass Pipe Fitting Casting
Objective:
The goal of this small project was to design and machine a graphite mold for casting brass into a pipe fitting. The specific fitting type is a male to barbed fitting.
Limitations:
There were few limitations due to the available resources and tools.
- Graphite cylinder Size: The mold had to be cut from a graphite cylinder of diameter 4.5 inches and height of 6 inches.
- The mold had to be machinable only using lathe and hand tools.
- The mold had to be reusable.
The Fitting
The first step I took was to create a solidwork model of the pipe fitting that I intended to make a mold for.
The template model for the pipe fitting did not have to be this detailed, but I placed the details for practice.
These steps were used to simplify the template model and to build the mold:
- The threads and the barbs were filled more material to create a smooth surface.
- The scale tool in the SolidWorks Mold Tools set was used to compensate the volume shrinkage of the typical brass metal during solidification and cooling.
- The Draft Analysis and draft tools were used to give a 3 degree draft to the model in the directions where the fitting would be pulled away from mold.
- The Parting Line tool was used to indicate at which plane, the mold will be separated in two parts
- The Shut-Off Surfaces tool was used to specify which "surrounded volume" would be part of which mold-part
- The parting Surfaces tool was used to clearly indicate the separation point between the two mold parts
- Finally, the Tooliing Split tool was used to create the two parts of the mold.
I repeated the above steps two model 4 different designs for the mold
Design 1
Bottom
Top
Resulting Cast
Pros:
- Requires only 1 graphite block to build
- Easiest to fabricate
- Top part is optional
Cons:
- The core need to be drilled out, resulting in a large brass waste.
- The wrench grip area needs to be post machined
Design 2
Bottom
Top
Resulting Cast
Pros:
- Easy to fabricate
- Less wasted brass
Cons:
- Requires two graphite cylinders to fabricate due to the extending cone of the top mold part
- The wrench grip area needs to be post machined
Design 3
Bottom
Top
Resulting Cast
Pros:
- Requires only 1 graphite block
- Wrench grip area is preformed
- Only trimming and threading required
Cons:
- Hardest to fabricate. Requires pin-point cutting tool and inner tapering in forward and reverse directions.
- The molten brass entrance paths are only 0.17 inches wide in diameter
- The wrench grip area may not actually be filled depending on the fluidity of the molten brass.
Design 4
Resulting Cast
Pros:
- Requires only 1 graphite block
- Has only 1 part.
- Less brass is wasted due preformed core
- Easiest to fabricate
Cons:
- Requires the most post machining work
In the end, the design 4 was chosen due to its simple design and fabrication method.
Fabricating the Mold
The main tool used to fabricate the mold was the lathe. We made our custom cutting tool out of high speed steel. This cutting tool had length equal to the pipe fitting that we desired to cast, and had double cutting edges (each tapered at approximately 3 degrees).
This allowed us to fabricate both inner and outer tapering surfaces in a single lathe process.
We were successful in fabricating the mold giving slighly more leeway in the outer and inner diameter of the pipe fitting.
Casting the brass
We used an electric meltring furnace to heat the scrap brass and copper pennies into molten brass. The Copper zinc alloy melted at about 1150 degrees celsius. The molten brass then poured into the graphite mold that was at room temperature.
Initial Problems:
Unfortunately, there were few unforseen problems:
- The 3 degree taper in the inner cone of the mold was insufficient for the cast to be removed from the mold.
As the molten brass shrunk during solidification and cooling, the cast created a tight grip on to the cone shaped extrusion of the mold. This grip was so tight that the cast could not be removed without breaking the cone-extrusion itself.
- The surface of the cast was uneven, and a lot of bumps and dips were present.
The mold's inner surface was not smooth as desired due to the undesired flexing of our cutting tool.
Solutions to Initial Problems
The first problem was addressed by removing the cone-shaped extrusion and replacing with a destructable "cone core" made out of resusable "green sand" or casting sand.
We cut a circular slot at the bottom of the mold where the cone-shaped casting sand structure can be fitted for the casting.
The images below shows the graphite mold and the cone-shaped extrusion core made from casting sand:
The second problem was addressed by using a standard metal cutting tool, and the taper attachment on our lathe to refinish the inner surfaces of the mold.
Below images show the resulting cast:
The casting sand core can be easily broken and removed.
Post machining:
The resulting brass cast was then machined with the lathe to smooth out the surfaces and to create the threading and the barbs.

Cooling and power best practices for distributed computing projects
1. Choose a quality power supply- Power supply with higher 80 plus rating will provide lowest cost of operation, as well as produce less heat
- From highest(most efficient) to lowest(least efficient): 80+ Titanium, 80+ Platinum, 80+ Gold, 80+ Silver, 80+ Bronze, and 80+
- Reputable brands such as Corsair, Antec, BeQuiet or Seasonic have proven to operate at high loads for long periods of time
- Avoid EPS splitters to power motherboards
- Avoid using PCI-E power splitters
- If making splices always solder
- Male PCI-E ends can be re-pinned to EPS.
- Use high quality powered riser cables.
- Use cord included with PSU
- Ensure any surge protector has a least 12ga wire when running multiple machines from one surge strip
- Do not ever plug a surge bar into another surge bar
- Avoid any light gauge cables, especially on high-draw applications
- Avoid the use of extension cords
- Always ensure you have air flow over and under motherboard. Position these fans to the edge of the board. You want a good flow over top and bottom of board.
- Ensure ambient air movement around GPUs
- When possible, apply heat sinks to VRMs. Cool with fans
- If not using a case (naked) do use stand offs to suspend board off of any broad surfaces
- Use larger coolers to dissipate more heat
- PWM fans can ramp up/down based on heat, minimum duty cycles can be specified on some motherboards.
- Using software (Windows) to manual control or monitor GPU temps or adjust GPU fan, such as ATI’s Catalyst control center, Nvidia control panel, Trixx(ATI), MSI Afterburner (ATI & Nvidia), or EVGA Precision-X (Nvidia)
- Monitor ambient temps using a thermometer (IR thermometers can be used to monitor CPU sockets, boards, chips, and other devices)
- Do be mindful of breaker or fusing limits.
- It is recommended to use dedicated breakers for high draw applications (multiple 4p or multi GPU machines)
- For "farm" DC projects, consult an electrician for your application. We do not advocate DIY electricians.
- A Kill A Watt can be used to measure the draw in watts or amps to avoid overloading circuits.

