I'm resetting up some older hardware. I've created an Ubuntu machine with emoncms running and that appears to work fine and an pi with the RFM12Pi V2 which I can log into as well.
I have an older emonTx V3 which is flashing the red light every 10 seconds which I believe means that it is transmitting.
The issue is I've installed everything as per the setups but it shows that all the nodes are inactive. I'm not sure where to go from here?
Thanks Josh
All I get on the pi logs:

Re: Troubleshooting inactive nodes
The emonhub log shows that there is no data being sent in the request. Are there any logs corresponding to data received from the RFM12Pi? Did you setup the EmonHubJeeInterfacer? It should look similar to this:

Re: Troubleshooting inactive nodes
I believe it is, I've attached the whole thing below. I get a little green flash about every ten seconds next to the RF ACT LED on the RFMPi.
I get the red flash every ten seconds on the emonTX V3.
I just don't know what to test next or what to try to see what is happening.
Thanks Josh

I'll do some more digging around when I get time, I think I may have to do more settings to the Emonhub Config.

Re: Troubleshooting inactive nodes
I can see by the logs this is the "emonpi" variant of emonhub but the first line of your log shows "EmonHub Pre-Release Development Version (rc2.0?)" which means this is the very first "emonpi" release before the version was corrected.
I would strongly recommend updating before too much digging as it may of been fixed in production.
Tell us more about your set up, this seems an odd version to be using for a remote install since it is focused on a close local (same machine) link to the nodes module in emoncms. The original emonhub version is a direct replacement for the oemgateway you had previously.
The error seems to suggest the 12 scales do not match the 12 values, In fact I believe the confusion is because the emonTx is sending 12 bytes for 6 values and the datacodes test is being side stepped by the "datacode = h".
The scales test is then failing with a less than helpful log that should say the Scales ['1', '1', '1', '1', '0.01', '0.1', '0.1', '0.1', '0.1', '0.1', '0.1', '1'] for Values : [-504, 998, 38, 0, 240.81, 0] not suitable.
Try setting " scales = 1,1,1,1,0.01,0.1 " for node 10 or alternatively just comment out the scales line so that the default " scale = 1 " gets applied and you do the scaling in emoncms as before.
Paul
Re: Troubleshooting inactive nodes
Okay I'll give updating a go and changing some values when I get a chance.
My setup is:
EmonTx V3
Raspberry Pi with RFM12Pi
Ubuntu VM with emonCMS installed.
I bought all this about 2 years ago before the emonPi came out but moved house recently and am trying to reinstall everything. Was all working fine before the more.

Begin to believe that you are not alone and that help is available for you and your children.
Talk in confidence to someone you trust: a relative, friend, parish priest, deacon, religious sister or brother, or lay minister.
If you choose to stay in the situation, at least for now, set up a plan of action to ensure your safety. This includes hiding a car key, personal documents, and some money in a safe place and locating somewhere to go in an emergency.
Find out about resources in your area that offer help to battered women and their children. The phone book lists numbers to call in your local area. Your diocesan Catholic Charities office or family life office can help. Catholic Charities often has qualified counselors on staff and can provide emergency assistance and other kinds of help.
Admit that the abuse is your problem, not your partner's, and have the manly courage to seek help. Begin to believe that you can change your behavior if you choose to do so.
Be willing to reach out for help. Talk to someone you trust who can help you evaluate the situation. Contact Catholic Charities or other church or community agencies for the name of a program for abusers.
Keep in mind that the Church is available to help you. Part of the mission Jesus entrusted to us is to offer healing when it is needed. Contact your parish.
Find alternative ways to act when you become frustrated or angry. Talk to other people who have overcome abusive behavior. Find out what they did and how they did it.
Learn the signs of domestic violence because your friend, family member or coworker may be exhibiting these. If you have school age children, educate them and discuss with them the telltale signs of abuse – they may have schoolmates exhibiting such signs.
If you witness acts of domestic violence, or you strongly suspect a situation of domestic violence, do not turn away. You can call 911.