P!nk and Chr!s Stapleton Perform ‘Love Me Anyway’ at the CMAs
by Rebecca Alter
Could you?
Could you?
Could you …
… Believe Pink would give anything other than an emotional awards-show performance?
Okay, so part of us wanted Pink to dramatically throw off her poncho to reveal silks that would hoist her up into a beautiful country-tinged aerial number during her performance of her ballad “Love Me Anyway” at last night’s CMA Awards. Of course, we got the next best thing: sweet, sweet harmonies with country-music singer Chris Stapleton. Pink and Stapleton performed for the audience with a pianist, backing guitar, and string quartet, because there’s no genre she can’t make her own. It’s pleasant and lovely to watch Stapleton and Pink post-apocalyptically harmonizing through the smoky-hazy orange lights and fog effect, could you love me anyway / like it’s the end of the world?
So sure, Kacey Musgraves. You might have won the CMA Award for Music Video of the Year for “Rainbow.” But never forget who the true queen of awards-show vocals is. Pink invented rainbows.

Java JDBC TutorialJDBC stands for Java Database Connectivity. JDBC is a Java API to connect and execute the query with the database. It is a part of JavaSE (Java Standard Edition). JDBC API uses JDBC drivers to connect with the database. There are four types of JDBC drivers:
We have discussed the above four drivers in the next chapter. We can use JDBC API to access tabular data stored in any relational database. By the help of JDBC API, we can save, update, delete and fetch data from the database. It is like Open Database Connectivity (ODBC) provided by Microsoft. The current version of JDBC is 4.3. It is the stable release since 21st September, 2017. It is based on the X/Open SQL Call Level Interface. The java.sql package contains classes and interfaces for JDBC API. A list of popular interfaces of JDBC API are given below:
A list of popular classes of JDBC API are given below:
Why Should We Use JDBCBefore JDBC, ODBC API was the database API to connect and execute the query with the database. But, ODBC API uses ODBC driver which is written in C language (i.e. platform dependent and unsecured). That is why Java has defined its own API (JDBC API) that uses JDBC drivers (written in Java language). We can use JDBC API to handle database using Java program and can perform the following activities:
What is APIAPI (Application programming interface) is a document that contains a description of all the features of a product or software. It represents classes and interfaces that software programs can follow to communicate with each other.

Starting with version 1.5, you can use the connection/result handle as a Tcl command. What this means is that when a handle for a connection or result is generated, a corresponding Tcl command is also generate. For example, you can do the following:
set conn [pg::connect template1 -host $host -port $port] set res [$conn exec "SELECT datname FROM pg_database ORDER BY datname;"] set datnames [$res -list] $res -clear rename $conn {} ;# or $conn disconnect
Note that deleting the command (rename $conn {}), has the same effect as pg::result $res -clear (if it is a result handle), and pg::disconnect (if it is a connection handle). Also, if that command gets overloaded with a proc definition, then that has the same effect as deleting the command.

Polls suggest that the UK general election on May 7 will result in a hung parliament. A coalition, or a minority government backed by a “confidence and supply” deal with other parties, is likely to come to power. This graphic shows the scenarios possible based on the final pre-election projection from ElectionForecast.co.uk. Compare this to the exit poll, the outgoing parliament or create your own distribution of seats by adjusting the sliders below.
Although 326 seats is a majority in the 650-seat House of Commons, Sinn Féin MPs do not take their seats and the Speaker and Deputy Speakers do not vote, so the number of seats needed to win a vote will be lower, probably 323.

XML To Pandas
Table of Contents
Beginning
I went to the Social Security website to change my password (I had forgotten it so they mailed a temporary one to me) and noticed that they have your yearly reported earnings both as a PDF and as a data download. Unfortunately the data is given as an XML file instead of a CSV (it has more than just the earnings data, so it would have to be a series of CSVs instead of one file) so these are my notes on converting it to a pandas DataFrame using BeautifulSoup.
Imports
To actually do the conversion you only need BeautifulSoup and pandas, all the rest of the stuff comes into play because I'm making a post.
# python
from argparse import Namespace
from functools import partial
from pathlib import Path
import os
import random
# from pypi
from bs4 import BeautifulSoup
from dotenv import load_dotenv
import hvplot.pandas
import pandas
# my stuff
from graeae import EmbedHoloviews
Set Up
The Dotenv
I'm using a .env
file to point to the location of the file so this call will load it.
load_dotenv(override=True)
The Plotting
This is just a central place to set up some constants so I don't have to re-type them or hunt around for them if I want to change things.
SLUG = "xml-to-pandas"
Embed = partial(EmbedHoloviews,
create_folder=True,
folder_path=f"files/posts/{SLUG}")
Plot = Namespace(
width=990,
height=780,
tan="#ddb377",
blue="#4687b7",
red="#ce7b6d",
font_scale=2,
)
The Random Seed
I decided since I'm talking about social security stuff I'd make at least some attempt at obfuscating things so I'm adding a random offset to the years.
OFFSET = random.randint(10, 20)
Middle
The XML
Loading It
First, I'll load the XML into BeautifulSoup.
path = Path(os.environ["SOCIAL_SECURITY"]).expanduser()
assert path.is_file()
with path.open() as reader:
xml = BeautifulSoup(reader.read(), "xml")
Note that you have to pass in the "xml"
argument - BeautifulSoup is primarily an HTML parser so it assumes an HTML document by default. Normally I'd do some exploring at this point, but I didn't find it such an easy thing to do (I don't work with XML data generally) and found that it was easier to look at it with less and figure out what I needed.
The Earnings
The data I wanted is in a set of tags that look like this:
<osss:Earnings endYear="1998" startYear="1998">
<osss:FicaEarnings>526</osss:FicaEarnings>
<osss:MedicareEarnings>526</osss:MedicareEarnings>
</osss:Earnings>
This set represents what was collected in 1998 - $526 for Social Security and Medicare (FICA stands for Federal Insurance Contributions Act and is the name of the tax that funds Social Security). Yes, I only made $526 in 1998 because I was a teenager working a part-time job taking store inventories - still, I can't believe how little I got paid…
Anyway, so the first thing to do is to grab all the nodes representing earning.
earnings = xml.find_all("Earnings")
print(len(earnings))
print(earnings[0])
34 <osss:Earnings endYear="1998" startYear="1998"> <osss:FicaEarnings>526</osss:FicaEarnings> <osss:MedicareEarnings>526</osss:MedicareEarnings> </osss:Earnings>
The Years
Now that we have the earnings, we can see about getting the years. Although they have endYear
and startYear
they're always the same so I'll use startYear
. I'm adding the OFFSET
here just to obfuscate what years I'm looking at.
for year in earnings[:5]:
print(int(year.get("startYear")) + OFFSET)
1998 1999 2000 2001 2002
Collected
Next I'll see about grabbing the amounts collected for each year. The FICA and Medicare amounts are always the same so I'll just use the FICA amount.
for year in earnings[:5]:
print(year.find("FicaEarnings").string)
526 1123 1546 0 0
That looks right. It drops to 0 because I went to college and started working on campus and since I went to a state university they didn't collect FICA.
To a DataFrame
Anyway, that's basically all you need to get it going.
data = pandas.DataFrame.from_dict(
dict(
year = [int(year.get("startYear")) for year in earnings],
amount = [int(year.find("FicaEarnings").string) for year in earnings]
)
)
data["offset"] = data.year + OFFSET
print(data.head(5)[["offset", "amount"]])
offset amount 0 1998 526 1 1999 1123 2 2000 1546 3 2001 0 4 2002 0

data.to_csv(csv, index=False)
End
I usually like to put in a little plotting so I'm going to plot the amount over time. Since I already shared my first five years I'm going to start after that and obscure the numbers a little.
Time Series
First I'll add the offset year back in, then I'm going to scale it.
data["year"] = data.year + OFFSET
to_plot = data.iloc[5:]
MAX = to_plot.amount.max()
to_plot.loc[:, "amount"] = to_plot.amount/MAX
plot = to_plot.hvplot(x="year", y="amount").opts(
title="Income Over Time",
width=Plot.width, height=Plot.height,
fontscale=Plot.font_scale,
xaxis="bare",
color=Plot.blue,
)
outcome = Embed(plot=plot, file_name="income_over_time")()
print(outcome)
Well, there you go. Since I'm adding a random offset to the years I removed the x-axis labels, but the plot starts out with me still working for the State, so there's no reported income, then there's an uptick when I took a retail job, then a drop again when I went back to school for a little while to look into getting a design degree, then there's another uptick when I gave up on the design degree and went to work as a clerk for a real estate office, then the next drop comes when I went back to get a Computer Science degree and the rising after that shows the difference between working retail/clerical versus being a computer programmer, with the two plateaus representing the two companies I've worked for.

I went back to the gym this week. I did it to stop myself from making anymore excuses. I have feeling super lackluster in terms of drive lately and so to reignite myself with a sense of purpose, I have decided to start exercising again. It doesn’t matter that I am injured, simply work around the problem. No excuses.

There were a couple of reasons that led to this decision: practice ABC (always be coding) work on more projects There’s probably more, but those are the main ones. I had gotten into programming a bit late, if I wanted to keep up I needed to be constantly improving my skills.

Humble beginnings I first learned to type and then learned to program. I remember when I was still in High School a couple years back (wow, more than 5!) whenever I had the need to type papers or anything on the computer, I would type.. like a noob. I did a bit better than hunt and peck as I used more than just my index fingers to type but I was still heavily inefficient....

Tempter of the Bone again
问题描述 :
Ignatius found some bones in an ancient maze, which fascinated him a lot. However, when he picked them up, the maze began to shake, and Ignatius could feel the ground sinking. He realized that the bone was a trap, and he tried desperately to get out of this maze.
Suddenly, Ignatius heard a very very cool voice, and he recognize that it comes from Beelzebub feng5166:“I know that you like bone, and even I know your nick name is wishingbone. Today, I give you a chance to survive: there are N kinds of bones here and the number of each kind bone is enough, their weights are Wi pounds (1<=i<=N), your bag has a volume of M pounds, and I also know that you will spend 3 seconds time when you pick up any one bone. Today, you must fill up your bag as quick as you can, otherwise, the maze is your place of the death!”.
Oh, my god! Can the poor Ignatius survive? Please help him!
Note: You are guarantied that solution always exist for every test case.