The giant panda (Ailuropoda melanoleuca, literally "black and white cat-foot"; Chinese: 大熊猫; pinyin: dà xióng māo, literally "big bear cat"),[4] also known as panda bear or simply panda, is a bear[5] native to south central China.[1] It is easily recognized by the large, distinctive black patches around its eyes, over the ears, and across its round body. The name "giant panda" is sometimes used to distinguish it from the unrelated red panda. Though it belongs to the order Carnivora, the giant panda's diet is over 99% bamboo.

Divides (unsigned) the value in the AX, DX:AX, or EDX:EAX registers (dividend) by the source operand (divisor) and stores the result in the AX (AH:AL), DX:AX, or EDX:EAX registers.
DIV Action
| Operand Size | Dividend | Divisor | Quotient | Remainder | Maximum Quotient |
| Word/byte | AX | r/m8 | AL | AH | 2^8 - 1 |
| Doubleword/word | DX:AX | r/m16 | AX | DX | 2^16 - 1 |
| Quadword/doubleword | EDX:EAX | r/m32 | EAX | EDX | 2^32 - 1 |
The source operand can be a general-purpose register or a memory location. The action of this instruction depends on the operand size (dividend/divisor). See the table above.
Non-integral results are truncated (chopped) towards 0. The remainder is always less than the divisor in magnitude. Overflow is indicated with the #DE (divide error) exception rather than with the CF flag.

Labdevicedriver Framework
|
A open source framewok handling interactions with typical laboratory devices. The framework consists of a communication layer and a device layer. A bottom layer for communication that can handle GPIB, Ethernet, and GPIB-over-Ethernet communication is the base of the framework. On top typical SCPI (Standard Commands for Programmable Instruments) commands are implemented to free the user from searching through endless user manuals. This framework can be used as stand-alone or can yield the basis for all Matlab measurement applications.
** Use with Ethernet **
** Use with GPIB **
Interface converters require an initialisation of the interface converter object first, before initialising the device class.
Superclass for all lab Devices
Configs: Eg. default device properties
Abstract Interface Classes for the different device types. The classes should be used to define common interfaces for all devices of one specific type. The abstract class assures the same method or property names over all devices of one device type eg. vector network analyser.
Contains all interface converter objects eg. eth2gpib.
Contains all low level functionality like opening and closing connection to device. Namespaces (contianing + in front of foldername) seperate open and close functions of the interfaces (e.g. eth or gpib).
To integrate the labdevice framework in an existing repo as a submodule:
Keep in mind: git pull on the main repository does not update the submodule. After git pull you need to execute
to update the submodule after running git pull.

rdbService is an example EPICS V4 relational database service.
Warning: rdbService does not run as delivered with EPICS V4 release 4.6
In addition to the components delivered with release 4.6, it requires access to a relational database. This example was created by Greg White at LCLS and was used to access an LCLS Oracle database. The example is similar to what was delivered with EPICS V4 release 4.5. The following are differences:
If someone has questions about this example please contact Greg White at LCLS.
rdbService is a minimal EPICS V4 service which demonstrates the use of EPICS V4 RPC support. It implements a relational database service, which accesses a relational database on behalf of a pvAccess client, shows how users can trivially get data from a db like Oracle.
Auth: Greg White, 13-Oct-2011<EMAIL_ADDRESS>/<EMAIL_ADDRESS>Mod: Greg White, 9-Nov-2012<EMAIL_ADDRESS>/<EMAIL_ADDRESS>Updated for EPICS V4 beta 2 APIs and techniques.
The following is an example of running the client. This examples gets details about all the devices in the SwissFEL Test accelerator from the PSI Oracle database, and prints them to the terminal. For brevity, only 6 rows of the output are included here:

rdbService is a minimum client and server implemented in the EPICS V4 RPC "framework" intended to show programming required to implement a service that gets data out of a relational database, like Oracle. The server side receives a named request for data, such as "swissFEL:allQUADs" and finds the SQL SELECT (or equivalent) database query for that name. It then executes the database query, and returns the resulting table of data to the client.
RdbService illustrates mapping a JDBC ResultSet returned by a relational DB query, to a PVStructure (in fact, specifically an early version of the NTTable normative type), extracting the data from a PVStructure (see use of GetHelper class) and a tabular data formatting utility useful for printing the tabular contents of an NTTable (see use of NamedValues class).