题目意思：把包放满至少需要几个东西，每个东西数量足够。
第一感觉就是背包问题。由于容量最高10亿，把这个作为背包就不现实了，但发现物品种类最多9个，而且重量上限只有100，于是考虑从这里入手。但不知怎么回事，草稿打着打着灵感一来用了递归。搞一个函数ans(x,y);返回x的容量从第y件物品开始放最少需要几件，物品先递减排序。
需要得到的结果自然是ans(背包容量,0);
函数里面：
如果这件物品能放满直接返回x除以第y件物品的价值
如果不能且接下去没有物品了返回-1
走到这一步说明不能放满，还有余数，且接下去还有更小的物品，那就得到一个ans(x%value[y],y+1)。
但这样不一定能得到答案啊，比如说12容量的背包，物品价值有5、3，先放了5，还余2，那3就放不了了，但答案就是3的价值放4次啊。
那怎么办呢？本来只考虑5放2次的情况，那我把5放0~2次的情况都考虑遍，取最小值就好了。
最后还有个问题，(10亿-1)的背包里放价值5可放(2亿-1)次，都考虑过来明显不行。
这个就要看接下来那个数了，比如说接下来的数是3，我只要考虑5最多少放(3-1)次即可，为什么呢？当时感觉就这样=。=，说不清楚，就是这里原以为会WA，结果居然AC了。
感觉跟余数什么的有关，求解释！！
#include<iostream> int N,M,W[10]; int cmp(const void *a,const void *b){ return *(int *)b-*(int *)a; } int f_min(int x,int y){ if(x==-1)return y; return x<y?x:y; } void get_W(){ int i; for(i=0;i<N;i++) scanf("%d",&W[i]); qsort(W,N,sizeof(int),cmp); } int ans(int bag,int s){ int w=W[s],up; if(bag%w==0)return bag/w; if(s==N-1)return -1; up=bag/w; int lim=f_min(up,W[s+1]-1),i,min=-1,temp; for(i=0;i<=lim;i++){ temp=ans(bag%w+i*w,s+1); if(temp==-1)continue; min=f_min(min,up-i+temp); } return min; } int main(){ while(scanf("%d%d",&N,&M)&&(N||M)){ get_W(); printf("%d/n",3*ans(M,0)); } return 0; }

不错，值得借鉴
什么破题，题意好难懂啊
这是什么鬼，怎么多头文件
写的好····· Pollard Rh
这是什么编译器啊，不通过
有点意思
if(j){
int ans=a ;
for(int x=j-1;x>=0;x–){
if(!a ) break;
ans=min(ans,a );
sum+=ans;
}
}
求解释，，dp的思路是什么呢？
跟书上的解法不一样，不知道哪个效率要高些
为什么不直接用STL排序呢？
其实就是DFS搜索，数据量较小，穷举了所有情况
博主的C++功底真是好
int L[m+1][n+1];这样定义出错，这个在gcc上可以编译通过 在VS上不行 应该改为new 或者vector
51行错了，改为：void Union(struct subset subsets[], int x, int y)
题目需要求解的是最小值，而且没有考虑可能存在环

I am interested in seeing if there is a correlation between life and financial satisfaction and what peoples think is important in life. My guess would be that the more money and better health, the less important family is and maybe leisure time is more important.
Started with selecting the wave. I took 1995-1998, 1999-2004, 2005-2009 and 2010-2014.
Next I choose all the possible countries. A lot of clicking!
Here I selected the variables I wanted to use.
This table shows important in life crossed with financial satisfaction.
It apperars that for people that are completely dissatisfied with their financial situation the family is very important.
It apperars that for people that are completely dissatisfied with their financial situation the leisure time is not as important as the family, which would confirm my theory.


ROSEWOOD A film review by Mark R. Leeper Copyright 1997 Mark R. Leeper
Capsule: This is a powerful historical account with an epic feel made on a subject that has never been adequately covered by film. This story of a race massacre in 1923 Florida is intelligent and exciting, a difficult mix. Stylistically similar to MATEWAN and perhaps even better, John Singleton's film will probably be among the best of the year. Rating: +3 (-4 to +4)
I suppose for me the low point of ROSEWOOD was when at the end of the opening credit sequence it says the film is based on a true story and then immediately sets the date as Thursday, December 31, 1922. It damages the credibility of a film when a screenwriter seemingly could not be bothered to pick up a World Almanac to check a day of the week. (A quick calculation told me it was a Sunday.) Indeed, the story that is told is admitted to be still very controversial in its facts and a filmmaker generally has no good way of distinguishing, scene-by-scene, fact from conjecture. This is one version of the events and one that still may be closer to the truth than the Florida state's official version. ROSEWOOD gives us a harrowing depiction of the race massacre as it has not been shown on film before and one that some people will be reluctant to believe could happen in this country.
In the early 1920s the town of Rosewood is a prosperous black community in what should have been a pleasant natural setting in Florida. However, there are long simmering resentments by local whites, many of whom were not so successful but who felt a natural superiority because of their skin color. The film opens the day before the historic events to give a view of life in and around Rosewood. Whites with some money use the blacks for menial tasks and generally seem more interested in fooling around than in actual work, most of which seems to be being done by blacks. We focus particularly on two men. The first is John Wright (played by Jon Voight) who runs a grocery and general store in Rosewood. He deals with blacks every day but still thinks there is something not quite right about blacks being allowed to join the army and kill white Germans.  Today he would be classed as a bigot, but for 1922 he almost passes as a reasonable and enlightened man. We see riding into town a tall, dark, handsome stranger, in the tradition of Westerns, who is just visiting the area looking for a place to settle down. He is Mann (Ving Rhames), an erudite army veteran. One more or less expects his dramatic arrival to be part of the chain of events that starts the riot that is to come, but that story is told fairly accurately and he and Wright are purely fictional characters created for the purpose of the story. The actual historic incident begins New Year's Day when white Fannie Taylor (Catherine Kellner) is beaten by her white lover. In order avoid the wrath of her jealous husband and to explain the bruises to the community she claims that a black man came to her door and started beating her. The person who really beat her was seen by her hired help, Sarah Carrier (Esther Rolle), but Sarah is afraid to speak out and risk vengeance on herself. "'Nigger' is another word for guilty," she laments. Fannie carefully added to her story that she was not raped, but the local low-class white population, chaffing at the mere presence, not to mention prosperity, of some of the blacks, forms a lynch mob to find victims. And so the events start rolling.
Chief among the mob is Duke (Bruce McGill), local white trash who in the course of the film glories over his good work of killing blacks and tries carefully to pass on to his son the finer points of how to tie a noose and the best ways to lynch a black in some of the most chilling scenes of the film. Still Gregory Poirier's script, which may at times be overstated, shies away from showing the events in their full grimness. At the height of the killing the script brings in Mann, a larger than life hero to protect the young. Sadly his heroics are just a wishful fantasy of the script, though some exciting action sequences toward the end of the film really are based on fact. One of the strengths of the script is the ambiguity of some of the characters. Is grocer Wright a bigot who will side with the lynch mob or will he side with the blacks that he has known. How do we place Mrs. Wright the quiet and ineffectual churchwoman. Is Mann ultimately a coward or a hero? Is Sheriff Walker, who walks with the mob, restraining the killers or supporting them?
It is odd that in a film by and about black people the most interesting character is white, but Jon , ambiguous tradesman really remains just about the best thing in a very good film. In stark contrast to his muted character, Ving Rhames is magnetic and powerful, but somehow seems to have stepped into the wrong film. He is the one flaw in the otherwise very good period feel of this film. This is a man who would have fit much better into a brash Western--in fact his character seems as if he could have been based on the Danny Glover part in SILVERADO. There must have been some sort need felt to have a black hero. In fact historically the real heroes, and we do see a little of this in the film, are the white people who risked bringing the wrath of the mob onto themselves to give shelter to blacks.
At 140 minutes, this film qualifies as a genuine film epic, and one of the few we have seen in a while. It has the feel, however, of a film that used a low-budget wisely rather than being a big-budget film. In that regard it is very similar to MATEWAN. I have not cared for what I have seen from director John Singleton to this point, including the highly-touted BOYZ N THE HOOD, but ROSEWOOD is quite another matter. This is a film that deserves multiple viewings. I give it a +3 on the -4 to +4 scale.
The following is an account of the Rosewood Incident as described in a Florida State document submitted on March 24, 1994 in investigation of the incident.
SPECIAL MASTER'S FINAL REPORT The Honorable Bo Johnson Speaker of the House of Representatives Suite 420, The Capitol Tallahassee, Florida 32399-1300
RE: HB 591 by Representatives De Grandy and Lawson Claim of Arnett Goins, Minnie Lee Langley, et al. v. State of Florida
FINDINGS OF FACT: THIS IS AN EQUITABLE CLAIM SEEKING $7.2 MILLION FOR DAMAGES RESULTING FROM THE 1923 DESTRUCTION OF ROSEWOOD, FLORIDA.
[Text deleted]
Upon review of the record presented, and consideration of the sworn testimony, the following description of the events which occurred in Rosewood in 1923 emerges. In January of 1923 Rosewood was a small, mostly African-American community of approximately 120 residents located on the Seaboard Air Line Railroad in western Levy County, nine miles east of Cedar Key. Today the site of Rosewood is marked on State Road 24. At one time the community had a timber mill, a post office, several stores, a depot and hotel; however, by 1923 the cedar wood had been harvested, and the sawmill operations moved to Sumner, a somewhat larger community, three miles west of Rosewood. The black residents remaining at Rosewood earned a living by working at the Cummer sawmill in Sumner, trapping and hunting, and vegetable farming. In addition, several of the black women of Rosewood worked in domestic capacities for the white residents of Sumner. The main store of Rosewood was owned and operated by a white man named John Wright. In 1923 the black community of Rosewood consisted of approximately twenty families, many of whom were closely related through marriages. Some of the black families owned their homes as well as other property in the area. The community had a one-room school, at least two churches, and a masonic lodge. The railroad depot remained, but it does not appear that there was a regularly scheduled stop at Rosewood at that time. There was no history of racial tension at Rosewood, and the record indicates that prior to 1923 the black and white communities had a generally amiable relationship.
On Monday, January 1, 1923, in Sumner, Florida, Mrs. Frances Taylor, a twenty-two year old white housewife, alleged that a black man had entered her home and assaulted her. Mrs. Taylor, who was visibly bruised, told her neighbors that while her husband James Taylor was at work at the sawmill, an unidentified black man had assaulted and robbed her. The specific nature of the assault is not apparent from the record; however, the white community believed there had been a sexual assault, although it does not appear that Mrs. Taylor was ever examined by a physician. After repeating her allegations, Mrs. Taylor then collapsed and was taken to a neighbor's home.
A contradictory account of this event circulated in the black community. According to Mrs. Sarah Carrier, a black woman from Rosewood who did laundry for Mrs. Taylor, and Mrs. Carrier's granddaughter, Philomena Goins, who accompanied Mrs. Carrier to the Taylor home on the morning of January 1, 1923, a white man had visited Mrs. Taylor that day, and left shortly before Mrs. Taylor made her allegations. The black community believed that Mrs. Taylor had a romantic relationship with this unidentified white man, that they had quarrelled, and that this white man was actually responsible for Mrs. Taylor's injuries. In response to Mrs. Taylor's allegations, a group of white men, mainly residents of Sumner or workers at the Cummer sawmill, came together to search for the perpetrator. At about this time word reached Sumner from Levy County Sheriff Robert Elias Walker that a black convict named Jesse Hunter had escaped from a work crew doing road construction near Otter Creek. Jesse Hunter became the focus of the search. Later that day, Sheriff Walker sent for bloodhounds, and the trail of the fugitive was followed from behind the Taylor house in Sumner, leading the party of men toward Rosewood.
The group first came across Aaron Carrier, a black man from Rosewood who apparently was coerced into implicating Sam Carter, a forty-five year old black man who did some blacksmith work. Sheriff Walker intervened during the interrogation of Aaron Carrier and apparently sent him to the jail in Bronson for safekeeping. The dogs followed the trail to Sam Carter's house, and the search party became convinced that Sam Carter had placed the fugitive in his wagon and assisted the fugitive in an escape. The men seized Sam Carter and strung him up over a tree limb in an effort to make Carter reveal the place where he had taken the fugitive.
The role of the law enforcement officers in the search is unclear. The record indicates that Sheriff Walker was informed and probably sent for the bloodhounds from Ft. White. There is also testimony that the deputy sheriff assigned to western Levy County, Clarence Williams, who also served as a quarterboss at the Cummer sawmill, was involved in searching for the fugitive; however, it does not appear that either the sheriff or the deputy were actually members of the search party that seized Sam Carter.
Of particular interest in this regard is the testimony of Ernest Parham, who at that time was a nineteen year old resident of Sumner, working at the general store. Mr. Parham testified that after the news of Mrs. Taylor's assault on January 1, 1923 spread, tension was very high in Sumner. At the general store where he worked, they sold so much ammunition that the store's owner decided to hide his supplies and tell customers that they were sold out. Later that evening, Mr. Parham closed the store and noticed that deputy sheriff Williams, who had walked to Rosewood, had left his car parked outside. Mr. Parham drove the Williams' car by a back road from Sumner to Rosewood and located the deputy near Rosewood. At that time noise from a crowd could be heard from down the road. Mr. Parham left the deputy and walked down to where the crowd was gathered, and observed that a group of white men, many of whom he knew, had strung Sam Carter up on a tree limb in an attempt to force him to reveal information about the fugitive. Mr. Parham intervened in the situation, and the crowd of men let Carter down. Carter then took them to a place down the road where he said he let the fugitive off; however, when the dogs failed to pick up the scent, one of the men in the crowd shot and killed Sam Carter. The crowd then dispersed, and Mr. Parham returned to Sumner.
The body of Sam Carter was left on the road that night and apparently law enforcement officials did not discover the body until the following morning of Tuesday, January 2, 1923. Later that same day a coroner's jury inquest verdict signed by L.L. Johns as Justice of the Peace determined: "We the Jury after the examination of the said Sam Carter who being found lying Dead, find that the said Sam Carter came to his Death by being shot by Unknown Party so say we all."
It does not appear that any further criminal investigation was conducted into the circumstances of the death of Sam Carter.
The search for Mrs. Taylor's assailant continued. On Thursday, January 4, 1923, word reached Sumner that the man they sought was being protected by Sylvester Carrier in Rosewood. A group of white men went to the Carrier home that evening. Minnie Lee Langley and Arnett Goins, claimants in this case, were children present at the Carrier home the night of January 4, 1923, and testified to the events of that evening. The children had been told that trouble was expected and they were gathered together with other relatives at the Carrier home for their protection. They were taken to an upstairs bedroom. A group of white men approached the house and called for Sarah Carrier to come out. She did not respond. The white men then came to the porch.
 According to the testimony, one of the white men, C.P. "Poly" Wilkerson, a former quarterboss from Sumner, kicked in the door, and was immediately shot and killed by Sylvester Carrier. A second white man Henry Andrews tried to enter the house and was also shot and killed by Sylvester Carrier. The remaining white men retreated, and gunfire was exchanged. During the ensuing gunfire Sarah Carrier was shot and killed. The white men apparently ran out of ammunition, and during the respite the children were taken out of the house by older relatives, and escaped into the woods of Gulf Hammock.
It does not appear that any law enforcement officials were among the group at the Carrier home on the night of January 4, 1923. Ernest Parham testified that deputy Williams was at the hotel in Sumner that evening. Mr. Parham specifically remembered that deputy Williams was discussing the ongoing events and stated that "All hell's breaking out in Rosewood." There is nothing in the record to indicate the whereabouts of Sheriff Walker on that night.
In the morning of January 5, 1923 the bodies of Poly Wilkerson, Henry Andrews, Sarah Carrier, and another black man, reported to be Sylvester Carrier were found at the house. There is some dispute as to whether Sylvester Carrier was actually killed at Rosewood. His family believes that he escaped and members received Christmas greetings from him for many years after the shootings at Rosewood. After the killing of Poly Wilkerson and Henry Andrews, the violence escalated. Groups of white men from the surrounding areas, and some reportedly from other states, came to Rosewood. During the following days every black residence was burned. The black community fled to the woods. Two more deaths of residents of Rosewood were reported. Lexie Gordon, a woman of mixed color, was sick with typhoid fever and unable to leave Rosewood. When her home was set on fire she went out the back door and was shot and killed. James Carrier, the grandfather of Minnie Lee Langley, was reported to have been forced to dig his own grave and was then shot and killed. Another black man, Mingo Williams, was reportedly shot while chopping down a tree twenty miles away by a group of the white men going to Rosewood. Many of the white residents of the area came to the assistance of the black community. John Wright, the white owner of the general store in Rosewood, hid some of the children at his house, and arranged for a railroad car to pick up the women and children who had escaped into Gulf Hammock. Margaret Cannon testified that her father, Morris Cannon, a deputy sheriff in Levy County at the time, went into the woods and found the black woman and children and brought them to the train. They were taken to Gainesville. The black residents of Rosewood did not return.
Several years later the Cummer sawmill in Sumner burned. The company opened a new mill in Lacoochee, Florida, in Pasco County, and many of the Rosewood families moved to that area. Others dispersed to Jacksonville and Miami, and a few others moved out of state. Some of the property of the Rosewood residents apparently was lost to taxes, but there are a few records that indicate some property was later sold. At this time it is difficult to determine the role of law enforcement officers, and other local and state officials, regarding their conduct during the Rosewood violence. Media accounts state that the Governor, Cary Hardee, was aware of the events, but had gone hunting on the afternoon of January 4, 1923. It also appears that Sheriff Walker had informed the Governor that there was no need to call in National Guard troops. Although the record indicates that the National Guard had been mobilized in preceding years to keep the peace during civil disturbances, the Guard was not called to Rosewood. It further appears that the Sheriff of Alachua County organized a posse to come to Levy County to assist in keeping order, but the role of the Alachua Sheriff in these events is not clear from the record. Sheriff Walker resigned July 8, 1924 after the Rosewood incident, and was replaced by L.L. Johns, the former Justice of the Peace, who signed the coroner's verdict regarding the death of Sam Carter.
On January 29, 1923 the Governor ordered that a special grand jury investigate the violence at Rosewood. The grand jury was presided over by Judge A.V. Long of the Eighth Judicial Circuit. George DeCottes, the state attorney for the Seventh Circuit in Deland was appointed as prosecutor. On February 12, 1923 the grand jury convened in Bronson. There are no records of the grand jury. The newspaper accounts state that thirteen witnesses testified on February 13, 1923, and more witnesses were scheduled for the following day. Examination of witnesses ended on February 14, 1923, and on February 16, 1923 the grand jury stated that they were unable to find any evidence upon which to base indictments.
No charges were ever brought by the State of Florida against any person for the assault on Frances Taylor, for the killing of Sam Carter, for the deaths occurring at the Carrier home on the night of January 4, 1923, for the deaths of Lexie Gordon, James Carrier, or Mingo Williams, or for any acts of arson and theft which occurred at Rosewood, Florida.