Do the following:
Most importantly, work out how your rdbService server side will translate the names it is given, like "myaccelerators:magnetdata" into a SQL SELECT statement. As shipped rdbService does this in RdbServiceConnection, by looking up the name it was given in a trivial 2-column Oracle table called EIDA_NAMES (see RdbServiceFactory.java). Eg:
sls:alldevices Select * from sls.alldevices_v sls:allmagnets Select * from sls.magnetdevice_v order by domain,ds sls:allmagnetdata Select * from sls.magnetddata_v order by type swissfeltest:sectiontre Select * from swissfel.swissfel_test_tree_v
Then edit your version of rdbServiceRunner to pass the right Java Properties (-Ds)
This section describes how you start server and client sides of the rdb Service.
Start the server side first.
If you encounter issues, you might start with
troubleshooting
To start the rdbService server
cd ~/Development/epicsV4/workspace_hg_beta2/exampleJava/src/services/rdbService
./rdbServerRunnerYou should see, at the end of the startup echos, "Running server ..."
In another window from the server
% cd ~/Development/epicsV4/workspace_hg_beta2/exampleJava/src/services/rdbService
% ./rdbClientRunner swissfeltest:alldiagAlternatively, use the getRdb wrapper of the client side executable:
% getRdb swissfeltest:alldiag
At PSI there is an Oracle database for SLS and anther for SWissFEL projects. A single oracle "schema" named EIDA has been granted read access to both of these. The example rdbService uses that schema to access data in the other 2 schema.
The name to SQL query mapping is stored, in this example, within the EIDA schema itself (though other implementations may like to keep the mapping elsewhere, such as in a directory service). Specifically, EIDA_NAMES is a table in EIDA, which just has 2 important columns, the "names" of queries (what a user asks for), and the SQL statement equivalent to that query (the SQL that the rdb Server executes when the user asks for a given name. Here is an extract from EIDA_NAMES:
NAME QRY ------------------------ --------------------------------------------------------------- sls:alldevices Select * from sls.alldevices_v sls:allmagnets Select * from sls.magnetdevice_v order by domain,ds sls:allmagnetdata Select * from sls.magnetddata_v order by type swissfeltest:sectiontree Select * from swissfel.swissfel_test_tree_v swissfeltest:alldevices Select * from swissfel.feltest_heilig_v order by PREFIX,"Z0(M)" <many rows snipped for clarity>
So, when a user asks for, for example, swissfeltest:alldevices, the rdbService first looks in EIDA_NAMES to find the QRY whose NAME is swissfeltest:alldevices, and then it executes the SQL statement it finds 'Select * from swissfel.feltest_heilig_v order by PREFIX,"Z0(M)". Simple as that.

What are their names? And until then, I can never die? Come, Comrade Bender! We must take to the streets! I barely knew Philip, but as a clergyman I have no problem telling his most intimate friends all about him. That could be 'my' beautiful soul sitting naked on a couch.
Fatal. I'm Santa Claus! Bender, I didn't know you liked cooking. That's so cute.
Anyone who laughs is a communist! Well I'da done better, but it's plum hard pleading a case while awaiting trial for that there incompetence. Why, those are the Grunka-Lunkas! They work here in the Slurm factory. Bender?!
No, just a regular mistake. Hello, little man.  Alright, let's mafia things up a bit. Joey, burn down the ship. Clamps, burn down the crew.
And then the battle's not so bad? I'm sure those windmills will keep them cool. And from now on you're all named Bender Jr.