LookML Grapher¶
As part of this tool suite, we include a LookML grapher–a tool that shows a “network diagram” of the model - explore - view
relationships. The code will also identify any orphans
i.e. views not referenced by any models or explores.
For instance, in this output diagram
where the nodes are colored as follows:
models: blue
explores: green
views: purple
orphans: orange,
we can see that the membership_facts
model has 5 explores. The first explore (engagement
) references 4 views: fact_engagement
, dim_product
, dim_date
, and dim_member
. We can also see that there is one orphaned view (called orphan
in this fake example).
Configuration¶
To run the grapher, run
python run_grapher.py --config config/grapher/config_grapher.json
where the config file has the following fields:
{
"infile_globs": [
"../somerepo/*.lkml"
],
"output": "graph.png",
"options": {
"node_size": 500,
"label_font_size": 18,
"text_angle": 30,
"image_width": 24,
"image_height" : 16
}
}
Limitations¶
While this tool might create a network diagram for any valid lkml
input repo, it is not guaranteed to be understandable or useful. YMMV. As the network gets large, overplotting of nodes can occur and makes them unreadable. Or, if your LookML is a mess and bunch of views and no models there won;t be any structure to see.
You may be able to fix some of these visualiztion issues by narrowing the file globs or you many need to modify the font size or image size (currently hard coded in lkmltools.grapher.lookml_grapher
class and not exposed in the config file. We could make this more configurable if useful.)


We want your data in whatever way it is available. We'll build out different ways to submit as we go.
Many of you may already have recordings of successful transmissions paired with GPS data.
Tweet us a link to your data: Tweet #MapTheThings
Or submit a pull request with your data in a reasonable format (CSV, JSON, XML, YAML, EDN) in the Github project/data directory.
Make certain to include GPS coordinates, RSSI and SNR values for successful TTN messages.
Let me know if your data includes attempted transmissions that failed - we're interested in that data to show packet loss.
You are welcome to create your own nodes and use them to transmit GPS coordinates to the Map The Things server.

This option is not available because I have not yet written the app or built the node.
Use the Map The Things iOS app and hardware node to submit coverage samples.
You start the node and start the app and then move around the coverage area, either as part of a specific data gathering mission or just a normal day's wandering. The app will report all attempts to send a message (via the API) as well successful transmissions via TTN. The resulting data will enable us to distinguishing between untested areas and those that have been tested and found wanting.

Introduction to Tikhonov Regularization Method

SCIENCE-BLOG
Regularization Inverse Problem
Very short comment on Tikhonov regularization
Tikhonov regularization method
This method is widely used to resolve discrete ill-posed inverse linear problems (also non-linear). The problem it is usually establish as,
where F(x) is a linear operator, therefore we may write,
The solution of the inverse discrete problem its usually described with the singular value decomposition (SVD). Then it is defined the pseudoinverse of K as,
The Tikhonov regularization propose another definition of the pseudoinverse which includes a regularization matrix and a regularization parameter ,
In order to write the last equation the generalized singular value decomposition (GSVD) is used.
Measurements with noise1
The inversion method has an additional difficulty when the measurements incorporate errors, usually modelled as Gaussian Errors. In that case the vector state solution, written as is related with the noisy measurements . The problem is formulated now as:
and the additional problem is not just how to calculate the singular values, but how different are the estimation and the true value .
However also there is a methodological problem on the definition of the solution given that is not true that always . Therefore, a new concept of solution is needed and it is usually formulated as an optimization rule:
where is the domain of the Forward Model.