ntpdate
Section: Maintenance Commands (8)Index Return to Main Contents
NAME
ntpdate - set the date and time via NTPDisclaimer: The functionality of this program is now available in the ntpd program. See the -q command line option in the ntpd - Network Time Protocol (NTP) daemon page. After a suitable period of mourning, the ntpdate program is to be retired from this distribution
SYNOPSIS
ntpdate [ -46bBdqsuv ] [ -a key ] [ -e authdelay ] [ -k keyfile ] [ -o version ] [ -p samples ] [ -t timeout ] [ -U user_name ] server [ ... ]DESCRIPTION
ntpdate sets the local date and time by polling the Network Time Protocol (NTP) server(s) given as the server arguments to determine the correct time. It must be run as root on the local host. A number of samples are obtained from each of the servers specified and a subset of the NTP clock filter and selection algorithms are applied to select the best of these. Note that the accuracy and reliability of ntpdate depends on the number of servers, the number of polls each time it is run and the interval between runs.
ntpdate can be run manually as necessary to set the host clock, or it can be run from the host startup script to set the clock at boot time. This is useful in some cases to set the clock initially before starting the NTP daemon ntpd[char46] It is also possible to run ntpdate from a cron script. However, it is important to note that ntpdate with contrived cron scripts is no substitute for the NTP daemon, which uses sophisticated algorithms to maximize accuracy and reliability while minimizing resource use. Finally, since ntpdate does not discipline the host clock frequency as does ntpd, the accuracy using ntpdate is limited.
Time adjustments are made by ntpdate in one of two ways. If ntpdate determines the clock is in error more than 0.5 second it will simply step the time by calling the system settimeofday() routine. If the error is less than 0.5 seconds, it will slew the time by calling the system adjtime() routine. The latter technique is less disruptive and more accurate when the error is small, and works quite well when ntpdate is run by cron every hour or two.
ntpdate will decline to set the date if an NTP server daemon (e.g., ntpd) is running on the same host. When running ntpdate on a regular basis from cron as an alternative to running a daemon, doing so once every hour or two will result in precise enough timekeeping to avoid stepping the clock.
Note that in contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace.
If NetInfo support is compiled into ntpdate, then the server argument is optional if ntpdate can find a time server in the NetInfo configuration for ntpd[char46]
COMMAND LINE OPTIONS
-
- -4
- Force DNS resolution of following host names on the command line to the IPv4 namespace.
- -6
- Force DNS resolution of following host names on the command line to the IPv6 namespace.
- -a key
- Enable the authentication function and specify the key identifier to be used for authentication as the argument key[char46] The keys and key identifiers must match in both the client and server key files. The default is to disable the authentication function.
- -B
- Force the time to always be slewed using the adjtime() system call, even if the measured offset is greater than +-500 ms. The default is to step the time using settimeofday() if the offset is greater than +-500 ms. Note that, if the offset is much greater than +-500 ms in this case, that it can take a long time (hours) to slew the clock to the correct value. During this time. the host should not be used to synchronize clients.
- -b
- Force the time to be stepped using the settimeofday() system call, rather than slewed (default) using the adjtime() system call. This option should be used when called from a startup file at boot time.
- -d
- Enable the debugging mode, in which ntpdate will go through all the steps, but not adjust the local clock. Information useful for general debugging will also be printed.
- -e authdelay
- Specify the processing delay to perform an authentication function as the value authdelay, in seconds and fraction (see ntpd for details). This number is usually small enough to be negligible for most purposes, though specifying a value may improve timekeeping on very slow CPU's.
- -k keyfile
- Specify the path for the authentication key file as the string keyfile[char46] The default is /etc/ntp/keys[char46] This file should be in the format described in ntpd[char46]
- -o version
- Specify the NTP version for outgoing packets as the integer version, which can be 1 or 2. The default is 4. This allows ntpdate to be used with older NTP versions.
- -p samples
- Specify the number of samples to be acquired from each server as the integer samples, with values from 1 to 8 inclusive. The default is 4.
- -q
- Query only - don't set the clock.
- -s
- Divert logging output from the standard output (default) to the system syslog facility. This is designed primarily for convenience of cron scripts.
- -t timeout
- Specify the maximum time waiting for a server response as the value timeout, in seconds and fraction. The value is is rounded to a multiple of 0.2 seconds. The default is 1 second, a value suitable for polling across a LAN.
- -u
- Direct ntpdate to use an unprivileged port for outgoing packets. This is most useful when behind a firewall that blocks incoming traffic to privileged ports, and you want to synchronize with hosts beyond the firewall. Note that the -d option always uses unprivileged ports.
- -v
- Be verbose. This option will cause ntpdate's version identification string to be logged.
- -U user_name
- ntpdate process drops root privileges and changes user ID to user_name and group ID to the primary group of server_user[char46]
DIAGNOSTICS
ntpdate's exit status is zero if it finds a server and updates the clock, and nonzero otherwise.FILES
/etc/ntp/keys - encryption keys used by ntpdate[char46]BUGS
The slew adjustment is actually 50% larger than the measured offset, since this (it is argued) will tend to keep a badly drifting clock more accurate. This is probably not a good idea and may cause a troubling hunt for some values of the kernel variables tick and tickadj[char46]SEE ALSO

As Yogi Berra said, you can observe a lot just by watching. Watching how people do things is a great way to learn their goals and values, and come up with design insight. We call this needfinding. This assignment helps you train your eyes and ears to come up with design ideas. Your goal is to uncover user needs, breakdowns, clever hacks, and opportunities for improvement.
You will ultimately be designing a web-based service or application, you don't need to restrict your observation to people using computers and the Web. If you're designing for an activity that people don't currently use computers for--or where non-digital tools have benefits--then observe people doing the task as they do it now. Observing the strengths and weaknesses of analog tools can inspire ideas for the digital world. Where people are using software, remember to observe and interview people in situ -- using their computer, their software, in their environment, doing their activities. Context matters. If you have mobility limitations, perform your observations and interviews over email, phone, Skype, and/or video chat. If for whatever reason you're interested in activities that are tough to observe -- maybe because they're infrequent -- you can augment your interviews with diary studies.
Make a list of types of people you might interview and situations you might observe to come up with design insights. Think about different types of everyday users, marginalized users, and extreme users. Also think about other stakeholders in the ecosystem. Think about the characteristics of these users.
For example, this IDEO design team was asked to redesign the grocery shopping cart. Their interviewees included not just everyday users, but also extreme users like professional shoppers and other stakeholders like store managers. Often, lead users or extreme users have come up with better solutions and creative tricks. Interviewing and observing marginalized users not only helps us create more inclusive designs, it also often highlights issues that everyone has to varying degrees.
Select three individuals to observe. Choose people who are not similar to yourself in some way (for example, they are studying different discipline, working a different type of job, have a different family situation).
Your goal is to observe the successes, breakdowns, and latent opportunities that occur when computers are used, not used, or could be used to support your chosen activity. Ask them to participate in this assignment and get permission from them. Be sure you coordinate with your participants to select a time that will be rich for observations.
Tell the participants to perform the task as realistically as possible, while communicating to you as appropriate. Utilize the strategies we talked about in lecture to help you. During the observation, in addition to taking notes, use digital photographs or sketches to document activities, but do not use a video camera. This is because your choice of moments to capture with a photograph or sketch is what is important, as it shows specific successes and breakdowns.
After the observations, spend 10 to 15 minutes interviewing your participants about the activity you observed. It should take you approximately two hours total to make all three observations if you have planned carefully. It will take longer if you haven’t!
Remember, these photos and sketches are meant to document your actual observations:
After observing people, go over your findings and use them to brainstorm a list specific user needs: opportunities for design innovation that would enable computers to better support the activity you observed. Once again, go for volume when you brainstorm and include as many people as you want to help you. Brainstorming is a group activity and should be fun! You are free to brainstorm with anyone around you to generate as many interesting ideas as possible.
All ideas are good ones at this stage, and you should generate at least 15 of them: go for volume.
You are not looking for solutions yet: focus on user needs and goals only. An example of a need might be "Sometimes, when Scott takes the Caltrain home, there is no room for his bike and he has to wait for the next one. Scott needs a way to plan what train to take based on how much room is available in the bike car".
It is helpful to use to phrases "needs a way to" or "needs to be able to" as you list your user needs.
by Mike Davison, Community TA and UX Project Manager
Needfinding is probably the most important part of any UX Designer's arsenal. Without it, your design team could spend months designing a solution that completely misses the point. You will be surprised at how much you can learn, especially when you vary the audience.
Take the smartphone. In all likelihood, you will have seen an elderly person press the screen harder and more slowly when it does not respond as they had expected. Needfinding research has suggested that this relates to 50s, 60s and 70s technology - the technology this age group are familiar with...this technology often does yield a different result if you press harder.
Why is this useful? Well perhaps we could develop interfaces that took into account the pressure the user applies, and not just where they apply it? How could we make the interface itself easier for the elderly user? Needfinding is a very powerful way to generate ideas.
Here are two student examples from last year. Keep in mind that the assignment was slightly different last year.