History


While capitalism seems to be generally frustrated with the global spread of the Covid-19, surveillance capitalism has secretly risen with the virus explosion. In the name of security, a centralized digital regime with unchallengeable legitimacy power is now strictly monitoring people, which seems to bring about an information centralized online society.
“The Web of Phronesis” is thinking in this situation: Aristotle indicates that the phronesis (wisdom of praxis) produced by praxis can lead people to aletheuein and to achieve the solicitous circumspection. It means that there should be phronesis to manage the use of techne, so that the techne has major flaws in revealing the alethea (truth) but outside of itself could be made the best use of. According to this, we assume that to take the thought (with action) as the starting point of the techne production would construct the future of humans under the Covid-19 state of emergency, because the starting point could trigger discussions that go beyond proliferation and concentration of global technology, then fork futures.
In the previous Annual Conferences “Forces of Reticulation” (2016), “Another Walk with Lefebvre: Critique of Urbanism and Everyday Life in the Algorithmic Age” (2017), “Intelligent Urban Fabric” (2018) and “Neitizen21: Beyond Personal Account” (2019), we connected worldwide scholars and activists to construct criticism toward current network society and explore a network of practices together.
This year, in addition to the workshop and the four panels, we also call for young scholars and activists worldwide to submit papers on the five topics, and present their latest research and practices in “Young Scholars Forum”.
The Fifth Annual Conference of Network Society includes:
WestLake Mesh Network Workshop
In the end of October, Dweb Shanghai will lead the applicants to set up a wireless mesh network around the West Lake. The workshop will be open to the public. The applicants can either directly help build this network onsite or come up with the potential usage on top of it. This workshop will last two days. The open call for workshop proposals will launch in a short run.
Special Panel I. Radical Market
In this panel, we would like to trigger debates on the market, technology, national policies and free competition, seeking to reverse the inequality, especially reduced productivity, stagnation and conflicts, generated by capitalism. Cooperating with the World Young Scientist Summit (WYSS), the panel will be a part of the “Part 6.: Crisis| Introspection” of the Inter-World View at CAA. The part 6. will be held on Oct. 20 in Hangzhou. There should be hundreds of scientists and artists attending the discussion at that time.
Panel II. Internet Archive
History is a filter and a narrative truth about the past. The truths could always be footnotes to the facts, quarantined by the social reality of the time and the present. Since the establishment of the Internet Archive in 1996, information generated by the Internet has far exceeded the total amount of human history. Today, digitized files and metadata records have become the main issue of art museums and galleries. Under this circumstance, to preserve, to record and to file human civilization are critical challenges to technicalize and to externalize human history.
Panel III. Decentralized Web(DWeb)
Is the Internet ruled by oligarchies sick? How to create an Internet in which inclusive love could stand, publicness would be compatible with privacy, and everyone is welcomed? We want to shift those centralized forces back to the users, the real participant in the existing Internet. In this panel, The practitioners of Decentralized Web will be invited to share their experiences on architecting in the atlas of the future which has already taken place.
Panel IV. Crypto-ist
Although to ensure one’s privacy and security on the internet are basic human rights, the monopoly and the algorithmic improvement of social media are now preventing the netizens from seizing back their lost human rights. To help netizens retake online privacy and security needs revolutions on both economy and society. Gladly we found that there are plenty of technologies prepared for this revolution that have progressed substantially in the past decade, including public key encryption, end-to-end encryption, zero-knowledge proof, and plenty of software protocols that are used in interactions, authentications and verifications. We are aiming to achieve the ultimate possibilities within the existing social system.
Topics of Interest for Submission: Empirical research paper or practice report of Chinese local context under the four panel topics.
1.Mesh Network
2.Radical Market
3.Internet Archive
4.Decentralized Web(Dweb)
5.Crypto-ist
Because of Covid-19, gatherings in CAA are required to be decreased this year. If you are not in China, we will apply necessary materials and technological support in the course of your preparation to theonline speeches. Please don’t hesitate to contact us if you have any question about the conference.

You may think your password is secure. Maybe you have chosen an obscure word, mixed in numbers, and added a
!
to the end. Think you’re pretty safe, huh?
The truth is, you aren’t. I can crack a 5 character password in less then 139 seconds!
We have been trained over time, by
unproven security techniques, to make our passwords contain numbers and letters; sometimes even an
@
or
#
or
!
is added to the mix.
But the truth is, we are only making it harder on ourselves with passwords that are difficult to remember, but
easy to guess in a brute-force attack (automated hacking software).
Although a 128-character totally random password would be phenomenal, 8 characters is about all that can be enforced without frustrating users. However, an 8-character password comprised of uppercase, lowercase, and numbers can be cracked overnight in a real world brute-force attack.
Even though we are trained to think that a password of
Blu3D0g5
is the most secure type of password, it can still be cracked by a brute-force attack.
Bare with me while I explain… with some maths!
For every character in an alpha-numeric password there are
62
possibilities. First, you have the
26
character alphabet in lowercase, then
26
more in uppercase, and
10
digits.
26 + 26 + 10 = 62
This is to say that if you choose 8 characters,
completely at random, your password would be very secure. However, we typically take a familiar word, or couple
of words, and add some uppercase letters, or replace
e
with
3
, etc… which is
not secure.
When we calculate the Information Entropy (known as the lack of order or predictability) we can see that a completely random character set is great, but when it is derived from an English word, or contains a date, it is simply terrible. The equation looks like this:
[Password_Length] * log2([Number_of_Possibilities]) = "Information Entropy"
8 * log2(62) = "~48 bits"
# which would take almost 9,000 years at 1,000 guesses per second
But, when your password isn’t completely random, it’s not that simple.
Because the password we chose was actually two words,
blue
and
dogs,
with some uppercase and numbers mixed in, the total Entropy is
MUCH less. Something closer to
~28 bits
.
So let’s calculate what this actually means. A brute-force attacker can easily guess 1,000 times per second. The total number of options to guess can be calculated by taking the base 2 to the total number of bits.
2^28 = 268,435,456
# This is the total number of possibilities the password could be.
In theory though, an attacker only needs to guess about half the total number of options before stumbling upon the correct one. So:
268,435,456 / 2 = 134,217,728
# Total number of guesses it takes to guess your password
134,217,728 / 1,000 = ~134,218
# At 1,000 guesses per second, it takes about 134,218 seconds
134,218 / 60 = ~2,237
# Or 2,237 minutes
2,237 / 60 = ~37
# Or 37 hours to guess your password
Let’s say we use 4
random words, without any numbers, and all lowercase. For example:
yellow
tiger
note

. There are an incalculable amount of words for you to choose from, but most likely, you will choose from
about 7,000 of the most commonly used words. If you use unique words like
laggardly
or
pomological
, the total time to crack your password will increase
exponentially!
Using this new data, the Information Entropy is now calculated as:
[Number_of_words] * log2(7,000)
So, this new password now has
~51 bits
of Entropy, and using the same time calculations above, we estimate our password would take about
35,702 years
to crack at the rate of 1,000 guesses per second.
That is in stark contrast to the short 37 hours it takes to crack the
Blu3D0g5
password.
By simply increasing the length of our passwords and using words randomly mixed together, we can have the most secure passwords
that attackers will struggle to figure out, but that we can actually remember. I personally will never forget