ActiveRecord::ConnectionAdapters::AbstractAdapter
|
| Defined in: | activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb |
Overview
The PostgreSQL adapter works with the native C (bitbucket.org/ged/ruby-pg) driver.
Options:
-
:host
- Defaults to a Unix-domain socket in /tmp. On machines without Unix-domain sockets, the default is to connect to localhost. -
:port
- Defaults to 5432. -
:username
- Defaults to be the same as the operating system name of the user running the application. -
:password
- Password to be used if the server demands password authentication. -
:database
- Defaults to be the same as the user name. -
:schema_search_path
- An optional schema search path for the connection given as a string of comma-separated schema names. This is backward-compatible with the:schema_order
option. -
:encoding
- An optional client encoding that is used in aSET client_encoding TO <encoding>
call on the connection. -
:min_messages
- An optional client min messages that is used in aSET client_min_messages TO <min_messages>
call on the connection. -
:variables
- An optional hash of additional parameters that will be used inSET SESSION key = val
calls on the connection. -
:insert_returning
- An optional boolean to control the use ofRETURNING
forINSERT
statements defaults to true.
Any further options are used as connection parameters to libpq. See www.postgresql.org/docs/9.1/static/libpq-connect.html for the list of parameters.
In addition, default connection parameters of libpq can be set per environment variables. See www.postgresql.org/docs/9.1/static/libpq-envars.html .

Code of Conduct
SRCCON SAFETY HELPLINE: If you would like to make any reports after the event, please email us at<EMAIL_ADDRESS>SRCCON and OpenNews are committed to providing a welcoming and harassment-free environment for participants of all races, gender and trans statuses, sexual orientations, physical abilities, physical appearances, and beliefs. We’ve written this code of conduct not because we expect bad behavior from our community—which, in our experience, is overwhelmingly kind and civil—but because we believe a clear code of conduct is one necessary part of building a respectful community space.
SRCCON participants agree to:
- Be considerate in speech and actions, and actively seek to acknowledge and respect the boundaries of fellow attendees.
- Refrain from demeaning, discriminatory, or harassing behavior and speech. Harassment includes, but is not limited to: deliberate intimidation; stalking; unwanted photography or recording; sustained or willful disruption of talks or other events; inappropriate physical contact; use of sexual or discriminatory imagery, comments, or jokes; and unwelcome sexual attention. If you feel that someone has harassed you or otherwise treated you inappropriately, please alert any member of the conference team in person, via the team phone/text line, or via email.
- Take care of each other. Alert a member of the conference team if you notice a dangerous situation, someone in distress, or violations of this code of conduct, even if they seem inconsequential.
If any attendee engages in harassing behavior, the conference organizers may take any lawful action we deem appropriate, including but not limited to warning the offender or asking the offender to leave the conference. (If you feel you have been unfairly accused of violating this code of conduct, you should contact the conference team with a concise description of your grievance; any grievances filed will be considered by the entire OpenNews team.)
This code of conduct covers all of SRCCON, including the evening program. During SRCCON, we will publicize a contact email and phone number, in addition to pointing out the staff in matching t-shirts so you know who to contact if you see or experience an issue.
We welcome your feedback on this and every other aspect of SRCCON, and we thank you for working with us to make it a safe, enjoyable, and friendly experience for everyone who participates.

You can add and remove elements from shuffle after it has been created. This also works for infinite scrolling.
Wherever you add the element in the DOM is where it will show up in the grid (assuming you’re using the default sort-by-dom-order). With this in mind, you can append, prepend, or insert elements wherever you need to get them to show up in the right order.
/**
* Create some DOM elements, append them to the shuffle container, then notify
* shuffle about the new items. You could also insert the HTML as a string.
*/
Demo.prototype.onAppendBoxes = function () {
var items = this._getArrayOfElementsToAdd();
items.forEach(function (item) {
this.shuffle.element.appendChild(item);
}, this);
// Tell shuffle items have been appended.
// It expects an array of elements as the parameter.
this.shuffle.add(items);
};
Shuffle will animate the element away and then remove it from the DOM once it's finished. It will then emit the Shuffle.EventType.REMOVED
custom event with the array of elements in event.detail.collection
.
this.shuffle.remove([element1, element2]);
Check out the adding and removing demo.

The Negotiator by Curtis Edmonds --<EMAIL_ADDRESS>They didn't have a lot of the scenes I wanted to see in The Negotiator, but there was one scene I particularly missed. It was the scene where Chief Deputy United States Marshal Samuel Gerard is sitting on his couch, watching the mayhem of the movie on WGN.
The way this movie was advertised was as a cat-and-mouse game between two professional hostage negotiators. Samuel L. Jackson as framed cop Danny Roman versus Kevin Spacey as outside negotiator Chris Sabian. It all looked so promising, with two of Hollywood's best actors going mano-a-mano in a Chicago-themed action flick, just like in Jeb Stuart's script for The Fugitive. And throw in a bit of Stuart's Die Hard script, with Jackson as the lone hero cop trapped in a tall building... it looked very, very promising. What a shame that The Negotiator is in the hands of amateurs.
The premise of the movie is that it's a duel between the hostage negotiators. Jackson, wrongfully accused of theft and murder, snaps and takes the police department's internal affairs department hostage. He calls on Spacey to serve as his personal negotiator (after a very funny scene where he pokes holes in the confidence of the poor schmuck originally designed to talk him down). So, this ought to be a great battle of wits, right? Right?
The Negotiator would have us believe that the most important skill of a good hostage negotiator is lying. You can make a good movie about lying -- say, House of Games or The Sting -- but it's hard to make a good action movie about lying. And especially here, where all the lying concerns finding the evidence that will free Roman of the charges against him. We already know he's telling the truth, and we don't much care about the scandal, so that's just not interesting.
What I would have like to have seen is a little more of the tricks of the trade being displayed. The only time we really see the Chicago PD being sneaky is when they try to snake mini-cameras to view the hostages -- Jackson sees them, as any reasonably observant person would, and yanks them out. There's nothing really improvisational or imaginative about the whole setup. (Contrast the imaginative hostage negotiation between Bill Murray and Jason Robards in Quick Change.) Throw in a couple of unrealistic plot twists (totally unworthy of Sam Gerard or any other law enforcement professional) and what you end up with is a mess of a movie.
Jackson's best performances have always come when he has a character to play that's basically unappealing. For example, both Jules in Pulp Fiction, and Ordell Robbie in Jackie Brown were both very bad, very unlikable dudes -- but the audience was sympathetic to both of them, in a way, because Jackson's sheer force of talent makes them magnetic. Danny Roman is meant to be appealing -- the audience has to be on his side the whole movie -- but he's never magnetic. There's only one little scene where Jackson is allowed to go over the edge into unlikability -- and it's a cheat. Not a great performance, although it's many, many fathoms better than what we saw when he was at the bottom of the ocean in Sphere.
If Jackson doesn't live up to his potential in The Negotiator, Spacey steps all over his and grinds it into the mud. Spacey is a great actor, capable of a wide range of parts, and what they've done here is put him on Macho Mountain without any rope. Other than a too-long cutesy scene between his wife and daughter that's completely contrived to establish his credentials as a negotiator, Spacey is made to participate in scene after scene of macho posturing. He's consistently in screaming matches with Jackson and the cops. His voice must have been really, really hoarse after production was completed.
The rest of the cast is a tribute to the majesty and power of typecasting. John Spencer, so good as Harrison Ford's cop friend in Presumed Innocent, is the chief of police here. The late, great J.T. Walsh plays an oily creep who knows more than he's saying. Ron Rifkin plays a devious-but-bland cop in the same manner as his guest turn on ER not too long ago.
Speaking of ER, here's a memo for Anthony Edwards: make sure your agent sees this movie, because you don't want to end up like David Morse. Remember him? He was the sensitive-yet-tough doctor who led the ensemble cast on the hospital drama St. Elsewhere. Unfortunately, he's only able now to get parts as mindless toughs for some reason. Something to think about, OK?
There really isn't much that wrong with The Negotiator, and I don't want to talk you down from your stadium seat. It's perfectly serviceable, mindless summer movie entertainment. But it could have been so much better, and that's a shame.
